In addition, an antenna for wireless communication unit 16 to wirelessly communicate with another game apparatus 10 is formed on a substrate inside the housing and is not exposed outside the housing.

  FIG. 2 shows a block diagram of the game apparatus 10. The game machine 12 includes a processor 40, which includes a CPU core 42, a boot ROM 44, an LCD controller 46, a working RAM (WRAM) 48, a video RAM (VRAM) 50, and peripheral circuits 52 associated with the CPU core 42. However, the peripheral circuit 52 includes a sound (sound) circuit, a DMA (Direct Memory Access) circuit, a timer circuit, an input / output interface (IO), and the like.

  The processor 40 gives a display signal to the LCD 24, in this embodiment, an RGB signal, so that the game image is displayed in color on the LCD 24. Further, the processor 40 outputs an audio signal to the audio amplifier 54, and sounds such as game music and sound effects are output from the speaker 28 by the audio signal. An operation signal from the operation switch 26 is input to the processor 40. Therefore, the processor 40 executes processing in accordance with the operation instruction of the user or player given through the operation switch 26.

  The cartridge 20 includes a ROM 32 and a backup RAM 34. In the ROM 32, a game program and data for a game to be executed by the game machine 12 are stored in advance together with the game name (game program identification information) and the like. The backup RAM 34 is used for storing mid-game data and game result data, and such game data is rewritable and stored in a nonvolatile manner via the connector 18. The backup RAM 34 may be configured with a flash memory or the like.

  When the power of the game machine 12 is turned on, the CPU core 42 executes a boot program stored in the boot ROM 44 and performs a boot process of the game machine 12. Thereafter, the CPU core 42 executes the game program stored in the ROM 32 of the cartridge 20 and executes the game process while storing the temporary data generated by the execution in the WRAM 48 that can be written and read. The image data generated by the CPU core 42 executing the game program is drawn (stored) in the VRAM 50, and the image data stored in the VRAM 50 is output to the LCD 24 by the LCD controller 46. Further, the CPU core 42 generates transmission data to other game devices in a predetermined area of the WRAM 48 and outputs the data to the wireless communication unit 16 via the communication connector 14. The received data received from the other game apparatus 10 via the wireless communication unit 16 is processed by the CPU core 42 and temporarily stored in a predetermined area of the WRAM 48.

  The wireless communication unit 16 is a communication unit that communicates with another game apparatus 10 by, for example, short-range wireless communication, and includes a base band IC 56. The baseband IC 56 includes a ROM (not shown). The ROM contains, for example, an OCD (One-Cartridge Download) program and other programs, and the baseband IC 56 operates according to these programs.

  The one-cartridge download program is an OC mode (one-cartridge mode: a mode in which a game cartridge is attached only to the master unit, and the slave unit operates by receiving a slave unit program and data downloaded from the master unit cartridge. ), A program for downloading a program or the like to the slave unit.

  The wireless communication unit 16 is further provided with an EEPROM 58, and for example, the own device ID and the player name input by the user are uniquely stored in the EEPROM 58. The baseband IC 56 encodes data (program, game data, etc.) transferred from the game machine 12 via the communication connector 14 and the connector 30, data including the player name of the EEPROM 58, etc., and generates RF (Radio Frequency). ) -Send to IC60. The RF-IC 60 modulates the data and transmits a radio wave from the antenna 62. However, the radio wave intensity is very weak, and is set to a value that is small enough to be used unlicensed by the user in the Radio Law. The wireless communication unit 16 is provided with a power supply circuit 64. The power supply circuit 64 is typically a battery and supplies DC power to each component of the wireless communication unit 16.

  In the wireless communication unit 16, the radio wave transmitted from the other portable game apparatus 10 is received by the antenna 62 and demodulated by the RF-IC 60, and the demodulated signal is input to the baseband IC 56. Therefore, the baseband IC 56 decodes the demodulated signal, restores the data, and transfers the data to the game machine 12, that is, the WRAM 48 via the connector 40 and the communication connector 14.

  This game system includes a plurality of game devices 10 as described above. One of the plurality of game devices 10 serves as a parent device, and the other game devices serve as child devices. That is, the game system includes a parent device (first game device) and at least one child device (second game device).

  FIG. 3 shows an outline of a communication procedure between the game apparatuses 10 in this game system. In the example of FIG. 3, the game system includes three game devices 10a, 10b, and 10c. The game device 10a is a parent device, and the other game devices 10b and 10c are child devices. Note that the wireless communication connection between the parent device 10a and each of the child devices 10b and 10c is established prior to the communication game process.

  As shown in FIG. 3, when a game process for progressing a communication game is performed, first, the communication state between the parent device and each child device is confirmed. That is, first, the parent device transmits transmission confirmation data for confirming the communication state to one child device (10b) a predetermined number of times (for example, 100 times). That is, the parent device transmits a predetermined number of transmission confirmation data to the child device. When receiving the transmission confirmation data from the parent device, the child device transmits the same number of reception confirmation data as the number of received transmission confirmation data to the parent device. For example, when the slave unit receives the transmission confirmation data 100 times, the slave unit transmits the reception confirmation data to the master unit 100 times. The transmission confirmation data is transmitted from the parent device a predetermined number of times, but there is also transmission confirmation data that is not received by the child device depending on the communication state. In such a case, a smaller number of reception confirmation data than the predetermined number of transmission confirmation data transmitted by the parent device is transmitted from the child device. Then, the master unit receives the reception confirmation data from the slave unit and detects the number of received reception confirmation data (the number of receptions). Since there is also reception confirmation data that is not received by the parent device depending on the communication state, the number of reception confirmation data may be smaller than the number transmitted from the child device. Subsequently, the master unit similarly performs the confirmation process of the communication state for the other slave units (10c), and detects the number of receptions with the other slave units.

  After the number of receptions is detected, substantial communication game processing is executed between the parent device and each child device. Specifically, the parent device changes the game process according to the number of receptions detected between each child device. In addition, the parent device transmits communication data including the number of receptions or information set based on the number of receptions or game processing results to each child device. Each slave unit transmits communication data including data necessary for the game process to the master unit, and changes the game process according to the received number of receptions.

  The detected number of receptions indicates the communication state between the game devices, and reflects the distance (positional relationship) between the parent device and each child device. In other words, communication errors are relatively less likely to occur if the distance between the parent device and the child device is shorter, so the number of detected receptions increases, and conversely, if the distance between the parent device and the child device is far, communication errors occur relatively. Since it is easy, the number of receptions detected becomes small. Therefore, in this game system, game processing is executed in accordance with the communication state between game devices, that is, the actual positional relationship between the players. Further, since the number of receptions can be detected by simply counting the number of reception confirmation data received, it is possible to detect a communication state between game devices with a simple process.

  In this way, the detection of the number of receptions between the parent device and each child device and the game processing based on the number of receptions in the parent device or each child device are repeated every predetermined number of frames or every frame. As a result, the game proceeds. When the number of receptions corresponding to each child device changes, game processing is executed according to the changed number of receptions.

  In this game system, as an example, a communication game is performed in which items are exchanged between a parent device and a child device. In this case, the parent device changes the priority of the communication game with each child device in accordance with the number of receptions, and determines the communication order so that the ranking is higher in the order of the number of receptions, for example. Therefore, since the communication rank with each game device 10 can be changed according to the number of receptions detected with each game device 10, a highly interesting communication game can be provided. Then, the master unit transmits communication data including information on the determined communication priority order to each slave unit, and executes a game process corresponding to the communication order. On the other hand, each child device changes the game process according to the received priority order. In addition, when the number of receptions detected with each child device changes as the game progresses, the communication priority with each child device changes according to the changed number of receptions. The corresponding game process is executed.

  Further, for example, a communication game in which the player characters of each player appear in the game space is performed. In this case, the master unit transmits communication data including information on the number of receptions to each slave unit. Further, the master unit changes the size of each player character corresponding to each slave unit according to the number of receptions with each slave unit. For example, the smaller the reception number, the smaller the size. Further, each child device changes the game process according to, for example, the number of receptions related to the own device, and reduces the size of the player character corresponding to the parent device, for example, as the number of receptions decreases. Therefore, since the size of the player character displayed on the screen is changed according to the number of receptions, the game content can be changed according to the number of receptions.

  Further, the master unit outputs a sound such as game music (BGM) changed according to the number of receptions. In addition, each slave unit outputs a sound such as BGM that is changed in accordance with the number of receptions related to its own unit. Therefore, the player can easily know the quality of the communication state of his / her game device 10 by the sound such as the output BGM.

  FIG. 4 shows an example of a memory map of the ROM 32 of the cartridge 20. The ROM 32 includes a program storage area 70, an image data storage area 72, and a sound data storage area 74.

For example, each slave unit is ranked in descending order of the detected number of receptions. Therefore, the priority of communication can be changed according to the number of receptions with each child device, so that it is possible to enhance the fun of the game.

  In the character size determination program storage area 84, the size of the player character displayed on the screen is determined based on the number of receptions in a game in which a plurality of player characters corresponding to each game device 10 appear in the virtual game space. The program for storing is stored. With this program, the master unit determines the size of at least one of the player characters corresponding to each slave unit or the player character corresponding to its own unit based on the number of receptions with each slave unit, for example. To do. In addition, the slave unit is, for example, at least one of a player character corresponding to the master unit and a player character corresponding to the host unit or another unit based on the number of receptions detected by the master unit with the host unit or another unit. Determine the size of one. Specifically, the smaller the number of receptions, the smaller the size of the player character corresponding to the child device or the parent device on the game screen. The size of the player character may be determined using, for example, table data including the size data of the player character associated with the value of the reception number, or the reception number based on the size of the player character of the own device. It may be calculated according to the value of. This program can change the sense of distance from each player character in the virtual game space according to whether the communication state of the opponent player with the game apparatus 10 is good or not, and can enhance the fun of the game.

  The character drawing program storage area 86 stores a program for drawing a character image. By this program, an image of each player character having a size determined based on the number of receptions and an image of another character (such as an enemy character) are drawn.

  The sound data change program storage area 88 stores a program for changing sound data according to the number of receptions. By this program, the sound data of sounds such as game music or BGM to be output is changed according to the number of receptions. For example, the master unit determines sound data to be used for output from a plurality of BGMs based on the total or average value of the number of receptions with each slave unit or the maximum or minimum number of receptions. On the other hand, in the slave unit, for example, sound data to be used for output is determined from among a plurality of BGMs based on the number of receptions detected by the master unit with respect to the slave unit. Alternatively, in the master unit and the slave unit, the content of the sound data to be output may be changed based on the number of receptions, for example, by changing or increasing / decreasing tracks to be reproduced or changing the timbre. Good. Therefore, the player can easily know whether the communication state between the game apparatuses 10 is good or not by the output sound.

  Although not shown in the program storage area 70, there are various programs necessary for the progress of the game, such as a program for displaying a drawn image on the LCD 24 and a program for outputting sound from the speaker 28. It is remembered.

  The image data storage area 72 stores image data for generating a game screen, such as player character image data, possessed item image data, enemy character image data, background image data, and the like. The CPU core 42 draws a game image on the VRAM 50 based on this image data.

  The sound data storage area 74 stores a plurality of sound data for outputting sounds such as game music (BGM), sound effects or sounds, such as BGM data and sound effect data. The CPU core 42 uses a sound circuit or the like to generate an audio signal to be output based on the sound data or the like.

  FIG. 7 shows an example of a game screen displayed on the child device of the player 3 who is waiting for the communication game with the parent device. The game screen of FIG. 7 corresponds to the game screen of FIG. In other words, the communication priority of the child machine of the player 3 is the third place, and no communication game is performed with the parent machine. A priority display unit 108 provided in the lower right part of the screen in FIG. 7 displays the communication priority of the slave unit. In the center of the screen, a message indicating that the communication game is waiting is displayed with characters or designs such as “Waiting for communication. Please wait for a while”. Information related to priority is transmitted from the parent device. As described above, the player of the game apparatus 10 that is not in the highest communication order knows that the communication game with the parent machine is not being performed, and communicates with the game apparatus 10 of the player as compared with the game apparatus 10 of other players. It is possible to know how good the state is.

  FIG. 9 shows an example of the contents of communication data (referred to as “parent communication data”) transmitted from the parent device. The parent communication data is transmitted to each child device after the parent device determines the communication order based on the number of receptions. The parent communication data in FIG. 9 includes communication priority data indicating information related to the communication priority. In the communication priority data, the communication priority of each child device connected to the parent device is set. Each slave unit obtains its own priority from the received communication priority data and displays it on the rank display unit 108 in the game screen.

  FIG. 10 shows an example of the operation of the communication game process during the item exchange game of the parent device in this game system. In the first step S 1 of FIG. 10, the CPU core 42 of the parent device sets an initial value “1” for the variable N. Next, in step S3, the CPU core 42 transmits transmission confirmation data for confirming the communication state to the Nth child device through the wireless communication unit 16 a predetermined number of times. Subsequently, in step S <b> 5, the CPU core 42 receives the reception confirmation data from the N-th slave device that is the other party that transmitted the transmission confirmation data via the wireless communication unit 16. In step S 7, the CPU core 42 detects the number of reception confirmation data received from the Nth slave unit received in step S 5, and stores the detected reception number in a predetermined area of the WRAM 48. Are stored in association with each other.

  In step S9, the CPU core 42 determines whether or not the value of the variable N is equal to, for example, the maximum number of child devices. The maximum number of slave units is the number of slave units that are connected to the master unit by wireless communication. That is, in step S9, it is determined whether or not the detection of the number of receptions with all the slave units has been completed. If “NO” in the step S9, the CPU core 42 adds “1” to the variable N in a succeeding step S11, and returns to the step S3.

  On the other hand, if “YES” in the step S9, the CPU core 42 determines a communication priority order with respect to each child device based on the number of receptions detected with each child device in a step S13. Subsequently, in step S15, the CPU core 42 executes processing for displaying the communication priority with each slave unit. As a result, for example, as shown in FIG. 5, an image of the game screen on which the communication order with each child device is displayed on the order display unit 100 is drawn on the VRAM 50, and the game screen is displayed on the LCD 24 by the LCD controller 46. .

  In step S17, the CPU core 42 creates parent communication data. As a result, for example, parent communication data including communication priorities of each child device as shown in FIG. 9 is created. Then, in the next step S <b> 19 in FIG. 11, the CPU core 42 transmits parent communication data to each child device via the wireless communication unit 16.

  Subsequently, in step S21, the CPU core 42 determines whether or not there is a child device currently in communication. If "YES" in this step S21, the CPU core 42 executes an item exchange process with the currently communicating slave unit. On the other hand, if “NO” in the step S21, the CPU core 42 executes an item exchange process with the child device having the highest communication priority based on the communication priority determined in the step S13. In the item exchange process of the parent machine, operation input data from the operation switch 26 of the parent machine is acquired, and communication data including data necessary for game progress is transmitted to the child machine in the communication game. Then, for example, as shown in FIG. 5, a game screen showing the state of item exchange based on the operation input data of the parent device and the communication data from the child device is generated in the VRAM 50 and displayed on the LCD 24.

  In the subsequent step S27, the CPU core 42 determines whether or not the communication with the currently communicating slave unit has ended. For example, when the exchange of items with the slave unit is completed, or when the end of the item exchange is instructed by the operation of a predetermined operation switch 26 by the player, it is determined that the communication is terminated. If “NO” in the step S27, that is, if the communication with the slave unit is continued, the process returns to the step S1 in FIG. 10 to repeat the process.

  On the other hand, if “YES” in the step S27, the CPU core 42 determines whether or not there is a slave unit waiting for communication in a succeeding step S29. If “YES” in this step S29, that is, if there is a child device whose communication priority is not first, the process returns to step S1 in FIG. 10 to repeat the processing. On the other hand, if “NO” in the step S29, the communication game process is ended.

  FIG. 12 shows an example of the operation of the communication game process at the time of the item exchange game of the handset in this game system. In the first step S41 in FIG. 12, the CPU core 42 of the slave unit receives transmission confirmation data from the master unit via the wireless communication unit 16. Since the parent device transmits a predetermined number of transmission confirmation data, the child device receives the transmission confirmation data transmitted from the parent device and detects the number of received transmission confirmation data.

  Next, in step S43, the CPU core 42 transmits the same number of reception confirmation data as the number of received transmission confirmation data to the parent device via the wireless communication unit 16.

  Subsequently, in step S45, the CPU core 42 receives parent communication data transmitted from the parent device. The parent communication data from the parent device includes priority data of each child device as shown in FIG.

  In step S47, the CPU core 42 executes processing for displaying the communication priority of the own device based on the received parent communication data. As a result, for example, as shown in FIG. 6 or FIG. 7, an image of the game screen on which the communication order of the slave units is displayed on the order display unit 108 is drawn on the VRAM 50. Is done.

  In step S49, the CPU core 42 determines whether to communicate with the parent device. That is, for example, it is determined whether or not the communication priority of the own device is the first, or whether or not the own device is communicating with the parent device. If “YES” in the step S49, that is, if a communication game is performed with the parent device, the CPU core 42 executes a communication process with the parent device, that is, an item exchange process, in a step S51. . In this process, operation input data from the operation switch 26 of the child device is acquired, and communication data including data necessary for the game progress is transmitted to the parent device. Then, for example, as shown in FIG. 6, a game screen showing the state of item exchange based on the operation input data of the slave unit and the communication data from the master unit is generated in the VRAM 50 and displayed on the LCD 24.

  On the other hand, if “NO” in the step S49, that is, if a communication game with the parent device cannot be performed, the CPU core 42 executes a communication waiting display process in a step S53. By this process, for example, as shown in FIG. 7, a game screen indicating that the communication is waiting is generated in the VRAM 50 and displayed on the LCD 24.

  Subsequently, in step S55, the CPU core 42 determines whether or not the communication with the parent device is finished. For example, for example, when the exchange of items with the parent machine is completed, or when the end of item exchange with the parent machine is instructed by the operation of a predetermined operation switch 26 by the player, the communication is terminated. It is judged. If “NO” in the step S55, that is, if communication with the parent device is continued, the process returns to the step S41 to repeat the process. On the other hand, if “YES” in the step S55, the communication game process is ended.

  FIG. 13 shows an example of a game screen displayed on the parent machine when playing a battle game with this game system. In the example of FIG. 13, the game system includes two game apparatuses 10, the parent machine is operated by the player 1, and the child machine is operated by the player 2.

Information relating to the position of the player character PC2 of the slave unit is transmitted from the slave unit. In this embodiment, in the master unit, the size of the player character corresponding to each slave unit is changed based on the number of receptions with each slave unit. For example, the size of the player character of the child device displayed on the screen is reduced as the number of receptions is decreased, and is increased so as to approach the size of the player character PC1 of the own device as the number of receptions is increased.

  Further, in the game screen of the child device of FIG. 14, the player character PC2 corresponding to the own device is displayed in the approximate center of the screen, and the player character PC1 corresponding to the parent device that is the communication partner is displayed on the left side of the screen. In this embodiment, in the child machine, the size of the player character PC1 corresponding to the parent machine is changed based on the number of receptions with the parent machine. For example, the size of the base player character PC1 displayed on the screen is reduced as the number of receptions is decreased, and is increased so as to approach the size of the player character PC2 of the own device as the number of receptions is increased. Information on the position of the player character PC1 of the parent machine and information on the number of receptions of the child machines are transmitted from the parent machine.

  In FIG. 15 showing the actual positional relationship of the players, players 1 and 2 are indicated by reference signs P1 and P2, and a circle indicated by a broken line indicates a communicable area of the base unit of player 1. As can be seen from FIG. 15, the distance between the player characters on the game screens shown in FIGS. 13 and 14 reflects the actual distance between the master player 1 and the slave player 2. That is, as shown in FIG. 15, since the player 1 and the player 2 exist relatively apart from each other, a game screen is displayed in which each player character appears to exist relatively far apart in the virtual game space. Is done.

  Further, although not represented in the game screens of FIGS. 13 and 14, the output sound is changed based on the number of receptions in the parent device and each child device. For example, in the master unit, the BGM sound data to be output is changed based on the detected number of receptions from each slave unit. In the slave unit, the BGM sound data to be output is changed based on the number of receptions corresponding to the own unit transmitted from the master unit. Therefore, different BGMs are output according to the actual distance or positional relationship between players.

  FIG. 16A shows an example of the content of communication data (referred to as “child communication data”) transmitted from the child device to the parent device. The child communication data includes position data in the game space of the player character (i-th player character) of the own device (i-th child device) (i is a positive integer). Based on the position data included in the received child communication data, the parent device determines the position of the i-th player character corresponding to the i-th child device in the game space of the parent device.

  FIG. 16B shows an example of the content of parent communication data transmitted from the parent device to each child device. The parent communication data includes position data and reception number data. The position data includes information regarding the positions in the game space of the player character of the parent machine and each player character of each child machine. The reception number data includes information regarding the reception number between each child device detected by the parent device. Each slave unit determines the position of each slave unit in the game space of each player character based on the received position data. In each child device, the size of the player character of the parent device or the player character of the other child device and the output BGM are changed based on the received number data corresponding to the received own device or other child devices. .

  FIG. 17 shows an example of the operation of the communication game process during the battle game of the parent machine in this game system. In step S71 to step S81 in FIG. 17, the CPU core 42 of the parent device executes processing for detecting the number of receptions from each child device. Since the processes in steps S71 to S81 are the same as the processes in steps S1 to S11 in FIG. 10, detailed description thereof is omitted here.

  If “YES” in the step S79, in a subsequent step S83, the CPU core 42 determines the size of the player character of each child device based on the number of receptions detected with each child device. In step S85, the CPU core 42 changes the sound data of the BGM to be output based on the number of receptions detected with each slave unit.

  Subsequently, in step S 87, the CPU core 42 receives the child communication data transmitted from each child device via the wireless communication unit 16 and stores it in a predetermined area of the WRAM 48. As shown in FIG. 16A, the child communication data includes position data of the player character of the child machine.

Specifically, the CPU core 42 determines the size of each player character determined in step S83, the position of the player character of each child device determined in step S89, the position of the player character of the own device determined in step S93, and the like. Based on this, each player character is arranged in the game space, and an image of a game space in a predetermined range including the player character of the player, that is, a game screen, is drawn on the VRAM 50 using each image data in the image data storage area 72. To do. In step S <b> 101, the CPU core 42 displays the drawn game screen on the LCD 24 using the LCD controller 46.

  Subsequently, in step S103, the CPU core 42 executes BGM output processing. Specifically, the CPU core 42 generates an audio signal based on the BGM data obtained in step S85, outputs the audio signal to the audio amplifier 54, and outputs the sound of the BGM from the speaker 28.

  In step S105, the CPU core 42 determines whether or not the game is over. For example, it is determined whether or not the player character of the own device has been defeated, whether or not all other player characters have been defeated, or whether or not the operation input data of the own device is an instruction to end the game. If “NO” in the step S105, that is, if the game is continued, the process returns to the step S71 in FIG. 17 to repeat the process. On the other hand, if “YES” in the step S105, the communication game process is ended.

  FIG. 19 shows an example of the operation of the communication game process during the battle game of the slave unit in this game system. The processing in step S121 and step S123 in FIG. 19 is the same as the processing in step S41 and step S43 in FIG. 12, and thus detailed description thereof is omitted here.

  In step S125, the CPU core 42 determines whether or not there has been an operation input or key input from the operation switch 26 of the own machine. If “YES” in the step S125, the CPU core 42 determines the position of the player character of the own machine based on the acquired operation input data in a step S127. On the other hand, if “NO” in the step S125, the process proceeds to a step S129 as it is.

  In step S129, the CPU core 42 creates child communication data including the position data of the player character of the own machine as shown in FIG. In subsequent step S131, the CPU core 42 transmits the child communication data to the parent device via the wireless communication unit 16.

  In step S 133, the CPU core 42 receives the parent communication data via the wireless communication unit 16 and stores it in a predetermined area of the WRAM 48. As shown in FIG. 16B, the parent communication data includes position data of each player character and reception number data between each child device detected by the parent device.

  In the next step S135 of FIG. 20, the CPU core 42 determines the size of the player character of the parent machine based on the received number data corresponding to the own machine acquired from the parent communication data. When there are a plurality of slave units, in this process, based on the reception number data corresponding to each other slave unit acquired from the parent communication data, each player character corresponding to each other slave unit is processed. The size may be determined.

  Subsequently, in step S137, the CPU core 42 determines the position of each player character other than the own machine based on the position data of each player character acquired from the parent communication data.

  In step S139, the CPU core 42 executes a drawing process for each player character. Specifically, the CPU core 42 determines the size of the player character of the parent machine determined in step S135, the position of the player character of the own machine determined in step S127, and the player character other than the own machine determined in step S137. Based on the position and the like, each player character is arranged in the game space, and an image of a predetermined range of the game space including the player character of the player, that is, a game screen, is obtained using each image data in the image data storage area 72. Draw in the VRAM 50. In step S <b> 141, the CPU core 42 displays the drawn game screen on the LCD 24 using the LCD controller 46.

  In step S143, the CPU core 42 changes the sound data of BGM to be output based on the reception number data corresponding to the own device acquired from the parent communication data. Subsequently, in step S145, the CPU core 42 executes BGM output processing. Specifically, the CPU core 42 generates an audio signal based on the BGM data obtained in step S143, provides the audio signal to the audio amplifier 54, and outputs the BGM sound from the speaker 28.

  In step S147, the CPU core 42 determines whether or not the game is over. For example, it is determined whether or not the player character of the own device has been defeated, whether or not all other player characters have been defeated, or whether or not the operation input data of the own device is an instruction to end the game.
