It is a program such as detection. In the storage area 33i, touch panel operation state detection processing program data is stored. The touch panel operation state detection processing program reads coordinate data that changes according to the operation of the touch panel every short fixed time (for example, a frame) and temporarily stores the coordinate data, and relatively long fixed time (for example, several tens times the frame period to Detects the change state of the coordinate data every several hundred times), and if the change of the coordinate data is the same (or substantially the same) repeated coordinate data, detects that it is an instruction to change the display coordinate position of the narrow range map image If the change in the coordinate data changes gradually and continuously, it is a program that detects that the movement direction is instructed based on the amount of change in the X-axis component and the Y-axis component. Further, the movement amount (scroll amount or distance) may be detected based on a vector amount obtained by synthesizing each change amount of the X-axis component and the Y-axis component.

The storage area 33j stores a program for determining whether the player object is present in the first display unit (LCD 11) or the second display unit (LCD 12). The result determined or determined by this determination program is temporarily stored in a part of the storage area (or address, generally called “flag area”) of the W-RAM 27. The temporary storage area for storing the determination result functions as state storage means, stores “0” when the player object is displayed on the LCD 11 side, and is not displayed on the LCD 11 side (displayed on the LCD 12 side). Is stored), by storing “1”, the display area in which the player object exists is stored and held.
Details of processing based on various programs stored in the storage areas 33a to 33j will be described with reference to FIGS.

FIG. 4 is a diagram schematically showing a game space for explaining the principle of the present invention. In particular, FIG. 4 shows game spaces and player objects to be displayed on an upper screen (LCD 11) and a lower screen (LCD 12) on a certain map (or stage) in a side-scrolling action game or role-playing game (RPG), respectively. It is a thing. Specifically, one map or stage includes two game spaces, which are a game space 41 wider than the display range of the upper screen (LCD 11) and a game space 42 wider than the display range of the lower screen (LCD 12). Including. The display ranges indicated by the thick lines of the game spaces 41 and 42 (one screen at the top and bottom of the left end in the illustrated state) are respectively displayed on the LCD 11 and the LCD 12, and as the player object 43 moves in the right direction, The displayed ranges on the game spaces 41 and 42 are gradually moved (scrolled) at the same speed. That is, in the game space 41 on the upper screen, auxiliary or preliminary course images (parts or blocks of courses) 412, 413, 414 are drawn in addition to the basic course image 411 extending in the horizontal direction. In any place of the course image 411 or the preliminary course images 412 to 413 , a passage image (a communication passage that is conditioned so that the player object 43 can come and go (or freely come and go) to the other game space 41) In the example shown, a clay pipe) 415.416, 417 is drawn. When the player object 43 moves on the course image 411, the player object 43 advances the course while avoiding the attack of the enemy object 44 a, and clears the course while acquiring various items 418 that are appropriately displayed in the course image 411.

  When the player object 43 wants to move to another game space 42, the player object 43 is placed on the passage image (earthen pipe) 415 to 417 and an operation switch (for example, 15L) instructing to proceed to another game space 42 is operated. Thus, the condition is set so that it can be moved. The game space 42 is drawn such that the course image 421 extends in the horizontal direction, and a passage image (earthen pipe) that is conditioned so that it can go to the game space 41 at coordinate positions corresponding to the passage images (earthen pipes) 415 to 417 425-427 are drawn. Like the game space 41, the game space 42 can display items 428 and non-player objects (enemy objects) 44b, but when the player object 43 does not exist (in other words, the player object 43 exists in the game space 41). At least one of the course image 411, the item 428, and the non-player object 44b, and at most two images are displayed. The reason is that a background image or a non-player object of the game space 42 in which the player object 43 does not exist (in contrast, if the game space 42 in which the player object 43 exists is the lower game space 42) is displayed. By not doing so, the player's curiosity is stimulated, and the player is encouraged to move to a game space different from the current game space or to exhibit unexpectedness. Further, when the player object moves in the game space, the display state is changed in an unpredictable manner in the moved game space, so that the other game is cleared even after the map or stage is cleared using the one game space. Using the space, you can play again with new feelings.

FIG. 5 is a diagram for explaining the display principle for realizing the game screen of FIG. As an example, the game space 41 and the game space 42 are configured by a plurality of screens (cells) for each of the game spaces 41 and 42 in a range to be displayed on at least the LCD 11 and the LCD 12, and a layer for displaying the player object 43. (Cell) is set with the highest priority, and is displayed on a background image lower than that. For the game space (for example, 41) where the player object 43 exists, images of all layers (cells) are displayed. Display processing is performed so as to combine and display based on the priority. On the other hand, for a game space in which the player object 43 does not exist (for example, 42), only the layer set by the program is selected and displayed from the layers (cells) storing the background image or the image of the non-player object. Display processing as follows. Specifically, when the program is set to display the course image, the layer (bottom cell) of the course image corresponding to the game space 42 in FIG. 5 is selected, and the item (eg, coin) image is displayed. When the program is set to be displayed, the item image layer (second cell from the bottom) corresponding to the game space 42 is selected, and when the program is set to display the enemy object, the game space 42 is selected. The layer (third cell from the bottom) of the enemy object image corresponding to is selected.
However, in each cell, data indicating that the area other than the player object 43, the enemy object 44b, the item image 428, and the course image 421 is displayed transparently (or nothing is displayed) is written in the cell. The image of the layer will be seen through.

  FIG. 6 shows a display example in which all the layers of the game space 41 are displayed on the LCD 11 which is the upper screen, and the course image layers of the game space 42 are displayed on the LCD 12 which is the lower screen.

  FIG. 7 shows a display example in which all the layers of the game space 41 are displayed on the LCD 11 which is the upper screen, and the course image layer and the item image layer of the game space 42 are combined and displayed on the LCD 12 which is the lower screen. In FIG. 7, only the item image layer of the game space 42 may be displayed on the LCD 12.

FIG. 8 shows a display example when the player object on the LCD 11 which is the upper screen moves from the game space 41 to the game space 42. In this case, the player object 43 disappears from the upper screen and appears on the lower screen. At that time, not only the course image (or item image) of the game space 42 but also the item image, enemy object, etc. Various images of all layers are combined and displayed. On the other hand, only the course image (and / or item image) is displayed in the game space 41 where the player object 43 disappears, and when the display screen scrolls as the game progresses, the game space 41 becomes a mysterious game image . , It can arouse the curiosity of the player and create a desire to return. When the player object 43 returns to the game space 41 again, the lower screen is displayed ambiguously as shown in FIG.
Next, the operation in the case of controlling the display of the game screen as shown in FIGS. 4 to 9 will be described in detail.

  10 and 11 are flowcharts of the two-screen display game device and the two-screen display game program according to one embodiment of the present invention. FIG. 12 is a flowchart of the key input processing subroutine. Next, with reference to FIGS. 1 to 12, a specific operation in the case of performing the display processing of the two-screen display game image of FIGS. 4 to 9 will be described.

When a power switch (not shown) is turned on, the CPU core 21 starts the following processing based on each program stored in the storage area 33 of the ROM 31. First, in step (abbreviated as “S” in the drawing) 11, initial processing is performed. As this initial processing, for example, after the W-RAM 27 and V-RAM 28 and 39 are initially cleared, the backup data stored in the RAM 35 (if played so far, the stage that was captured until the previous play) (Or map) number, experience value, progress data such as acquired item) are read out and written in a backup data storage area (not shown) of W-RAM 27. Also, a play start selection screen is displayed, and selection is made between starting from the first stage (number 1) or starting from the stage number following the previous play. In step 12, the selected stage number (stage number “1” when playing for the first time) is stored in the stage counter (or stage register; although not shown, a partial address of the W-RAM 27). In this way, the preparation process for starting the game play is performed.

In subsequent step 13, stage image data for the entire range of stage numbers stored in the stage counter (for example, the entire range of MAP shown in FIG. 3) is read from the ROM 31 and written to the W-RAM 27. In step 14, the coordinate data of the player object is set to an initial value. For example, the leftmost coordinate of the first stage image in the game space 41 displayed on the LCD 11 is written in a register (partial address of the W-RAM 27) that stores the coordinate position of the player object. Further, in step 15, a flag for determining the screen on which the player object exists is set to an initial value (for example, “0” indicating that it exists in the game space 41 on the upper screen).

  When a key input operation is performed by the player in step 16, it is determined in step 17 that any key input has been made, and key input subroutine processing is performed. This key input subroutine process will be described later with reference to FIG. Thereafter, the process proceeds to Step 18. When the player performs an input operation on the touch panel in step 18, it is determined in step 19 that the touch panel has been operated. In step 20, touch panel input processing is performed, and then the process proceeds to step 21. If there is no key input, it is determined in step 17 that there is no key input, and the process proceeds to step 18 without processing the key input subroutine. If there is no touch panel input, it is determined in step 19 that there is no touch panel input, and the process proceeds to step 21 without performing touch panel input processing.

And in the non-display period of LCD11 and LCD12, the process of steps 21-27 is performed. I sand, in step 21, it is judged whether or not the non-display period of the LCD11 and LCD 12, when it is determined that a non-display period, in step 22, based on the course image display control program on the screen The CPU core 21 performs course image processing on the upper screen. In this process, since the CPU core 21 sets the coordinate position determined by the initial value and displays the course image for one screen from the coordinate position on the LCD 11, the coordinate of the upper left corner on the display screen of the LCD 11 is The coordinates of the game space 41 are set so as to have an offset value. Then, the course image data in the display range indicated by the thick line in the upper part of FIG. 4 is written in the course image cell area for one screen of the W-RAM. In step 23, based on the upper screen of the item image display control program, CPU core 21 performs an item image processing on the screen. In this process, the CPU core 21 sets the coordinate position determined by the initial value, and the item image to be displayed corresponding to the previously set course image range (display range indicated by the upper thick line in FIG. 4) is displayed. it is intended to write to the item image cell area of the W-RAM 27. Further, in step 24, the CPU 21 writes the non-player object image data in the non-player object image cell area of the W-RAM 27 in order to display the non-player object on the course image in the range of one screen.

Similarly, the course image processing of the lower screen is performed in step 25, the item image processing of the lower screen is performed in step 26, and the non-player object image processing of the lower screen is performed in step 27. In this manner, the W-RAM 27 individually stores the upper screen course image, item image, and non-player object image, and the lower upper screen course image, item image, and non-player object image. Will be.
In step 28, it is determined whether or not the stage clear condition has been reached. If it is determined that the stage has not been cleared, the process returns to step 16 and steps 16 to 21 are repeated.

If it is determined in step 21 described above that it is not the non-display period of the LCD 11 and the LCD 12 (that is, the display period), in step 29, the information stored in the W-RAM 27 at the display timing of the LCD 11 is displayed. The course image data and item image data on the screen are sequentially read and overwritten in the V-RAM 28. In step 30, the GPU 25 controls to read out the V-RAM 28, so that the course image data and item image data on the upper screen are sequentially read out in synchronism with the frame scanning in one frame period, and are combined and displayed on the LCD 11. The Similarly, in step 31, the course image data and item image data on the lower screen stored in the W-RAM 27 are sequentially read and overwritten in the V-RAM 28 at the display timing of the LCD 12. In step 32, the GPU 25 controls to read out the V-RAM 28, so that the course image data and item image data on the lower screen are sequentially read out in synchronism with the frame scanning in one frame period, combined and displayed on the LCD 12. The In step 33, it is determined whether or not the screen on which the player object 43 exists is an upper screen by determining whether or not the player object screen determination flag is 0. If it is determined that the screen is the upper screen, in step 35 , a non-player object is displayed on the upper screen. On the other hand, if it is determined that the screen is the lower screen, in step 34 , a non-player object is displayed on the lower screen . In this way, the screen for the presence of the player object, course image, item image, all non-player object is displayed on the screen in the absence of the player object, either or both courses image, item image (or It is possible to display only non-player objects).

  Thereafter, in step 28, it is determined whether or not the stage clear condition has been reached. If it is determined that the stage has not been cleared, the process returns to step 16, and the above-described steps 16 to 28, or steps 16 to 21, 29 are performed. The operations of .about.35 and 28 are repeated. If the stage clear succeeds during these operations, it is determined in step 28 that the stage clear condition has been reached. In step 36, the count value of the stage counter is incremented by 1, and image processing of the next stage is performed. .

Subsequently, in step 37 , it is determined whether or not the game is finished. The detection of the end of the game conditions, when the count value of the stage counter has reached the maximum stage number (N), or game over conditions (for example, a player hit points or life is "0") based on the fact that became It is detected Te. When it is detected in step 37 that the game end condition is not satisfied, the process returns to step 13 described above, and the operations of steps 13 to 28 or steps 13 to 21, 29 to 35, and 28 are repeated at a constant cycle.

Next, the process of the key input subroutine will be described with reference to FIG. In step 51, the coordinate position where the player object 43 is located is detected. In step 52, it is determined whether or not there is an input from the direction indicating switch 15a. If it is determined that there is an input, the process proceeds to step 53. If it is determined that there is no input, the process proceeds to step 58 described later. When there is an input from the direction indicating switch 15a, in step 53 , an operation state detection process of the direction indicating switch 15a, for example, “up”, “down”, “left”, or “right” of the direction indicating switch 15a is selected. If pressed, the key code corresponding to the operated “up”, “down”, “left”, “right” is read and temporarily stored in an internal register (not shown). In step 54 , a process for changing the current coordinate position of the player object based on the operation of the direction indicating switch 15a is performed. In step 55, it is determined whether or not the player object satisfies a condition for allowing the player screen to move between the upper screen and the lower screen. If it is determined that the screen movement condition is satisfied, it is determined in step 56 whether or not the player object has moved to another screen. If it is determined that the screen has moved to another screen, the player object screen determination flag is reversed in step 57.

Thereafter, in step 58, it is determined whether or not there is an input from the other switches 15b to 15f. If it is determined that there is an input from the switches 15b to 15f, an input process corresponding to the other switch is performed in step 59. Is done. Thereafter, or when it is determined that there is no input from the other switches 15b to 15f, the process returns to step 18. Thus, processing corresponding to the operation input of the direction switch 15a and its other switches 15b~15f is performed.

  In the above-described embodiment, the case of a horizontal scroll game program has been described. However, the technical idea of the present invention can also be applied to a vertical scroll game as shown in FIGS. The technical idea of the present invention is not limited to an action game, but can be applied to various genre games such as RPG, simulation RPG, and shooting game.

By the way, in each of the above-described embodiments, the case where two physically separated LCDs 11 and 12 are vertically arranged as an example of a liquid crystal display unit for two screens (in the case of two screens on the top and bottom) has been described. Except for the housing 13a, one housing 13c may be formed in a horizontally long shape so that the LCDs 11 and 12 for two screens can be accommodated in a left-right arrangement. In this case, considering that there are many right-handed users, the LCD 12 with the touch panel 16 attached is preferably arranged on the right side and the LCD 11 is arranged on the left side. However, when making a left-handed portable game device, the arrangement is reversed.
As another arrangement example, instead of a configuration in which two physically separated LCDs 11 and 12 are arranged above and below, a single vertically long LCD having the same horizontal width and a double vertical length (a In other words, by using a single LCD that has a vertical display size of 2 screens, a vertical LCD screen is arranged for 2 screens. May be displayed (that is, displayed adjacent to each other without upper and lower boundary portions). In addition, using a single horizontally long LCD with the same vertical width and double horizontal length, the stage images for two screens are displayed in the horizontal direction on the left and right (ie adjacent to each other without the left and right borders). Display).

A non-player object image generating step for generating a non-player object image that cannot be operated by the operating means in order to influence the player object existing in the first game space or the second game space;
A second side whose space range along the scroll direction is larger than the first side of the first display unit and whose space range perpendicular to the scroll direction is perpendicular to the first side of the first display unit; The first game image has a substantially equal first game space, and at least a first course image in which the player object is movable is sequentially changed along the scroll direction as a first game image in the first game space. A first passage image that allows the player object to move to the second game space is generated, and a first background image is generated by combining the first course image and the first passage image. Background image generation step,
A second side whose space range along the scroll direction is larger than the first side of the second display unit and whose space range perpendicular to the scroll direction is perpendicular to the first side of the second display unit; A second game image having substantially the same second game space, and as a second game image in the second game space, at least a second course image in which the player object is movable is sequentially generated along a scroll direction; A second path image that allows the player object to move to the first game space is generated, and a second background image is generated by combining the second course image and the second path image. Background image generation step,
An item image generating step for generating an item image displayed in the game space in which the player object exists and acquired by the player object;
The first background image generated in the first background image generation step is displayed on the first display unit, and the second background image generated in the second background image generation step is displayed as the second background image. Display control step to be displayed on the display unit,
The display control step further includes
Based on the determination result in the determination step, the background image of the game space in which the player object exists in the first game space and the second game space, the player object image, and the non-player In addition to the object image, the item image is combined and displayed on one display unit, and the background image of the other game space is displayed on the other display unit.
In response to determining that the player object has moved from the one game space to the other game space in the determination step, a background image of one game space is displayed on one display unit, and the other In addition to the background image of the game space, the player object image, and the non-player object image, the item image is synthesized and displayed on the other display unit.
