Best Mode for Carrying Out the Invention Embodiments of the present invention will now be described with reference to the drawings. In this embodiment, a video game system will now be described as an example of an entertainment system according to the present invention and incorporating game controllers according to the present invention. The video game system according to the present invention is used in an airplane. As shown in Fig. 1, a video game system 1 for use an airplane incorporates a game controller 10; and a game machine body 16 to which the game controller 10 is connected through cables 15. Also a monitor 26 and a speaker 27 are connected to the game machine body 16. The game controller 10 includes a small-size HDD 13 (2.5'). The HDD 13 drives a HD having a storage capacity of 6 GB. Since a usual game title has a capacity of 500 MB, the HD of the HDD 13 is able to store 10 titles. The recording medium is limited according to the size of the program to be recorded. The recording medium may be another medium, such as a flush disc or a semiconductor recording medium. The foregoing recording medium may be a removable medium. As shown in Fig. 2, the game controller 10, the game machine body 16 and the monitor 26 of the video game system may be disposed in the periphery of a seat 2 in an airplane. For example, a passenger at a seat 21 executes a video game while viewing a monitor 261 such that a game controller 101 is joined to a connector 291 provided for a seat back 282 of the forward seat 22 through the cables 15. The game machine body 16, is joined to a lower portion 30, of the seat 2,. The cable is connected to the connector 29, of the seat back 282 of the forward seat 22 through the seat and the floor. A video output from the game machine body 161 and an input to the game controller 10, are supplied to the monitor 261 of the front seat 22 and the connector 291 disposed at the side of the monitor 26,. Note that the seat back 281 of the seat 21 is provided with a monitor 260 for a passenger in the rearward seat (not shown). A game controller 100 is joined to the connector 290. A game machine body 162 for a passenger who takes the seat 22 is joined to the lower portion of the seat 22 As shown in Figs. 1 and 3, the game controller 10 incorporates an operation surface 31 provided with buttons, such as a switch 11, and including an I/O controller 12, a 2.5-inch HDD 13 and an HIDE (Enhanced IDE) interface 14. The I/O controller 12 is joined to the operation surface 31 of the game controller 10. Information items of the switch 11 and so forth are collectively interfaced with the game machine body 16. The EIDE interface 14 serves as an interface with the 2.5-inch HDD 13. The 2.5-inch HDD 13 has a capacity of 6 GB as described above which permits 10 titles of video game sandwich programs each having a capacity of 500 MB. The game machine body 16 includes a CPU 17 to which a RAM 20, a ROM 22, a graphic controller 23, a sound controller 24, an I/O controller 19 and an EIDE interface 21 are connected through an internal bus 18. The CPU 17 executes a game in accordance with a video game program read from the HDD 13. The RAM 20 is used when the CPU 17 executes the video game program. The ROM 22 has a basic program corresponding to an operation system (OS) stored therein. The graphic controller 23 produces a polygonal image or a 3D image in accordance with data supplied from the CPU 17 to output the image to the monitor 26. The sound controller 24 synthesizes sound effect in accordance with data supplied from the CPU 17 to output the sound effect to the speaker 27. As described above, the HDD 13 included in the game controller 10 is usually able to store 10 titles of video game programs. A program download system will schematically be described with reference to Figs. 4 and 5. Fig. 4 shows a download system in which a PC 35 is connected to the game controller 10 through the cables 15. Since the interface is similar to that for a usual PC, direct connection of the PC 35 as shown in the drawing enables a download system to be constituted. When a SCSI cable 36 is employed for the HDD interface as shown in Fig. 5, a plurality (three in the drawing) of game controllers 101, 102 and 103 can be connected to one PC 35 to permit simultaneous download. When the SCSI method is employed to establish the connection, connection of seven game controllers 10 is permitted. A method of downloading a game software program to the game controller will be described later. The procedure of the game controller 10 required to be performed from a moment at which a passenger lends the game controller 10 to which the game software program has been downloaded to a moment at which the game is started after the connector is connected to a connector 29 disposed at the side of the monitor 26, will now be described with reference to a flow chart shown in Fig. 6. Note that the description of the download to the description of the following flow chart is an embodiment of a method of executing a game according to the present invention. In step S1 the cursor of the game controller 10 is inserted into the connector 29 joined to the seat back 282. Then, the HDD 13 included in the game controller 10 is automatically turned on in step S2. In step S3 the index of, for example, five titles of video games recorded in the HDD 13 is automatically read in accordance with the basic program (the operating system) for the game machine body 16. As shown in Fig. 7 (A), a menu screen 37 is displayed on the monitor 26,. That is, the list of names of the games is displayed on the monitor 26. Note that the display of the list, which is performed by displaying names, may be performed by displaying icons. That is, an index which permits the identification of the games. In step S4 a cursor key of the game controller 10 vertically moves a cursor 38. When an enter key has been depressed at the title position of the video game required to be played, the selected game is started in step S5. In this description, "Crash Bandicoot" given #4 is started. When game is required to be completed, a game completion button in the switch 11 of the game controller 10 is depressed. Thus, the menu screen 37 is again displayed. In the foregoing state, the cables 15 of the game controller 10 can be removed from the connector 29. Whenever the game controller 10 is removed, the game machine body 16 resets all of the video games to start a standby mode. As described above, the video game system according to this embodiment has the structure that the game controller 10 has a plurality of game software programs stored therein. Therefore, the passenger is able to freely select a game. Since the games are stored in the game controller 10, any administration of the game software is not required in the airplane or the like. Since any marketed CD-ROM is not used, any burglar can be prevented. Another embodiment of the entertainment system incorporating the game controller according to the present invention will now be described. In this embodiment, also a video game system will now be described which is used in an airplane. As shown in Fig. 8, the video game system according to this embodiment is a system in which a plurality of game machine bodies 421, 422, 423, 424, 425, 426,...; to which a plurality of game controllers 411,412,413,414,415, 416,..., are connected are connected to one another through a network 43 and controlled by a system controller 44 through a network 43. The game controller 41 and the game machine body 42 have similar structures as the game controller 10 and the game machine body 16 shown in Fig. 1. Therefore, the description of the internal structures are omitted. The passengers play a game while looking monitors 451, 452, 453, 454, 455, 456,... The game machine body 42 joined in the lower portion of a side portion of each seat as shown in Fig. 2 is connected through a network 43, as shown in Fig. 8. Moreover, the game machine body 42 is connected to an upper system controller 44. Originally, the network 43 is used by the upper system controller 44 performs communication with the lower game machine body 42 to control the overall system. In this embodiment, when a plurality of passengers play a game, the network 43 is used to establish the communication between the game machine bodies 42 to play the game. The game machine body 42 structured similarly to the game machine body 16 shown in Fig. 1 is controlled by the system controller 43 to execute the following application program to start a competitive-type game. The procedure for staring the competitive-type game by using the application program will now be described with reference to Figs. 9 to 12. Although the procedure for playing the competitive-type game will now be described, the structure according to this embodiment may be applied to a case where, for example, a role-playing game is played in which a plurality of persons are able to take part. Fig. 9 is a flow chart showing the procedure of the application program. Figs. 10 to 12 show examples of display on the monitor when the foregoing application program is being performed. When the application program has been selected by an arbitrary passenger (hereinafter called a "request side" in accordance with the basic software program, the request side is caused to selected a competitive-type game in step SI 1 shown in Fig. 9. Specifically, "1. Japanese chess" and "2. mahjong" which are competitive-type games are displayed on the monitor 45 as a game menu, as shown in Fig. 10 (a). An assumption is made that "1. Japanese chess" has been selected. In step S12 a competitor is selected. As shown in Fig. 10 (b), a competition methods "1. computer", "2. specific person and "3. unspecific person" are displayed on the monitor 45. An assumption is made that "2. specific person" has been selected. In step S13 a determination is made that the selected competitor is "2. specific person" or "3. unspecific person". Since, for example, "2. specific person" is selected in step S12, display "please input seat number of the competitor" is displayed on the monitor as shown in Fig. 10 (c). Thus, the request side is caused to input the seat number. Then, the operation proceeds to step S20. The process in step S20 will be described later. When "3. unspecific person" has been selected as the competitor in step S12, the "unspecific person" is determined in step S13. Then, the operation is branched to step SI 4. In step S14 a competitor retrieval request command is sent to the system controller 44. Thus, "a competitor is being detected, please wait for a moment" is displayed on the monitor 45, as shown in Fig. 11 (d). When the system controller 44 has received the competitor retrieval request command in step S15, the system controller 44 sends a game competitor request command to all of the game machine bodies 42. Thus, the game machine bodies except for the game machine body which has sent the competitor retrieval request command receive the competitor request command from the system controller 44. A message for asking the game "ask for game xx from person at seat No. xx. Do you accept it ?" is displayed on the monitor 45 as shown in Fig. 11 (e). Thus, whether or not the passenger plays the game is selected by moving the cursor to either of "Yes" or "No" displayed on the monitor and by operating the enter key. The foregoing operations are used to determine whether or not the competitor has been detected in step S16. When a determination is made in step S17 that no input has been made for a predetermined time, a determination is made that the passenger does not want to play the game. Then, the operation proceeds to step S18 to send a message to the game machine body 42 of the request side which has required to play the competitive-type game, the message being a message having the content that "no competitor was found". When "Yes" has been selected on the monitor shown in Fig. 11 (e) by using the cursor or the like and a fact that a person who wants to play the game has been determined, the foregoing fact is sent to the system controller 44. The system controller 44 determines that the competitor has been found in accordance with the determination made in step S16. Then, the operation proceeds to step S19 so that a message having the content that the competitor has been detected is sent to the request side which has detected the competitor of the competitive-type game. Moreover, the seat number who has accepted the request is sent to the game machine body 42 of the request side. Thus, "competitor has been found" and "person at seat No. xx has accepted to play the game" are displayed on the monitor 45 of the request side, as shown in Fig. 11 (f). In step S20 the communication line between the game machine bodies 42 with which the game will be played is connected because the competitor has been determined. As shown in Fig. 12 (g), "Communication line is connected to game unit of seat No. xx. Please wait for a moment" is displayed on the monitor 45 of the request side. When the communication line has been connected in step S21, "Connection has been established with game unit of seat No. xx" is displayed on the monitor, as shown in Fig. 12 (h). Moreover, "You may input your nickname" is display to permit input of the nickname. While displaying a character string on the monitor, the cursor and the enter key are used to select characters to input the nickname. In step S21 the game software program of the competitor is turned on. When both of the game software programs have been turned on, "game will now be started. Please depress the start burton" is displayed on the monitor 45 as shown in Fig. 12 (i). Then, the game is played such that synchronization between the game machme bodies are established. As a matter of course, a fact that "You may input your niclcname" is displayed on the competitor side. Thus, the nickname is input by performing selection using the cursor key and the decision key. As shown in Fig. 13, the system controller 44 incorporates a CPU 50 to which a HDD 52, a ROM 53, a RAM 54 and a network I/F 55 are connected through an internal bus 5.1. The CPU 50 executes an operating system program read from the HDD 52 or the ROM 53. When an application program concerning the method of executing a game according to the present invention has been selected by the game machine body 42 of the request side owing to the process of the operating system program, the application program is fetched from the HDD 52 to the RAM 54 so as to be executed by the CPU 50. The application program causes the synchronization to be established between the game machine bodies 42. At this time, data conforming the protocol shown in Fig. 14 is communicated through the network 43 among the system controller 44 and the game machine bodies 42. In Fig. 14, the address (To address) of the transmission side and the address (From address) of the receiver side is expressed by Axx, where A indicates the seat row which is expressed by A-K. When the seat row A is Z, the address of the system controller 44 is indicated. The residual portion xx indicates the residual seat rows which are expressed by 1-99. When the seat row xx is 00, a broadcast is indicated with which data is commonly sent to all of the seats. Byte count follows the address (From address) of the transmission side to indicate the number of bytes of data following a command code following the byte count. The command code is required to establish the synchronization so as to play the competitive-type game. Coimnand codes 01 h to 04h are used to detect the competitor. Specifically, 01 h serves as a game competitor retrieval request coimnand code, 02h serves as a game competitor request coimnand code, 03h serves as a game competitor request status; Yes command code and 04h serves a game competitor request status; No coimnand code. Command codes 10h to 14h are used to rum a game of the game machine body on after the competitor has been decided. Specifically, 1 Oh serves as a game select coimnand code, llh serves as a game start command code, 12h is a game stop command code, 13h is a send message command code for sending a message, such as "Competitor has been decided" and 14h serves as a send nickname coimnand code for sending nickname. Moreover, 20h serves as a contact communication line command code for connecting the communication line. Coimnand 30h game machine body is a capsule coimnand to directly send data following the coimnand to the game software. Usually, the capsule command s used to communicate commands for use in the game. The foregoing coimnand eliminates a necessity for producing a protocol for each game in a case where a plurality of games are installed. Referring to a flow chart shown in Fig. 9, the process which is performed in step S14 to send a competitor retrieval request coimnand to the system controller 44 is performed such that the command code of the foregoing protocol is Command 01b. In a process (the system controller sends the game competitor request to all of the game machine bodies) which is performed in step S15, the command is Command 02h. When "Yes" or "No" has been selected by using the cursor and the enter key with the display (ask to play the game) on the monitor shown in Fig. 11 (e), the command code of the foregoing protocol is Command 03h or 04h. The message indicating a fact that a competitor has been detected is sent by Command 13h. The content of the message is described in a Date region. To connect the communication line between the game machine bodies in step S20, the communication line is connected by using Command 20h. Command 14h is used to send nickname, and command l0h is used to select a game. When the game is started in step S21, Command 1 1h is used. An example of communication will now be described with reference to Fig. 15, which is established when a competitive-type game (for example, Japanese chess) is played between the request side (the master) and the competitor (the slave) after the process which is required before the competitive-type game is started in accordance with the application program included in the flow chart shown in Fig. 9. An initial screen instruction is issued from the master in accordance with the capsule Command 30h. Then, setting the slave to be the forestalled side is performed by the master by using the capsule Command 30h. In the following processes, the capsule Command 30h is used. Then, the master issues a game start instruction. Simultaneously, time count on the master side is started. As a matter of course, the foregoing time count is displayed on the monitor of the slave as well as that of the master., When the master performs a first move as the inferior side during the foregoing time count, time counting is interrupted. The set data of the first move of the inferior side is sent by using the capsule Command 30h. Then, the slave displays the first move as the inferior side on the monitor. At this time, the right of attack is shifted from the master to the slave by using the capsule Command 30h. Thus, time count on the slave side is started. When a first move of the forestalled side is performed by the slave during the foregoing time count, time counting is interrupted. Then, set data of the first move of the forestalled side is sent to the master by using the capsule Command 30h. Thus, the first move of the forestalled side is displayed on the monitor of the master. At this time, the right of attack is shifted from the slave to the master. Then, time counting on the master side is started. Then, checkmate is decided, the foregoing sequential process is repeated. When the checkmate has been decided, the game is completed. As described above, the entertainment system shown in Fig. 8 enables passengers at the distant seats to play the competitive-type game, such as Japanese chess or a chess. In the foregoing case, the game software programs have been stored in the game controller which is connected to the game machine body. The system controller performs control to cause the game to be played such that the synchronization is established by using protocol data, as shown in Fig. 14. Therefore, any costly network having a large transmission capacity is not required. A method of downloading the game software program to the game controller which has schematically described with reference to Figs. 4 and 5 will now be described with reference to Figs. 16 to 20. The game controller having a small size (2.5') as described above includes the HDD having a storage capacity of, for example, 6 GB. Therefore, 10 titles of game software programs each having a capacity of 500 MB can be stored. A specific method of downloading the game software program to the game controller is shown in Fig. 16. This example is arranged to perform the download by using a download application program. A marketed personal computer (PC) 61 is employed as a server for the game software program. A SCSI interface 69j is employed as the interface with the game controllers 411, 412,..., 417. The PC 61 incorporates a CPU 62 to which a HDD 64, a network I/F 65, a CD-ROM player 66, a DVD-ROM player 67, a memory 68, such as a RAM, and SCSI I/F (#1) 69,,..., SCSI I/F (#n) 69n are connected through an internal bus 63. The CPU 62 executes an operating system program read from the HDD 64, the CD-ROM player 66 or the DVD-ROM player 67. When execution of the downloaded application program has been selected owing to the process performance in accordance with the operating system program, the program is read from the HDD 64, the CD-ROM player 66 or the DVD-ROM player 67 so as to install the program on the memory 68 so as to be executed by the CPU 62. The foregoing downloaded application program will be described later. Not larger than 7 game controllers 41 1 412,..., 417 can be connected to the SCSI I/F 69 of the PC 61. Therefore, when n SCSI I/F are prepared, n X 7 game controllers 2-1- can be connected. Thus, the game software program can be downloaded to n X 7 game controllers. Setting of the ID to the n SCSI I/F is, as shown in Fig. 17, performed by simply depressing the connection connector to set the ID assigned to the connection connector. A process for executing the downloaded application program is performed by the download system shown in Fig. 16 will now be described with reference to Fig. 18. As shown in Fig. 16, the PC and n X 7 game controllers, and then the power source of the PC is turned on. Thus, the downloaded application program is started on the PC.

As shown in Fig. 1, a video game system 1 for use an airplane incorporates a
game controller 10; and a game machine body 16 to which the game controller 10 is connected through cables 15. Also a monitor 26 and a speaker 27 are connected to the game machine body 16. The game controller 10 includes a small-size HDD 13 (2.5'). The HDD 13 drives a HD having a storage capacity of 6 GB. Since a usual game title has a capacity of 500 MB, the HD of the HDD 13 is able to store 10 titles. The recording medium is limited according to the size of the program to be recorded. The recording medium may be another medium, such as a flush disc or a semiconductor recording medium. The foregoing recording medium may be a removable medium. As shown in Fig. 2, the game controller 10, the game machine body 16 and the

monitor 26 of the video game system may be disposed in the periphery of a seat 2 in an airplane. For example, a passenger at a seat 21 executes a video game while viewing a monitor 261 such that a game controller 101 is joined to a connector 291 provided for a seat back 282 of the forward seat 22 through the cables 15. The game machine body 16, is joined to a lower portion 30, of the seat 2,. The cable is connected to the connector 29, of the seat back 282 of the forward seat 22 through the seat and the floor. A video output from the game machine body 161 and an input to the game controller 10, are supplied to the monitor 261 of the front seat 22 and the connector 291 disposed at the side of the monitor 26,. Note that the seat back 281 of the seat 21 is provided with a monitor 260 for a passenger in the rearward seat (not shown). A game controller 100 is joined to the connector 290. A game machine body 162 for a passenger who takes the seat 22 is joined to the lower portion of the seat 22

The I/O controller 12 is joined to the operation surface 31 of the game controller 10. Information items of the switch 11 and so forth are collectively interfaced with the game machine body 16. The EIDE interface 14 serves as an interface with the 2.5-inch HDD 13. The 2.5-inch HDD 13 has a capacity of 6 GB as described above which permits 10 titles of video game sandwich programs each having a capacity of 500 MB.

The game machine body 16 includes a CPU 17 to which a RAM 20, a ROM 22, a graphic controller 23, a sound controller 24, an I/O controller 19 and an EIDE interface 21 are connected through an internal bus 18.
The CPU 17 executes a game in accordance with a video game program read from the HDD 13. The RAM 20 is used when the CPU 17 executes the video game program. The ROM 22 has a basic program corresponding to an operation system (OS) stored therein.
The graphic controller 23 produces a polygonal image or a 3D image in accordance with data supplied from the CPU 17 to output the image to the monitor 26. The sound controller 24 synthesizes sound effect in accordance with data supplied from the CPU 17 to output the sound effect to the speaker 27.
As described above, the HDD 13 included in the game controller 10 is usually able to store 10 titles of video game programs. A program download system will schematically be described with reference to Figs. 4 and 5.
Fig. 4 shows a download system in which a PC 35 is connected to the game controller 10 through the cables 15. Since the interface is similar to that for a usual PC, direct connection of the PC 35 as shown in the drawing enables a download system to be constituted.
When a SCSI cable 36 is employed for the HDD interface as shown in Fig. 5, a plurality (three in the drawing) of game controllers 101, 102 and 103 can be connected to one PC 35 to permit simultaneous download. When the SCSI method is employed

to establish the connection, connection of seven game controllers 10 is permitted. A method of downloading a game software program to the game controller will be described later.
The procedure of the game controller 10 required to be performed from a moment at which a passenger lends the game controller 10 to which the game software program has been downloaded to a moment at which the game is started after the connector is connected to a connector 29 disposed at the side of the monitor 26, will now be described with reference to a flow chart shown in Fig. 6. Note that the description of the download to the description of the following flow chart is an embodiment of a method of executing a game according to the present invention.
In step S1 the cursor of the game controller 10 is inserted into the connector 29 joined to the seat back 282. Then, the HDD 13 included in the game controller 10 is automatically turned on in step S2.
In step S3 the index of, for example, five titles of video games recorded in the HDD 13 is automatically read in accordance with the basic program (the operating system) for the game machine body 16. As shown in Fig. 7 (A), a menu screen 37 is displayed on the monitor 26,. That is, the list of names of the games is displayed on the monitor 26. Note that the display of the list, which is performed by displaying names, may be performed by displaying icons. That is, an index which permits the identification of the games.
In step S4 a cursor key of the game controller 10 vertically moves a cursor 38.

When an enter key has been depressed at the title position of the video game required to be played, the selected game is started in step S5. In this description, "Crash Bandicoot" given #4 is started.
When game is required to be completed, a game completion button in the switch 11 of the game controller 10 is depressed. Thus, the menu screen 37 is again displayed. In the foregoing state, the cables 15 of the game controller 10 can be removed from the connector 29.
Whenever the game controller 10 is removed, the game machine body 16 resets all of the video games to start a standby mode.
As described above, the video game system according to this embodiment has the structure that the game controller 10 has a plurality of game software programs stored therein. Therefore, the passenger is able to freely select a game. Since the games are stored in the game controller 10, any administration of the game software is not required in the airplane or the like. Since any marketed CD-ROM is not used, any burglar can be prevented.
Another embodiment of the entertainment system incorporating the game controller according to the present invention will now be described. In this embodiment, also a video game system will now be described which is used in an airplane.
As shown in Fig. 8, the video game system according to this embodiment is a system in which a plurality of game machine bodies 421, 422, 423, 424, 425, 426,...; to

which a plurality of game controllers 411,412,413,414,415, 416,..., are connected are connected to one another through a network 43 and controlled by a system controller 44 through a network 43. The game controller 41 and the game machine body 42 have similar structures as the game controller 10 and the game machine body 16 shown in Fig. 1. Therefore, the description of the internal structures are omitted. The passengers play a game while looking monitors 451, 452, 453, 454, 455, 456,...
The game machine body 42 joined in the lower portion of a side portion of each seat as shown in Fig. 2 is connected through a network 43, as shown in Fig. 8. Moreover, the game machine body 42 is connected to an upper system controller 44. Originally, the network 43 is used by the upper system controller 44 performs communication with the lower game machine body 42 to control the overall system. In this embodiment, when a plurality of passengers play a game, the network 43 is used to establish the communication between the game machine bodies 42 to play the game.
The game machine body 42 structured similarly to the game machine body 16 shown in Fig. 1 is controlled by the system controller 43 to execute the following application program to start a competitive-type game. The procedure for staring the competitive-type game by using the application program will now be described with reference to Figs. 9 to 12. Although the procedure for playing the competitive-type game will now be described, the structure according to this embodiment may be applied to a case where, for example, a role-playing game is played in which a plurality

of persons are able to take part.
Fig. 9 is a flow chart showing the procedure of the application program. Figs. 10 to 12 show examples of display on the monitor when the foregoing application program is being performed.
When the application program has been selected by an arbitrary passenger (hereinafter called a "request side" in accordance with the basic software program, the request side is caused to selected a competitive-type game in step SI 1 shown in Fig. 9. Specifically, "1. Japanese chess" and "2. mahjong" which are competitive-type games are displayed on the monitor 45 as a game menu, as shown in Fig. 10 (a). An assumption is made that "1. Japanese chess" has been selected. In step S12 a competitor is selected. As shown in Fig. 10 (b), a competition methods "1. computer", "2. specific person and "3. unspecific person" are displayed on the monitor 45. An assumption is made that "2. specific person" has been selected.
In step S13 a determination is made that the selected competitor is "2. specific person" or "3. unspecific person". Since, for example, "2. specific person" is selected in step S12, display "please input seat number of the competitor" is displayed on the monitor as shown in Fig. 10 (c). Thus, the request side is caused to input the seat number. Then, the operation proceeds to step S20. The process in step S20 will be described later.
When "3. unspecific person" has been selected as the competitor in step S12, the "unspecific person" is determined in step S13. Then, the operation is branched to

step SI 4. In step S14 a competitor retrieval request command is sent to the system controller 44. Thus, "a competitor is being detected, please wait for a moment" is displayed on the monitor 45, as shown in Fig. 11 (d). When the system controller 44 has received the competitor retrieval request command in step S15, the system controller 44 sends a game competitor request command to all of the game machine bodies 42. Thus, the game machine bodies except for the game machine body which has sent the competitor retrieval request command receive the competitor request command from the system controller 44. A message for asking the game "ask for game xx from person at seat No. xx. Do you accept it ?" is displayed on the monitor 45 as shown in Fig. 11 (e). Thus, whether or not the passenger plays the game is selected by moving the cursor to either of "Yes" or "No" displayed on the monitor and by operating the enter key. The foregoing operations are used to determine whether or not the competitor has been detected in step S16. When a determination is made in step S17 that no input has been made for a predetermined time, a determination is made that the passenger does not want to play the game. Then, the operation proceeds to step S18 to send a message to the game machine body 42 of the request side which has required to play the competitive-type game, the message being a message having the content that "no competitor was found".
When "Yes" has been selected on the monitor shown in Fig. 11 (e) by using the cursor or the like and a fact that a person who wants to play the game has been determined, the foregoing fact is sent to the system controller 44. The system

controller 44 determines that the competitor has been found in accordance with the determination made in step S16. Then, the operation proceeds to step S19 so that a message having the content that the competitor has been detected is sent to the request side which has detected the competitor of the competitive-type game. Moreover, the seat number who has accepted the request is sent to the game machine body 42 of the request side. Thus, "competitor has been found" and "person at seat No. xx has accepted to play the game" are displayed on the monitor 45 of the request side, as shown in Fig. 11 (f).
In step S20 the communication line between the game machine bodies 42 with which the game will be played is connected because the competitor has been determined. As shown in Fig. 12 (g), "Communication line is connected to game unit of seat No. xx. Please wait for a moment" is displayed on the monitor 45 of the request side. When the communication line has been connected in step S21, "Connection has been established with game unit of seat No. xx" is displayed on the monitor, as shown in Fig. 12 (h). Moreover, "You may input your nickname" is display to permit input of the nickname. While displaying a character string on the monitor, the cursor and the enter key are used to select characters to input the nickname. In step S21 the game software program of the competitor is turned on. When both of the game software programs have been turned on, "game will now be started. Please depress the start burton" is displayed on the monitor 45 as shown in Fig. 12 (i). Then, the game is played such that synchronization between the game

machme bodies are established. As a matter of course, a fact that "You may input your niclcname" is displayed on the competitor side. Thus, the nickname is input by performing selection using the cursor key and the decision key.
As shown in Fig. 13, the system controller 44 incorporates a CPU 50 to which a HDD 52, a ROM 53, a RAM 54 and a network I/F 55 are connected through an internal bus 5.1. The CPU 50 executes an operating system program read from the HDD 52 or the ROM 53. When an application program concerning the method of executing a game according to the present invention has been selected by the game machine body 42 of the request side owing to the process of the operating system program, the application program is fetched from the HDD 52 to the RAM 54 so as to be executed by the CPU 50.
The application program causes the synchronization to be established between the game machine bodies 42. At this time, data conforming the protocol shown in Fig. 14 is communicated through the network 43 among the system controller 44 and the game machine bodies 42. In Fig. 14, the address (To address) of the transmission side and the address (From address) of the receiver side is expressed by Axx, where A indicates the seat row which is expressed by A-K. When the seat row A is Z, the address of the system controller 44 is indicated. The residual portion xx indicates the residual seat rows which are expressed by 1-99. When the seat row xx is 00, a broadcast is indicated with which data is commonly sent to all of the seats. Byte count follows the address (From address) of the transmission side to indicate the number of

bytes of data following a command code following the byte count. The command code is required to establish the synchronization so as to play the competitive-type game. Coimnand codes 01 h to 04h are used to detect the competitor. Specifically, 01 h serves as a game competitor retrieval request coimnand code, 02h serves as a game competitor request coimnand code, 03h serves as a game competitor request status; Yes command code and 04h serves a game competitor request status; No coimnand code. Command codes 10h to 14h are used to rum a game of the game machine body on after the competitor has been decided. Specifically, 1 Oh serves as a game select coimnand code, llh serves as a game start command code, 12h is a game stop command code, 13h is a send message command code for sending a message, such as "Competitor has been decided" and 14h serves as a send nickname coimnand code for sending nickname. Moreover, 20h serves as a contact communication line command code for connecting the communication line. Coimnand 30h game machine body is a capsule coimnand to directly send data following the coimnand to the game software. Usually, the capsule command s used to communicate commands for use in the game. The foregoing coimnand eliminates a necessity for producing a protocol for each game in a case where a plurality of games are installed.
Referring to a flow chart shown in Fig. 9, the process which is performed in step S14 to send a competitor retrieval request coimnand to the system controller 44 is performed such that the command code of the foregoing protocol is Command 01b. In a process (the system controller sends the game competitor request to all of the

game machine bodies) which is performed in step S15, the command is Command 02h. When "Yes" or "No" has been selected by using the cursor and the enter key with the display (ask to play the game) on the monitor shown in Fig. 11 (e), the command code of the foregoing protocol is Command 03h or 04h. The message indicating a fact that a competitor has been detected is sent by Command 13h. The content of the message is described in a Date region. To connect the communication line between the game machine bodies in step S20, the communication line is connected by using Command 20h. Command 14h is used to send nickname, and command l0h is used to select a game. When the game is started in step S21, Command 1 1h is used.
An example of communication will now be described with reference to Fig. 15, which is established when a competitive-type game (for example, Japanese chess) is played between the request side (the master) and the competitor (the slave) after the process which is required before the competitive-type game is started in accordance with the application program included in the flow chart shown in Fig. 9.
An initial screen instruction is issued from the master in accordance with the capsule Command 30h. Then, setting the slave to be the forestalled side is performed by the master by using the capsule Command 30h. In the following processes, the capsule Command 30h is used. Then, the master issues a game start instruction. Simultaneously, time count on the master side is started. As a matter of course, the foregoing time count is displayed on the monitor of the slave as well as that of the master., When the master performs a first move as the inferior side during the

foregoing time count, time counting is interrupted. The set data of the first move of the inferior side is sent by using the capsule Command 30h. Then, the slave displays the first move as the inferior side on the monitor. At this time, the right of attack is shifted from the master to the slave by using the capsule Command 30h. Thus, time count on the slave side is started. When a first move of the forestalled side is performed by the slave during the foregoing time count, time counting is interrupted. Then, set data of the first move of the forestalled side is sent to the master by using the capsule Command 30h. Thus, the first move of the forestalled side is displayed on the monitor of the master. At this time, the right of attack is shifted from the slave to the master. Then, time counting on the master side is started. Then, checkmate is decided, the foregoing sequential process is repeated. When the checkmate has been decided, the game is completed.
As described above, the entertainment system shown in Fig. 8 enables passengers at the distant seats to play the competitive-type game, such as Japanese chess or a chess. In the foregoing case, the game software programs have been stored in the game controller which is connected to the game machine body. The system controller performs control to cause the game to be played such that the synchronization is established by using protocol data, as shown in Fig. 14. Therefore, any costly network having a large transmission capacity is not required.
A method of downloading the game software program to the game controller which has schematically described with reference to Figs. 4 and 5 will now be

described with reference to Figs. 16 to 20.
The game controller having a small size (2.5') as described above includes the HDD having a storage capacity of, for example, 6 GB. Therefore, 10 titles of game software programs each having a capacity of 500 MB can be stored.
A specific method of downloading the game software program to the game controller is shown in Fig. 16. This example is arranged to perform the download by using a download application program. A marketed personal computer (PC) 61 is employed as a server for the game software program. A SCSI interface 69j is employed as the interface with the game controllers 411, 412,..., 417.
The PC 61 incorporates a CPU 62 to which a HDD 64, a network I/F 65, a CD-ROM player 66, a DVD-ROM player 67, a memory 68, such as a RAM, and SCSI I/F (#1) 69,,..., SCSI I/F (#n) 69n are connected through an internal bus 63.
The CPU 62 executes an operating system program read from the HDD 64, the CD-ROM player 66 or the DVD-ROM player 67. When execution of the downloaded application program has been selected owing to the process performance in accordance with the operating system program, the program is read from the HDD 64, the CD-ROM player 66 or the DVD-ROM player 67 so as to install the program on the memory 68 so as to be executed by the CPU 62. The foregoing downloaded application program will be described later.
Not larger than 7 game controllers 41 1 412,..., 417 can be connected to the SCSI I/F 69 of the PC 61. Therefore, when n SCSI I/F are prepared, n X 7 game controllers
2-1-

can be connected. Thus, the game software program can be downloaded to n X 7 game controllers. Setting of the ID to the n SCSI I/F is, as shown in Fig. 17, performed by simply depressing the connection connector to set the ID assigned to the connection connector.
A process for executing the downloaded application program is performed by the download system shown in Fig. 16 will now be described with reference to Fig. 18. As shown in Fig. 16, the PC and n X 7 game controllers, and then the power source of the PC is turned on. Thus, the downloaded application program is started on the PC. After the downloaded application program has been started, game software programs downloaded to the connected game controller are retrieved.
After the retrieval has been completed, download of the game software is performed or erase of the game software recorded on the controller is performed is selected by performing display on the monitor of the PC to select "1. download" or "2. erase" as the "game controller maintenance", as shown in Fig. 18 (a). When "I. download" has been selected, a list of the game software programs recorded on in the PC is displayed as shown in Fig. 18 (b). Thus, the game software required to be downloaded is selected. In this case, for example, "3. Japanese chess" and "6. base ball" are selected. After the selection has been performed, the decision button is depressed. When the decision button has been depressed, download is started. During the download, a fact that the download is being performed and a degree of completion of the download are indicated with "%" as shown in Fig. 18 (c). After the download

has been completed, the first screen shown in Fig. 18 (a) is automatically displayed.
When "2. erase" is selected on the first screen shown in Fig. 18 (a), a mode for erasing the game software is started. The foregoing mode is employed when new game software cannot be downloaded because the capacity of the recording medium included in the game controller, which is HDD in this embodiment, is filled with data or when the game controller is abolished.
When the erase is selected on the first screen, the list of the game software programs in the connected game controller is displayed on the monitor of the PC as shown in Fig. 19 (d). Thus, a game erase screen with which the name of the game required to be erased is input is displayed on the monitor, as shown in Fig. 19 (e). An assumption is made that erase of "chess" is selected. Thus, the color of the background for the selected game name "chess" is changed, as shown in Fig. 19 (f). Then, a confirmation dialogue is displayed, as shown in Fig. 19 (g). Also display "erase of selected game permitted ?" is performed. The confirmation button and the cancel button are operated to perform the confirmation. When the confirmation button has been depressed, the erase is performed. After erase has been completed, the display of the list is restored. When the completion button has been depressed on the list display screen, the menu screen shown in Fig. 18 (a) is again displayed.
Therefore, the download system 60 according to this embodiment enables game software to be downloaded to a multiplicity of (n X 7) game controllers by using the SCSI I/F of the PC. That is, the foregoing video game system is arranged to download

the game software program on the off-line. Therefore, change can quickly be performed.
Fig. 20 shows another embodiment for downloading the game software program to the game controller. Also this embodiment is arranged to perform the download by executing a download application program. The interface between the game controller and the PC is established by IEEE 1394 interface.
In the download system 70. a PC 71 incorporates a CPU 72 to which a HDD 74, a network I/F 75, a CD-ROM player 76, a DVD-ROM player 77, a memory 78, such as a RAM and IEEE 1394 I/F (#1) 791, ..., IEEE 1394 I/F (#n) 79n are connected through an internal bus 73. The structures and operations of the CPU 72, the HDD 74, the network I/F 75, the CD-ROM player 76, the DVD-ROM player 77 and the memory 78 of the PC 71 are similar to those in the PC 61 shown in Fig. 16.
A 16 or smaller number of 411, 412, ...,4119 can be connected to the IEEE 1394 I/F per bus. Therefore, when n IEEE 1394 I/F are prepared, n X 16 game controllers can be connected. Thus, the game software program can simultaneously be downloaded to n X 16 game controllers.
The process for executing the foregoing downloaded application program by the download system shown in Fig. 20 is similar to that described with reference to Figs. 18 and 19.
Therefore, the download system 70 according to this embodiment enables the game software to be downloaded to a multiplicity of (n X 16) game controllers by

using the IEEE 1394 I/F. That is, the game software program is downloaded with respect to the video game video game system by the off-line method. Therefore, quick change is permitted.
