Description

  The present invention relates to a game program and a game apparatus for checking fraud of predetermined data used in a game.

  2. Description of the Related Art Conventionally, with respect to a game played using a game device, a so-called cheat action that illegally alters data related to items or characters used in the game may be performed. For example, the status (experience value, physical fitness value, etc.) of a character appearing in a game may be changed to an illegal value that is not assumed in the game. For this reason, some game devices or game programs have a function of checking the presence or absence of illegal data subjected to such a cheat action (see Patent Documents 1 to 3).

  Among these, in Patent Documents 1 and 3, when illegal data is detected by checking, the illegal data is discarded so that it cannot be used, and only normal data for which illegality is not detected by checking is used. It is disclosed to advance the game. Also, in Patent Document 2, a player who operates a game device having illegal data is going to participate in an online multiplayer game in which a plurality of game devices are communicably connected and a game is advanced by a plurality of players. , Prohibiting the participation of the player is disclosed.

Japanese Patent No. 3619220 JP 2006-81609 A JP 2008-272487 A

  However, from the standpoint of other players, as described above, the illegal data is uniformly discarded and cannot be used or the participation of the game device having the illegal data in the online game is uniformly prohibited. It is not necessarily an appropriate process.

  More specifically, in the case of the former, in a multiplayer game in recent years, a character (non-player) that the player cannot directly control the movement to a player character whose movement is directly controlled by the player. Some characters can be accompanied by a character). In such a game, a place (lobby) where the participating player characters and non-player characters meet together is set in the virtual space set in the game, and the characters gathered here participate in the game. It is displayed on the display of each game device. Here, for example, in the state where each character is meeting the lobby, if it is determined that the data related to any non-player character is illegal, according to the techniques disclosed in Patent Documents 1 and 3, Unauthorized non-player character data is discarded and use is prohibited. As a result, the character displayed on the display of each game device is suddenly deleted due to fraud detection, or it is not possible to participate in the game despite being displayed. This may cause discomfort to other players.

  In the case of the latter, there is a case where a player who operates a game device having the illegal game data thinks that there is no problem in participating in an online game even if the use of illegal data is not allowed from a legitimate player. is there. Therefore, even in such a case, it is difficult to say that prohibiting participation sufficiently meets the needs of legitimate players.

The game data transmission means may be configured to be able to transmit correction data obtained by correcting the game data.

  The predetermined game data may be at least a part of player history information that is a play history of the game by a player using the computer.

  Further, the computer is further caused to function as character control means for controlling the movement of the character in the virtual game space in which the game progresses, and the predetermined game data includes status data indicating the status of the character. Also good.

  The illegal data processing means is configured to correct the numerical value to a predetermined numerical value within the range when the illegal data includes a numerical value outside a preset normal range. May be.

  Further, when the illegal data includes a pre-registered prohibited character string, the illegal data processing means converts the prohibited character string into a predetermined character string that does not include the registered prohibited character string. You may be comprised so that it may correct.

  The game program according to the present invention is a game progress means for causing a computer to advance a predetermined game in response to an operation input from a player, and predetermined game data used in the game is permitted in the game. Fraud determination means for determining whether it is regular data that is assumed in advance or illegal data that is not supposed; illegal data that processes the illegal data when it is determined that the data is illegal And functioning as a processing means and a game situation acquisition means for obtaining a game situation. When the illegal data processing means determines that the data is illegal data, the game situation acquisition means obtains the game situation acquisition means according to the game situation acquired by the game situation acquisition means. The processing contents of the illegal data are switched.

  In addition, for the character having the control right that can be controlled by the other computer, the computer receives copy data from the other computer that can be copied to a state in which the computer can have the control right. The duplicate data is included in the predetermined game data, and the illegal data processing means is configured to receive the duplicate data when the received duplicate data is illegal data. The use of the character may be prohibited.

  In addition, a copy that transmits to the other computer copy data that can be copied to a state in which the computer can have the control right for the character having the control right that can control the operation of the computer. Further, the predetermined game data includes the duplicate data, and the illegal data processing means, when the duplicate data to be transmitted is illegal data, The transmission may be prohibited.

Of these, the CPU 11, the drawing data generation processor 12, the RAM 13, the ROM 14, the drawing processing processor 15, the voice processing processor 18, the operation unit 22, the media interface 23, and the wireless LAN module 24 can mutually transmit data via the bus 25. It is connected to the.

  The operation unit 22 includes direction keys and other button groups (not shown), receives an operation by the player, and inputs an operation signal corresponding to the operation content to the CPU 11. In addition, various buttons included in the direction key and the button group are operators for instructing a specific action of the player character. The operation unit 22 includes a power switch for turning on / off the game machine 1 in addition to these operators.

  The media interface 23 accesses the game media 5 set in a media mounting unit (not shown) and reads the game program 5a and the game data 5b. Among these, the game program 5a causes the game apparatus 1 to execute an action game having a content in which a player character and an enemy character battle each other in a virtual game space. The game data 5b includes data necessary for executing the game, such as character and background image data, image data for displaying information such as status, sound data such as sound effects and BGM, characters and symbols. Message data etc. are included. The game media 5 that is a storage medium can employ a UMD (Universal Media Disc) (registered trademark), which is a kind of optical disc, in addition to a semiconductor memory, and in this embodiment, the recorded contents can be overwritten. Although a recording medium is employed, when a recording medium that cannot be overwritten is employed as the game medium 5, another overwritable recording medium may be provided so as to be accessible from the control unit 30.

  In the RAM 13, a load area for storing the game program 5a and game data 5b read from the game media 5 according to the progress of the game, and a work area for use when the CPU 11 processes the game program 5a are set. Has been. The ROM 14 stores a basic function of the game apparatus 1 such as a disk loading function, and a basic program for controlling the reading process of the game program 5a and game data 5b stored in the game media 5.

  The CPU 11 reads all or part of the game program 5a and game data 5b recorded in the game media 5 into the RAM 13 through the media interface 23, and executes them in accordance with the operation of the operation unit 22 by the player. To control. More specifically, when an operation signal is input from the operation unit 22 by being operated by the player, the CPU 11 performs a predetermined game progress process corresponding to the operation signal in accordance with the game program 5a, and displays the processing result. An image indicating the progress of the game (hereinafter referred to as “game image”) is displayed on the display 2 and a sound signal indicating the progress of the game (hereinafter referred to as “game sound”) is output to the speaker 20 and the earphone terminal 21.

  Drawing of the game image is performed by the drawing processor 15 in accordance with an instruction from the CPU 11. That is, the CPU 11 determines the content of the game image to be displayed on the display 2 based on the operation signal input from the operation unit 22 and causes the drawing data generation processor 12 to generate necessary drawing data for the content. Then, the drawing data is transferred to the drawing processor 15 to perform drawing processing. The drawing processor 15 generates a game image every 1/60 seconds based on the drawing data, and writes the generated game image in the VRAM 16. The display 2 has a transflective color liquid crystal display and a backlight LED (Light Emitting Diode), and displays a game image written in the VRAM 16.

  Further, the CPU 11 determines sound effects such as sound effects and BGM to be output from the speaker 20 in accordance with the progress of the game, reads out sound data for generating the sound from the RAM 13 and inputs the sound data to the sound processor 18. . That is, when a sound generation event occurs with the progress of the game, the CPU 11 reads out sound data corresponding to the sound generation event (voice data loaded from the game media 5) from the RAM 13 and inputs it to the sound processing processor 18. The audio processor 18 is constituted by a DSP (Digital Signal Processor), and after giving a predetermined effect (for example, reverb, chorus, etc.) to the audio data input by the CPU 11, it is converted into an analog signal, Output to the amplifier 19. The amplifier 19 amplifies the audio signal input from the audio processor 18 and then outputs it to the speaker 20 and the earphone terminal 21.

  The wireless LAN module 24 performs data communication with other game devices 1 by a wireless LAN compliant with the communication standard IEEE802.11b (used frequency band 2.4 GHz, communication speed 11 Mbps), and configures an ad hoc mode network NW. It is a communication module. Therefore, as shown in FIG. 1, the game apparatuses 1 can communicate with each other via the network NW, and transmit / receive predetermined game data or advance a multiplayer game in synchronization as will be described later. Be able to.

[Game system]
Next, an outline of a game system that can be played by the game apparatus 1 by executing the game program 5a will be described. FIG. 2 is a schematic diagram for explaining an aspect of the game system. A system of a multiplayer game in which players operating a plurality of game devices 1 recognize each other and advance the game together. FIG. In this embodiment, a so-called hunting action game is illustrated in which a player performs a mission that causes a player character to act in a virtual game space and subjugate enemy characters such as monsters. Moreover, although the following description illustrates the case where two game apparatuses 1 participate in the multiplayer game, the same applies to the case where three or more game apparatuses 1 participate.

  As shown in FIG. 2, in this game, a player character C1 is set for each game device 1, and at the discretion of the player, a companion character C2 that accompanies the player character C1 and assists in the game is added. It can be set. In this game, a player card C3 in which information for introducing the player is described is set. The player card C3 is a virtual card that can be displayed in the form of a card on the display 2 of the game apparatus 1. The player card C3 includes a history of the game played by the player (play time, completed mission name). Etc.), and player data including editable information (name, self-introduction sentence, etc.) for introducing the player himself is displayed.

  The player character C1 is a character that can directly control the movement in the virtual game space by operating the operation unit 22 by the player. In this game, the player character C1 is a hunter. Become. The accompanying character C2 and the enemy character are non-player characters whose movement cannot be directly controlled by the operation of the operation unit 22 by the player, and the CPU 11 controls the movement according to the situation.

  Further additional description regarding the accompanying character C2, the accompanying character C2 is a non-player character that can be set for each game device 1 by registration by the player. The accompanying character C2 registered by the player is only the game device 1. You will have control. Here, the “control authority” related to the accompanying character C2 means the authority that the control unit 30 can control the operation of the accompanying character C2 as the game progresses. The accompanying character C2 grows by participating in the mission accompanied by the player character C1, and the parameters (experience value etc.) included in the status data are within a normal range predetermined for the accompanying character C2. ) Will change.

  Further, the data (including status data) related to the accompanying character C2 is a part of player history information indicating the history of the game played by the player, and the data is registered by registering (setting) the accompanying character C2. Recorded in the RAM 13 of the game apparatus 1. Then, it is recorded (saved) in the game media 5 or other accessible recording medium by a predetermined operation by the player thereafter.

  In this game, by operating the game device 1 and setting it to a predetermined mode (hereinafter also referred to as “multiplayer mode”), the wireless LAN module 24 is connected to another game device 1 set to the same mode. Thus, a network NW that can communicate with each other is constructed. Then, through this network NW, a multiplayer game can be played in which players operating each game device 1 cooperate with each other to advance the same mission synchronously.

  More specifically, the player character C1 and the accompanying character C2 of each game apparatus 1 set in the multiplayer mode are collected in a lobby (meeting place) L set in the virtual game space. The characters C1 and C2 gathered in the lobby L, including those operated by other players, are all displayed on the display 2 of each game device 1 (in the example of FIG. 2, the display 2A of the game devices 1A and 1B, 2B). Then, when a predetermined time has passed since the first characters C1 and C2 entered the lobby L, when the maximum number of characters that can participate is gathered, or by satisfying other predetermined conditions, A mission that all the collected characters C1 and C2 perform together in a common virtual game space is started.

  Note that the game apparatus 1 can register a plurality of accompanying characters C2, and has the above-described control right for each of the registered accompanying characters C2. Further, the player can select (determine) the accompanying character C2 to be accompanied with the mission from the list indicating the registered accompanying character C2. Thus, by selecting the accompanying character C2 to be accompanied by the mission, the selected accompanying character C2 is displayed in the lobby L as shown in FIG. 2 shows a state in which the player character C1 has selected one accompanying character C2, but in this embodiment, up to two accompanying characters C2 are selected for one game apparatus 1. be able to. Therefore, when two accompanying characters C2 are selected, two accompanying characters C2 are displayed in the lobby L with respect to the player character C1.

  Here, only the original game apparatus 1 in which each character C1 is set has the operation right that can control the movement of each character C1 in the multiplayer game in accordance with the operation of the player. That is, in the example of FIG. 2, the game apparatus 1A has the operation right of the character C1-A set on the game apparatus 1A, and the operation right of the character C1-B set on the game apparatus 1B is the game The apparatus 1B has. Therefore, for example, the character C1-B is also displayed on the display 2A of the game apparatus 1A, but this cannot be operated by the game apparatus 1A, and only the game apparatus 1B can be operated. And when it operates with game device 1B and character C1-B is operated, the mode of operation will be displayed not only on game device 1B but on display 2A of game device 1A.

  Further, as described above, the control right of each accompanying character C2 belongs to the game apparatus 1 in which it is registered. That is, in the example of FIG. 2, only the game apparatus 1A has the control right of the accompanying character C2-A, and only the game apparatus 1B has the control right of the accompanying character C2-B. Therefore, for example, the accompanying character C2-B is also displayed on the display 2A of the game apparatus 1A, but the operation of the accompanying character C2-B cannot be controlled by the game apparatus 1A, and only the game apparatus 1B can Operation control can be performed. When the accompanying characters C2-A and C2-B move with the progress of the game, the operation mode is displayed on the displays 2A and 2B on both the game apparatuses 1A and 1B.

  In this way, in order for the game device 1 to display the character C1 having the operation right and the accompanying character C2 having the control right on the other game devices 1, the statuses of the characters C1 and C2 between the game devices 1 are displayed. The above-described status data indicating is transmitted / received. This status data includes names set for the characters C1 and C2 by the player, weapons and armor equipped, experience values acquired according to previous play histories, levels, attack power, and the like. . Therefore, by receiving status data from other game devices 1 (by temporarily recording them in the RAM 13 of each game device 1), for example, each character C1, C2 has the same appearance on all game devices 1. Can be displayed. Note that, for example, the player character C1-A for which the game apparatus 1A has an operation right is displayed on the display 2B of the game apparatus 1B because the data is erased from the RAM 13 of the game apparatus 1B when the multiplayer game ends. Disappear. Also, the accompanying character C2-A for which the game apparatus 1A has the control right is erased from the RAM 13 of the game apparatus 1B when the multiplayer game is finished, so that it is not displayed on the display 2B of the game apparatus 1B. .

  On the other hand, regarding the player card C3, only the original game device 1 to which the player card C3 is set has the ownership and editing rights. The “ownership” relating to the player card C3 referred to here owns the data so that the player card C3 can be browsed even when the game apparatus 1 is offline (that is, the game medium 5 or This means a right that can be recorded (saved) on another accessible recording medium, and “editing right” indicates the display contents of the player card C3 (that is, the contents of the recorded (saved) player card C3. Data) is the right to edit. In the example of FIG. 2, the game apparatus 1A has the ownership and editing rights of the player card C3-A set in the game apparatus 1A, and the player card C3-B set in the game apparatus 1B. The game apparatus 1B has the right and the editing right.

  When “delivery” or “distribution” described later is performed, the player card C3 of another game device 1 can be displayed on the game device 1 of the own device. In addition, the game device 1 of the own device can save the data (player data) related to the player card C3, and the player card C3 can be browsed even after going offline by saving. . However, regardless of whether it is online or offline, the content (for example, the name of the player, etc.) can be edited only by the game device 1 having the editing right (in the above example, the other game device 1).

  Note that the data related to the player card C3 is also a part of player history information indicating the history of the game played by the player, and the data is recorded in the RAM 13 of the game apparatus 1 by setting or editing the player card C3. . Then, it is recorded (saved) in the game media 5 or other accessible recording medium by a predetermined operation by the player thereafter.

  By the way, in this game, the companion character C2 and the player card C3 can be “delivered” between the plurality of game apparatuses 1 participating in the multiplayer game. That is, in the state where a plurality of players participate in the multiplayer game and the characters C1 and C2 are gathered in the lobby L, a copy of the accompanying character C2 is copied to the other game apparatus 1 (the accompanying character C2 has the control right). Can be handed over to other game devices 1 (game devices that do not have ownership and editing rights for the player card C3). You can “deliver”.

  FIG. 3 is a schematic diagram for explaining the “delivery”. As shown in FIG. 3, by performing a predetermined operation on the game apparatus 1A, duplicate data of the accompanying character C2-A for which the game apparatus 1A has the control right is generated, and other games participating in the multiplayer game are generated. It is transmitted to all game devices 1 (game device 1B in FIG. 3). Note that it may be transmitted to only the player (game device 1) designated by the player by a predetermined operation, without being transmitted to all other participating game devices 1. When the game device 1B is operated to receive it by the player, the game device 1B receives the duplicate data. The game apparatus 1B has the control right of the accompanying character C2-A related to the received duplicate data, and is registered as the accompanying character C2 that can be accompanied by the mission. Accordingly, when the accompanying character C2-A is selected as the accompanying character C2 to be accompanied with the mission in the game apparatus 1B, as shown in FIG. 3, the accompanying character C2-A is displayed on the display 2B with the same appearance as the original. In addition, although not shown, it is also displayed on the display 2 of another game apparatus 1 participating in the multiplayer game in the same manner.

  That is, the duplicate data of the accompanying character C2-A is the same accompanying character that the game apparatus 1A has the control right when the game apparatus 1B receiving it records the duplicate data on a recording medium such as the RAM 13. In addition to being able to display C2-A on its own device (game device 1B) even when the game device 1A, 1B is offline, when accompanied by a mission, the accompanying device will be accompanied by the progress of the game. This is data that can be duplicated as a character that can control the movement of the character C2-A. Note that this duplicated data also includes status data indicating the status of the accompanying character C2.

  Further, the duplicate data related to the accompanying character C2 is handled as a part of the player history information of the game apparatus 1 that has received the duplicate data. Accordingly, when the mission is accompanied by the accompanying character C2 related to the duplicate data received by “delivery”, the accompanying character C2 can be grown, and the status data (experience value, etc.) is determined in advance. It varies within the normal range. Then, the duplicate data (including status data) recorded on the recording medium such as the RAM 13 is recorded (saved) on the game medium 5 or other accessible recording medium by a predetermined operation by the player, whereby the game apparatus 1. The duplicated data can be held even after the power is turned off.

  Note that the accompanying character C2-A received by the game device 1B is a copy of the original accompanying character C2-A, and therefore the original accompanying character C2 that the game device 1A that performed the “delivery” originally had the control right. -A does not disappear (data is not erased). That is, the original accompanying character C2-A that the game apparatus 1A has control right and the duplicate accompanying character C2-A that the game apparatus 1B has control right coexist at the same time. It should be noted that by deleting the original accompanying character C2-A of the game apparatus 1A that performed the “delivery” (that is, deleting the data from the recording medium such as the RAM 13), the accompanying character related to the duplicate received by the game apparatus 1B It may be deleted without coexisting with C2-A. In the above description with reference to FIG. 3, the case of “delivering” the companion character C2 accompanying the player character C1 participating in the multiplayer game is illustrated, but the present invention is not limited to this. That is, as already described, in the game apparatus 1 according to the present embodiment, a plurality of accompanying characters C2 can be registered in one game apparatus 1. Therefore, in addition to the accompanying character C2 selected to be accompanied by the mission, other accompanying characters C2 registered in the list can be set as targets to be “delivered” to the other game devices 1.

  The same applies to the “delivery” of the player card C3. As shown in FIG. 3, by performing a predetermined operation on the game apparatus 1A, the player card C3-A that the game apparatus 1A has the ownership and editing rights. Is generated and transmitted to all other game devices 1 participating in the multiplayer game (game device 1B in FIG. 3). In addition, even if it does not transmit with respect to all the other participating game apparatuses 1, you may make it transmit only to the player which the player designated by predetermined | prescribed operation. When the game device 1B is operated to receive it by the player, the game device 1B receives the duplicate data. Then, the game apparatus 1B has the ownership of the player card C3-A related to the received copy data.

  Thus, the duplicate data of the player card C3 is the same as the game apparatus 1B that has received the data records the duplicate data on a recording medium such as the RAM 13 so that the game apparatus 1A has ownership and editing rights. The player card C3-A is duplicated so that even if the game device 1A, 1B goes offline, the player's own device (game device 1B) has the ownership and can be displayed on the display 2 of the player's own device. This is the data that can be made possible. The duplicated data includes player data indicating the contents of the player card C3 described above. Also, regarding the player card C3, the game apparatus 1 that has received it has the ownership, but does not have the editing right. Therefore, in the example described above, the game apparatus 1B can browse the player card C3-A received by “delivery”, but cannot edit the contents. Further, by recording (saving) the duplicated data recorded on the recording medium such as the RAM 13 on the game media 5 or other accessible recording medium, the duplicated data is stored even after the power of the game apparatus 1 is turned off. The point which can be kept is the same as in the case of the accompanying character C2 described above.

  Also in this case, the original player card C3-A originally owned by the game apparatus 1A that has performed "delivery" does not cease to exist, and the original player that the game apparatus 1A has the ownership right does not exist. The card C3-A and the duplicated player card C3-A that the game device 1B has ownership of will coexist at the same time. The original player card C3-A of the game apparatus 1A that has been “delivered” is deleted (that is, the data is deleted from the recording medium such as the RAM 13), whereby the player card relating to the copy received by the game apparatus 1B. It is not necessary to coexist with C3-A.

  FIG. 4 is a schematic diagram illustrating another aspect of the game system. The game apparatus 1 can perform so-called “passing communication (registered trademark)” with another game apparatus 1 using the wireless LAN module 24. That is, by starting a predetermined mode provided in the game apparatus 1 and keeping the game apparatus 1 powered on, the game apparatus 1 becomes capable of “passing communication (registered trademark)”. In this state, for example, if the player carries the game device 1 and passes the vicinity of another game device 1 in which the same mode is activated, the game device 1 can be connected between the two game devices 1 without further operation. Communication is performed automatically. In this game, the “delivery” of the accompanying character C2 or the player card C3 can be performed by this communication.

  In this “distribution”, the copy data of the accompanying character C2 or the player card C3 registered in the list can be transmitted / received to / from another game device 1, and the received game device 1 newly gives the control right of the accompanying character C2. It is the same as the above “delivery” in that it has a new ownership of the player card C3. However, since “distribution” is executed without the player recognizing another player, no operation of the player is required when receiving the duplicate data.

[Functional configuration of control unit]
FIG. 5 is a block diagram illustrating a functional configuration of the control unit 30 included in the game apparatus 1 in order to realize the above-described game system. The control unit 30 has functions as described below by executing the game program 5a and the game data 5b read from the game media 5. That is, as shown in FIG. 5, the control unit 30 includes a game space generation unit 31, a character control unit 32, a game progression unit 33, a status data transmission / reception unit 34, a player data transmission / reception unit 35, a duplicate data transmission / reception unit 36, and a fraud determination unit. 37 and unauthorized data processing means 38 and the like. The status data transmission / reception means 34, the player data transmission / reception means 35, and the duplicate data transmission / reception means 36 constitute a game data transmission / reception means in the game apparatus 1.

  The game space generation means 31 generates a virtual game space (including the lobby L) in which the player character C1 acts. The character control means 32 controls the actions of various characters including the player character C1, the accompanying character C2, and the enemy character in the virtual game space. For example, various actions including movement, attack, and defense of the player character C1 during the battle are controlled in accordance with the operation of the operation unit 22 by the player, and by the accompanying character C2 and the enemy character according to the progress of the game. It also controls various actions such as movement, attack, and defense.

  The game progress means 33 controls the progress of the entire game. For example, in a multiplayer game, the mission is started and advanced in accordance with the operation of the operation unit 22 by the player, and enemy characters appear in the virtual game space in accordance with the location where the player character C1 exists, and are displayed on the display 2. In addition, in the battle between the player character C1 and the accompanying character C2 and the enemy character, various controls necessary for the progress of the game are executed, such as managing the damage received by the other by the other attack. In the progress of this game, various game data are used, but the game progress means 33 progresses the game using not only regular data described later as the game data but also corrected data obtained by correcting illegal data. It is possible.

  The status data transmission / reception means 34 receives status data including names set for the characters C1 and C2, weapons and armor equipped, experience values obtained according to the past play history, level, attack power, and the like. Transmission and reception with other game apparatuses 1 is performed. The player data transmission / reception means 35 stores player data including a history of the player playing the game (play time, completed mission name, etc.) and editable information (name, self-introduction sentence, etc.) for introducing the player himself. Transmission / reception is performed with other game apparatuses 1. As described above, the game apparatus 1 participating in the multi-play game, based on the received status data, displays the character C1 that the other game apparatus 1 has the operation right and the accompanying character C2 that has the control right on its own display 2. Can be displayed. Further, based on the received player data, the player card C3 that the other game apparatus 1 has ownership and editing rights can be displayed on its own display 2.

  The duplicate data transmission / reception means 36 generates duplicate data of the accompanying character C2 and the player card C3, and transmits / receives the duplicate data to / from other game apparatuses 1. As described above, transmission / reception of replicated data is executed in any of the “delivery” described with reference to FIG. 3 and the “distribution” described with reference to FIG. The game apparatus 1 that has received the duplicated data can newly have the control right of the duplicated accompanying character C2 or can have the new ownership of the duplicated player card C3.

  The fraud determination means 37 is, for the predetermined game data used in the game, the regular data that is assumed (set) in advance to be allowed in the game, or is illegal (not set) Judgment (check) of data. The unauthorized data processing unit 38 appropriately processes the unauthorized data when the unauthorized game determination unit 37 determines that the predetermined game data is unauthorized data. As will be described later, the contents of the process include a process for correcting illegal data into predetermined correction data having proper contents, a process for prohibiting transmission of illegal duplicated data, and use of received illegal duplicated data. There is a process (specifically, deletion of received copy data) that prohibits (that is, use of accompanying character C2 or player card C3).

[Illegal judgment and illegal data processing]
Next, aspects of fraud determination and fraud data processing will be described. FIG. 6 is a flowchart showing the flow of operations of fraud determination and fraud data processing in this game. As shown in FIG. 6, in this game, first, it is determined whether or not it is a predetermined fraud determination timing (step S1).
If it is determined that it is not the fraud determination timing (step S1: NO), this step S1 is repeated. If it is determined that it is the fraud determination timing (step S1: YES), whether or not the target data is fraudulent is determined. Is executed (step S2).

  Note that various scenes are set for the fraud determination timing in this game, and the target data for fraud determination is also set according to the fraud determination timing. For details, see FIG. Will be described later. In addition, the fraud determination method is not particularly limited in this game, and a known fraud determination method can be appropriately employed.

  Next, when it is determined that the data is illegal as a result of the fraud determination (step S3: YES), predetermined processing described in detail later with reference to FIG. This is executed (step S4), and the series of processes is terminated. Also, when it is determined that the data is not illegal data (regular data) (step S3: NO), the series of processes is terminated. Note that after the series of processing is completed, the processing from step S1 is executed again.

  Hereinafter, each of the fraud determination timing, the determination target data, and the fraud data processing mentioned in the description of the operation flow will be further described. First, the determination timing and the rough processing policy for illegal data will be described, and then the details of specific correction processing for illegal data will be described.

  FIG. 7 is a chart showing the timing for determining whether or not the game data is fraudulent by the fraud determination means 37, the game data to be determined, and the processing policy for the fraud data. As shown in the upper diagram of FIG. 7, in the multi-play game, (1) the data of the player's own device (entered into the room at the timing when the player's own game device 1 (own device) entered the lobby L in the virtual game space. The status data of the accompanying character C2) is checked. If it is determined that there is fraud, the fraudulent data of the own device is corrected.

  (2) Immediately after the player enters the lobby L, the data of all the game devices 1 including the player (status data of the accompanying character C2 already entered) is checked. That is, by entering the lobby L, status data of each accompanying character C2 is sent from another game apparatus 1 that has already entered the room, so these are also checked. For the illegal data determined to be illegal, the data received by the own device is corrected. (3) When another game apparatus 1 newly enters the room while the player is staying in the lobby L, the status data of the accompanying character C2 that has entered the lobby L from the newly entered game apparatus 1 Will be sent, so check this data. If it is determined that there is fraud, the data received by the own device is corrected.

  In addition, (4) While the player is staying in the lobby L, every time a predetermined time elapses (for example, every 2 seconds), data sent from another game device 1 (accompanied by entering the room) Check the status data of character C2. If it is determined that there is fraud, the data received by the own device is corrected. (5) When leaving the lobby L and starting a mission, the data of all game devices 1 including the own device (status data of all accompanying characters C2 already received) are checked. If it is determined that there is fraud, the fraudulent data of the own device is corrected.

  As shown in the lower diagram of FIG. 7, when performing the above-mentioned “delivery” and “distribution”, (6) the game device 1 on the transmission side has a timing immediately before transmitting the duplicate data, Check the duplicate data to be sent. Then, transmission of copy data determined to be illegal is prohibited. (7) The receiving game device 1 also checks the received duplicate data at the timing immediately after the duplicate data is received. If it is determined that there is fraud, the use of the duplicate data, that is, the use of the accompanying character C2 or the player card C3 by the duplicate data is prohibited.

  Note that in the game device 1 according to the present embodiment, when the duplicate data regarding the player card C3 of another player is received by “delivery” and then communicated again with the game device 1 of the player, the content of the duplicate data is The content of the player data relating to the original player card C3 registered in the game apparatus 1 is automatically updated. Then, the illegal determination of new duplicate data transmitted / received for automatic update is also performed. If it is determined that there is an illegality at this time, the duplicate data may be corrected, or the game on the transmitting side may be corrected. The device 1 may prohibit the transmission of the duplicate data, and the receiving game device 1 may prohibit the use of the duplicate data.

  FIG. 8 is a fraud process reference table schematically showing a database that is referred to when the fraud determination means 37 determines whether or not fraud is present and when fraud data is corrected. 5b is recorded in advance. As shown in FIG. 8, items of status data and duplicated data related to the accompanying character C2 that are checked for fraud at each timing described above include “name”, “comment”, “weapon”, “armor”, There are "experience value", "level", "attack power", etc. The “comment” is data composed of a character string indicating the content of the companion character C2.

  As a criterion for determining whether or not these items are legitimate data, a condition of “not including prohibited character strings” is set for “name” and “comment”. As the prohibited character string, as shown in FIG. 8, a corresponding character string (character string 01, character string 02, etc.) is registered in advance. Therefore, when at least one of these prohibited character strings is included, it is determined as illegal data.

  As for “weapons”, those permitted to be used in this game are registered with numerical IDs (101, 102...). Therefore, this ID is regular data, and an ID that does not match any registered one (that is, a numerical ID outside the normal range) is determined as illegal data. Similarly, “armor” that is permitted to be used in this game is registered by an ID (201, 202...) Represented by a numerical value. Therefore, this ID is regular data, and an ID that does not match any registered one is determined as illegal data.

  For the “experience value”, a regular numerical range (0 to 6000, etc.) preset in the game is registered, and the experience value outside this numerical range is determined as illegal data. Also for “level”, a regular numerical range (1 to 20 or the like) preset in the game is registered, and a level outside this numerical range is determined as illegal data. Further, for “attack power”, a regular numerical range (0 to 350, etc.) preset in this game is registered, and attack power outside this numerical range is determined as illegal data. As for the “attack power”, a regular numerical value corresponding to the level is registered within the regular numerical range. For example, a normal value is registered for each level, such as 10 for level 1 attack power and 50 for level 2 attack power. Further, the “attack power” is set to a value higher than a regular value set according to the level according to the equipped weapon.

  On the other hand, the items of player data and duplicated data related to the player card C3 that are checked for fraud at each timing described above include “name” and “self-introduction”. In both cases, as in the case of the “name” and “comment” of the accompanying character C2, the condition of “not including the prohibited character string” is set as a reference for determining whether or not the data is regular data. Therefore, when at least one of these prohibited character strings is included, it is determined as illegal data.

  Next, the correction process executed by the unauthorized data processing unit 38 in accordance with the unauthorized data processing policy shown in FIG. 7 will be described in detail. As shown in FIG. 8, when it is determined that the “name” of the accompanying character C2 is invalid, a reference character string for a name that does not use a prohibited character string set in advance (for example, “sub character”). Replace with. If it is determined that the “comment” is invalid, the comment is replaced with a reference character string for comment that does not use a prohibited character string (for example, a character string including a plurality of asterisks). Even when it is determined that the “name” and the “self-introduction sentence” in the player card C3 are invalid, the same replacement process as described above is performed.

  On the other hand, if it is determined that the “weapon” is illegal, the weapon is replaced with a reference weapon set in advance within the range of the regular data (for example, a weapon having the smallest additional value for the attack power). If it is determined that the “armor” is illegal, the state is replaced with “no armor”. If it is determined that the “experience value” or “level” is incorrect, it is replaced with the smallest value within the range of the regular data. If it is determined that the “attack power” is illegal, it is replaced with a numerical value corresponding to the level of the accompanying character C2.

  In this game, it is possible to advance the game using not only regular data but also correction data obtained by correction as described above. For example, even when an illegal accompanying character C2 whose “attack power” is abnormally high has entered the lobby L, it is corrected to a value corresponding to the level and participates in the mission. It becomes. Accordingly, when the enemy character is played during the mission, the damage that can be given by the attack on the enemy character is not the damage amount based on the illegal attack power but the damage amount based on the corrected attack power.

  Note that the game data received from each of the game devices 1 from other game devices 1 (including illegal data, if any) is temporarily stored in the load area of the RAM 13, and the corrected data obtained by correcting the illegal data is The illegal data is overwritten in the load area of the RAM 13. When the save operation is performed by the player, the game device 1 stores (saves) the game data related to the regular data or the correction data stored in the RAM 13 in the game media 5 or other accessible recording medium. It has come to be.

  As described above, in this game, the data of the accompanying character C2 used for the game progress that the plurality of game apparatuses 1 participating in the multiplayer game transmit / receive to / from each other (that is, (1) to (5) in FIG. 7). Regarding the status data and player data transmitted and received at the timing, even if it is determined that there is fraud, the data is corrected to a normal range of data (corrected data) without being discarded. Each participating game apparatus 1 can advance the multiplayer game using the correction data in addition to the regular data.

  Therefore, even when the status data of the accompanying character C2 to be newly entered is illegal, it is possible to participate in the game as the accompanying character C2 having the corrected status data without prohibiting the entry. Further, even if the status data of the accompanying character C2 once entering the lobby L is subsequently changed to illegal data, the accompanying character C2 is suddenly deleted from the lobby L or exists in the lobby L. Nevertheless, it is not possible to participate in the mission, and it is possible to continue participating in the game as the accompanying character C2 having the corrected status data. Thereby, it is possible to prevent a change in the number of participating characters that affects the progress of the game due to the act of changing the illegal data.

  “In the present embodiment, the data related to the accompanying character C2 and the player card C3 is exemplified as the target of fraud determination. However, the present invention is not limited to this, and data relating to other characters (eg, player characters) and items is fraudulently determined. In the case of data, the same processing as described above may be performed, or the data may not be related to the player such as an enemy character, and the game progress such as duplicate data at the time of “delivery” The data may not be used for.

  Further, the illegal data correction processing is not limited to the mode shown in FIG. For example, if there are frauds in the “comment” or “self-introduction”, this may be modified so that it is displayed blank, and if there is a fraud in the “armor”, it will be more disadvantageous for an unauthorized player. It is also possible to replace it with something that is easily damaged. Further, when the numerical value is corrected, the present invention is not limited to a mode of correcting to one predetermined correction data. In other words, it may be corrected to data within a normal range that is not determined as illegal data. For example, the content of the corrected data may be determined randomly within the normal range, or the status of the player character C1 (on the game) The level may be determined based on the level or the like.

  In addition, in this game, for example, based on information about the player character C1-A included in the player card C3-A of the game apparatus 1A, a new character imitating the appearance of the player character C1-A is displayed on the game apparatus 1B. It may be generated as a companion character C3 and registered. In this case, the fraud determination and the fraud data processing as described above can be applied to the game data transmitted and received between the game apparatuses 1A and 1B.

  Further, in the present embodiment, when the copy data of the accompanying character C2 including the control right is “delivered” or “distributed”, the copy data of the player card C3 including the ownership is “delivered” or “distributed”. In some cases, transmission and use of duplicate data determined to be fraudulent is prohibited. Thus, in the “delivery” and “distribution” of the accompanying character C2 and the player card C3, which are considered to have no influence on the progress of the game, these cannot be substantially achieved. Therefore, by “passing” and “distributing” illegal copy data, the illegal accompanying character C2 and the player card C3 are operated or displayed on the legitimate game device 1 to prevent the player from feeling uncomfortable. can do.

  In addition, about the timing which performs fraud determination, it is not restricted to the timing shown in FIG. 7, A part of them may be deleted and another timing may be added. Further, in the above description, in the “delivery” and “distribution” of the accompanying character C2, the player is transferred with the control right of the accompanying character C2, and the player in the “delivery” and “distribution” of the player card C3. It was mentioned that it was handed over with ownership of the card C3. However, specific embodiments of the present invention are not limited to this.

  For example, regarding game data to be “delivered” or “distributed”, when the game device 1 on the transmission side has the operation right, the game device 1 on the reception side has the operation right for the game data. Any one or more of control right, ownership right, and editing right may be provided. In addition, when the game device 1 on the transmission side has the right to control the game data, the game device on the reception side also has the right to control the game data. You may make it have any one or more. Eventually, the right acquired by the game device 1 on the receiving side is not limited to an aspect that is the same as or part of the right that the game device 1 on the transmitting side has for the game data. The receiving game device 1 may newly acquire a right that the device 1 did not have for the game data.

  The present invention provides a game program and a game apparatus that can reduce discomfort and discomfort caused by a legitimate player, in particular, by performing more appropriate processing when illegal data is detected in a game. Can do.
