  FIG. 5 three-dimensionally represents a virtual space in a game executed in the game system. As shown in FIG. 5, this virtual space is roughly divided into two worlds. The first world is the upper world where the height Y is around zero or more, and the second world is the lower world where Y is around -10. In the example of FIG. 5, there are ladders floating in the air, characters, clouds, and birds operated by the player in the upper world, and monsters, houses, castles, and the ground exist in the lower world. In the game system, the stationary game machine 20 is in charge of the upper world, and the portable game machine 50 is in charge of the lower world. Here, the stationary game machine 20 handles a three-dimensional game space and displays a three-dimensional game image on a TV monitor, and the portable game machine 50 handles a two-dimensional game space and displays an LCD 502. It is assumed that a two-dimensional game space is displayed.

  FIG. 6 schematically shows the game spaces handled by the stationary game machine (GC) 20 and the portable game machine (GBA) 50. In the three-dimensional game space (hereinafter referred to as the GC world) that the stationary game machine 20 is in charge of, the coordinates of each object are represented by (X, Y, Z). On the other hand, since the concept of height does not exist in the two-dimensional game space (hereinafter referred to as the AGB world) handled by the portable game machine 50, the coordinates of each object are represented by (X, Z). However, although there is no concept of height in the AGB world, when it is necessary to perform processing according to a virtual positional relationship with the GC world, the height at which the object in the AGB world is located is Y = Considered -10. In FIG. 6, the player object exists in the GC world, but if a ladder floating in the air is stepped off, the player object falls into the AGB world.

  7A and 7B show a game image generated by the stationary game machine 20 and displayed on the TV monitor 10 when the player object exists in the GC world, and generated by the portable game machine 50. FIG. Each example of the game image displayed on the LCD 502 is shown. As shown in FIG. 7A, the TV monitor 10 displays a three-dimensional GC world, and further displays a shadow that an object in the GC world drops on other objects in the GC world. On the other hand, as shown in FIG. 7B, the LCD 502 displays a two-dimensional GBA world together with shadows of objects in the GC world (player characters, ladders, clouds and birds floating in the air). Thereby, compared with the case where a shadow is not displayed, the player can grasp | ascertain easily the positional relationship of the monster which exists in the GBA world, and the player character which exists in the GC world, for example. Further, as shown in FIG. 7B, the game screen displayed on the LCD 502 is displayed darker than usual as a whole. Thereby, it is possible to make the player effectively recognize that the player character exists in the GC world instead of the GBA world.

  FIG. 8 shows the positions of cameras and lights arranged in the GC world when the player object exists in the GC world. Thus, when the player object exists in the GC world, the camera is installed obliquely above and behind the player object, and the light is installed at a position slightly deviated from the camera. The stationary game machine 20 displays a scene when the player character is viewed from the camera on the TV monitor 10 together with a shadow generated according to the position of the light. As a method for displaying a shadow, any known technique such as a shadow map or a shadow volume can be used.

  On the other hand, the shadow shown in FIG. 7B is displayed by a method different from the GC world. Hereinafter, a method for displaying the shadow of an object in the GC world in the GBA world will be described with reference to FIG. The portable game machine 50 does not generate shadow images one by one based on the shape of the objects in the GC world, but displays shadows in the GBA world using shadow images created in advance for each object in the GC world. More specifically, as shown in FIG. 9, from the coordinates (z0, y0, z0) of the lights arranged in the GC world and the reference coordinates (z1, y1, z1) of the objects in the GC world, the GBA world (Y = -10 plane) The shadow image placement coordinates (x2, z2) are calculated, and the shadow image is placed so that the placement coordinates coincide with the shadow image reference coordinates. At this time, when the light is a point light source, the size of the shadow image is enlarged or reduced according to the height y1 of the object in the GC world. That is, when y1 is large, the shadow image is enlarged, and when y1 is small, the shadow image is reduced. Thereby, a more realistic shadow is displayed. In the example shown in FIG. 9, the arrangement coordinates of the shadow image are obtained based on both the coordinates of the light and the coordinates of the objects in the GC world. For example, when the light from the light is approximated as parallel light, If the coordinates of the objects in the GC world are known, the arrangement coordinates of the shadow image can be calculated.

  Next, a case where the player object falls (that is, moves) from the GC world to the AGB world will be described. FIG. 10 schematically shows the game spaces handled by the stationary game machine (GC) 20 and the portable game machine (GBA) 50 when the player object exists in the GBA world. In FIG. 10, the player object exists in the GBA world. For example, in the GBA world, if the player object overlaps with a ladder object for going up to the GC world, the player object can return to the GC world.

  11A and 11B show a game image generated by the stationary game machine 20 and displayed on the TV monitor 10 when the player object exists in the GBA world, and generated by the portable game machine 50. FIG. Each example of the game image displayed on the LCD 502 is shown. As shown in FIG. 11A, the TV monitor 10 displays a three-dimensional GC world together with shadows of objects (monsters, castles, and player characters) in the GBA world. Thereby, compared with the case where no shadow is displayed, for example, the player can easily grasp the positional relationship between the player character existing in the GBA world and the ladder floating in the air existing in the GC world. As shown in FIG. 11A, the game screen displayed on the TV monitor 10 shows a state when the GC world is looked up from below. Thereby, when the player operating the player character displayed on the LCD 502 of the portable game machine 50 moves his / her line of sight from the portable game machine 50 at hand to the TV monitor 10 to check the state of the GC world, Since the TV monitor 10 displays a scene that can be seen when the player character looks up, it is possible to naturally check the state of the GC world as if the player himself was a character in the game. it can. Needless to say, this effect is enhanced by placing the camera in the vicinity of the player character. Further, such a display allows the user to instantly recognize that the player character does not exist in the GC world. Further, as shown in FIG. 11A, the game screen displayed on the TV monitor 10 is displayed darker than usual. Thereby, it is possible to make the player effectively recognize that the player character exists in the GBA world instead of the GC world. Further, even when the player character unexpectedly falls from the GC world to the GBA world, the screen becomes dark, so that the player can instantly recognize that the player character has fallen into the GBA world. On the other hand, as shown in FIG. 11B, the LCD 502 displays a two-dimensional GBA world including the player character. At this time, unlike the case shown in FIG. 7B, the game screen displayed on the LCD 502 is displayed with normal brightness.

  FIG. 12 shows the positions of cameras and lights arranged in the GC world when the player object exists in the GBA world. As described above, when the player object exists in the GBA world, the camera is installed obliquely below and behind the player, and the light is installed at a position slightly deviated from the camera.

  Hereinafter, a method for displaying the shadow shown in FIG. The shadow shown in FIG. 11A is based on the shape of the 3D object and the position of the light after the GBA world object is virtually arranged in the GC world as a 3D object as shown in FIG. Thus, it can be displayed in the GC world by performing a known process such as a shadow map or a shadow volume. However, in that case, a three-dimensional object corresponding to an object in the GBA world is prepared in advance on the stationary game machine 20 side, and a shadow volume or the like is generated based on the three-dimensional object to draw a shadow. It is necessary to perform processing. Therefore, in this embodiment, in order to further reduce the processing load, as shown in FIG. 14, a shadow volume is generated for each object in the GBA world and the data is prepared in advance on the stationary game machine 20 side. The shadow is displayed using this shadow volume. More specifically, when the reference coordinates of an object in the GBA world are (x3, z3), the coordinates are notified from the portable game machine 50 to the stationary game machine 20. In the stationary game machine 20, the shadow volume is arranged so that the reference coordinates of the shadow volume corresponding to the object coincide with the coordinates (x3, -10, y3) of the GC world, and based on the arranged shadow volume. The shadow of the object in the GBA world is displayed on the GC world. As a result, it is not necessary to generate shadow volumes one by one, and the processing load for displaying shadows is reduced. When displaying a shadow using a shadow volume, a stencil buffer not shown in FIG. 3 is used as appropriate. A shadow map may be used instead of the shadow drawing method using the shadow volume shown in FIG. In this case, for an object located at (x3, -10, z3) in the GBA world, a shadow map process is performed after a polygon having a shape corresponding to the outline of the object is placed at (x3, -1, z3), for example. Can be done.

Next, a memory map of each storage device used in this game system will be described.
FIG. 15 shows a memory map of the DVD 30. The DVD 30 stores various moving programs, various drawing programs, and other game processing programs as program data. The movement program is a program for moving an object, and the drawing program is a program for drawing an object. As the moving program, a moving program for a player object, a moving program for a simple moving object in the GC world, a moving program for a complex moving object in the GC world, and a moving program for a simple moving object in the GBA world are stored. The simple moving object is an object that simply moves in the game space based on a predetermined movement pattern (for example, a cloud that flows in a certain direction as shown in FIG. 6). Since the movement pattern changes depending on the situation, it is an object (for example, a bird shown in FIG. 6) whose destination is difficult to predict. In the movement program for the simple moving object in the GC world and the moving program for the simple moving object in the GBA world, as shown in FIG. 16, the definition data of the movement pattern is defined for each simple moving object. The drawing program includes a player object drawing program, a GC world simple moving object drawing program, a GC world complex moving object drawing program, a GC world fixed object drawing program, a GC world topographic object drawing program, a GC A shadow drawing program for world objects, a shadow drawing program for simple moving objects in the GBA world, a shadow drawing program for complex moving objects in the GBA world, and a shadow drawing program for fixed objects in the GBA world are stored. Note that the fixed object is an object that always exists at a fixed position in the game space (for example, a ladder that floats in the air shown in FIG. 6).

  Further, the arrangement data (coordinate data) of the GC world terrain object data is stored in the DVD 30 (however, in the example shown in FIG. 6, there is no GC world terrain object).

  Further, the DVD 30 stores coordinate data of each fixed object in the GC world and coordinate data of each fixed object in the GBA world as fixed object arrangement data.

  The DVD 30 also includes, as polygon / texture data, polygon / texture data for player objects, polygon / texture data for simple moving objects in the GC world, polygon / texture data for complex moving objects in the GC world, Polygon / texture data for fixed objects and polygon / texture data for terrain objects in the GC world are stored.

  Also, on the DVD 30, shadow volume data for displaying the shadow of the player object, shadow volume data for displaying the shadow of the simple moving object in the GBA world, and the shadow of the complex moving object in the GBA world are used as shadow volume data. Stored are shadow volume data for displaying and shadow volume data for displaying shadows of fixed objects in the GBA world.

  The DVD 30 also stores data other than the above, such as sound data.

  There is no GBA world object in the GC world displayed on the TV monitor 10, and only its shadow is displayed. Therefore, the polygon 30 texture data corresponding to each object in the GBA world is not stored in the DVD 30. Instead, shadow volume data corresponding to each object in the GBA world is stored.

  FIG. 17 shows a memory map of the main memory 207 of the stationary game machine 20. In the main memory 207, an area for storing a synchronization counter for synchronizing processing with the portable game machine 50, and a player object indicating whether the player object exists in the GC world or the GBA world The area for storing the flag, or whether the light exists in the GC world (that is, the GC world is illuminated from above the GC world) or exists in the GBA world (that is, the GC world is illuminated from below the GC world) An area for storing a light flag indicating whether or not, an area for storing light color data for changing the brightness of the light, an area for storing the coordinates of the player object, and each simple in the GC world An area for storing the coordinates of moving objects and an area for storing the coordinates of each complex moving object in the GC world An area for storing the coordinates of each simple moving object in the GBA world predicted based on the movement pattern, and an area for storing the coordinates of each complex moving object in the GBA world received from the portable game machine 50. As appropriate.

  Further, the main memory 207 appropriately has an area for storing light coordinates, an area for storing camera coordinates, and an area for storing operation data received from the portable game machine 50. .

  FIG. 18 shows a memory map of the ROM 601 of the game cartridge 60. The ROM 601 stores various movement programs, various drawing programs, and other game processing programs as program data. The description of each movement program and each drawing program is omitted because it is clear from the description of FIG. Since the player object movement control process is always performed on the stationary game machine 20 side, the ROM 601 does not have a player object movement program. However, when the player object exists in the GBA world, the movement control process of the player object may be performed on the portable game machine 50 side. In this case, the ROM 601 also needs a program for moving the player object. Note that, in the movement program for the simple moving object in the GC world and the movement program for the simple moving object in the GBA world, as shown in FIG. 19, the definition data of the movement pattern is defined for each simple moving object.

  In addition, the ROM 601 stores the topographic object arrangement data in the GBA world, the coordinates of each fixed object in the GC world, and the coordinates of each fixed object in the GBA world.

  Further, the ROM 601 includes, as object image data, image data for player objects, image data for simple moving objects in the GBA world, image data for complex moving objects in the GBA world, image data for fixed objects in the GBA world, Stores image data for terrain objects in the GBA world.

  The ROM 601 also includes shadow image data for displaying a shadow of a player object, shadow image data for displaying a shadow of a simple moving object in the GC world, and a shadow of a complex moving object in the GC world as shadow image data. Shadow image data for display and shadow image data for displaying a shadow of a fixed object in the GC world are stored. Since the GBA world is a two-dimensional game world, these shadow image data are two-dimensional image data representing shadows.

  The ROM 601 also stores other data such as sound data.

  There is no GC world object in the GBA world displayed on the LCD 502 of the portable game machine 50, and only the shadow is displayed. Therefore, the ROM 601 stores object image data corresponding to each object in the GC world. Instead, shadow image data corresponding to each object in the GC world is stored.

  Since the player character goes back and forth between the GC world and the GBA world, the DVD 30 stores the polygon / texture data and shadow volume data of the player object, and the ROM 601 stores the image data and shadow image data of the player object. .

  FIG. 20 shows a memory map of the RAM 508 of the portable game machine 50. The RAM 508 has an area for storing a synchronization counter for synchronizing processing with the stationary game machine 20, and an area for storing a player object flag and a light flag received from the stationary game machine 20. Or an area for storing color palette data for changing the brightness of the game screen, an area for storing the coordinates of the player object received from the stationary game machine 20, and a movement pattern. An area for storing the coordinates of each simple moving object in the GC world, an area for storing the coordinates of each complex moving object in the GC world received from the stationary game machine 20, and each simple moving object in the GBA world Of the area for storing the coordinates of each of the complex moving objects in the GBA world Area for storing the target is ensured appropriately.

  In addition, an area for storing operation data output from the operation switch 501 based on the player's operation is appropriately secured in the main memory 207.

  Next, processing executed by the CPU 201 of the stationary game machine (GC) 20 will be described with reference to the flowcharts shown in FIGS. In FIG. 21, first, initial setting is performed. Specifically, the main memory 207 is cleared, and then the synchronization counter shown in FIG. 17 is cleared. Since the player object exists in the GC world at the start of the game, the player object flag is set in the GC world, the light flag is set in the GC world, and the light color is normally set (S101). When the initial setting is completed, communication processing with the portable game machine (GBA) 50 is performed (S102). In this communication, a synchronization counter, a player object flag, a light flag, the coordinates of the player object, and the coordinates of each complex moving object in the GC world are transmitted to the portable game machine 50, while the portable game machine 50 receives operation data, The coordinates of each complex moving object in the GBA world are received. In this game system, the value of the synchronization counter incremented on the stationary game machine 20 side is transmitted to the portable game machine 50 side through the above communication processing, and the portable game machine 50 is based on the value of this synchronization counter. Game processing. In this way, the game counter 20 is shared between the stationary game machine 20 and the portable game machine 50, so that game processing is performed based on the value of the synchronization counter independently counted in each game machine. In this way, it is possible to more reliably prevent a shift in processing timing between game machines.

  When the communication process is completed, it is determined whether or not the player object flag is set in the GC world in FIG. 22 (S103).

  As a result of the determination in step S103, if the player object flag is set in the GC world, the player object existing in the GC world is moved based on the operation data received in step S102 (S104). As a result, it is confirmed whether or not the condition for the player object to move to the GBA world is satisfied (S105). This can be confirmed, for example, by determining whether or not the player character has stepped on the ladder floating in the air shown in FIG. As a result of the confirmation in step S105, if the condition for the player object to move to the GBA world is satisfied, the Y coordinate of the player object is updated to -10, the player object flag is updated to the GBA world, and the light flag is set. After updating to the GBA world and updating the light color to darker (S106), the process proceeds to step S110. On the other hand, as a result of the confirmation in step S105, if the condition for the player object to move to the GBA world is not satisfied, the process proceeds to step S110 without updating the flag or the like.

  On the other hand, if the result of determination in step S103 is that the player object flag is set in the GBA world, the player object existing in the GBA world is moved based on the operation data received in step S102 (S107). As a result of the processing, it is confirmed whether or not a condition for the player object to move to the GC world is satisfied (S108). This can be confirmed, for example, by determining whether or not the player object overlaps with a ladder object for going up to the GC world in the GBA world. As a result of the confirmation in step S108, when the condition for the player object to move to the GC world is satisfied, the Y coordinate of the player object is updated to 0, the player object flag is updated to the GC world, and the light flag is set to GC. After updating to the world and updating the light color to normal (S109), the process proceeds to step S110. On the other hand, as a result of the confirmation in step S108, if the condition for the player object to move to the GC world is not satisfied, the process proceeds to step S110 without updating the flag or the like.

  In step S110, the CPU 201 moves the simple moving object in the GC world according to the movement pattern definition shown in FIG. Subsequently, the movement destination of the complex moving object in the GC world is calculated to move the complex moving object in the GC world (S111), and the simple moving object in the GBA world is moved according to the movement pattern definition shown in FIG. S112).

  When the movement process of each object is completed, it is determined whether or not the player object flag is set in the GC world in FIG. 23 (S113). If the player object flag is set in the GC world, the camera is turned on. As shown in FIG. 8, the player object is placed diagonally above and below (S114). On the other hand, if the player object flag is set to the GBA world, the camera is placed diagonally below and behind the player object as shown in FIG. (S115).

  Subsequently, it is determined whether or not the light flag is set in the GC world (S116). If the light flag is set in the GC world, the light is tilted upward and backward as shown in FIG. On the other hand, if the player object flag is set in the GBA world, the light is arranged obliquely below and behind the player object as shown in FIG. 12 (S118).

  When the installation of the camera and the light is completed, it is determined whether or not the player object flag is set in the GC world (S119). If the player object flag is set in the GC world, the player object is displayed in the color buffer 205. (S120), each object in the GC world (simple moving object, complex moving object, fixed object, terrain object) is drawn in the color buffer 205 (S121). On the other hand, if the player object flag is set in the GBA world, each object in the GC world is drawn in the color buffer 205 without drawing the player object (S121). When each object in the GC world is drawn in the color buffer 205, the Z buffer 206 is used as appropriate.

  When drawing of each object in the GC world is completed, it is determined whether or not the light flag is set in the GBA world (S122).

  If the result of the determination in step S122 is that the light flag is set in the GBA world, the shadow of each object (simple moving object, complex moving object, fixed object) in the GBA world is drawn in the color buffer 205, and the result The obtained image data is output to the TV monitor 10 (S123). Here, when the player object is in the GBA world, the shadow of the player object is also drawn. The shadow drawing process in step S123 is performed by the method shown in FIG. The coordinates of the simple moving object in the GBA world are obtained by the moving process in step S112, the coordinates of the complex moving object in the GBA world are obtained by the receiving process in S102, and the coordinates of the fixed object in the GBA world are DVD30. Are stored in advance, and the coordinates of the player object are obtained by the movement process of step S104 or step S107.

  On the other hand, if the light flag is set in the GC world as a result of the determination in step S122, the shadow of each object (simple moving object, complex moving object, fixed object) in the GC world is drawn in the color buffer 205, The resulting image data is output to the TV monitor 10 (S123). Here, when the player object is in the GC world, the shadow of the player object is also drawn.

  When the shadow drawing in step S123 or step S124 is completed, game processing other than the game image generation processing such as battle processing is performed (S125), and then it is determined whether or not the game is over (S126). When the game is finished, the process of the CPU 201 is finished. When the game is continued, the synchronization counter is incremented (S127), and the process returns to step S102.

  Next, processing executed by the CPU core 506 of the portable game machine 50 will be described with reference to the flowcharts shown in FIGS. In FIG. 24, initial setting is first performed. Specifically, the RAM 508 is cleared, then the synchronization counter shown in FIG. 20 is cleared, the player object flag is set to the GC world, the light flag is set to the GC world, and the color palette is set to dark ( S201). When the initial setting is completed, communication processing with the stationary game machine (GC) 20 is performed (S202). In this communication, a synchronization counter, a player object flag, a light flag, the coordinates of the player object, and the coordinates of each complex moving object in the GC world are received from the stationary game machine 20, while the stationary game machine 20 Data and coordinates of each complex moving object in the GBA world are transmitted.

  When the communication process is completed, in FIG. 25, the CPU core 506 moves the simple moving object in the GC world according to the movement pattern definition shown in FIG. 19 (S203). Subsequently, the GBA world simple moving object is moved according to the movement pattern definition shown in FIG. 19 (S204), and the destination of the GBA world complex moving object is calculated to move the GBA world complex moving object. (S205).

  When the movement process of each object is completed, it is determined whether or not the player object flag is set in the GBA world (S206). If the player object flag is set in the GBA world, the color palette is set to normal. After that (S215), the player object is drawn in the color buffer secured in the RAM 508 (S207), and then each GBA world object (simple moving object, complex moving object, fixed object, terrain object) is drawn in the color buffer. (S208). On the other hand, if the player object flag is set in the GC world, the color palette is set dark (S216), and then each object in the GBA world is drawn in the color buffer (S208).

  When the drawing of each object in the GBA world is completed, it is determined whether or not the light flag is set in the GC world (S209).

  If the light flag is set in the GC world as a result of the determination in step S209, the shadows of the simple moving object and the complex moving object in the GC world are drawn in the color buffer (S210). At this time, as shown in FIG. 9, the size of the drawn shadow image is changed according to the Y coordinate of each moving object. When the player object is in the GC world, the shadow of the player object is also drawn. Note that the coordinates of the simple moving object in the GC world are obtained by the moving process in step S203, and the coordinates of the complex moving object and the player object in the GC world are obtained by the receiving process in step S202. When the drawing of the shadow of the moving object is completed, the shadow of the fixed object in the GC world is drawn in the color buffer, and the resulting image data is output to the LCD 502 (S211), and the process proceeds to step S212. Note that the coordinates of fixed objects in the GC world are stored in the ROM 601 in advance.

  On the other hand, as a result of the determination in step S209, if the light flag is set in the GBA world, the process proceeds to step S212 without drawing a shadow.

  In subsequent step S212, game processing other than game image generation processing, such as battle processing, is performed, and then it is determined whether or not the game has ended (S213). If the game has ended, the processing of CPU core 506 is performed. End and return to step S202.

  As described above, according to the present embodiment, since the shadow of the object existing in one world is displayed in the other world, the player can easily determine the relative positional relationship of the objects existing in each world. I can grasp it.

  Moreover, since the position of the object existing in the other world is represented by the shadow, the relative positional relationship of the object existing in each world can be displayed more clearly without impairing the reality.

  In addition, when displaying the shadow of an object that exists in another world, the destination of the movement is predicted based on the movement pattern of the object, so there is no need to acquire the coordinates of the object by communication, The amount of communication between portable game machines is reduced.

  In this embodiment, for example, the shadow of an object existing in the GC world is displayed in the GBA world. However, the present invention is not limited to this, and it is only necessary to be an image related to the object. For example, an image in which an object in the GC world is translucent (for example, an image in which a player object is translucent like a ghost) may be displayed in the GBA world. Also in this case, the player can easily grasp the relative positional relationship of the objects existing in each world based on the translucent image. Of course, a semi-transparent shadow may be displayed. In order to display such a translucent image, for example, a translucent image is stored instead of the shadow image data stored in the ROM 601 of the portable game machine 50, and the translucent image is displayed, for example, in FIG. It may be arranged in the GBA world by the method shown in FIG.

  Moreover, although this embodiment demonstrated the case where a light was a point light source, this invention is not limited to this, You may make it display a shadow based on parallel light.

  In the present embodiment, the positional relationship between the GC world and the GBA world is the relationship between the upper layer and the lower layer. However, the present invention is not limited to this, and the two worlds are in contact with each other at the same height. The positional relationship may be as follows.

  In this embodiment, the shadow of an object existing in the 3D GC world is displayed in the 2D GBA world, or the shadow of the object existing in the 2D GBA world is displayed in the 3D GC world. The present invention is not limited to this. For example, the shadow of an object existing in the three-dimensional game world may be displayed in the same three-dimensional game world.

  In the present embodiment, the program (movement program or drawing program) executed in the stationary game machine (GC) 20 is supplied from the DVD 30, but the present invention is not limited to this. For example, it may be supplied from any other computer-readable recording medium such as a CD-ROM or a game cartridge, or may be stored in the stationary game machine 20 in advance, and further appropriately from outside by communication. It may be supplied. Moreover, although the program (movement program and drawing program) executed in the portable game machine (GBA) 50 is supplied from the game cartridge 60, the present invention is not limited to this. For example, it may be supplied from any other computer-readable recording medium such as a CD-ROM or DVD, or may be stored in advance in the portable game machine 50, and further supplied from the outside appropriately through communication. It doesn't matter.

  In this embodiment, the portable game machine is used as the controller of the stationary game machine. However, the present invention is not limited to this. For example, a controller having a liquid crystal screen may be used instead of the portable game machine. Absent. Further, a plurality of stationary game machines may be connected instead of providing a stationary game machine and a portable game machine. In addition, it is not essential for the game system to include two independent game machines. For example, the present invention can be applied to an arcade game machine having two display screens.
