Description

  The present invention relates to a gaming machine that determines by lottery whether or not to give a game profit to a player.

  A slot machine as a gaming machine is provided with a plurality of gaming states and performance states that differ in the player's degree of advantage (game profit) as the game progresses. For example, there is a slot machine that adopts a specification in which a symbol combination corresponding to a bonus combination is displayed on an active line to shift from a normal gaming state to a bonus gaming state in which a player can easily acquire medals.

  When an unexpected power interruption occurs in such a slot machine, it is necessary to restore the state before the power interruption. Therefore, when the power is turned on, it is checked whether or not the final storage content stored in the backup RAM area is normal based on the checksum stored in the backup RAM area. A technique for returning the control state to the state before power interruption based on the contents is disclosed (for example, Patent Document 1).

JP 2002-095840 A

  The abnormality based on the checksum as described above can be caused not only by a malfunction of the slot machine but also by an illegal act by a third party. Therefore, the slot machine also requires security-related processing for the purpose of preventing fraud. In the slot machine, various signal processing related to the test specified by the gaming machine rules must also be performed. Such processing can be executed on the main control board if it is arranged in a use area within a prescribed capacity that combines a control area (for example, 4.5 kbytes) and a data area (for example, 3.0 kbytes) in the storage area of the main control board. Processing is limited.

  In particular, when winning a winning category (hereinafter referred to as a selected winning category) including a winning role with a large gaming profit (hereinafter referred to as a selected winning category), an operation mode of a stop switch that is a winning condition for the selected winning role (hereinafter referred to as a winning category) (Hereinafter referred to as the correct operation mode) (hereinafter, such an effect that informs the operation mode that is the winning condition for the predetermined winning combination is simply referred to as an auxiliary effect), and the symbol combination corresponding to the selected winning combination is determined. When the AT control state in which the so-called AT (assist time) is executed can be managed in the main control board, which can be easily displayed on the active line by the player, or the frequency of transition to such an AT effect state The main control board manages the stay ratio (advantageous section ratio) of the number of games in the section (with the performance related to the instruction function) to the total number in order to prevent the bias. If you, by the process, there is a possibility that use area is further squeezed.

  Regardless of the execution of AT, the time from when the stop switch operation is enabled in the previous game to the time when the disabled stop switch operation is enabled in the current game is extended from the specified time. In the meantime, in the case of performing a reel effect in which the reel is rotated in various manners, there is a possibility that the use area is further pressed by the process.

  Therefore, it is conceivable to describe such processing in a separate area which is a storage area different from the use area where the storage capacity is limited. However, there is a possibility that the fairness of the slot machine cannot be ensured by dividing the roles into a plurality of storage areas.

  The present invention has been made in view of such problems, and an object thereof is to provide a gaming machine capable of appropriately sharing roles between a use area and another area while ensuring the fairness of the slot machine.

To solve the above Symbol problem use, a CPU, a storage capacity is limited, a program in which use program for executing a game control process that controls the progress of the game in the limited in storage capacity is stored An area is a program for executing a process that does not affect the progress of the game other than the game control process, and is explicitly distinguished from another area in which another program modularized in units of functions is stored. In another gaming machine of the present invention comprising storage areas respectively arranged in the areas, the internal register of the CPU includes a table register and a back register that can exchange data with the table register, and the use program Then, the use of the back register is restricted, and the CPU prohibits interrupts according to the program stored in the use area and is stored in the separate area. The separate program is called through a specified call destination address, and according to the separate program, only the pair register of the front register and the pair register of the back register are exchanged at once by two exchange instructions, and other than the game control process The process that does not affect the progress of the game is executed, only the pair register of the front register and the pair register of the back register are exchanged at once by the exchange instruction of 2, and the program stored in the use area is Control area where the game control process returns until reaching the interval of the interrupt process, interrupt is permitted when returning to the program stored in the use area, and the use program of the use area is arranged In this case, it is prohibited to update the data area of the different area, and it is permitted to refer to the data area of the used area. In a control area in which the other program in another area is arranged, it is prohibited to call a subroutine in the control area of the used area, prohibit updating of the data area of the used area, and It is allowed to refer to the data area.

  The CPU may return to the use program after permitting the interrupt.

  According to the present invention, it is possible to appropriately divide roles between a use area and another area while ensuring the fairness of the slot machine.

(Table used in main control board 200)
FIG. 5 is an explanatory diagram for explaining a winning combination, and FIGS. 6 and 7 are explanatory diagrams for explaining a winning type lottery table.

  In the slot machine 100, as will be described in detail later, a plurality of types of game states and effect states are provided, and the game state and effect states are shifted according to the progress of the game. In the main control board 200, a plurality of winning type lottery tables and the like corresponding to the gaming state managed and controlled by the gaming state control means 312 are stored in the main ROM 200b. The winning type lottery means 304 stores the corresponding winning type lottery table in the main ROM 200b according to the current set value (incrementally indicating ease of obtaining gaming profits) stored in the main RAM 200c and the current gaming state. Based on the extracted winning type lottery table, it is determined which winning type in the winning type lottery table corresponds to the winning type lottery random number acquired in response to the operation signal of the start switch 118.

  Here, the winning combination that constitutes the winning category extracted from the winning category lottery table includes a replay role, a small role, and a bonus role. When the symbol combination corresponding to the replay combination is displayed on the active line A, the replay combination is a combination that allows the player to execute the game again without making a new bet of medals by the player. The small combination is a combination that allows a predetermined number of medals to be paid out according to the symbol combination by displaying the symbol combination corresponding to the small combination on the active line A. The bonus combination is a combination that allows the gaming state managed by the gaming state control means 312 to shift to the bonus gaming state by displaying the symbol combination corresponding to the bonus combination on the active line A. .

  As shown in FIG. 5, the winning combination in the present embodiment is the winning combination “Transition Replay 1” to “Transition Replay 4”, “Normal Replay 1” to “Normal Replay 3”, and “Cherry Replay 1”. , “Cherry Replay 2”, “BAR Burning Replay”, “BAR Matched Replay”, “Chance Replay” (hereinafter, these 12 replay roles may be simply abbreviated as “Winning Replay”). .

  In addition, as the small roles, the winning roles “1 single role 1” to “1 single role 16” (hereinafter, the 16 small roles may be simply abbreviated as the winning role “1 single role”), and the winning role “Bell” 1 ”to“ Bell 5 ”(hereinafter, the five small roles may be simply abbreviated as“ Bell ”), the winning role“ Cherry ”, the winning roles“ Watermelon 1 ”to“ Watermelon 4 ”(hereinafter,“ Bell ”) The four small roles may be simply abbreviated as “Watermelon”, and the winning roles “Reach eyes 1” to “Reach eyes 3” (hereinafter, these three small roles are simply referred to as “Reach eyes”. May be abbreviated as).

  In addition, winning combinations “RBB1”, “RBB2”, “CBB1”, and “CBB2” (hereinafter, these four bonus combinations may be simply abbreviated as winning combination “BB”) are provided as bonus combinations. . In FIG. 5, one or a plurality of symbols constituting each winning combination is associated with each of the left reel 110a, the middle reel 110b, and the right reel 110c. Note that “ANY” in FIG. 5 indicates that any symbol may be stopped on the corresponding effective line A. In addition, the winning roles “Cherry Replay 1”, “Cherry Replay 2”, “Chance Replay”, “Cherry”, and “Watermelon” are benefits (game profits) that can be obtained from other winning roles except the winning role “BB”. Is a so-called rare role that is set to be high.

  Here, in the present embodiment, when the symbols that constitute the symbol combination corresponding to the winning combination that can be won are on the active line A when the stop switch 120 is operated by the player, the reel control means By 306, stop control is performed so that the symbol stops on the effective line A. In addition, when the stop switch 120 is operated, the symbols constituting the symbol combination corresponding to the winning combination that can be won are not on the active line A, but the symbols in the direction opposite to the rotation direction of the reel 110 are four frames. If it is within the range corresponding to the minute (withdrawal range), the reel control means 306 turns the number of symbols away to the number of sliding symbols, and the symbols constituting the symbol combination corresponding to the winning combination are valid. Stop control is performed so as to stop after maintaining the rotation by the number of sliding frames so as to be drawn onto the line A. In addition, when there are a plurality of symbols corresponding to the winning combination that can be won in the reel 110 and all of them are within the pull-in range of the reel 110, any symbol is assigned to the active line A according to a predetermined priority order. It is determined whether or not the drawing is to be pulled up, and stop control is performed so as to stop after maintaining the rotation by the number of sliding frames so that the prioritized symbol is drawn onto the effective line A. If the symbol constituting the symbol combination corresponding to the winning combination other than the winning winning combination is on the active line A when the stop switch 120 is pressed, the reel control means 306 controls the symbol combination. So as not to stop on the effective line A, so-called kicking processing is also executed in parallel. Further, as will be described later, when the operation mode (operation order or operation timing) is set as a winning condition for the winning combination included in the winning type, the reel control means 306 determines the winning combination according to the player's operating mode. The symbol combination corresponding to is controlled so as to be displayed on the effective line A.

  For example, the symbol combinations corresponding to the winning roles “Transition Replay 1” to “Transition Replay 4”, the winning roles “Normal Replay 1” to “Normal Replay 3”, and the winning roles “Bell 1” to “Bell 5” are configured. The symbols to be displayed are arranged on each reel 110 so that they can be displayed on the effective line A by the above stop control. Such a winning combination may be expressed as PB = 1. On the other hand, for example, the symbols constituting the symbol combination corresponding to the winning combination “Cherry”, the winning combination “Watermelon”, and the winning combination “BB” are not necessarily displayed on the active line A by the above stop control in each reel 110. Since they are not arranged as possible, so-called oversight may occur. Such a winning combination may be expressed as PB ≠ 1.

  As shown in FIG. 6 and FIG. 7, in the winning type lottery table, a plurality of winning areas are divided, and the winning type that is the subject of the lottery differs depending on the gaming state, and whether or not there is a loss (unwinning). Or 6 and 7, each gaming state (RT0 gaming state (RT0), RT1 gaming state (RT1), RT2 gaming state (RT2), RT3 gaming state (RT3), RT4 gaming state (RT4), internal medium gaming state (Inside), a bonus gaming state (BB1) in which the winning combination “RBB1” has won, a bonus gaming state in which the winning combination “RBB2” has won (BB2), a bonus gaming state in which the winning combination “CBB” has won (CBB1), The winning area (winning type) assigned for each bonus game state (CBB2) won by the winning combination “CBB2” is represented by “O” or “●”. A corresponding winning type lottery table is stored in the main ROM 200b. “○” indicates that there is no setting difference (no difference for each set value) in the winning probability of that winning type, and “●” indicates that there is a setting difference in the winning probability of that winning type. It indicates that the selected difference is the selected category. In the winning type lottery table, each of the partitioned winning areas is associated with a predetermined number (winning range value) that is a numerical value indicating the winning range and the winning type, and all assigned to each gaming state. The total number of winning areas is the total number of winning type random numbers (65536). Based on the gaming state at that time, the winning type lottery means 304 sequentially obtains a number from the higher number of the plurality of winning areas in the winning type lottery table, and the number is determined as a winning type lottery random number. When the subtraction value is less than 0, the winning type associated with the winning area at that time is used as the lottery result of the winning type lottery.

  According to the winning type lottery tables of FIGS. 6 and 7, for example, the winning area 1 is associated with the winning type “losing”, and if the winning type is won, any of the winning combinations shown in FIG. Corresponding symbol combinations are not displayed on the active line A, and medals are not paid out. However, as will be described later, when the BB internal winning flag is carried over to the next game, the symbol combination corresponding to the winning combination “BB” can be displayed on the active line A by winning the winning type “losing”. It becomes possible.

  In addition, the winning areas 2 to 26 are associated with one replay combination alone or with a plurality of replay combinations overlapped. And, when a winning category including a plurality of winning combinations is included, winning conditions regarding which symbol combination corresponding to which winning combination is preferentially displayed on the active line A, for example, stop The order in which the switches 120a, 120b, 120c are operated is set.

  In the following description, the operation of the stop switches 120a, 120b, and 120c for stopping the reels in the order of the left reel 110a, the middle reel 110b, and the right reel 110c is referred to as “batting order 1”, and the left reel 110a, the right reel 110c, and the middle reel 110b are operated. The operation of the stop switches 120a, 120b, 120c for stopping the reels in order is “batting order 2”, and the operation of the stop switches 120a, 120b, 120c for stopping the reels in the order of the middle reel 110b, the left reel 110a, and the right reel 110c is “batting order”. 3 ”, the operation of the stop switches 120a, 120b, and 120c for stopping the reels in the order of the middle reel 110b, the right reel 110c, and the left reel 110a is“ batting order 4 ”, and the right reel 110c, the left reel 110a, and the middle reel 110b in this order. Stop reel The operation of the stop switches 120a, 120b, 120c to be operated is “batting order 5”, and the operation of the stop switches 120a, 120b, 120c for stopping the reels in order of the right reel 110c, the middle reel 110b, and the left reel 110a is “batting order 6”. .

  For example, in the RT1 gaming state, when the winning type “Transition Replay 1” is won and an operation according to batting order 1 is performed, the symbol combination corresponding to the winning combination “Transition Replay 2” indicating the transition to the RT2 gaming state is effective. Stop control is performed so as to preferentially display on the line A. In addition, when an operation according to batting order 2 to batting order 6 is performed, the symbol combination corresponding to the winning combination “transition replay 3” and “transition replay 4” indicating the transition to the RT3 gaming state is preferentially placed on the active line A. Stop control is performed so as to be displayed.

  The winning areas 28 to 39 include the winning combination “Bell” and the winning combination “One piece combination”, including the winning types “batting order bell left 1” to “batting order bell right 4” (hereinafter referred to as 12 Each winning category is simply associated with a winning category “batting order bell”). Note that the winning probabilities (numbers of numbers) of the winning regions 28 to 39 are set to be equal. Since the player cannot normally know which winning type is won, providing the winning areas 28 to 39 as described above makes it difficult to win the winning combination “Bell”. In addition, even if the stop switches 120a, 120b, 120c are operated in the batting order in which the winning combination “one piece combination” is displayed preferentially, the symbol combination corresponding to the winning combination “one piece combination” is not necessarily on the active line A. Since it is not always displayed, depending on the operation mode, there is a case where overshooting occurs (PB ≠ 1). In addition, the winning areas “Bell 2” and “Bell 3” are included in the winning areas 40 to 42 in correspondence with winning types “batting order bell left middle” to “batting order bell middle right”, respectively. ing. The winning probabilities (numbers of numbers) of the winning areas 40 to 42 are set to be equal.

  In addition, the winning areas 50 to 53 are associated with winning types “RBB1”, “RBB2”, “RBB3”, and “RBB4” that include the winning combination “RBB1”. The winning types “RBB5”, “RBB6”, “RBB7”, and “RBB8” are associated with the winning combination “RBB2”, and the winning areas 58 to 61 include the winning combination “CBB1”. “CBB1”, “CBB2”, “CBB3”, “CBB4” are associated with each other, and the winning areas 62 to 65 include the winning combination “CBB2”, “CBB5”, “CBB6”, “CBB7”. ”And“ CBB8 ”are associated with each other. In the following, the winning types “RBB1”, “RBB2”, “RBB3”, “RBB4”, “RBB5”, “RBB6”, “RBB7”, “RBB8”, “CBB1”, “CBB2”, “CBB3” , “CBB4”, “CBB5”, “CBB6”, “CBB7”, and “CBB8” may be simply abbreviated as the winning type “BB”.

  If any of the above-mentioned winning types is won, internal winning flags corresponding to the respective winning types are established (turned on), and stop control of each reel 110 is performed according to the establishment status of the internal winning flag. The Rukoto. At this time, if the winning combination including the small combination is won, but the symbol combination corresponding to the winning combination cannot be displayed on the active line A in the game, after the end of the game The internal winning flag is turned off. In other words, the right to win a small role is limited to only the game won in the winning type including the small role, and the right cannot be carried over to the next game. On the other hand, when the winning type including the winning combination “BB” is won, the BB internal winning flag is established (turned on), and the symbol combination corresponding to the winning combination “BB” is on the active line A. Until it is displayed, the BB internal winning flag is carried over the game. In addition, when the internal winning flag corresponding to the winning type including the winning combination “Replay” that is the replaying role is established, the winning combination “Replay” of the winning combination “Replay” included in the winning type is established. The symbol combination corresponding to "" is always displayed on the active line A, and after the processing necessary for performing the next game without requiring a medal is performed, the internal winning flag is turned off.

(Game state transition)
Here, the transition of the gaming state including the bonus gaming state will be described with reference to FIG. Here, a plurality of gaming states such as an RT0 gaming state, an RT1 gaming state, an RT2 gaming state (which may be an ART gaming state described later), an RT3 gaming state, an RT4 gaming state, an internal medium gaming state, and a bonus gaming state are prepared. ing. In the RT0 gaming state, the RT1 gaming state, the RT2 gaming state, the RT3 gaming state, and the RT4 gaming state, the winning probabilities of the replay roles are set (RT0 gaming state = 1 / 7.3, RT1 gaming state = 1/1. 4, RT2 gaming state = 1 / 1.4, RT3 gaming state = 1 / 7.3, RT4 gaming state = 1 / 7.3), so-called RT gaming state, as will be described later, a predetermined winning combination Is displayed on the active line A, or the RT gaming state transitions in connection with the winning of the bonus combination. Here, the winning probability of the replay role in the RT1 gaming state and the RT2 gaming state is set to be relatively high, and the player can advance the game advantageously by shifting to the RT1 gaming state or the RT2 gaming state. .

  The RT0 gaming state in the normal gaming state is a gaming state corresponding to the initial state in a plurality of gaming states. In the RT0 gaming state, when the winning type “batting order bell” is won, and the combination of symbols corresponding to any small part (winning part “Bell”, “one piece part”) is not displayed on the active line A When the symbol combination corresponding to the displayed blank symbol combination is displayed on the activated line A, the gaming state control means 312 shifts the gaming state to the RT1 gaming state (1).

  Further, in the RT1 gaming state, when the winning combination “transition replay 1” to “transition replay 6” is won and the symbol combination corresponding to the winning combination “transition replay 2” is displayed, the gaming state The control means 312 shifts the gaming state to the RT2 gaming state (2). In such an RT2 gaming state, it is assumed that an AT is performed in parallel under a predetermined condition, that is, so-called AT is performed in parallel (AT rendering state), and in this embodiment, in parallel with the RT2 gaming state. The state in which AT is executed is referred to as ART gaming state.

  In the RT2 gaming state, when a winning combination “Transition Replay 13” to “Transition Replay 15” is won and a symbol combination corresponding to the winning combination “Transition Replay 1” is displayed, If the winning combination of type “batting order bell” is won and no symbol combination corresponding to any of the small roles (winning role “Bell” or “one-piece role”) is displayed on the active line A, that is, a blank symbol combination. When the corresponding symbol combination is displayed on the activated line A, the gaming state control means 312 shifts the gaming state to the RT1 gaming state (3).

  In the RT1 gaming state, the winning combination “Transition Replay 1” to “Transition Replay 12” is won, and the symbol combination corresponding to the winning combination “Transition Replay 3” or the winning combination “Transition Replay 4” is selected. When displayed, the gaming state control means 312 shifts the gaming state to the RT3 gaming state (4). In the RT0 gaming state, the winning combination “Transition Replay 7” to “Transition Replay 12” is won, and the symbol combination corresponding to the winning combination “Transition Replay 3” or the winning combination “Transition Replay 4” is selected. When displayed, the gaming state control means 312 shifts the gaming state to the RT3 gaming state (5). Further, the gaming state control means 312 shifts the gaming state to the RT0 gaming state when a predetermined number of games (for example, 16 games) have elapsed without winning the winning type “BB” in the RT3 gaming state (6). ).

  In addition, in the winning type lottery in the RT0 gaming state, the RT1 gaming state, the RT2 gaming state, the RT3 gaming state, or the RT4 gaming state, one of the winning types including the bonus combination is won, and the BB internal winning When the flag is established, the gaming state control means 312 shifts the gaming state to the internal middle gaming state corresponding to the bonus gaming state preparation state (7). At this time, if the symbol combination corresponding to the bonus combination cannot be displayed on the active line A, the BB internal winning flag is carried over to the next game as it is (the internal game state is maintained), and the next and subsequent times. In the game, the symbol combination corresponding to the bonus combination can be displayed on the active line A. In the internal gaming state, the winning probability of the replay role (for example, the winning type “normal replay 1”) is set higher (for example, 1 / 3.0) than the preceding (immediately preceding) gaming state. It is possible to aim to display the symbol combination corresponding to the bonus combination on the effective line A while suppressing. When the player displays the symbol combination corresponding to the bonus combination on the activated line A, the gaming state control means 312 shifts the gaming state from the internal middle gaming state to the bonus gaming state (8). In addition, in the bonus game state, when more than a predetermined number of medals associated with each bonus combination are paid out, the game state control means 312 is independent of the game state when the winning type including the bonus combination is determined. The gaming state is shifted from the bonus gaming state to the RT4 gaming state (9). Therefore, when a bonus combination is won, the RT4 gaming state is always passed before the transition from the RT0 gaming state to the RT3 gaming state.

  In the RT4 gaming state, the winning type “batting order bell” was won, and the combination of symbols corresponding to any small part (winning part “Bell”, “one piece part”) was not displayed on the active line A. In this case, the symbol combination corresponding to the blank symbol combination is displayed on the activated line A, and the gaming state control means 312 shifts the gaming state to the RT1 gaming state (10).

(Direction state transition)
FIG. 9 is an explanatory diagram for explaining the transition of the effect state on the main control board 200. Hereinafter, the effect state (non-AT effect state, AT effect state) transitioned by effect state control means 314 on main control board 200 will be described in detail.

(Non-AT production state)
The non-AT effect state includes a normal effect state and a chance effect state (chance zone). When the non-AT effect state is executed, the execution frequency of the auxiliary effect is much lower than that of the AT effect state, and the auxiliary effect is hardly performed, so the number of medals that can be acquired is limited. The normal performance state is a game state corresponding to an initial state among a plurality of performance states managed by the sub control board 202.

  The production state control means 314 shifts the game state to the chance production state at a predetermined opportunity in the normal production state (1), and when a predetermined condition is satisfied in the chance production state, for example, a predetermined number of games is consumed. Then, the normal performance state is restored (2). In addition, the production state control means 314 can shift the production state to the AT production state in the normal production state and the chance production state (3). However, the chance effect state is set so that it is easier to shift to the AT effect state than the normal effect state. For example, in any game state of the normal effect state and the chance effect state, it is determined by lottery (effect state lottery) whether or not to shift to the AT effect state based on the winning type determined by the winning type lottery. In addition, the probability of shifting to the AT effect state associated with each winning category is higher in the chance effect state than in the normal effect state. Therefore, the player desires to stay in the chance effect state rather than the normal effect state. Further, when the predetermined number of games is consumed in the non-AT effect state without shifting to the AT effect state (so-called ceiling arrival), the effect state control means 314 shifts the game state to the AT effect state.

(AT production state)
In the AT effect state, it is possible to acquire many medals while suppressing the consumption of medals by notifying the correct operation mode by the assist effect. Therefore, the player can advantageously advance the game in the AT effect state compared to the non-AT effect state.

  In the AT effect state, two AT effect states, a normal AT effect state and a chance AT effect state (specialized zone), are provided. In the normal AT effect state, a predetermined number of continuous games (for example, 50 games) is set as one set, and the game progresses by managing the number of sets. When the production state is set to the normal AT production state, the production state control means 314 subtracts 1 from the number of stocks (held) and sets the number of continuous games to 50 games. Then, when the game of the number of continuous games is finished, the production state control means 314 determines whether the number of sets is 0 (whether the number of sets is stocked). Subtract 1 from the number of sets to continue the normal AT effect state (4). However, the number of continuous games when the normal AT effect state is continued is a predetermined number of games of 30 games or more. On the other hand, when the number of stocked sets is 0, the effect state control means 314 ends the normal AT effect state and shifts the effect state to the chance effect state (5). Moreover, the production | presentation state control means 314 can transfer a production | presentation state to a chance AT production state, if predetermined conditions are satisfy | filled in a normal AT production | presentation state (6).

  The chance AT effect state continues until a predetermined number of games elapses, during which the number of sets in the normal AT effect state is added. When the predetermined number of games is over, the effect state control means 314 shifts the effect state to the normal AT effect state (7).

  In both the gaming state and the production state, when the winning or overtaking of a predetermined winning combination is used as the transition condition, the preparation state until the transition condition is satisfied (for example, from the non-AT production state to the normal AT production) There is a case where the state (3), the normal AT effect state, the chance effect state (5)), the game state or effect state of the transition destination may be transferred.

(About advantageous sections)
By the way, if the frequency of transition to the bonus game state or the AT effect state as described above is biased, there is a concern that the shooting performance may be excessively increased. Therefore, in order to comprehensively and uniformly determine whether or not the gaming state with high medal acquisition performance is biased, determination criteria such as an advantageous section ratio, a continuous combination ratio, and a combination ratio are provided. The advantageous section ratio is obtained by dividing the number of staying games, which is the number of games staying in the advantageous section, by the total number of games, which is the total number of games since the slot machine 100 was installed in the game hall (hall), % (Percent), and the consecutive character ratio is the number of medals paid out by the payout control means 310 due to the operation of the first type special character such as a regular bonus game in a predetermined reference counting period. Divide the number of consecutive feature payouts by the total payout number that is the total number of medals paid out by the payout control means 310, and a value expressed as a percentage. The number of rewards paid out, which is the number of medals paid out by the payout control means 310 based on the operation of the money, is divided by the total payout number, which is the total number of medals paid out by the payout control means 310, and is expressed as a percentage. is there. Note that the advantageous section ratio uses only the total number of games, and does not use a finite number of games such as 6000 games, such as the consecutive character ratio and the character ratio.

  Here, the advantageous section refers to a section advantageous for the player, including a section having performance related to the instruction function, that is, a section in which an auxiliary effect (instruction function) is executed. In addition, states belonging to such advantageous sections are collectively referred to as advantageous states, and states not belonging to the advantageous sections (belonging to non-advantageous sections that are not advantageous sections) are collectively referred to as non-advantageous states. The normal AT effect state and the chance AT effect state described above are included in the advantageous state in that the auxiliary effect that can obtain the maximum payout number is executed at least once, and during such an advantageous state (in the advantageous zone). The bonus game state to be executed and the internal middle game state are also included in the advantageous state. Therefore, the advantageous section ratio is a game in the AT effect state and the chance effect state, and the inside middle game state and the bonus game state in such an advantageous section for all the numbers of games in the AT effect state and the non-AT effect state. It represents the ratio of staying games.

  The bonus is a device for facilitating winning, and includes a regular bonus (RB), a challenge bonus (CB), a single bonus (SB), and the like. Moreover, a regular bonus (RB) respond | corresponds to a 1st type special actor among such actors. The regular big bonus (RBB) is a regular bonus (RB) that operates continuously regardless of the display of the symbol combination indicating the winning pattern of the regular bonus (RB), which is the first type special bonus, The Challenge Big Bonus (CBB) is a series of Challenge Bonuses (CB) regardless of the symbol combination indicating the type of winning of the Challenge Bonus (CB), which is the second type special character (one of the characters). It works with. Therefore, the continuous feature ratio represents the ratio of the number of consecutive feature payouts paid out by the operation of the first type special feature to the total number of payouts paid out during the predetermined standard aggregation period. Represents the ratio of the number of paid-out items by the operation of the bonuses to the total number of paid-outs in the predetermined reference tabulation period.

  The reference tabulation period is a target period in which the number of medals paid out by the payout control unit 310 is accumulated. In the present embodiment, for example, there are two types of 6000 games, which are finite values, and all periods (hereinafter referred to as “total cumulative”) after the slot machine 100 is installed in the game hall (hall). Here, as the 6000 games, the latest 6000 games starting from the current game are targeted, but as will be described later, the calculation is performed every predetermined number of games (for example, 400 games). Therefore, as the continuous character ratio, the 6,000 game continuous character ratio and the total cumulative character ratio are derived, and as the character ratio, the 6000 game character ratio and the total cumulative character ratio are calculated. To derive. However, it goes without saying that an arbitrary number of games can be set as the reference tabulation period.

  In order to obtain such an advantageous section ratio, continuous accessory ratio, and accessory ratio, the production state control means 314 calculates the total number of games, the number of stay games, the total number of payouts, the number of consecutive feature payouts, and the number of feature payouts. Accumulate. At this time, a counter is associated with each of the total number of games, the number of staying games, the total number of payouts, the number of consecutive winnings, and the number of winnings. Specifically, when one game is started, the effect state control means 314 increments a total game number counter indicating the total number of games by one. Then, it is determined whether or not the current performance state is an advantageous state, and if it is the advantageous state, a stay game number counter indicating the number of stay games is incremented by one. The stay game number counter is updated from the next game of the game won in the advantageous state (the game in which the process of shifting to the advantageous section has been performed) when the effect state is the non-advantageous state. However, when the transition to the AT effect state is determined based on the winning of the regular big bonus (RBB) or the challenge big bonus (CBB), the game is started from the game next to the game in which the bonus is won.

  In addition, when the medal is paid out in the game, the production state control means 314 increments the total payout number counter indicating the total payout number by the payout number. If the payout of the medal is based on an accessory, the accessory payout counter indicating the number of payout of the accessory is incremented by the number of payouts, and the payout of the medal is changed to the first type special accessory. If it is based, in addition to the accessory payout number counter, a continuous feature payout number counter indicating the number of consecutive feature payouts is incremented by the number of payouts. The counting by such a counter is always executed regardless of the specified number or set value. In this way, the total number of games, the number of stay games, the total number of payouts, the number of consecutive feature payouts, and the number of payouts of items are accumulated.

  Subsequently, the production state control means 314 calculates the advantageous section ratio, the continuous character ratio, the character ratio based on the accumulated total game number, stay game number, total payout number, continuous feature payout number, and feature payout number. Is derived. Specifically, the production state control means 314 divides the number of staying games by the total number of games, converts it into%, derives an advantageous section ratio, and, for each predetermined number of games (for example, 400 games), Divide the total number of payouts by the total cumulative number of payouts, convert it to% to derive the total cumulative continuous feature ratio, divide the total cumulative number of payouts by the total cumulative total number of payouts, and convert to% Deriving the total cumulative ratio of properties. In addition, for each predetermined number of games (for example, 400 games), the production state control unit 314 divides the number of consecutive winnings for the past 6000 games by the total number of paying for 6000 games, and converts it into% to convert the number of consecutive roles for 6000 games. The physical ratio is derived, and the number of paid-out items in the past 6000 games is divided by the total number of paid-out 6000 games, and converted into% to derive the functional rate of 6000 games.

  As described above, in the present embodiment, as the advantageous section ratio, the continuous accessory ratio, and the accessory ratio, values finally converted to% are obtained. This indicates that only two digits after the decimal point are necessary for the result of division. In this embodiment, the value after the decimal point when converted to% is rounded down. This means that if only 2 digits after the decimal point can be derived from the division result, an operation after 3 digits after the decimal point is not required. Next, the production state control means 314, based on a predetermined display command, derives the derived advantageous section ratio, the 6000 game continuous feature ratio, the 6000 game feature ratio, the total cumulative feature ratio, and the total cumulative ratio. The accessory ratio is displayed on a ratio display unit (not shown) provided on the main control board 200, for example, which is visible to the administrator. In this way, the manager can visually recognize the advantageous section ratio, the continuous accessory ratio, and the accessory ratio together with the identifiers.

  Hereinafter, specific processing in the main control board 200 and the sub control board 202 will be described based on flowcharts.

(Main processing of main control board 200)
FIG. 10 is a flowchart showing main processing of the main control board 200. Here, first, an outline of one game after initialization will be described along the main process of the main control board 200, and then the details of each process will be described. Here, processing related to the features of the present embodiment will be described in detail, and descriptions of configurations unrelated to the features of the present embodiment will be omitted. Although detailed description is omitted, when each process is performed, the switches (the bet switch 116, the start switch 118, and the stop switches 120a, 120b, and 120c) used in each process are enabled at the start of the process. Invalidated at the end of processing.

(Step S100)
When the power of the slot machine 100 is turned on via the power switch 144 and becomes energized, the initialization unit 300 executes an initialization process in preparation for the start of the game. The initialization unit 300 generates backup data at any time while the power is on, and holds the backup data in the main RAM 200c. Therefore, even if an unexpected power interruption occurs, it is possible to restore the state before the power interruption using the stored backup data in this initialization process. For example, even if an unexpected power interruption occurs during the rotation of the reel 110, the operation is started from the state where each reel 110 is rotated again after the return operation. Therefore, in the initialization process, the main RAM 200c is basically not initialized (RAM clear).

(Step S200)
Subsequently, the betting means 302 bets medals through the operation of the bet switch 116 by the player or the insertion of medals into the medal insertion unit 114. Further, the command transmission unit 316 generates an input command indicating that the operation has been performed, and transmits the generated input command to the sub control board 202.

(Step S300)
Next, the winning type lottery means 304 validates the game start operation with respect to the start switch 118 and shifts to a state of waiting for the operation of the start switch 118. Here, the winning type lottery means 304 at the time when the start switch 118 is operated from the winning type lottery random number updated by the random number generator 200d of the main control board 200 according to the operation of the start switch 118 by the player. 1 winning type lottery random number is acquired. Then, the winning type lottery means 304 determines one winning type lottery table corresponding to the currently set gaming state from the winning type lottery table shown in FIGS. 6 and 7, and the acquired winning type lottery random number. However, it is determined which winning area corresponds to the determined winning type lottery table, and the winning type or the unfavorable winning of the determined winning area is determined as the lottery result.

  In addition, after the lottery result is determined in accordance with the operation of the start switch 118, the command transmission unit 316 generates a winning type command including a lottery result (winning type or unsuccessful winning) of the winning type lottery, information on the gaming state, and the like. Then, the generated winning type command is transmitted to the sub control board 202.

(Step S400)
When the start switch 118 is operated, the reel control unit 306 drives the stepping motor 152 to rotate the left reel 110a, the middle reel 110b, and the right reel 110c. In this reel rotation process, when a predetermined time (for example, 4.1 seconds) elapses from the start of rotation of the left reel 110a, middle reel 110b, and right reel 110c in the previous game (wait), the left reel in the game The rotation of 110a, middle reel 110b, and right reel 110c is started, and when all of the left reel 110a, middle reel 110b, and right reel 110c are rotated at a constant speed, the process proceeds to step S500.

(Step S500)
Subsequently, when the reel control means 306 activates the stop switches 120a, 120b, and 120c and accepts an operation of the stop switches 120a, 120b, and 120c by the player, the left reel 110a, the middle reel 110b, and the right corresponding to the operation are received. One of the reels 110c is controlled to stop.

  In addition, when any one of the stop switches 120a, 120b, and 120c is operated, the command transmission unit 316 displays a stop command (a first stop command, a second command) indicating information on the operated stop switches 120a, 120b, and 120c. A stop command and a third stop command) are generated for each operation, and the generated stop commands are sequentially transmitted to the sub-control board 202.

(Step S600)
Next, the determination means 308 determines which combination the symbol combination displayed on the active line A shown in FIG. 3B corresponds to and determines the gaming state according to the symbol combination. Various processes required for change and replay are executed. Further, the command transmission means 316 generates a winning command including a symbol combination displayed on the effective line A and a medal payout number when the symbol combination corresponding to the small role is displayed on the effective line A. The generated winning command is transmitted to the sub-control board 202.

(Step S700)
Subsequently, when the symbol combination corresponding to the small combination is displayed on the active line A based on the determination result in step S600, for example, the payout control unit 310 executes a medal payout process corresponding to the small combination. When the symbol combination corresponding to the replay combination is displayed on the active line A, a process for automatically betting the next game is executed. The gaming state control means 312 shifts the gaming state from the bonus gaming state to the RT4 gaming state when a predetermined number of medals are paid out in the bonus gaming state. Thus, the payout control means 310 performs various processes corresponding to the symbol combination displayed on the active line A, and ends the one game. In addition, when the medal payout process is performed, the command transmission unit 316 generates a payout command indicating that the payout process has been performed, and transmits the generated payout command to the sub-control board 202.

  One game is executed through a series of processes from step S200 to step S700. Thereafter, steps S200 to S700 are repeated.

(Memory management by main CPU 200a)
Incidentally, as described above, in the main control board 200, the main CPU 200a cooperates with the main RAM 200c based on the program stored in the main ROM 200b, whereby the initialization means 300, the betting means 302, and the winning type lottery means 304. , Reel control means 306, determination means 308, payout control means 310, game state control means 312, effect state control means 314, command transmission means 316, etc., and controls the progress of the game. Programs for executing these functional units are arranged in predetermined areas (usage areas) of the main ROM 200b and the main RAM 200c.

  FIG. 11 is an explanatory diagram showing a memory map of the main ROM 200b and the main RAM 200c. Here, the main ROM 200b is allocated to the memory space of 0000h to 2FFFh (12 kbytes), and the main RAM 200c is allocated to the memory spaces of F000h to F1FFh (512 bytes) and F200h to F3FFh (512 bytes). The use area is defined in both the main ROM 200b and the main RAM 200c.

  A use area is allocated to the memory space of 0000h to 1DF3h in the main ROM 200b. Specifically, in a memory space limited to 0000h to 11FFh (4.5 kbytes), initialization means 300, betting means 302, winning type lottery means 304, reel control means 306, determination means 308, payout control means 310, game Stores the instruction code (the instruction code may be referred to as a module) of a program for executing the game control process for controlling the progress of the game by causing the state control means 312, the effect state control means 314, and the command transmission means 316 to function. In a memory space limited to 1200h to 1DF3h (3.0 kbytes), data used for the game control processing program is stored. A comment area is assigned to the memory space 1E00h to 1EFFh, and a program management area is assigned to the memory space 2FC0h to 2FFFFh. In addition, “h” added to the end of the numerical value indicates that the numerical value is a hexadecimal number. The instruction code of the program is written in assembler language. Here, the program is composed of instruction codes, and can be read out by a computer to realize predetermined processing in cooperation with data and a work area.

  Use areas are allocated to the memory spaces F000h to F1FFh of the main RAM 200c. Specifically, a work area for the game control process is assigned to the memory space F000h to F13Fh, and is used for managing variables such as timers, counters, and flags. The game control process stack area is allocated to the memory spaces F1C0h to F1FFh. The main CPU 200a is provided with an internal register.

  FIG. 12 is an explanatory diagram for explaining an internal register of the main CPU 200a. Each of the internal registers is configured by 8 bits or 16 bits, and may be used alone or in a predetermined combination (pair register). The internal registers include a front register and a back register corresponding to a part of the front registers.

  Of the internal registers shown in FIG. 12, the Q register (queue register) is an 8-bit dedicated register of an extended specification for gaming machines. The upper 1 byte of the Q register is fixed to F0h and used for accessing the main RAM 200c from F000h to F0FFh. The I register is a dedicated register for storing the upper 8 bits of the interrupt destination address. The A register is an 8-bit accumulator used for arithmetic processing and data transfer. The F register is an 8-bit flag register that holds various calculation results. Here, as shown in FIG. 12, each bit of the F register is from the most significant bit (MSB: Most Significant Bit) to the least significant bit (LSB), and s is 1 when the operation result is negative. Z is a zero flag that is set to 1 when all bits are 0 as a result of the operation, and tz is all bits that are 0 by execution of a data transfer instruction (LD; load). At this time, it is a specific bit flag (second zero flag) of the extended specification for gaming machines that is set to 1 (the value changes), and may be referred to as a sett flag. h is a half-carry flag that cannot be involved by a programmer, * is a reserved bit (undefined), p / v is a parity overflow flag, n is an addition / subtraction flag that cannot be involved by a programmer, and c is This is a carry flag that is set to 1 when a carry or borrow occurs as a result of the operation. Note that the F register constitutes an A register and a pair register AF.

  The B register, C register, D register, E register, H register, and L register are 8-bit general-purpose registers, and constitute a 16-bit pair register BC, DE, and HL, respectively. The IX and IY registers are 16-bit dedicated registers for index addressing, IXh and IYh indicate the upper 8 bits, and IXl and IYl indicate the lower 8 bits. A 'register, F' register, B 'register, C' register, D 'register, E' register, H 'register, L' register are A register, F register, B register, C register, D register, E register , H register and L register are back registers that can exchange data (contents) by an exchange command with the front register, and A ′ register and F ′ register constitute pair register AF ′, and B ′ register and C ′ register The pair register BC ′ is configured, the pair register DE ′ is configured by the D ′ register and the E ′ register, and the pair register HL ′ is configured by the H ′ register and the L ′ register. Such a back register functions as a stack area for the front register when an interrupt process occurs.

  Under such an environment, the main CPU 200a refers to the program data of the use area according to the instruction code of the use area program in accordance with, for example, an interrupt signal every 1.49 msec, Using the work area and the stack area of the used area, the initialization means 300, the betting means 302, the winning type lottery means 304, the reel control means 306, the determination means 308, the payout control means 310, the game state control means 312 and the effect state A game control process for causing the control means 314 and the command transmission means 316 to function is performed.

  FIG. 13 is an explanatory diagram showing an instruction code of a program arranged in the control area of the use area. Here, the main CPU 200a, for example, in accordance with an interrupt signal every 1.49 msec, uses the instruction code of the program (use program) stored in the use area shown in FIGS. 13 (a) and 13 (b). Perform control processing. The internal register does not include the stack pointer SP and the program counter PC. Further, the contents of the R register (refresh register) are excluded from the processing because they do not need to be protected.

  When the instruction code of the program of FIG. 13A is executed in the use area, first, an interrupt is prohibited by an interrupt disable instruction “DI”. Next, a zero flag is set according to the value of the A register by the logical instruction “OR A”. For example, if the value of the A register is 0, the zero flag is set to 1, and if the value of the A register is not 0, the zero flag is set to 0.

  Subsequently, it is determined by the jump instruction “JP Z, MAIN1” whether or not the zero flag is 1. If the zero flag is 1, the program jumps to the instruction code of the program “MAIN1” stored in the same use area. . Then, the game control process is performed according to the instruction code of the program shown in FIG. When this process is completed, the process returns to the original instruction code by the jump instruction “JP MAIN2”. Finally, the interrupt is permitted by the interrupt permission instruction “EI”. If the zero flag is 0 when the jump instruction “JP Z, MAIN1” is executed, the instruction code of the program shown in FIG. 13B is not executed and the interrupt enable instruction “EI” Is allowed.

  Here, the game control process is performed using only the use area and without moving the process to another area. In this way, in the game control process, a plurality of instruction codes (modules) are stored in the use area, and one of them is called from a plurality of instruction codes, or a plurality of instruction codes are obtained by one interrupt. May be executed.

  In addition to the game control process described above, the slot machine 100 performs a game machine test process, a security related process, an advantageous section related process, etc., which are processes that do not affect the progress of the game at a predetermined opportunity. There is a case. As such a predetermined opportunity, a timing according to an interrupt of the game control process (for example, at the end of one game) or a timing according to a different interrupt independent of the game control process can be employed. Hereinafter, processing modes of gaming machine test processing, security related processing, and advantageous section related processing will be described.

(Test processing for gaming machines)
The main CPU 200a refers to the program data required for the connection of the gaming machine test machine according to the instruction code of the program required for the connection of the gaming machine testing machine, and each internal register, work area and stack area. Perform gaming machine test processing using The contents are described in the connection specifications (fourth edition) of the test machine for the swivel type gaming machine. The outline will be described below.

  FIG. 14 is an explanatory diagram for explaining a test firing test of the slot machine 100. In the trial test, as shown in FIG. 14, the slot machine 100 and the trial test machine 400 are connected via a first interface board 402 and a second interface board 404 for unifying each signal.

  First, the test test machine 400 outputs a predetermined signal to the slot machine 100 via the connect CN 3 of the first interface board 402. The predetermined signal output here is, for example, a pseudo signal indicating that the bet switch 116, the start switch 118, the stop switch 120, and the like are operated. Actually, since these switches are not operated, a sensor provided for each switch does not output a detection signal, but a pseudo signal is output as if it was operated in a pseudo manner.

  In response to the signal, the main control board 200 outputs a predetermined signal to the test fire testing machine 400 via the connections CN1 and CN2 of the first interface board 402. The predetermined signal output here is a signal indicating the state of the effect lamp 126, the state of various sensors, the position of the stepping motor 152, and the like. When an auxiliary effect based on the AT effect state or the like is employed, the main control board 200 outputs a predetermined signal to the test firing test machine 400 via the connect CN 4 of the second interface board 404. The predetermined signal output here is a signal or the like related to a gaming method capable of obtaining the maximum payout rate. Here, such a signal is mainly represented by a discrete signal, that is, a binary value of 1 (HIGH) or 0 (LOW).

  And, assuming the configuration as shown in FIG. 14, whether the operation status of the game control processing (winning type lottery, reel control, bet, etc.) for the inputs of the start switch 118, stop switch 120, bet switch 116, etc. is normal, It is tested whether the main credit display unit 130, the main payout display unit 132, various lamps are normally displayed, and the like. Further, various timings of operation of the bet switch 116, the start switch 118, the stop switch 120, and the game control process, for example, after the start switch 118 is operated, the stop switch 120 is first activated, and the corresponding effect lamp Whether the signal has changed since the signal ON / OFF condition, such as the timing at which the lamp signal managing the lighting / extinguishing state of 126 is turned on, or is the timing included in the appropriate time range? Are tested.

  In addition, as a test relating to the performance of the ball (confirming the upper and lower limits of the ball appearance rate), for example, (1) the short time ball output rate (the ball output rate in an arbitrary 400 game section is less than 300%) ), (2) Medium-time play rate (the play rate in any 6000 game section is less than 150%), (3) Long-time play rate (the play rate in any 17500 game section is (It must be less than 120% and must exceed 55%). (4) Character ratio (obtained by the action of the bonus characters (SB, CB, MB, RB, BB) among game medals paid out from the slot machine 100) (5) Consecutive character ratio (out of game medals paid out from gaming machines, 60% of the contests earned by operating the continuous character (RB or BB)) And the like). The test methods include (A) simulation test (test to acquire the maximum number that can be acquired in each game), (B) test fire test 1 (test to play in the same game method as the game method that the player plays) ), (C) test firing test 2 (a game method with a minimum play rate).

(Security-related processing)
In addition, the main CPU 200a refers to the program data necessary for specifying the abnormal state according to the instruction code of the program necessary for specifying the abnormal state for the purpose of preventing fraud by a third party, and Security related processing is performed using each internal register, work area and stack area.

  FIG. 15 is an explanatory diagram for explaining an abnormal state. In this embodiment, as shown in FIG. 15, for example, 12 (type) abnormal states “backflow error”, “empty error”, “payout clog error”, “payout error” managed by the main control board 200 ”,“ Over error ”,“ Stalling error ”,“ Backup error ”,“ Door open error ”,“ Insertion error ”,“ Display determination error ”,“ RWM error ”,“ Setting value error ” Error codes “E1”, “E2”, “E3”, “E4”, “E5”, “E6”, “E7”, “E8”, “E9”, “EE”, “EA”, respectively. , “EC”.

  Such abnormal states are respectively defined as follows. For example, the abnormal state “backflow error” occurs when the insertion order of medals is not correct in the two passing sensors of the inserted medal detection unit 114b in a state where the insertion of medals is accepted. The abnormal state “empty error” occurs when a medal is paid out when an OFF state of a passing sensor of a payout medal detection unit (not shown) constituting the medal payout device 142 continues for a predetermined time (for example, 2100 msec). . The abnormal state “payout clogging error” occurs when the passing sensor of the payout medal detection unit has been on for more than a predetermined time (for example, 172 msec) when paying out medals. The abnormal state “payout abnormality error” occurs when the passage sensor ON state of the payout medal detection unit continues for a predetermined time (for example, 6 msec) other than the medal payout. The abnormal state “over error” is generated when an ON state of an overflow sensor (not shown) provided in a medal storage unit (not shown) constituting the medal payout device 142 continues for a predetermined time (for example, 700 msec) or more. . The abnormal state “stay error” indicates that the ON sensor of the inserted medal detection unit 114b has been turned ON for a predetermined time (for example, 132 msec) or the ON detection sensor that detects a medal inserted into the medal slot 114a is ON. This occurs when the state continues for a predetermined time (for example, 533 msec) or longer. The abnormal state “backup error” occurs when an RWM backup abnormality is detected when the power switch 144 is turned on. The abnormal state “door open error” indicates that the ON state of a door opening / closing switch (not shown) that detects the open state of either the front upper door 104 or the front lower door 106 as the front door is longer than a predetermined time (eg, 48 msec). Occurs when continued. The abnormal state “insertion error” is when the passage sensor of the inserted medal detection unit 114b is in an ON state after a predetermined time (for example, 269 msec) has elapsed since the blocker (not shown) is closed, or the insertion of a medal is accepted. This occurs when the difference between the number of medals passed in the correct order in the two passing sensors of the inserted medal detecting unit 114b and the number of medals passing through the R-chute sensor (not shown) is greater than or equal to a certain level. In the abnormal state “display determination abnormal error”, in the determination processing step S600, a winning combination of a small role that is not permitted to be displayed on the active line A, or a combination of symbols related to the operation of the replay role or bonus role is displayed. Occurs when displayed on the active line A. The abnormal state “RWM abnormal error” occurs when a RWM that cannot normally read and write a value is detected during a cold start. The abnormal state “setting value abnormality error” occurs when the referenced setting value is outside the allowable range (setting 1 to setting 6) at the time of internal lottery such as winning type lottery.

  The main CPU 200a determines whether or not any of the plurality of abnormal states has occurred, and the main credit display unit 130 or the main payout display unit 132 displays an error associated with the abnormal state. Display (notify) the code. Specifically, when the front upper door 104 or the front lower door 106 is opened, it is determined that an abnormal state “door opening error” has occurred, and an error code “E8” associated with the abnormal state “door opening error” is detected. Is displayed (notified) on the main payout display unit 132, for example.

(Advantageous section related processing)
In addition, the main CPU 200a calculates the advantageous section ratio, the continuous accessory ratio, and the accessory ratio in accordance with the instruction code of the program necessary for calculating the advantageous section ratio, the consecutive accessory ratio, and the accessory ratio described above. Referring to the program data required for the process, the advantageous section related processing is performed using each internal register, work area and stack area. For example, the main CPU 200a uses the work area to configure a total game number counter, a stay game number counter, a total payout number counter, an accessory payout number counter, and a continuous feature payout counter, and the progress of games and the payout of medals. The value is updated according to. Then, based on a predetermined display command, the production state control means 314 determines the derived advantageous section ratio, the 6000 game continuous character ratio, the 6000 game character ratio, the total cumulative consecutive character ratio, and the total cumulative character role. The object ratio is displayed on a ratio display unit (not shown) provided on the main control board 200.

  It should be noted that this advantageous section related process may be executed at the timing according to the interruption of the game control process, for example, during the execution of the payout process S700 at the end of one game, and a different interrupt independent of the game control process. It can also be performed at a timing according to Here, when the advantage section related processing is performed at the end of one game, the total number of games, the number of staying games, the total number of payouts, the number of consecutive feature payouts, the number of feature payouts, and the advantage section ratio are always calculated for each game. In addition, the 6000 game consecutive character ratio, the 6000 game character ratio, the total cumulative consecutive character ratio, and the total cumulative character ratio are calculated for each predetermined number of games (for example, 400 games).

(Another area different from the used area)
As described above, the main CPU 200a may perform not only gaming control processing but also gaming machine test processing, security related processing, and advantageous section related processing. However, the storage capacity of the use area is determined in advance. For example, as shown in FIG. 11, the control area is limited to 4.5 kbytes, and the data area is limited to 3.0 kbytes. Accordingly, if not only the game control process but also the programs and data for the gaming machine test process, the security related process, and the advantageous section related process are arranged in the use area, the game control process is limited accordingly. In particular, when the main CPU 200a manages the AT effect state or the so-called reel effect that rotates the reel 110 in various modes, the game control process may be further pressed.

  Here, the program (use program) and data for executing the game control process must be stored in the use area, but it does not affect the progress of the game other than the game control process (not directly related). Programs (separate programs) and data for executing the processes (game machine test process, security related process, advantageous section related process, etc.) can be stored in either the use area or the separate area. Therefore, in this embodiment, at least a part of a program or data for executing a gaming machine test process, a security-related process, an advantageous section-related process, etc. is stored in a storage area (outside the use area) different from the use area. Describe in a separate area that is part of it. As described above with reference to FIG. 11, the use area is allocated to the memory space of 0000h to 1DF3h of the main ROM 200b, and the use area is allocated to the memory space of F000h to F1FFh of the main RAM 200c. Then, another area is set in a different area from the use area.

  For example, as shown in FIG. 11, another area is allocated to the memory space of 1F00h to 2FBFh of the main ROM 200b, and some or all of the gaming machine test process, security related process, and advantageous section related process are performed. The instruction code and program data of the program to be stored are stored. Further, another area is allocated to the memory space of F200h to F3FFh of the main RAM 200c. Specifically, work areas for some or all of the gaming machine test processing, security-related processing, and advantageous section-related processing are allocated to the memory space of F210h to F22Fh, such as timers, counters, flags, and the like. Used for variable management. In the memory space of F230h to F246h, a stack area of a part or all of the gaming machine test process, the security related process, and the advantageous section related process is allocated. Note that there is no limit on the storage capacity in another area, and in the example of FIG. 11, it can be freely assigned to a storage area other than the use area, the comment area, and the program management area.

  As described above, processing performed in the usage area (here, game control processing) and processing that does not necessarily have to be performed in the usage area (here, gaming machine test processing, security related processing, advantageous section related processing). If they are mixed, the program (use program) and data for executing the game control process are stored in the use area, and the progress of the game other than the game control process may not be performed in the use area. A program (separate program) and data for executing non-existing processes (game machine test process, security related process, advantageous section related process, etc.) are stored in another area. For example, regarding the gaming machine test processing, the program and data required for connecting the gaming machine testing machine are the gaming machine rules, that is, the National Public Safety Commission on January 30, 2004 (2004). Schedule 3 (2) A (C) of the National Public Safety Commission Regulations No. 4 “Rules on the Authorization of the Pachislot Machines and Type Approval” on February 12, 1985, after the revision in Regulation No. 1 It is said that there is no problem in arranging it in an area different from the use area. By dividing the storage area into a plurality of areas as described above, there is a margin in the storage area of the use area by the amount of the program moved to another area. Therefore, it is possible to allocate the use area to the game control process (use program) accordingly.

  However, the fairness of the slot machine 100 must be ensured even when the storage area is divided among the use area, another area, and other areas. Here, the following conditions (1) to (6) are defined in order to appropriately share the roles between the use area and another area while ensuring the fairness of the slot machine 100.

  Condition (1): For programs to be placed in different areas, output of signals necessary for testing the slot machine 100 (testing process for gaming machines), fraud prevention (security related processes), and calculations related to valid sections (favorable sections) It is used for the purpose of related processing) and does not harm (do not impair) the fairness of the game. Regarding the condition (2), the control area and the data area that are different from the use area, they should be arranged in areas that are explicitly distinguished from each other. Condition (3), a program (separate program) to be placed in another area must be called statically from a program in the use area (use program) and executed. Also, in the program list at that time, the callee address must be clearly described. Condition (4), programs to be placed in separate areas should be modularized for each function, and when called, the contents of all registers used in the used area should be protected. Condition (5): Access to RWMs in each other area from the use area or another area can only be referred to, and cannot be updated. Condition (6): It is prohibited to call a subroutine in the control area of the use area from the control area of another area. Since a subroutine for performing an interrupt process is provided in the use area, it is necessary to disable the interrupt when using a control area of another area. In order to properly execute the game control process, the time from the prohibition of the interrupt to the release of the prohibition of the interrupt must be within an interval of the interrupt process in the game control process (eg, 1.49 msec). I must. Therefore, when calling a subroutine that uses a control area of another area, the total time required for one call is set to be within the interval of the interrupt process of the game control process. In the following, an example will be described in which a program arranged in another area is called from the use area after these conditions are defined.

(First embodiment)
FIG. 16 is an explanatory diagram showing instruction codes of programs arranged in the control area of the use area and the control area of another area. Here, the main CPU 200a performs a game control process according to an instruction code of a program (use program) stored in the use area shown in FIG. 16A, for example, in response to an interrupt signal every 1.49 msec. If necessary, a process for calling a program (separate program) in another area is performed. Then, the main CPU 200a performs processing by the instruction code of the program “SAMPLE1” stored in another area shown in FIG. 16B, and returns to processing of the program stored in the use area when the processing is completed. To do. Here, the program “SAMPLE1” indicates a typical example of the program called in the first embodiment, and actually, a plurality of programs (instruction codes) are stored in different areas as “SAMPLE1”. In the first embodiment, and in the second and third embodiments described later, an external interrupt and an unmaskable interrupt NMI are not used. The internal register does not include the stack pointer SP and the program counter PC. Further, the contents of the R register (refresh register) are excluded from the processing because they do not need to be protected.

  When the instruction code of the program of FIG. 16A is executed in the use area, first, an interrupt is prohibited by the interrupt disable instruction “DI”. Next, the contents of the internal registers (Q, I, AF, BC, DE, HL, IX, and IY) of the main CPU 200a used in the use area are collectively displayed by the save instruction “PUSH ALL”. Saved to the stack area of the used area. Thus, as shown in FIG. 16C, the contents of the internal register are held in the stack area (for example, addresses F1F2h to F1FFh) of the use area.

  Subsequently, the contents of the front register AF and the contents of the back register AF ′ are exchanged by the exchange instruction “EX AF, AF ′”, and the contents of the front registers BC, DE, HL are exchanged by the exchange instruction “EXX”. The contents of the registers BC ′, DE ′, and HL ′ are exchanged. Then, by the save instruction “PUSH GRP”, the contents of the internal registers (AF, BC, DE, and HL registers) (the original registers AF ′, BC ′, DE ′, HL ′) is saved in the stack area of the use area. The address of the stack area to be saved is a younger address so as not to overwrite the contents saved by the save instruction “PUSH ALL”. Here, as a result, the contents of the original back registers AF ′, BC ′, DE ′, and HL ′ are saved. In this way, as shown in FIG. 16C, the contents of the internal register are held in the stack area (for example, addresses F1EAh to F1F1h) of the use area. Here, since the contents of the original back registers AF ′, BC ′, DE ′, and HL ′ are also saved, the interrupt processing is temporarily executed in the use area, and the contents of the table registers AF, BC, DE, and HL are changed. Even if the program in the different area is executed in a state where it is saved in the back registers AF ′, BC ′, DE ′, HL ′, it is saved in the back registers AF ′, BC ′, DE ′, HL ′. The contents of the original table registers AF, BC, DE, and HL can be restored appropriately, and it is possible to reliably avoid the influence of the game control process in the used area.

  Thus, the contents of the internal registers (Q, I, AF, BC, DE, HL, IX, IY, AF ′, BC ′, DE ′, and HL ′ internal registers) of the main CPU 200a used in the use area are When all are saved, the main CPU 200a calls an instruction code of a program in another area shown in FIG. 16B by a call instruction “CALL SAMPLE1”. At this time, as shown in FIG. 16C, in the stack area of the used area (for example, addresses F1E8h to F1E9h), the return address of the calling instruction (F8E9h is the upper 8 bits of the return address, and F1E8h is the lower address of the return address. 8 bits) is saved.

  In another area, a predetermined process is executed according to the instruction code of the program shown in FIG. For example, some or all of the above-described gaming machine test processing, security-related processing, and advantageous section-related processing are performed. For example, in the payout process S700 in the game control process, the advantageous section related process stored in another area is called. Here, the contents of the internal registers (Q, I, AF, BC, DE, HL, IX, IY, AF ′, BC ′, DE ′, and HL ′ internal registers) of the main CPU 200a used in the use area. Thus, all the internal registers can be used in another area while protecting the contents of all the registers used in the used area. When such processing is completed, the return instruction “RET” refers to the stack area (for example, addresses F1E8h to F1E9h) of the use area, and the process returns to the use area.

  In the use area, the contents saved in the stack area of the use area (for example, addresses F1EAh to F1F1h) by the return instruction “POP GRP” are stored in internal registers (AF, BC, DE, and HL internal registers). Return to. Thus, the contents of the original back registers AF ', BC', DE ', and HL' that have been saved are temporarily stored in the front registers AF, BC, DE, and HL. Next, the contents of the front register BC, DE, HL and the contents of the back registers BC ′, DE ′, HL ′ are exchanged by the exchange instruction “EXX”, and the table is obtained by the exchange instruction “EX AF, AF ′”. The contents of the register AF and the contents of the back register AF ′ are exchanged. Thus, the contents of the original back registers AF ', BC', DE ', and HL' are restored.

  Subsequently, the contents saved in the stack area (for example, addresses F1F2h to F1FFh) by the return instruction “POP ALL” are collectively stored in the internal registers (Q, I, AF, BC, DE, HL, IX). , IY internal registers). Finally, the interrupt is permitted by the interrupt permission instruction “EI”.

  The instruction code of the program of FIG. 16A described in the use area is “DI”, “EX”, “EXX”, “EI” each 1 byte, “PUSH ALL”, “PUSH GRP”, “POP”. “ALL” and “POP GRP” are 2 bytes each, and “CALL SAMPLE1” is 3 bytes, so the total is 17 bytes (1 byte × 6 + 2 bytes × 4 + 3 bytes). Therefore, when the instruction code of the program in another area shown in FIG. 16B is described with an instruction code exceeding 17 bytes, the capacity of the used area can be saved for the area exceeding 17 bytes. Note that since there are usually many instruction codes (modules) for programs in different areas as shown in FIG. 16B, the number of bytes saved in each process is at least large in total. An effect can be obtained.

  In the above example, a part or all of the gaming machine test process, security related process, and advantageous section related process are arranged in another area. Is used for the purpose of testing processing for gaming machines, security-related processing, and advantageous section-related processing, and does not impair the fairness of the game.

  In addition, since the memory map is configured as shown in FIG. 11, the control area and the data area of the usage area and the different area in the condition (2) should be arranged in areas that are explicitly distinguished from each other. Is also satisfied.

  Further, the instruction code of the program in another area is statically called by the call instruction “CALL SAMPLE1” in FIG. 16A, and the call destination address is clearly “SAMPLE1”. The program placed in the area must be executed after being statically called from the program in the use area, and the callee address is clearly described in the program list at that time. Yes.

  Further, as shown in FIG. 16B, the instruction codes of the program in another area are modularized in units of functions, and the instruction codes “PUSH ALL”, “EX”, “EXX”, “PUSH” in FIG. The contents of all the internal registers (Q, I, AF, BC, DE, HL, IX, IY, AF ′, BC ′, DE ′, and HL ′) are saved by the “GRP”, and the instruction code “POP” is saved. The contents of all internal registers are restored by GRP, EXX, EX, and POP ALL. Even if the contents of the internal registers are destroyed while executing the instruction code of a program in another area Since the internal registers used in the used area remain the same, the condition (4) “Programs to be placed in different areas are modularized for each function, and when called, And "also met to protect in the contents of all the registers you are using.

  Also, as shown in FIGS. 16A and 16B, the instruction code is narrowed down to the call instruction “CALL” and the update is not executed even when referring to each other area in the main RAM 200c. Therefore, the condition (5) “access from the use area or another area to the RWM in each area can only be referred to and the update cannot be performed” is also satisfied.

  Also, as shown in FIGS. 16A and 16B, the call instruction “CALL” is described only in the use area, and the instruction code of the program in the use area is not called from another area. 6) “A subroutine in a control area of a use area cannot be called from a control area of another area” is also satisfied.

  In this way, it is possible to appropriately share roles between the use area and another area while ensuring the fairness of the slot machine 100. In addition, by placing the instruction code of another program that executes processing (game machine test processing, security-related processing, advantageous section-related processing) that can be placed in either the usage area or another area, the usage area The storage capacity to which the use program for executing the game control process that can only be arranged in the memory can be allocated (the use area has a margin), and the game control process can be expanded accordingly. Furthermore, since the contents of all internal registers (Q, I, AF, BC, DE, HL, IX, IY, AF ′, BC ′, DE ′, and HL ′ internal registers) are saved here, Even if all the internal registers including the back registers AF ′, BC ′, DE ′, and HL ′ are used in the game control process performed using the use area immediately before calling the instruction code of another area, It becomes possible to protect the contents of all the internal registers immediately before calling the instruction code of another area.

(Second embodiment)
In the first embodiment, an example in which the instruction code is 17 bytes in the use area has been described. In the second embodiment, the content of the internal register is saved in another area, thereby further reducing the amount of instruction code written in the use area. Here, in another area, the SP (stack pointer) in the used area is saved and the SP in the other area is set.

  Here, a specific bit flag (tz) whose value is changed by execution of a data transfer instruction (LD; load) is defined in the flag register (F register). As a result, it is possible to branch by a specific bit flag whose value is changed by execution of a data transfer instruction in addition to a branch by a normal zero flag that is set to 1 when all bits are 0 as a result of operation. The branch process used in the game control process can be described with a small number of instructions, and the storage capacity can be saved. On the other hand, by defining such a specific bit flag, when the stack area is used properly, the contents of the flag register may change due to data transfer accompanying the change of the stack pointer. Here, the contents of the flag register are saved in the stack area of the used area and restored from the stack area of the used area after returning from another area, so that the identity of the flag register is maintained before and after execution of the program in another area. . Therefore, by defining the specific bit flag, it is possible to save the capacity while effectively saving the capacity of the game control process in the use area.

  FIG. 17 is an explanatory diagram showing instruction codes of programs arranged in the control area of the use area and the control area of another area. Again, as in the first embodiment, the main CPU 200a, for example, in response to an interrupt signal every 1.49 msec, the instruction code of the program (use program) stored in the use area shown in FIG. The game control process is executed by, and a process of calling a program (separate program) in another area is executed as necessary. Then, the main CPU 200a performs processing by the instruction code of the program “SAMPLE2” stored in another area shown in FIG. 17B, and returns to processing of the program stored in the use area when the processing is completed. To do. Here, the program “SAMPLE2” is a typical example of the program called in the first embodiment, and actually, a plurality of programs (instruction codes) are stored in different areas as “SAMPLE2”.

  When the instruction code of the program shown in FIG. 17A is executed in the use area, first, the interrupt is prohibited by the interrupt disable instruction “DI”. Next, by the save instruction “PUSH AF”, the contents of the internal register AF of the main CPU 200a used in the use area are saved in the use area stack area (for example, addresses F1FEh to F1FFh) shown in FIG. Is done. Thus, at least the contents of the flag register are protected. When the contents of the internal register AF of the main CPU 200a used in the use area are saved, the main CPU 200a calls the instruction code of the program in another area shown in FIG. 17B by the call instruction “CALL SAMPLE2”. At this time, as shown in FIG. 17C, in the stack area of the use area (for example, addresses F1FCh to F1FDh), the return address of the calling instruction (the upper 8 bits of the return address in F1FDh and the lower address of the return address in F1FCh 8 bits) is saved.

  In another area, a predetermined process is executed according to the instruction code of the program shown in FIG. First, the stack pointer of the used area is saved (held) at the address indicated by the pointer EX_STCB by the load instruction “LD (EX_STCB), SP”. Then, an initial value of a stack pointer for another area is newly set by a load instruction “LD SP, @ SK2_ARE_BAS + 1”. Here, since the stack pointer can be used from the address F246h, the stack pointer is set to F247h (@ SK2_ARE_BAS + 1) obtained by adding one to the address. With such an instruction code, the stack pointer in the use area can be appropriately saved, and it is not necessary to be affected by the execution of a program in another area.

  Next, the contents of the internal registers (Q, I, AF, BC, DE, HL, IX, and IY) of the main CPU 200a used in the used area are collectively changed by the save instruction “PUSH ALL”. Saved to the stack area. In this way, as shown in FIG. 17D, the contents of the internal register are held in another stack area (for example, addresses F239h to F246h).

  Subsequently, the contents of the front register AF and the contents of the back register AF ′ are exchanged by the exchange instruction “EX AF, AF ′”, and the contents of the front registers BC, DE, HL are exchanged by the exchange instruction “EXX”. The contents of the registers BC ′, DE ′, and HL ′ are exchanged. Then, by the save instruction “PUSH GRP”, the contents of the internal registers (AF, BC, DE, and HL registers) (the original registers AF ′, BC ′, DE ′, HL ′) is saved in a stack area of another area. The address of the stack area to be saved is a younger address so as not to overwrite the contents saved by the save instruction “PUSH ALL”. Here, as a result, the contents of the original back registers AF ′, BC ′, DE ′, and HL ′ are saved. In this manner, as shown in FIG. 17D, the contents of the internal register are held in the stack area (for example, addresses F231h to F238h) of the use area. Here, since the contents of the original back registers AF ′, BC ′, DE ′, and HL ′ are also saved, the interrupt processing is temporarily executed in the use area, and the contents of the table registers AF, BC, DE, and HL are changed. Even if the program in the different area is executed in a state where it is saved in the back registers AF ′, BC ′, DE ′, HL ′, it is saved in the back registers AF ′, BC ′, DE ′, HL ′. The contents of the original table registers AF, BC, DE, and HL can be restored appropriately, and it is possible to reliably avoid the influence of the game control process in the used area.

  Thus, all the contents of the internal registers (Q, I, AF, BC, DE, HL, IX, IY, AF ′, BC ′, DE ′, and HL ′ registers) of the main CPU 200a used in the used area are all stored. When evacuated, for example, some or all of the above-described gaming machine test processing, security-related processing, and advantageous section-related processing are performed. Here, the contents of the internal registers (Q, I, AF, BC, DE, HL, IX, IY, AF ′, BC ′, DE ′, and HL ′) of the main CPU 200a used in the used area are Since all are saved, each internal register can be used in another area while protecting the contents of all registers used in the used area.

  When such processing is completed, the contents saved in another stack area (for example, addresses F231h to F238h) are restored to the internal registers (AF, BC, DE, and HL registers) by the return instruction “POP GRP”. Let In this way, the contents of the original back registers AF ', BC', DE ', and HL' that have been saved are temporarily stored in the front registers AF, BC, DE, and HL. Next, the contents of the front register BC, DE, HL and the contents of the back registers BC ′, DE ′, HL ′ are exchanged by the exchange instruction “EXX”, and the table is obtained by the exchange instruction “EX AF, AF ′”. The contents of the register AF and the contents of the back register AF ′ are exchanged. Thus, the contents of the original back registers AF ', BC', DE ', and HL' are restored.

  Subsequently, the contents saved in another stack area (for example, addresses F239h to F246h) by the return instruction “POP ALL” are collectively stored in the internal registers (Q, I, AF, BC, DE, HL, IX). , IY registers). In this way, all the contents of the internal registers (Q, I, AF, BC, DE, HL, IX, IY, AF ', BC', DE ', and HL') of the main CPU 200a are restored. Next, the contents of the address indicated by the pointer EX_STCB are returned to the stack pointer of the use area by the load instruction “LD SP, (EX_STCB)”. Next, the return instruction “RET” refers to the stack area (for example, addresses F1FCh to F1FDh) of the use area, and the process is returned to the use area.

  In the use area, the contents saved in the stack area (for example, addresses F1FEh to F1FFh) of the use area are restored to the internal register AF by a return instruction “POP AF”. Finally, the interrupt is permitted by the interrupt permission instruction “EI”.

  The instruction code of the program shown in FIG. 17A described in the use area is “DI”, “PUSH AF”, “POP AF”, “EI” is 1 byte each, and “CALL SAMPLE2” is 3 bytes. This is a byte (1 byte × 4 + 3 bytes). This is shorter than the instruction code (17 bytes) of the program in the use area shown in FIG. 16A in the first embodiment. Therefore, when the instruction code of the program in another area shown in FIG. 17B is described with an instruction code exceeding 7 bytes, the capacity of the used area can be saved for the area exceeding 7 bytes. As in the first embodiment, the number of instruction codes (modules) for programs in different areas as shown in FIG. 17B is usually plural, so the number of bytes saved in each process. At least, the total savings can be achieved.

  In the above example, a part or all of the gaming machine test process, security related process, and advantageous section related process are arranged in another area. Is used for the purpose of testing processing for gaming machines, security-related processing, and advantageous section-related processing, and does not impair the fairness of the game.

  In addition, since the memory map is configured as shown in FIG. 11, the control area and the data area of the usage area and the different area in the condition (2) should be arranged in areas that are explicitly distinguished from each other. Is also satisfied.

  Further, the instruction code of the program in another area is statically called by the call instruction “CALL SAMPLE2” in FIG. 17A, and the call destination address is clearly “SAMPLE2”. The program placed in the area must be executed after being statically called from the program in the use area, and the callee address is clearly described in the program list at that time. Yes.

  Further, as shown in FIG. 17B, the instruction codes of the program in another area are modularized in units of functions, and the instruction codes “PUSH ALL”, “EX”, “EXX”, “PUSH” in FIG. The contents of all the internal registers (Q, I, AF, BC, DE, HL, IX, IY, AF ′, BC ′, DE ′, and HL ′) are saved by the “GRP”, and the instruction code “POP” is saved. The contents of all internal registers are restored by GRP, EXX, EX, and POP ALL. Even if the contents of the internal registers are destroyed while executing the instruction code of a program in another area Since the internal registers used in the used area remain the same, the condition (4) “Programs to be placed in different areas are modularized for each function, and when called, And "also met to protect in the contents of all the registers you are using.

  Further, as shown in FIGS. 17A and 17B, the instruction code is narrowed down to the call instruction “CALL” and the update is not executed even when the respective areas in the main RAM 200c are referred to. Therefore, the condition (5) “access from the use area or another area to the RWM in each area can only be referred to and the update cannot be performed” is also satisfied.

  In addition, as shown in FIGS. 17A and 17B, the calling instruction “CALL” is described only in the use area, and the instruction code of the use area program is not called from another area. 6) “A subroutine in a control area of a use area cannot be called from a control area of another area” is also satisfied.

  In this way, it is possible to appropriately share roles between the use area and another area while ensuring the fairness of the slot machine 100. In addition, by placing the instruction code of another program that executes processing (gaming machine test processing, security-related processing, advantageous section-related processing) that can be placed in either the use area or another area in another area, The storage capacity to which the use program for executing the game control process that can be arranged only in the use area can be allocated (the use area has a margin), and the game control process can be expanded accordingly. In the second embodiment, since the instruction code of the program in the use area is as small as 7 bytes compared with 17 bytes in the first embodiment, game control processing is also possible compared to the first embodiment. It is possible to increase the storage capacity to which the program to be used for executing can be allocated. Here, the contents of all the internal registers (Q, I, AF, BC, DE, HL, IX, IY, AF ′, BC ′, DE ′, and HL ′ registers) are saved. Even if all internal registers including the back registers AF ′, BC ′, DE ′, and HL ′ are used in the game control process performed using the used area immediately before calling the instruction code of the area, It becomes possible to protect the contents of all the internal registers immediately before calling the instruction code of the area.

(Third embodiment)
In the second embodiment, an example in which the instruction code is 7 bytes in the use area has been described. In the third embodiment, on the premise that the contents of the internal register are saved in another area, the amount of instruction code in the used area is further reduced by restricting the use of the internal register used in the other area. . Specifically, in the use area, the front registers AF, BC, DE, and HL are used, and the back registers AF ′, BC ′, DE ′, and HL ′ are not used. In another area, the other front registers Q, I, HL, IX, IY and the back registers AF ′, BC ′, DE ′, HL ′ are not used (restricted use), and the front registers AF, BC, Only the contents of DE and HL are saved. As described above, the usage mode (specification) of the internal register can be different for each model of the slot machine 100. Further, here, the interrupt enable instruction “EI” is also executed in another area by utilizing the characteristic that the interrupt enable instruction “EI” becomes valid (interrupt enable) after execution of the next instruction.

  FIG. 18 is an explanatory diagram showing instruction codes of programs arranged in the control area of the use area and the control area of another area. Also here, as in the first and second embodiments, the main CPU 200a, for example, in accordance with an interrupt signal every 1.49 msec, the program stored in the use area shown in FIG. The game control process is executed according to the instruction code of the use program), and the process of calling the program (separate program) in another area is executed as necessary. Then, the main CPU 200a performs processing by the instruction code of the program “SAMPLE3” stored in another area shown in FIG. 18B, and returns to the processing of the program stored in the use area when the processing is completed. To do. Here, the program “SAMPLE3” is a typical example of the program called in the first embodiment, and actually, a plurality of programs (instruction codes) are stored in different areas as “SAMPLE3”.

  When the instruction code of the program of FIG. 18A is executed in the use area, first, an interrupt is prohibited by the interrupt disable instruction “DI”. Next, the main CPU 200a calls the instruction code of the program in another area shown in FIG. 18B by the call instruction “CALL SAMPLE3” without saving the contents of the internal register. At this time, as shown in FIG. 18C, in the stack area of the use area (for example, addresses F1FEh to F1FFh), the return address of the call instruction (the upper 8 bits of the return address in F1FFh and the lower address of the return address in F1FEh) 8 bits) is saved.

  In another area, predetermined processing is executed in accordance with the instruction code of the program shown in FIG. First, by exchanging the contents of the front register AF and the back register AF ′ with the exchange command “EX AF, AF ′”, the contents of the front register AF originally (just before calling the instruction code in another area) are reversed. It is saved in the register AF ′. Further, the contents of the front registers BC, DE, and HL are exchanged by exchanging the contents of the original table registers BC, DE, and HL with the contents of the back registers BC ′, DE ′, and HL ′ by the exchange instruction “EXX”. Saved in the registers BC ′, DE ′, and HL ′. Thus, the contents of the internal registers (AF, BC, DE, and HL internal registers) can be saved without setting the stack pointer.

  Thus, when all the contents of the internal registers (AF, BC, DE, and HL internal registers) of the main CPU 200a used in the usage area are saved, for example, the above-mentioned test processing for gaming machines, security related processing, Part or all of the advantageous section related processing is performed. Here, all the contents of the internal registers (AF, BC, DE, and HL internal registers) of the main CPU 200a used in the use area are saved, and the use of other internal registers is restricted. Therefore, it is possible to use each internal register that is not restricted in use while protecting the contents of the internal register used in the use area.

  When such processing is completed, the contents of the table registers BC, DE, and HL and the contents of the back registers BC ′, DE ′, and HL ′ are exchanged by the exchange command “EXX”, whereby the original table registers BC, DE, and HL are exchanged. The contents of are restored. Further, the original contents of the front register AF are restored by exchanging the contents of the front register AF and the contents of the back register AF 'by the exchange instruction "EX AF, AF'".

  As described above, after the instruction code of the program in another area is executed in a single line, in the third embodiment, the interrupt enable instruction “EI” is executed before the return instruction “RET”. The interrupt permission instruction “EI” has a characteristic that becomes valid (interrupt permission) after execution of the next instruction. Therefore, even if it is executed before the next instruction “RET”, there is no problem because the interrupt is permitted after the processing is returned to the use area. Then, the return instruction “RET” refers to the stack area (for example, addresses F1FEh to F1FFh) of the use area, and the process is returned to the use area. Note that an interrupt is substantially permitted after the return instruction “RET”.

  The instruction code of the program of FIG. 18A described in the use area is 4 bytes (1 byte + 3 bytes) because “DI” is 1 byte and “CALL SAMPLE3” is 3 bytes. This is because the program instruction code (17 bytes) in the use area shown in FIG. 16A in the first embodiment and the program instruction code in the use area shown in FIG. 17A in the second embodiment. Shorter than (7 bytes). Therefore, when the instruction code of the program in another area shown in FIG. 18B is described with an instruction code exceeding 4 bytes, the capacity of the used area can be saved for the area exceeding 4 bytes. As in the first and second embodiments, the instruction codes (modules) of programs in different areas as shown in FIG. At least the total number of bytes saved in processing can be greatly reduced.

  In the above example, a part or all of the gaming machine test process, security related process, and advantageous section related process are arranged in another area. Is used for the purpose of testing processing for gaming machines, security-related processing, and advantageous section-related processing, and does not impair the fairness of the game.

  In addition, since the memory map is configured as shown in FIG. 11, the control area and the data area of the usage area and the different area in the condition (2) should be arranged in areas that are explicitly distinguished from each other. Is also satisfied.

  Further, the instruction code of the program in another area is statically called by the call instruction “CALL SAMPLE3” in FIG. 18A, and the call destination address is clearly “SAMPLE3”. The program placed in the area must be executed after being statically called from the program in the use area, and the callee address is clearly described in the program list at that time. Yes.

  Further, as shown in FIG. 18B, the instruction code of the program in another area is modularized in units of functions, and the use is permitted by the instruction codes “EX” and “EXX” in FIG. 18B. The contents of the internal registers (AF, BC, DE, and HL internal registers) are saved, and the contents of the internal registers are restored by the instruction codes “EXX” and “EX”. Even if the contents of the internal register are destroyed during execution of the code, the identity of the internal register used in the used area is maintained. When it is called and called, it protects the contents of all registers used in the used area.

  Also, as shown in FIGS. 18A and 18B, the instruction code is narrowed down to the call instruction “CALL” and the update is not executed even when referring to each other area in the main RAM 200c. Therefore, the condition (5) “access from the use area or another area to the RWM in each area can only be referred to and the update cannot be performed” is also satisfied.

  Further, as shown in FIGS. 18A and 18B, the calling instruction “CALL” is described only in the use area, and the instruction code of the use area program is not called from another area, so that the condition ( 6) “A subroutine in a control area of a use area cannot be called from a control area of another area” is also satisfied.

  In this way, it is possible to appropriately divide roles between the use area and another area while ensuring the fairness of the slot machine. In addition, by placing the instruction code of another program that executes processing (game machine test processing, security-related processing, advantageous section-related processing) that can be placed in either the usage area or another area, the usage area The storage capacity to which the use program for executing the game control process that can only be arranged in the memory can be allocated (the use area has a margin), and the game control process can be expanded accordingly. In the third embodiment, the instruction code of the program in the use area can be reduced to 4 bytes compared with 17 bytes in the first embodiment and 7 bytes in the second embodiment. Compared with the example and the second embodiment, it is possible to increase the storage capacity to which the use program for executing the game control process can be allocated. Here, since the contents of a part of the internal registers (AF, BC, DE, and HL internal registers) are saved, game control performed using the used area immediately before calling the instruction code of another area Even if the table registers AF, BC, DE, and HL are used in the processing, it is possible to protect the contents of the internal register immediately before calling the instruction code in the other area.

  In the third embodiment, since the instruction codes “PUSH” and “POP” are not used, the stack pointer need not be used unnecessarily, and the stack area can be assigned to another process.

  Further, by including the instruction code “EI” in the instruction code of the program in another area, it is possible to secure the storage capacity of the used area while executing the interrupt permission at an appropriate timing. In the third embodiment, the mode in which the instruction code “EI” is included in the instruction code of the program in another area has been described, but it goes without saying that it can be applied to the first embodiment and the second embodiment. In this case, as in the third embodiment, the instruction code “EI” is described immediately before the instruction code “RET” in the program in another area, and “EI” is deleted from the program in the use area instead. it can.

  In the above-described embodiment, since there is no limitation on the storage capacity in another area, an example in which the instruction code in the used area is transferred to another area as much as possible has been described. However, the interrupt time (interrupt cycle) Depending on the length of the instruction code of the program, etc., it may be adjusted as appropriate to which area. For example, if there is still room in the use area, or if the processing becomes complicated, such as when there is a problem if all program instruction codes are allocated to another area, interrupts are prohibited by placing the program instruction code in another area. When the time from interrupt to interrupt permission exceeds the interrupt time (the time between interrupts, for example, 1.49 msec), use part or all of the instruction code of the program to be placed in another area You may arrange in.

  In the embodiment described above, an example in which some or all of the gaming machine test process, the security related process, and the advantageous section related process are arranged in another area has been described. You may distribute to a use area and another area, and you may distribute any process only to a use area. The distribution unit may be a module (program) unit or an instruction code unit obtained by further dividing the module. Here, the module unit is a process for each test item and test method if it is a test process for gaming machines, and if it is a security-related process, the abnormal states “backflow error” and “empty error” shown in FIG. ”,“ Discharge Clogging Error ”,“ Discharge Abnormal Error ”,“ Over Error ”,“ Residence Error ”,“ Backup Error ”,“ Door Open Error ”,“ Loading Error Error ”,“ Display Judgment Error Error ”,“ RWM It is a process of determination and notification (display) for each of “abnormal error” and “setting value abnormal error”, and if it is an advantageous section related process, it is an advantageous section ratio, a 6000 game continuous character ratio, a 6000 game character ratio, Total cumulative feature ratio, total cumulative feature ratio calculation processing, total number of games, staying games, total number of payouts, consecutive feature payouts, cumulative feature payouts A.

  In one slot machine 100, a program stored in another area is called based on only one of the first embodiment, the second embodiment, and the third embodiment described above. It is. However, the present invention is not limited to this, and in one slot machine 100, the calling methods of the first embodiment, the second embodiment, and the third embodiment may be mixed.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Is done.

  For example, in the above-described embodiment, the main control board 200 and the sub control board 202 are arranged so as to share a functional part for proceeding with the game, but the functional part of the main control board 200 is assigned to the sub control board 202. Alternatively, the functional units of the sub control board 202 may be arranged on the main control board 200, or all the functional units may be arranged on one control board.

  Further, the processes performed by the main control board 200 and the sub control board 202 described above do not necessarily have to be processed in time series in the order described in the flowchart, and may include processes in parallel or by a subroutine.
