When the data are damaged, an address in which the damaged data are stored is displayed to a liquid crystal display device 31.

Description

  The present invention relates to a gaming machine provided with storage means capable of rewriting data.

  The conventional gaming machine is configured to control a special game (bonus) when a winning ball is won at a start opening provided on the game board, and when a jackpot lottery is won. . In such special games, the big prize opening provided on the game board is opened to facilitate the winning of the game ball, and the prize ball corresponding to the game ball won in the big prize opening is paid out to the player. It is like that.

  In addition, since it is generally difficult to shift to a special game, in order to prevent the game from getting bored, a large number of game data (image data etc.) is stored in the effect ROM, and based on such game data, A predetermined effect is executed in an image display device such as a liquid crystal display device, a light emitting device such as a lamp / LED, and a sound output device such as a speaker.

  In such a gaming machine, in order to prevent a predetermined effect from being executed (for example, the effect image is not normally displayed) due to the damage of game data, the effect ROM is turned on when the power is turned on. A game machine that performs an inspection using inspection data such as a checksum on the game data stored in the game data, and displays a display that can specify an abnormal performance ROM when the inspection result is determined to be abnormal Is known (see Patent Document 1).

JP 2005-131144 A

  However, in the gaming machine described in Patent Document 1, when it is determined that the game data stored in the effect ROM is abnormal, it is necessary to replace the entire effect ROM (CGROM) as a measure for the abnormality. This will lead to cost increase.

  Further, in order to suppress the cost increase and to re-use the effect ROM, if the effect ROM is configured with a rewritable storage means, it is determined that the game data stored in the effect ROM is damaged and thus abnormal. When it is done, it is necessary to rewrite all the game data including normal game data, or to repair the damaged game data while searching for the damaged game data, and the repair work cannot be performed efficiently. There was a problem.

  An object of the present invention is to provide a gaming machine that can perform a repair work efficiently even if a part of data stored in a storage means capable of rewriting data is damaged.

According to the first aspect of the present invention, a plurality of game data used for a game is stored in association with each address, and the game data storage means (for example, CGROM 151) capable of rewriting the game data is stored in the game data storage means. An informing means (for example, the liquid crystal display device 31) for informing that the stored game data is damaged, and when a predetermined condition is established, the predetermined data for each predetermined address range in the game data storage means When the inspection value is calculated by the inspection value calculating means (for example, the host CPU 150a) for calculating the inspection value (for example, checksum) of the game data associated with the address range, the calculation value is calculated. Normality determining means (for example, the host CPU 150a) for determining whether or not the game data is normal based on the inspection value that has been set, Normal inspection value storage means for storing an inspection value for each predetermined address range to be calculated by the inspection value calculation means when the game data is not damaged as a normal inspection value and incapable of rewriting game data (For example, host ROM 150c),
The normality determination means collates the inspection value calculated by the inspection value calculation means with the normal inspection value stored in the normal inspection value storage means, and for each predetermined address range in the game data storage means When the normality of the game data is determined and the notification means determines that the game data is not normal by the normality determination means, the game data determined to be normal is stored in the game data storage means. The notification is performed in a specific notification mode that specifies an address range.

  According to a second aspect of the present invention, in the gaming machine according to the first aspect of the present invention, the game machine further includes an effect control means (for example, a host CPU 150a) for instructing the notification means to execute a predetermined effect. When there is an instruction to execute the predetermined effect from the effect control means, notification in an effect notification mode corresponding to the predetermined effect is performed, and the effect control means determines that the normality determination means is not normal. Then, the instruction to execute the predetermined effect is restricted until it is determined that the normality determination means is normal.

  According to a third aspect of the present invention, in the gaming machine according to the first or second aspect, the game data storage means stores image data as the game data and provides an effect symbol for informing the result of the game. A plurality of image data corresponding to the first address range are stored in association with the first address range, and a plurality of image data corresponding to the character design for performing effects related to the game are stored in association with the second address range. It is characterized by that.

Here, “game data” refers to various data such as program data, image data, pallet data, sound data, ramp data, and the like unless otherwise limited. In addition, “predetermined condition is satisfied” means that, in an embodiment described later, a power supply voltage is supplied to an inspection value calculation unit (for example, the host CPU 150a), but a predetermined time (for example, 1 hour) has elapsed. Or a predetermined external signal may be input.
“For each predetermined address range” means a range of a plurality of addresses in the embodiment described later, but may mean one address range. In addition, “every predetermined address range” may be the same range (for example, 1000000H), or the first address range may be different from the second address range. Good.
“A specific notification mode for specifying a predetermined address range in which game data determined to be abnormal is stored in the game data storage means” refers to an image that displays a predetermined address range in an embodiment described later. However, it may be a sound that outputs a range of a predetermined address, or may be a light emission mode of a light emitting device corresponding to the range of a predetermined address.

  According to the present invention, even if a part of data stored in the storage unit capable of rewriting data is damaged, the predetermined game data stored in the predetermined notification mode is notified by the notification in the specific notification mode in the notification unit. Since the address range can be known, the repair work can be performed efficiently.

The sub ROM 120b of the effect control board 120 stores a program for effect control, data necessary for determining various games, and a table.
For example, an effect pattern determination table for determining an effect pattern based on a variation pattern designation command received from the main control board, an effect symbol determination table for determining a combination of effect symbols 36 to be stopped, and the like are stored in the sub ROM 120b. Has been. Note that the above-described table is merely an example of characteristic tables among the tables in the present embodiment, and a number of other tables and programs (not shown) are provided for the progress of the game. ing.

The sub RAM 120c of the effect control board 120 functions as a data work area when the sub CPU 120a performs arithmetic processing, and has a plurality of storage areas.
The sub RAM 120c is provided with a game state storage area, an effect mode storage area, an effect pattern storage area, an effect symbol storage area, and the like. Note that the above-described storage area is merely an example, and many other storage areas are provided.

  The payout control board 130 performs payout control of game balls. The payout control board 130 includes a one-chip microcomputer including a payout CPU, a payout ROM, and a payout RAM (not shown), and is connected to the main control board 110 so as to be capable of bidirectional communication. The payout CPU reads out the program stored in the payout ROM based on the input signals from the payout ball count detection switch 132, the door opening switch 133, and the timer for detecting whether or not the game ball has been paid out, and performs arithmetic processing. At the same time, based on the processing, the corresponding data is transmitted to the main control board 110. Further, a payout motor 131 of a payout device for paying out a predetermined number of game balls from the game ball storage unit is connected to the output side of the payout control board 130. The payout CPU reads out a predetermined program from the payout ROM based on the payout number designation command transmitted from the main control board 110, performs arithmetic processing, and controls the payout motor 131 of the payout device to give a predetermined game ball. Pay out. At this time, the payout RAM functions as a data work area at the time of calculation processing of the payout CPU.

  The lamp control board 140 controls the lighting of the effect lighting device 34 provided on the game board 2 and controls the driving of the motor for changing the light irradiation direction. In addition, energization control is performed on a drive source such as a solenoid or a motor that operates the effect driving device 33. The lamp control board 140 is connected to the effect control board 120 and performs the above-described controls based on various commands transmitted from the effect control board 120.

The image control board 150 is connected to the liquid crystal display device 31 and the audio output device 32, and based on various commands transmitted from the effect control board 120, image display control and audio output device in the liquid crystal display device 31. The sound output control at 32 is performed.
Detailed description of the image control board 150 will be described later with reference to the block diagram of the image control board of FIG.

  The launch control board 160 performs launch control of the game ball. The launch control board 160 has a touch sensor 3a and a launch volume 3b connected to the input side, and a launch solenoid 4a and a ball feed solenoid 4b connected to the output side. The firing control board 160 inputs a touch signal from the touch sensor 3a and performs control to energize the firing solenoid 4a and the ball feed solenoid 4b based on the voltage supplied from the firing volume 3b.

  The touch sensor 3a is provided in the inside of the operation handle 3, and is comprised from the electrostatic capacitance type proximity switch using the change of the electrostatic capacitance by the player touching the operation handle 3. When the touch sensor 3a detects that the player has touched the operation handle 3, the touch sensor 3a outputs a touch signal that permits energization of the firing solenoid 4a to the firing control board 160 (see FIG. 4). As a major premise, the launch control board 160 is configured not to launch the game ball 200 into the game area 6 unless a touch signal is input from the touch sensor 3a.

  The firing volume 3b is provided directly connected to a rotating portion around which the operation handle 3 rotates, and is composed of a variable resistor. The firing volume 3b divides a constant voltage (for example, 5V) applied to the firing volume 3b by a variable resistor, and supplies the divided voltage to the launch control board 160 (the voltage to be supplied to the launch control board 160). Variable). The launch control board 160 energizes the launch solenoid 4a based on the voltage divided by the launch volume 3b, and rotates the launch member 4c directly connected to the launch solenoid 4a, thereby playing the game ball 200 in the game. Fire into area 6.

  The firing solenoid 4a is composed of a rotary solenoid, and a launching member 4c is directly connected to the firing solenoid 4a, and the launching member 4c is rotated by rotating the launching solenoid 4a.

  Here, the rotation speed of the firing solenoid 4a is set to about 99.9 (times / minute) based on the frequency based on the output period of the crystal oscillator provided on the firing control board 160. As a result, the number of games played per minute is about 99.9 (pieces / minute) because one shot is fired every time the firing solenoid rotates. That is, one game ball is fired about every 0.6 seconds.

  The ball feed solenoid 4b is composed of a linear solenoid, and sends out the game balls in the tray 40 one by one toward the launch member 4c directly connected to the launch solenoid 4a.

(Block diagram of image control board)
Next, image display control will be described using the block diagram of the image control board 150 in FIG.

The image control board 150 includes a host CPU 150 a, a host RAM 150 b, a host ROM 150 c, a CGROM 151, a VRAM 153, a VDP (Video Display Processor) 2000, and a sound control circuit 3000 for performing image display control of the liquid crystal display device 31.
In addition, the image control board 150 includes other well-known electronic components such as a crystal oscillator (not shown).

Based on the effect pattern designation command received from the effect control board 120, the host CPU 150a instructs the liquid crystal display device 31 to display the image data stored in the CGROM 151 in the VDP 2000. Such an instruction is performed by setting data in the control register 2010 in the VDP 2000 and outputting a display list including drawing control command groups.
In addition, when receiving a V blank interrupt signal or a drawing end signal from the VDP 2000, the host CPU 150a appropriately performs an interrupt process.

  Furthermore, the host CPU 150a also instructs the audio control circuit 3000 to output predetermined audio data to the audio output device 32 based on the effect pattern designation command received from the effect control board 120.

  The host RAM 150b is built in the host CPU 150a, functions as a data work area when the host CPU 150a performs arithmetic processing, and temporarily stores data read from the host ROM 150c.

  The host ROM 150c has a non-volatile and non-rewritable mask ROM, and the product life of the host ROM 150c is extremely long.

The host ROM 150c stores a control processing program for the host CPU 150a, a display list generation program for generating a display list, animation pattern information for displaying an animation of a production pattern, and the like. The animation pattern is referred to when displaying an animation corresponding to the production pattern, and stores a combination of animation scene information included in the production pattern, a display order of each animation scene information, and the like. The animation scene information stores information such as target data (sprite identification number, transfer source address, etc.), parameters (sprite display position, transfer destination address, etc.), drawing method, and the like.
Further, in the host ROM 150c of the present embodiment, checksum data of sprite data (symbol data) in the range of the first address address of the CGROM 151 to be described later, sprite data (character data) in the range of the second address address. Checksum data, checksum data of sprite data (background data) in the range of the third address address, checksum data of all movie data in the range of the fourth address address, and the range of the fifth address address Checksum data of certain pallet data is stored.
Details will be described using the memory maps of the CGROM 151 and the host ROM 150c in FIG.

  The CGROM 151 is composed of non-volatile, rewritable flash memory, EEPROM, EPROM, etc., and depending on the product, it is vulnerable to oxidation, ultraviolet light, static electricity, etc., and the number of writable times is limited. Product life is short.

  The CGROM 151 includes sprite data (so-called single image data) including a collection of pixel information in a predetermined range of pixels (for example, 32 × 32 pixels) and movie data (so-called multiple images) including a plurality of image data. Data), pallet data in which color number information for specifying color numbers and display color information for actually displaying colors are associated with each other. Here, the pixel information is composed of color number information specifying a color number for each pixel and an α value indicating the transparency of the image.

According to the present embodiment, the CGROM 151 mounted on the image control board 150 constitutes “game data storage means”. However, if the CGROM 151 is a storage means capable of rewriting data, the main board mounted on the main control board 110 is used. The ROM 110b may constitute game data storage means, or the sub ROM 120b mounted on the effect control board 120 may constitute game data storage means.
Furthermore, according to the present embodiment, the host ROM 150c mounted on the image control board 150 constitutes a normal inspection value storage unit, but if it is a storage unit that cannot rewrite data, it is mounted on the main control board 110. The main ROM 110b thus configured may constitute normal inspection value storage means, or the sub ROM 120b mounted on the effect control board 120 may constitute normal inspection value storage means.

  Note that according to the present embodiment, the present invention is not limited to the data compression target in the CGROM 151. That is, all the data stored in the CGROM 151 may be compressed and stored, or only a part of the data may be compressed and stored. However, it is desirable not to compress the palette data because when the data deteriorates, the display color of the image directly changes and the image quality changes drastically.

The VRAM 153 is composed of an SRAM that can write or read image data at high speed.
The VRAM 153 also includes a display list storage area for temporarily storing the display list output from the host CPU 150a, a development storage area for storing image data stored in the CGROM 151, and a frame buffer for drawing or displaying an image. Etc. The VRAM 153 also stores palette data.

  The VDP 2000 is a so-called image processor, which draws the image data stored in the CGROM 151 in the frame buffer of the VRAM 153 based on an instruction from the host CPU 150a, and also generates a video signal (RGB) from the image data drawn in the frame buffer of the VRAM 153. Signal etc.) and output to the liquid crystal display device.

  The sound control circuit 3000 includes an audio ROM that stores a large number of audio data. The sound control circuit reads out a predetermined program based on a command transmitted from the effect control board 120, and an audio output device. The sound output control at 32 is performed.

(Memory map of CGROM and host ROM)
Next, data of contents stored in the CGROM 151 and the host ROM 150c will be described using the memory map of the CGROM and the host ROM shown in FIG.
Here, FIG. 6A shows a memory map of the CGROM 151, and FIG. 6B shows a memory map of the host ROM 150c.

As shown in the memory map of the CGROM 151 in FIG. 6A, the sprite data that causes the liquid crystal display device 31 to display the effect design 36 is in the address address range (first address address range) 0000000H to 0FFFFFFH of the CGROM 151. (Symbol data) is stored.
In addition, sprite data (character data) for displaying characters such as animals and characters on the liquid crystal display device 31 is stored in the address address range (second address address range) of 1000000H to 1FFFFFFH of the CGROM 151. The address address range of 2FFFFFFH (third address address range) stores sprite data (background data) for displaying the background on the liquid crystal display device 31, and the address address range of 3000000H to 3FFFFFFH (fourth address). Movie data is stored in the (address range), and palette data is stored in the address address range (5th address range) of 4000000H to 4FFFFFFH. It should be noted that when the address of the CGROM 151 is 5000000H or later, it is unused data.
As described above, in the present embodiment, the contents of data are stored in association with each range of the predetermined address address of the CGROM 151.

Here, the right column of FIG. 6A shows the value of the checksum created by the host CPU 150a when all data stored in the range of the predetermined address address of the CGROM 151 is normal. .
In this embodiment, when the data in the predetermined address address range of the CGROM 151 is normal, the checksum created in the address address range of 0000000H to 0FFFFFFH of the CGROM 151 is “1234”, for example, 1000000H to 1FFFFFFH The checksum created in the address address range is, for example, “2345”, and the checksum created in the address address range from 2000000H to 2FFFFFFH is, for example, “3456”, created in the address address range from 3000000H to 3FFFFFFH. The checksum to be generated is, for example, “4567”, and the checksum created in the address address range of 4000000H to 4FFFFFFH is, for example, “5678”.

  As shown in the memory map of the host ROM 150c in FIG. 6B, the host ROM 150c has an address address range of 0000000H to 0FFFFFFH, a control processing program for the host CPU 150a, a display list generation program for generating a display list, and the like. The programs of the various modules are stored. Also, animation pattern information and data necessary for executing programs of various modules are stored in the address range of 1000000H to 1FFFFFFH in the host ROM 150c.

  Then, it is created when normal data is stored in the address of 0000000H to 0FFFFFFH of the CGROM 151 at a predetermined address in the range of the address of the host ROM 150c in the range of 2000000H to 20FFFFFH. The checksum (for example, “1234”) is stored. Further, it is created when normal data is stored in the addresses 1000000H to 1FFFFFFH of the CGROM 151 at a predetermined address in the range of 2100000H to 21FFFFFH as the address of the host ROM 150c. Is stored, for example, “2345”. Also, it is created when normal data is stored in the address of 2000000000H to 2FFFFFFH of the CGROM 151 at a predetermined address in the range of the address of the host ROM 150c of 2200000H to 22FFFFFH as the background checksum data. A checksum (for example, “3456”) is stored. Further, it is created when normal data is stored in the addresses 3000000H to 3FFFFFFH of the CGROM 151 at a predetermined address in the range of 2300000H to 23FFFFFH as the address of the host ROM 150c. A checksum (for example, “4567”) is stored. Also, it is created when normal data is stored in the address of 4000000H to 4FFFFFFH of CGROM 151 at a predetermined address in the range of the address of the host ROM 150c in the range of 2400000H to 24FFFFFH as pallet checksum data. A checksum (for example, “5678”) is stored. Note that the data after the 2500,000H address in the host ROM 150c is unused data.

  As described above, since the contents of data are stored in association with each predetermined address range of the CGROM 151 and the checksum of each predetermined address range can be confirmed, the data stored in the rewritable CGROM 151 is stored. Even if an abnormality occurs, the address range of the abnormal data stored in the CGROM 151 can be specified and the contents of the abnormal data can be grasped.

  Next, details of various tables stored in the main ROM 110b will be described with reference to FIGS.

(Big hit judgment table)
FIG. 7 (a-1) and FIG. 7 (a-2) are diagrams showing a jackpot determination table used for the “big winning lottery”. FIG. 7 (a-1) is a jackpot determination table referred to in the first special symbol display device 20, and FIG. 7 (a-2) is a jackpot determination table referred to in the second special symbol display device 21. is there. In the tables of FIG. 7A-1 and FIG. 7A-2, although the winning probabilities for small hits are different, the jackpot probabilities are the same.

Specifically, the big hit determination table is used to determine whether “big hit”, “small hit”, or “losing” based on the current probability gaming state and the acquired random number for determining a special symbol.
For example, according to the jackpot determination table for the first special symbol display device shown in FIG. 7 (a-1), the two special symbol determination disturbances “7” and “8” are in the low probability gaming state. The number is determined to be a big hit. On the other hand, in the high probability gaming state, 20 special symbol determination random numbers “7” to “26” are determined to be big hits.
Further, according to the jackpot determination table for the first special symbol display device shown in FIG. 7 (a-1), the random number value for special symbol determination is obtained in the low probability gaming state or the high probability gaming state. In the case of four special symbol determination random numbers “50”, “100”, “150”, and “200”, it is determined as “small hit”. If the random number is other than the above, it is determined as “lost”.
Therefore, since the random number range of the special symbol determination random number value is 0 to 598, the probability of being determined to be a big hit in the low probability gaming state is 1 / 299.5, and in the high probability gaming state, The probability to be determined is 10 times up to 1 / 29.9. In the first special symbol display device, the probability of being determined to be a small hit is 1 / 149.75 regardless of whether the game state is a low probability game state or a high probability game state.

(Winning judgment table)
FIG. 7B is a diagram showing a hit determination table used for “normal symbol lottery”.
Specifically, the winning determination table determines whether it is “winning” or “lost” based on the presence / absence of the short-time gaming state and the acquired random number for normal symbol determination.
For example, according to the hit determination table shown in FIG. 7B, when in the non-time-saving gaming state, it is determined that one specific normal symbol determination random value of “0” is a win. On the other hand, when in the short-time gaming state, it is determined that 65535 specific random symbols for determining normal symbols from “0” to “65534” are hit. If the random number is other than the above, it is determined as “lost”.
Therefore, since the random number range of the normal symbol determination random number value is 0 to 65535, the probability of being determined to be hit in the non-short-time gaming state is 1/65536, and the probability of being determined to be winning in the time-short gaming state is 65535/65536 = 1 / 1.00002.

(Design determination table)
FIG. 8 is a diagram showing a symbol determination table for determining a special symbol stop symbol.
FIG. 8A is a symbol determination table that is referred to in order to determine a stop symbol at the time of a big hit, and FIG. 8B is a symbol that is referred to in order to determine a stop symbol at the time of a big hit. FIG. 8C is a symbol determination table that is referred to in order to determine a stop symbol in the event of a loss.

Specifically, according to the symbol determination table shown in FIG. 8, the type of special symbol display device (the type of the start opening in which the game ball has won) and the game ball in the first start port 14 or the second start port 15 The special symbol type (stop symbol data) is determined based on the jackpot symbol random number value or the small bonus symbol random number value acquired when the ball is entered.
For example, the first special symbol display device refers to the symbol determination table shown in FIG. 8A in the case of a jackpot, and if the acquired jackpot symbol random number value is “55”, the stop symbol data is “03”. ”(Special symbol 3 (first positive variation jackpot 3)) is determined. Further, in the first special symbol display device, the symbol determination table shown in FIG. 8B is referred to at the time of small hitting, and if the acquired random number for small hitting symbol is “50”, as the stopped symbol data “08” (special symbol B (small hit B)) is determined. In the case of a loss, “00” (special symbol 0 (lost)) is determined as stop symbol data without referring to any random value.

  Then, at the time of starting the change of the special symbol, an effect designating command is generated as special symbol information based on the determined special symbol type (stop symbol data). Here, the effect designating command is composed of 2-byte data, and 1-byte MODE data for identifying the control command classification and 1-byte DATA indicating the contents of the control command to be executed. It consists of data. The same applies to a variation pattern designation command described later.

  As will be described later, since the game state after the jackpot game and the type of jackpot game are determined by the type of special symbol (stop symbol data), the type of special symbol is the game state after the jackpot game ends. It can be said that the type of jackpot game is determined.

(Description of gaming state)
Next, the gaming state when the game progresses will be described. In this embodiment, there are “low probability gaming state” and “high probability gaming state” as the states related to the jackpot lottery, and “non-short-time gaming state” is the state relating to the pair of movable pieces 15b that the second starting port 15 has. And “short-time gaming state”. The state relating to the jackpot lottery (low probability gaming state, high probability gaming state) and the state relating to the pair of movable pieces 15b (non-short-time gaming state, short-time gaming state) can be associated with each other and are independent. You can also. In other words,
(1) “Low probability gaming state” and “Time saving gaming state”
(2) “Low probability gaming state” and “non-temporary gaming state”
(3) “High probability gaming state” and “short time gaming state”
(4) It is possible to provide a “high probability gaming state” and a “non-temporary gaming state”.
Note that the gaming state when the game is started, that is, the initial gaming state of the gaming machine 1 is a “low probability gaming state” and is set to a “non-short-time gaming state”. Is referred to as a “normal gaming state”.

In the present embodiment, the “low probability gaming state” means that in the jackpot lottery performed on the condition that a game ball has entered the first starting port 14 or the second starting port 15, the winning probability of the jackpot is 1 / The game state set to 299.5. On the other hand, the “high probability gaming state” means a gaming state in which the jackpot winning probability is set to 1 / 29.95. Therefore, in the “high probability gaming state”, it is easier to win a jackpot than in the “low probability gaming state”. Note that a high-probability game flag, which will be described later, is set in this high-probability game state, and the high-probability game flag is off in the low-probability game state.
Further, the low probability gaming state is changed to the high probability gaming state after the jackpot game described later is finished.

  In the present embodiment, the “non-short game state” means that, in the normal symbol lottery performed on the condition that the game ball has passed through the normal symbol gate 13, the variation time of the normal symbol corresponding to the lottery result is 29 seconds. And a game state in which the opening control time of the second start port 15 is set to be as short as 0.2 seconds. That is, when the game ball passes through the normal symbol gate 13, the normal symbol is drawn, and the normal symbol display device 22 displays the fluctuation of the normal symbol, but the normal symbol is displayed 29 seconds after the fluctuation display is started. Stop display later. If the lottery result is a win, the second start port 15 is controlled to the second mode for about 0.2 seconds after the normal symbol stop display.

On the other hand, the “short-time gaming state” means that the normal symbol variation time corresponding to the lottery result is 3 seconds in the normal symbol lottery performed on condition that the game ball has passed through the normal symbol gate 13. , A game that is set shorter than the “non-short game state”, and the opening control time of the second start port 15 when winning in the win is 3.5 seconds, which is set longer than the “non-short game state” State. Furthermore, in the “non-short-time gaming state”, the probability of winning in the normal symbol lottery is set to 1/65536, and in the “short-time gaming state”, the probability of winning in the normal symbol lottery is set to 65535/65536. Is set. At this time, the short-time game flag, which will be described later, is set in the short-time game state, and the short-time game flag is off in the non-short-time game state.
Therefore, in the “short-time gaming state”, the second starting port 15 is more easily controlled to the second mode as long as the game ball passes through the normal symbol gate 13 than in the “non-short-time gaming state”. Thereby, in the “short-time gaming state”, the player can advance the game without consuming the game ball.
In addition, since the normal symbol gate 13 is provided in the second dedicated area consisting only of the second game area 6R, in the “short-time game state”, the operation handle 3 is largely rotated to increase the firing strength. A game ball is fired to play a game.
Note that the probability of winning in the normal symbol lottery may be set so that it does not change in any of the “non-short-time gaming state” and the “time-short gaming state”.

  Next, the progress of the game in the gaming machine 1 will be described using a flowchart.

(Main processing of main control board)
The main process of the main control board 110 will be described with reference to FIG.

  When power is supplied from the power supply board 170, a system reset occurs in the main CPU 110a, and the main CPU 110a performs the following main processing.

  First, in step S10, the main CPU 110a performs an initialization process. In this process, the main CPU 110a reads a startup program from the main ROM 110b and initializes a flag stored in the main RAM 110c in response to power-on.

  In step S20, the main CPU 110a performs an effect random number update process for updating the reach determination random value and the special figure variation random value for determining the variation mode (variation time) of the special symbol.

  In step S30, the main CPU 110a updates the initial random number value for special symbol determination, the initial random number value for big hit symbol, the initial random number value for small bonus symbol, and the initial random number value for normal symbol determination. Thereafter, the processes of step S20 and step S30 are repeated until a predetermined interrupt process is performed.

(Timer interrupt processing of main control board)
The timer interrupt process of the main control board 110 will be described with reference to FIG.

  A clock pulse is generated every predetermined period (4 milliseconds) by the reset clock pulse generation circuit provided on the main control board 110, thereby executing a timer interrupt process described below.

  First, in step S100, the main CPU 110a saves the information stored in the register of the main CPU 110a to the stack area.

  In step S110, the main CPU 110a updates the special symbol time counter, updates the special game timer counter such as the opening time of the special electric accessory, updates the normal symbol time counter, and updates the normal power release time counter. A time control process for updating various timer counters is performed. Specifically, a process of subtracting 1 from a special symbol time counter, a special game timer counter, a normal symbol time counter, and a general electricity open time counter is performed.

In step S120, the main CPU 110a performs a random number update process for the special symbol determination random number value, the big hit symbol random number value, the small hit symbol random number value, and the normal symbol determination random number value.
Specifically, each random number value and random number counter are updated by adding +1. When the added random number counter exceeds the maximum value in the random number range (when the random number counter makes one revolution), the random number counter is returned to 0, and each random number value is newly updated from the initial random number value at that time. .

  In step S130, as in step S30, the main CPU 110a updates the initial random number value for special symbol determination, the initial random number value for big hit symbol, the initial random number value for small hit symbol, and the initial random number value for normal symbol determination. Perform numerical value update processing.

In step S200, the main CPU 110a performs input control processing.
In this process, the main CPU 110a includes a general winning opening detection switch 12a, a first large winning opening detection switch 16a, a second large winning opening detection switch 17a, a first starting opening detection switch 14a, a second starting opening detection switch 15a, a gate. An input process for determining whether or not there is an input to each switch of the detection switch 13a is performed.

  Specifically, various detection signals from the general winning opening detecting switch 12a, the first big winning opening detecting switch 16a, the second large winning opening detecting switch 17a, the first starting opening detecting switch 14a, and the second starting opening detecting switch 15a. Is inputted, predetermined data is added to the prize ball counter used for the prize ball provided for each prize opening and updated.

  Furthermore, when a detection signal is input from the first start port detection switch 14a, if the data set in the first special symbol hold number (U1) storage area is less than 4, the first special symbol hold number ( U1) Add 1 to the storage area to obtain special symbol determination random number value, jackpot symbol random number value, small hit symbol random number value, reach determination random value, and special symbol variation random value The random number value is stored in a predetermined storage unit (0th storage unit to 4th storage unit) in the first special symbol random value storage area.

  Similarly, when a detection signal is input from the second start port detection switch 15a, if the data set in the second special symbol hold number (U2) storage area is less than 4, the second special symbol hold number (U2) 1 is added to the storage area, and a special symbol determination random number value, a big hit symbol random number value, a small hit symbol random number value, a reach determination random number value, and a special symbol variation random value are acquired. Various random numbers are stored in a predetermined storage unit (0th storage unit to 4th storage unit) in the second special symbol random number value storage area.

  When a detection signal is input from the gate detection switch 13a, if the data set in the normal symbol hold number (G) storage area is less than 4, the normal symbol hold number (G) storage area is set to 1. It adds, acquires the random number value for normal symbol determination, and memorize | stores the acquired random number value for normal symbol determination in the predetermined memory | storage part (0th memory | storage part-4th memory | storage part) in a normal symbol holding | maintenance storage area.

  Further, when a detection signal is input from the first grand prize opening detection switch 16a or the second big prize opening detection switch 17a, the number of game balls won in the first big prize opening 16 or the second big prize opening 17 is counted. 1 is added to the number of entries (C) storage area for the big winning opening to update.

  In step S300, the main CPU 110a performs a special drawing special electric control process for controlling the jackpot lottery, the special electric accessory, and the gaming state. Details will be described later with reference to FIG.

In step S400, the main CPU 110a performs a normal / normal power control process for controlling the normal symbol lottery and the normal electric accessory.
Specifically, it is first determined whether or not one or more data is set in the normal symbol hold count (G) storage area, and one or more data must be set in the normal symbol hold count (G) storage area. If this is the case, the current ordinary power transmission control process is terminated.
If 1 or more data is set in the normal symbol holding number (G) storage area, after subtracting 1 from the value stored in the normal symbol holding number (G) storage area, the data is in the normal symbol holding storage area. The normal symbol determination random numbers stored in the first storage unit to the fourth storage unit are shifted to the previous storage unit. At this time, the normal symbol determination random value already written in the 0th storage unit is overwritten and erased.
Then, referring to the hit determination table shown in FIG. 7B, whether or not the normal symbol determination random number value stored in the 0th storage unit of the normal symbol hold storage area is a random value corresponding to “win”. Processing to determine is performed. Thereafter, the normal symbol display device 22 displays the fluctuation of the normal symbol. When the fluctuation time of the normal symbol elapses, the normal symbol corresponding to the result of the normal symbol lottery is stopped and displayed. If the random number for normal symbol determination referred to is “winning”, the start opening / closing solenoid 15c is driven to control the second start opening 15 to the second mode for a predetermined opening time.
Here, in the non-short-time gaming state, the variation time of the normal symbol is set to 29 seconds, and if it is “winning”, the second start port 15 is controlled to the second mode for 0.2 seconds. On the other hand, in the short-time gaming state, the normal symbol variation time is set to 0.2 seconds, and if it is “winning”, the second start port 15 is controlled to the second mode for 3.5 seconds. .

In step S500, the main CPU 110a performs a payout control process.
In this payout control process, the main CPU 110a refers to each prize ball counter, generates payout number designation commands corresponding to various winning ports, and transmits the generated payout number designation commands to the payout control board 130. To do.

In step S700, the main CPU 110a performs output control processing. In this process, a port output process is performed for outputting signals of the external information data, the start opening / closing solenoid data, the first big prize opening / closing solenoid data, and the second big prize opening / closing solenoid data created in S600.
Further, the special symbol display device data and the normal symbol display device data created in S600 are used to turn on the LEDs of the first special symbol display device 20, the second special symbol display device 21 and the normal symbol display device 22. Display device output processing is performed.
Further, command transmission processing for transmitting the command set in the effect transmission data storage area of the main RAM 110c to the effect control board 120 is also performed.

  In step S800, the main CPU 110a restores the information saved in step S100 to the register of the main CPU 110a.

(Special figure special electric control processing of main control board)
With reference to FIG. 11, the special figure special power control process of the main control board 110 will be described.

First, in step S301, the value of the special figure special electricity processing data is loaded, the branch address is referred to from the special figure special electric treatment data loaded in step S302, and if the special figure special electric treatment data = 0, the special symbol memory determination process (step The process proceeds to S310). If the special symbol special power processing data = 1, the process proceeds to the special symbol variation processing (step S320). If the special symbol special power processing data = 2, the special symbol stop processing (step S330) is performed. If special figure special electric processing data = 3, the process moves to jackpot game processing (step S340), and if special figure special electric processing data = 4, the process moves to big hit game end processing (step S350). If special electric processing data = 5, the process moves to the small hit game ending process (step S360).
This “special drawing special electricity processing data” is set as necessary in each subroutine of the special figure special electricity control processing as will be described later, so that the subroutine necessary for the game is appropriately processed. .

In the special symbol memory determination process in step S310, the main CPU 110a performs a jackpot determination process, a special symbol determination process for determining a special symbol to be stopped and displayed, a variation time determination process for determining a variation time of the special symbol, and the like.
Here, the specific content of the special symbol memory determination process will be described with reference to FIG.

(Special symbol memory judgment processing of the main control board)
FIG. 12 is a diagram showing a special symbol memory determination process of the main control board 110.

First, in step S311, the main CPU 110a determines whether one or more data is set in the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area.
If one or more data is not set in any storage area of the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area, the special figure special electricity processing data = 0. The special symbol variation process of this time is terminated while holding.
On the other hand, if one or more data is set in the first special symbol hold count (U1) storage area or the second special symbol hold count (U2) storage area, the process proceeds to step S312.

In step S312, the main CPU 110a performs a jackpot determination process.
Specifically, when one or more data is set in the second special symbol hold count (U2) storage area, 1 is calculated from the value stored in the second special symbol hold count (U2) storage area. After the subtraction, the various random numbers stored in the first to fourth storage units in the second special symbol random number storage area are shifted to the previous storage unit. At this time, various random values already written in the 0th storage unit are overwritten and deleted. Then, with reference to the jackpot determination table shown in FIG. 7 (a-2), the random number for special symbol determination stored in the 0th storage unit of the second special symbol random number storage area corresponds to “big hit”. It is determined whether it is a numerical value or a random value corresponding to “small hit”.
In addition, when one or more data is not set in the second special symbol hold number (U2) storage area and one or more data is set in the first special symbol hold number (U1) storage area, Various random numbers stored in the first to fourth storage units in the first special symbol random number storage area after subtracting 1 from the value stored in the first special symbol hold number (U1) storage area Is shifted to the previous storage unit. Also at this time, various random numbers already written in the 0th storage section are overwritten and deleted. Then, with reference to the jackpot determination table shown in FIG. 7 (a-1), the random number value for special symbol determination stored in the 0th storage unit of the first special symbol random number storage area corresponds to “big hit”. It is determined whether it is a numerical value or a random value corresponding to “small hit”.
In the present embodiment, the random number value stored in the second special symbol random value storage area is shifted (digested) with priority over the first special symbol random value storage area. However, the first special symbol storage area or the second special symbol storage area may be shifted in the order of winning in the starting opening, and the first special symbol storage area is given priority over the second special symbol storage area. You may let them.

In step S313, the main CPU 110a performs a special symbol determination process for determining the type of special symbol to be stopped and displayed.
In this special symbol determination process, when it is determined as “big hit” in the jackpot determination process (step S312), the first special symbol random value storage area is referred to with reference to the symbol determination table shown in FIG. The jackpot symbol (special symbol 1 to special symbol 6) is determined based on the random number value for the jackpot symbol stored in the 0th storage unit. In addition, when it is determined as “small hit” in the big hit determination process (step S312), the 0th memory of the first special symbol random value storage area is referred to with reference to the symbol determination table shown in FIG. 8B. The small hit symbol (special symbol A, special symbol B) is determined based on the random number value for the small bonus symbol stored in the section. If it is determined that the game has been determined to be “lost” in the jackpot determination process (step S312), the lost symbol (special symbol 0) is determined with reference to the symbol determination table shown in FIG.
Then, stop symbol data corresponding to the determined special symbol is stored in the stop symbol data storage area.

In step S314, the main CPU 110a performs special symbol variation time determination processing.
Specifically, the variation pattern of the special symbol is determined based on the reach determination random number value and the special diagram variation random value stored in the 0th storage unit of the first special symbol random value storage area. Thereafter, the variation time of the special symbol corresponding to the determined variation pattern of the special symbol is determined. Then, a process of setting a counter corresponding to the determined variation time of the special symbol in the special symbol time counter is performed.

In step S315, the main CPU 110a sets, in a predetermined processing area, variation display data for causing the first special symbol display device 20 or the second special symbol display device 21 to perform special symbol variation display (LED blinking). . As a result, when the variable display data is set in the predetermined processing area, the LED lighting / extinguishing data is appropriately created in step S600, and the created data is output in step S700. Variation display of the special symbol display device 20 or the second special symbol display device 21 is performed.
Further, the main CPU 110a, when the special symbol variation display is started, the special symbol variation pattern designation command (the first special symbol variation pattern designation command) corresponding to the special symbol variation pattern determined in step S314. Alternatively, the second special symbol variation pattern designation command) is set in the effect transmission data storage area of the main RAM 110c.

  In step S316, the main CPU 110a sets the special symbol special electricity processing data = 0 to the special symbol special electric treatment data = 1, prepares to move to the special symbol variation processing subroutine, and ends the special symbol memory determination processing.

The description of the special figure special electric control process shown in FIG. 11 will be returned.
In the special symbol variation process of step S320, the main CPU 110a performs a process of determining whether or not the special symbol variation time has elapsed.
Specifically, it is determined whether or not the variation time of the special symbol determined in step S314 has elapsed (special symbol time counter = 0), and if it is determined that the variation time of the special symbol has not elapsed The special symbol variation process is terminated while the special symbol special electricity processing data = 1 is held. Note that the special symbol variation time counter set in step S314 is subtracted in step S110.
If it is determined that the variation time of the special symbol has elapsed, the special symbol determined in step S313 is stopped and displayed on the first special symbol display device 20 or the second special symbol display device 21. Thereby, the special symbol is stopped and displayed on the first special symbol display device 20 or the second special symbol display device 21, and the player is notified of the jackpot determination result.
Also, when the number of time reduction (J)> 0, 1 is subtracted from the time reduction (J) counter and updated. When the number of time reduction (J) = 0, the time reduction game flag is cleared and the number of high probability games (X )> 0 is updated by subtracting 1 from the high probability game number (X) counter, and if the high probability game number (X) = 0, the high probability game flag is cleared.
Finally, the special symbol special power processing data = 1 is set to the special symbol special power processing data = 2, preparation is made to move to a special symbol stop processing subroutine, and the special symbol variation processing is terminated.

In the special symbol stop process in step S330, the main CPU 110a performs a process of determining whether the special symbol that is stopped and displayed is a “big hit symbol”, a “small bonus symbol”, or a “losing symbol”. Do.
If it is determined that the game is a jackpot symbol, the data stored in the gaming state storage area is referred to and data (00H to 03H) indicating the current gaming state is set in the gaming state buffer. Thereafter, the data (high probability game flag and short time game flag), high probability game number (X) counter, and short time number (J) counter stored in the high probability game flag storage area and the short time game flag storage area are cleared. . Further, the special figure special power processing data = 2 is set to the special figure special electric processing data = 3, preparation is made to move to the jackpot game processing subroutine, and the special symbol stop processing is ended.
In addition, when it is determined that the small winning symbol, the data stored in the game state storage area is not cleared, and the special figure special electric processing data = 2 to the special figure special electric treatment data = 5 is set. The special symbol stop process is completed by making preparations for transferring to a winning game process subroutine.
On the other hand, if it is determined that the symbol is a lost symbol, the special symbol special electric processing data = 2 is set to special special electric symbol processing data = 0, and the special symbol memory determination processing subroutine is prepared for the special symbol stop processing. finish.

In the jackpot game process of step S340, the main CPU 110a determines which jackpot of the long hit or short hit is executed, and performs a process of controlling the determined jackpot.
Specifically, the jackpot release mode is determined based on the type of jackpot symbol (stop symbol data) determined in step S313.
Next, in order to execute the determined jackpot opening mode, an opening time corresponding to the type of jackpot is set in the special game timer counter, and the first big winning opening opening / closing solenoid 16c (or the second big winning opening opening / closing solenoid) is set. 17c) is output to open the first big prize opening / closing door 16b (or the second big prize opening / closing door 17b). At this time, 1 is added to the round game count (R) storage area.
When a predetermined number of game balls enter during the opening or when the opening time of the big prize opening has elapsed (the number of the big prize opening (C) = 9 or the special game timer counter = 0), The output of the drive data of the big prize opening / closing solenoid 16c (or the second big prize opening / closing solenoid 17c) is stopped, and the first big prize opening / closing door 16b (or the second big prize opening / closing door 17b) is closed. Thereby, one round game is completed. This round game control is repeated 15 times.
When the 15 round games are completed (round game count (R) = 15), the data stored in the round game count (R) storage area and the number of winning prize entrance (C) storage areas are cleared, The special figure special electric processing data = 3 is set to the special figure special electric treatment data = 4, preparation is made to move to the big hit game end processing subroutine, and the big hit game processing is ended.

In the big hit game ending process in step S350, the main CPU 110a determines either the high probability game state or the low probability game state, and the game state of either the short-time game state or the non-short-time game state. Perform the decision process.
Specifically, based on the data stored in the game state buffer and the type of jackpot symbol (stop symbol data) determined in step S313, the setting of the high probability game flag, the number of high probability games (X) , Time-short game flag, time-short number of times (J). For example, in the case of the special symbol 1, the high probability game flag is set in the high probability game flag storage area, and the high probability game number (X) counter is set to 10,000 times. Further, a time-short game flag is set in the time-short game flag storage area, and a time-short time (J) counter is set to 10,000 times.
After that, the special symbol special power processing data = 4 is set to the special symbol special power processing data = 0, and preparation for moving to the special symbol memory determination processing subroutine is made, and the big hit game end processing is ended.

In the small hit game processing in step S360, the main CPU 110a determines the small hit release mode based on the type of small hit symbol (stop symbol data) determined in step S313.
Next, in order to execute the determined small winning opening mode, the small winning opening time is set in the special game timer counter, and the driving data of the second large winning opening / closing solenoid 17c is output to output the second large winning opening. The open / close door 17b is opened. At this time, 1 is added to the number-of-releases (K) storage area.
When the small winning opening time elapses (special game timer counter = 0), the drive data output of the second big prize opening / closing solenoid 17c is stopped and the second big prize opening / closing door 17b is closed. The opening / closing control of the second big prize opening opening / closing door 17b is repeated 15 times.
Then, the opening / closing control of the second grand prize opening / closing door 17b is performed 15 times, or a predetermined number of game balls enter the second big prize opening 17 (the number of times of opening (K) = 15 or the grand prize opening entrance) Number (C) = 9), in order to end the small hit game, the output of the drive data of the second large winning opening / closing solenoid 17c is stopped, the number of times of opening (K) storage area and the number of winning winning holes (C) Clear the data stored in the storage area, set special figure special electricity processing data = 5 to special figure special electricity treatment data = 0, and prepare to move to a special symbol memory judgment processing subroutine. The winning game process is terminated.

  Next, processing executed by the sub CPU 120a in the effect control board 120 will be described.

(Production control board main processing)
The main process of the effect control board 120 will be described with reference to FIG.

  In step S1000, the sub CPU 120a performs an initialization process. In this process, the sub CPU 120a reads the main processing program from the sub ROM 120b and initializes and sets a flag stored in the sub RAM 120c in response to power-on. If this process ends, the process moves to a step S1400.

  In step S1100, the sub CPU 120a performs an effect random number update process. In this process, the sub CPU 120a performs a process of updating random numbers (effect random number value, effect design determining random value, effect mode determining random value, etc.) stored in the sub RAM 120c. Thereafter, the process of step S1100 is repeated until a predetermined interrupt process is performed.

(Timer interrupt processing of production control board)
The timer interrupt process of the effect control board 120 will be described with reference to FIG.
Although not shown in the figure, a clock pulse is generated every predetermined period (2 milliseconds) by a reset clock pulse generation circuit provided on the effect control board 120, a timer interrupt processing program is read, and the timer of the effect control board is read. Interrupt processing is executed.

  First, in step S1400, the sub CPU 120a saves the information stored in the register of the sub CPU 120a to the stack area.

  In step S1500, the sub CPU 120a performs update processing of various timer counters used in the effect control board 120.

In step S1600, the sub CPU 120a performs a command analysis process for analyzing the command received from the main control board 110. In this command analysis process, the sub CPU 120a performs a process of analyzing a command stored in the reception buffer of the sub RAM 120c.
For example, if the received command is a variation pattern designation command, one random effect value is acquired from the effect random number value updated in step 1100, and one variation effect pattern is obtained based on the acquired effect random number value. The determined variation effect pattern is set in the effect pattern storage area, and information on the determined variation effect pattern is transmitted to the image control board 150 and the lamp control board 140. Therefore, the effect pattern based on the determined variation effect pattern The instruction command is set in the transmission buffer of the sub RAM 120c. Further, if the received command is a production symbol designation command, the production symbol designation command is analyzed and production symbol data constituting a combination of the production symbols 36 is determined according to the presence / absence of jackpot and the type of jackpot. In order to set the effect symbol data in the effect symbol storage area and transmit the effect symbol data to the image control board 150 and the lamp control board 140, a stop symbol instruction command indicating the effect symbol data is set in the transmission buffer of the sub RAM 120c. . Thus, necessary data is determined as appropriate according to the content of the received command, and necessary data (effect instruction command) is transmitted to the image control board 150 and the lamp control board 140 as appropriate.

  In step S1700, the sub CPU 120a checks the signal of the effect button detection switch 35a, and performs effect input control processing related to the effect button 35.

  In step S1800, the sub CPU 120a performs data output processing for transmitting various commands set in the transmission buffer of the sub RAM 120c to the lamp control board 140 and the image control board 150.

  In step S1900, the sub CPU 120a restores the information saved in step S1810 to the register of the sub CPU 120a.

  Next, processing executed by the host CPU 150a in the image control board 150 will be described.

(Main processing of image control board)
The main process of the image control board 150 will be described with reference to FIG.
When power is supplied from the power supply board 170, a system reset occurs in the host CPU 150a, and the host CPU 150a performs the following main processing.

  In step S2001, the host CPU 150a performs an interrupt prohibition process. Thus, even if a predetermined interrupt signal (timer interrupt signal, command reception interrupt signal, etc.) is input, the input interrupt signal can be ignored and the processes of steps S2001 to S2007 described below can be executed.

In step S2002, the host CPU 150a creates a checksum for each predetermined address range (1000000H) of the CGROM 151, and stores the created checksums in a predetermined storage area of the host RAM 150b.
Specifically, the host CPU 150a creates a “first checksum” in the address range of 0000000H to 0FFFFFFH of the CGROM 151, and stores the created first checksum in a predetermined storage area of the host RAM 150b. . Similarly, the host CPU 150a creates a “second checksum” in the address range of CGROM 151 from 1000000H to 1FFFFFFH, and creates a “third checksum” in the range of addresses from 2000000H to 2FFFFFFH of CGROM151. Then, the “fourth checksum” in the address range of 3000000H to 3FFFFFFH of CGROM 151 is created, and the “fifth checksum” in the range of address address of 4000000H to 4FFFFFFH of CGROM 151 is created. The thumb is stored in a predetermined storage area of the host RAM 150b (see FIG. 6).

In step S2003, the host CPU 150a loads the predetermined checksum data, which are normal values of the first to fifth checksums, from the predetermined storage area of the host ROM 150c.
Specifically, the host CPU 150a loads symbol checksum data (for example, “1234”) from a predetermined address address in the range of 20000H to 20FFFFFH in the host ROM 150c. Similarly, the host CPU 150a loads character checksum data (for example, “2345”) from a predetermined address address in the range of 2100000H to 21FFFFFH in the host ROM 150c, and determines in advance in the range of 2200000H to 22FFFFFH in the host ROM 150c. The background checksum data (for example, “3456”) is loaded from the specified address address, and the movie checksum data (for example, “4567”) is loaded from the predetermined address address in the range of 2300000H to 23FFFFFH in the host ROM 150c. Pallet checksum data (for example, “5678”) from a predetermined address in the range of 2400000H to 24FFFFFH in the host ROM 150c. ) To load (see FIG. 6).

In step S2004, the host CPU 150a compares the checksum created in step S2002 with the checksum data loaded in step S2003, and determines whether all the created checksums are normal. To do.
Specifically, the first checksum and the design checksum data are compared, the second checksum and the character checksum data are compared, and the third checksum and the background checksum are compared. The fourth checksum and the movie checksum data are compared, and the fifth checksum and the palette checksum data are compared.
If all the created checksums are normal, the process proceeds to step S2007. If all the created checksums are not normal, the process proceeds to step S2005.

  In step S2005, if any of the created checksums is abnormal (if the checksum created in step S2002 does not match the checksum data loaded in step S2003), the host CPU 150a The address address range of the CGROM 151 in which the abnormal data is stored is specified.

In step S2006, the host CPU 150a displays, on the liquid crystal display device 31, a specific image for indicating the range of address addresses of the CGROM 151 in which abnormal data is stored, based on the range of address addresses of the CGROM 151 specified in step S2005. An instruction to display is given to VDP2000. By this processing, as will be described later with reference to FIG. 16, it is possible to specify a data error of the CGROM 151 and an address range of abnormal data.
After step S2006, the interrupt permission process is not performed, and an infinite loop state is established. For this reason, unless the data of the CGROM 151 is restored (the CGROM 151 is replaced) and the power is turned on, a specific image indicating the address range of the CGROM 151 in which abnormal data is stored is continuously displayed. However, the control process of the one-chip microcomputer 110m on the main control board 110 is continuously executed regardless of the display.

In step S2007, the host CPU 150a performs initial setting processing around the host CPU 150a. In this initial setting process, the host CPU 150a instructs initial setting of various modules of the host CPU 150a and VDP2000.
Here, the host CPU 150a instructs the liquid crystal display device 31 to display an initial image for power-on (such as a color bar or a character image “power-on”) as an instruction for initial setting of the VDP 2000, An instruction to store high image data (image data such as the production symbol 36) in the frame buffer of the VRAM 153 in advance is given.

  In step S2008, the host CPU 150a performs an interrupt permission process in order to permit the process by the predetermined interrupt signal prohibited in step S2001.

In step S2009, if the effect instruction command from the effect control board 120 is stored in the reception buffer of the host RAM 150b, the host CPU 150a reads the effect instruction command, analyzes the read effect instruction command, and creates an animation pattern. Perform the animation pattern decision process.
Note that when the effect instruction command is read from the reception buffer of the host RAM 150b, the read effect instruction command is deleted from the reception buffer of the host RAM 150b.

In step S2010, the host CPU 150a performs an animation control process.
In this animation control process, first, the addresses of various animation scenes are updated based on the animation pattern determined in step S2009 and a frame counter described later. Next, based on the animation scene information at the updated address, a display list including drawing control command groups is generated. When the generation of the display list is completed, the host CPU 150a outputs the display list to the VDP 2000.

In step S2011, the host CPU 150a determines whether or not the previous drawing has been completed. Specifically, it is determined whether a drawing end interrupt signal is input from VDP2000.
If the previous drawing has been completed, the host CPU 150a moves the process to step S2070. If the previous drawing has not been completed, the host CPU 150a waits until the previous drawing is completed.

  As described above, the process from step S2009 to step S2011 is repeated until the predetermined interrupt signal is input and the process by the predetermined interrupt signal is performed.

In addition to the main process of the image control board 150 shown in FIG. 15, there is an interrupt process that is executed by inputting a predetermined interrupt signal.
In particular, in this embodiment, when the host CPU 150a inputs a V blank interrupt signal output every 1/60 seconds (about 16.6 ms) from the VDP 2000, the host CPU 150a includes a V blank interrupt process for updating the frame counter. ing.

  The VDP 2000 draws the image data stored in the CGROM 151 in the frame buffer of the VRAM 153 based on an instruction (display list input) from the host CPU 150a, and also outputs a video signal from the image data drawn in the frame buffer of the VRAM 153. (RGB signal or the like) is generated and output to the liquid crystal display device 31.

(Checksum error display method)
Next, a checksum error display method will be described with reference to FIG.

  FIG. 16 shows the range of address addresses of CGROM 151 in which abnormal data is stored when sprite data (symbol data) in the address range of 0000000H to 0FFFFFFH of CGROM 151 is abnormal. 5 is a diagram showing that a specific image for informing the content is displayed on the liquid crystal display device 31. FIG.

  Here, if the sprite data (symbol data) in the address range of 0000000H to 0FFFFFFH in the CGROM 151 is abnormal, the “first checksum” (see step S2002 in FIG. 15) created by the host CPU 150a is It does not match the checksum data for symbols (see steps S2003 and S2004 in FIG. 15).

  Then, as shown in FIG. 16, the host CPU 150a instructs the VDP 2000 to display on the liquid crystal display device 31 a specific image for indicating the range of address addresses from 0000000H to 0FFFFFFH in the CGROM 151 (see step S2006 in FIG. 15). .

  Based on an instruction to display a specific image from the host CPU 150a, the VDP 2000 starts from a predetermined address address in the address address range from 1000000H to 1FFFFFFH of the CGROM 151, “CGROM error”, “error address”, “0000000H to 0FFFFFFH”, Sprite data (character data) of the characters “(symbol data error)” (hereinafter referred to as “abnormality notification characters”) is drawn in the frame buffer of the VRAM 153. The VDP 2000 generates a video signal (RGB signal or the like) from the image data drawn in the frame buffer of the VRAM 153 and causes the liquid crystal display device 31 to display a specific image.

  As described above, when the sprite data (symbol data) in the address address range of 0000000H to 0FFFFFFH of the CGROM 151 is abnormal, it indicates the range of the address address of the CGROM 151 where the abnormal data is stored and the contents of the abnormal data Can be displayed on the liquid crystal display device 31.

(Modification 1)
In the present embodiment, sprite data (character data) of “abnormality notification character” used in the specific image is provided in the range of the address address where the error is determined by the checksum, but the error is determined by the checksum. You may provide in the range of the address address where no.
In the first modification, the “abnormality notification character” sprite data is provided in a range of address addresses where an error is not determined by a checksum. Modification 1 will be described with reference to FIG.

  In the first modification, as shown in the memory maps of the CGROM 151 and the host ROM 150c in FIG. 17, the sprite data of “abnormality notification character” is stored in the address range of 5000000H to 5FFFFFFH of the CGROM 151. Then, the host CPU 150a does not perform error determination based on the checksum for the address address range of 5000000H to 5FFFFFFH in the CGROM 151.

In this way, the sprite data itself of the “abnormality notification character” is not subject to checksum error determination.
In the first place, even if the sprite data of the “abnormality notification character” is broken, it is possible to continue the effects related to the game. According to the first modification, even if the sprite data of the “abnormality notification character” is broken, the error determination of the sprite data of the “abnormality notification character” is not performed, so that the specific image is continuously displayed on the liquid crystal display device 31. There is nothing. For this reason, even if the sprite data of the “abnormality notification character” is broken, the effects relating to the game can be continued and the operation of the gaming machine is not reduced.

(Other embodiments)
In the present embodiment and the first modification, the sprite data of “abnormality notification character” is stored in the rewritable CGROM 151. However, in addition to the rewritable CGROM 151, a non-rewritable mask ROM is provided, Sprite data of “abnormality notification characters” may be stored in an impossible mask ROM. Further, sprite data of “abnormality notification character” may be stored in the non-rewritable host ROM 150c.
As a result, the sprite data of the “abnormality notification character” is broken in the first place, and although it is determined as an error by the checksum, the address range of the CGROM 151 storing the abnormal data and the content of the abnormal data cannot be notified. And can solve the problem.

  Moreover, according to this embodiment, although the game machine used for a pachinko game machine was demonstrated, you may use for a swing type game machine (slot machine), a jigball game machine, and an arrangement ball game machine.
