FIG. 7 is a schematic diagram showing an example of a display screen during the save process shown in FIG. When the player opens a menu on the display screen of the output device 2 and selects "save" in the menu (see FIG.
Is a display screen, 21 is a menu, CU is a cursor (operated according to an input signal of the controller 35), and the control unit 31 starts a save process.

First, the control unit 31 determines whether the player has selected the RAM 32 (internal memory) or the memory card 41 as a data save destination (step S101). In the following description, data is stored in the RAM 3
2 is referred to as "quick save". If the quick save is selected, the control unit 31 displays a predetermined message on the display screen 20, for example, "Quick save. Caution! Data is lost when the main unit is turned off. Yes No Is displayed (step S102).

Then, when the player selects "Yes" (step S103), the save data 32s in the above-described format is created in the work and is artificially saved in the save data storage area 32c (step S104), and the process ends. I do. Therefore, the save data storage area 32c is an area for pseudo-saving save data (pseudo save area).
It has become. On the other hand, when the player interrupts the execution of the quick save (step S103), the control unit 31 terminates the processing as it is.

Here, "simulated saving" means that the control unit 31 creates the save data 32s from the beginning by using the save data storage area 32c as a work area. The created save data 32s is renewed. The save operation of copying or moving to the area is not required. That is, when the creation of the save data 32s is completed in the save data storage area 32c, the data saving to the save data storage area 32c is completed. The game apparatus 3 may be configured such that the control unit 31 creates the save data 32s using an area other than the save data storage area 32c and copies or moves the save data 32s to the save data storage area 32c. Good. Or,
After the control unit 31 creates the save data 32s in the work area of the RAM 32, the game device 3
A configuration in which the area storing 2s is secured as the save data storage area 32c may be adopted.

When the player selects the memory card 41 as a data save destination (step S10).
1) The control unit 31 monitors the input of the cancel button until the player selects the memory card 41 whose data is to be saved from the plurality of memory cards 41. When the player inputs the cancel button (step S105), the control unit 31 ends the processing as it is. On the other hand, when the player selects the memory card 41 to be saved (strictly speaking, a slot in which the memory card 41 is inserted) (step S106), the control unit 3
1 checks whether the memory card 41 is inserted in the corresponding slot (step S107).

If the memory card 41 is loaded, the control section 31 checks whether the memory card 41 is formatted in a predetermined format (step S108). If the data has been formatted (step S109), the control unit 31 checks the data in the memory card 41 (step S110).
If data of the same game as the game being executed by the player has already been stored in the memory card 41 (step S111), the player overwrites the stored data with new data in the game, or Can be newly selected in the storage area.
When performing overwriting (step S112), the control unit 3
1 creates save data in the save data storage area 32c as in the case of the quick save described above (step S113), copies it to the memory card 41, that is, saves it, and ends the processing (step S1).
14). During the save, as shown in FIG.
Then, a message 23 indicating that the data is being saved in the memory card 41 is displayed. On the other hand, when not overwriting,
The process returns to the input monitoring state of the cancel button in step S105, and the subsequent processing is repeated.

In step S111, the memory card 41
If the data of the same game is not stored in the memory card 41, the control unit 31 checks a free area of the memory card 41 (step S115). And memory card 4
If there is a sufficient free area in step 1 (step S116) and the player selects execution of a new save (step S117), the control unit 31 creates save data in the save data storage area 32c in step S113. In step S114, it is copied to the memory card 41, that is, saved, and the process ends.

If there is not enough free space in the memory card 41 in step S116, if the execution of the new save is interrupted in step S117, if the memory card 41 to be saved is not inserted in step S107,
If the memory card 41 is not formatted in step S109, the control unit 31 displays a corresponding message, returns to the input monitoring state of the cancel button in step S105, and repeats the subsequent processing.

FIG. 10 is a flowchart showing an example of an item display process executed when the player plays the game following the soft reset. Here, the soft reset is an initialization operation performed when the game is restarted without inputting the reset button while the power is turned on after the end of the game by the program, that is, after the game is over. By the soft reset, the RAM 32
Areas other than the save data storage area 32c are erased.
That is, the save data 32s remains held. On the other hand, if the player performs a hard reset by turning off the power of the game device 3 and then turning it on, or by inputting a reset button or the like of the game device 3, the data stored in the RAM 32 is All will be erased.

When the soft reset is executed, the control unit 3
1 is the save data 3 from the save data storage area 32c.
2s is read (step S201), and the recognition character 32t is read.
Is checked (step S202). That is, in the example described above, the control unit 31 checks whether the tenth byte data from the upper byte of the save data 32s corresponds to the character “A”. If the recognized character 32t is correct (step S203), the control unit 31 counts the total number of bytes of the save data 32s (step S20).
4) Compare the number of bytes stored in the checksum 32u added to the end of the save data 32s (step S205).

As a result of the comparison, if the two match (step S206), the control unit 31 determines that the regular save data 32s quick-saved by the player during the previous game is stored in the save data storage area 32c. do it,
As shown in FIG. 11, on the display screen 20, an item 24 "New Game" indicating that a new game is started, and "Load Ga" indicating that save data is read from the memory card 41 and the game is continued.
me ”and an item 26 of“ QuickStart ”, which means that the data saved in the RAM 32 is read out and the game is continued, is terminated, and the process is terminated (steps S207, S208, S208).
209). If the recognized character 32t is not correct in step S203, or if the total number of bytes of the save data 32s does not match the checksum 32u in step S206, the control unit 31 returns to the display screen 20 as shown in FIG.
Display the items 24 and 25 of “New Game” and “Load Game”, and terminate the process (step S
210, S211).

FIG. 13 is a flow chart showing an example of processing for expanding data saved in the RAM 32 or the memory card 41. When a quick start is selected by the player (step S301), the control unit 31
The save data 32s stored in the save data storage area 32c is expanded, and various data in the save data 32s is allocated to each area of the RAM 32. As a result, the game data that was previously quick-saved is restored. Then, the control unit 31 starts the game program and ends the process (step S311).

On the other hand, if the quick start is not selected, the control unit 31 continues to input the cancel button until the player selects the memory card 41 from which data is to be read out of the plurality of memory cards 41. Monitor. When the player inputs the cancel button (step S302), the control unit 31 ends the process. On the other hand, when the player selects the memory card 41 to be read (strictly speaking, the slot in which the memory card 41 is inserted) (step S303), the control unit 31 determines whether the memory card 41 is inserted in the corresponding slot. Is checked (step S30).
4).

If the memory card 41 is loaded, the control section 31 checks the data of the memory card 41 (step S305).
If one or more data of the same game as the game that the player is trying to execute is already stored (step S306), for example, the saved data is saved so that the player can identify the individual saved data. Items that specify save data, such as a date and the name of a character serving as a hero (named by the player), are displayed on the display screen of the output device 2 (step S307).

Subsequently, the control unit 31 monitors the input of the cancel button until the player selects the save data to be read (step S308). When the player selects the save data to be read (step S309), the control unit 31 reads the selected save data from the memory card 41, and reads the saved data from the RA.
It is stored in the save data storage area 32c of M32 (step S310). Then, the control unit 31 determines in step S3
In step 11, the game data is restored by expanding the save data stored in the save data storage area 32c, the game program is started, and the process ends.

If it is determined in step S304 that the memory card 41 to be read is not loaded,
If there is no save data of the same game in 6, the control section 31 displays a corresponding message on the display screen, returns to the input button monitoring state of the cancel button in step S 302, and repeats the subsequent processing. Also, when the cancel button is input in step S308, the process returns to step S302, and the subsequent processes are repeated.

According to the above-described embodiment, when the player saves the game data, the save destination is R.
