There are various genres such as LG (Simulation Game) and adventure games (hereinafter, ADG; Adventure Game).

The above-mentioned games are rarely performed from the start of the game to the end of the game at once. Generally, the game is interrupted in the middle of the game and the progress of the game until the interruption is recorded in a memory or the like (save). When the game is played again, the progress of the game stored in the memory is read out, and the game is restarted from the state after the interruption.

For example, a role playing game (RP
In a game, such as G), in which the game proceeds according to a given story, it takes a considerable amount of time to achieve the game. For this reason, recently, game devices provided with a detachable external memory have appeared. By storing the progress in the external memory, the trouble of starting the game from the start can be saved, and the game can be advanced without loss.

[0006] In games such as RPG, shooting, and racing, there are data (parameters, scores, records, etc.) acquired as the game progresses. These data can also be stored in the external memory as in the course of the process described above.

FIG. 5 is a diagram showing a detailed configuration of the character data table 150 developed in the related data storage area 104b of the main memory 104 in the present embodiment. The character data table 150 is a data table that stores information about the own character.

The character data table 150 of this embodiment stores the “name” assigned to the character, the numerical data of the “level” and “experience” of the current character, and the “state” of the character at the current time. Status data, numerical data of “maximum HP”, “current HP”, “attack power”, “defense power”, “quickness” and “intelligence”, which constitute “ability value”, and information on “owned items” Is stored.

Before describing each item of the character data table 150, an outline of the game will be described. This game is a game in which a player operates his own character to search various places, search for hidden treasures, and exterminate monsters. At the time of the search activity, a battle is fought with a large number of enemy characters wandering around each place according to a predetermined rule. The own character gains experience gained by this battle, and the level and various ability values gradually increase.

In this game, when the player character encounters an enemy character while searching each place, a battle is performed. Here, in the game according to the present embodiment, a desired character is selected from among actions such as attack, defense, use of an item, and runaway, and the player performs a battle.

At this time, the own character and the enemy character alternately act, and if one of them becomes impossible to battle, the battle ends. When the enemy character becomes unable to battle and the battle ends, a value corresponding to the strength of the enemy character is added to the “experience value” of the own character. However, when the player character becomes unable to battle, "game over" is displayed, and the game is terminated halfway.

FIG. 6 is a diagram showing a detailed configuration of the state table 151 developed in the related data storage area 104b of the main memory 104 in the present embodiment. As shown in the figure, the items of the state table include “FINE”,
There are “DEATH”, “POISON”, “STONE” and “PARALYSIS”. “FINE” is a normal state, and does not change anything for the own character. “DEATH” is a state in which “current HP” has become 0 and a battle cannot be performed. In this state, the game ends in the middle. “POISON” is a state in which the own character has been poisoned.
The value of / 20 is subtracted from "current HP". "STON
"E" indicates that the character is petrified, and "PARALY"
“SIS” indicates a state in which the own character is paralyzed, and no action can be performed until the state is cancelled.

The items in the character data table 150 that affect the battle include the “state” in which the items in the state table 151 are entered, and the numerical values and possessed item items that make up the ability value. “Max HP” represents the maximum vitality of the own character, and “Current P” represents the current vitality of the own character. When the “current HP” becomes 0, the game is terminated halfway, but this numerical value can be returned to the “maximum HP” numerical value by using an item or the like. “Attack” is “Defense” when attacking an enemy character.
Affects when attacked by an enemy character.
Specifically, the higher the numerical value of the “attack power”, the earlier the enemy character can become incapable of fighting, and the higher the numerical value of the “defense power”, the higher the “current H” when the enemy character is attacked.
It is difficult for the numerical value of "P" to decrease. The “quickness” is a numerical value for determining which of the enemy character and the own character can act first, and the higher the value, the higher the probability of escape. "Intelligence" has an effect when using an item, and the higher the value, the greater the effect obtained.

The possessed item indicates an item obtained by the own character during the game, and the item can be used as many as the possessed item. Some items remove or disable poisons, petrification, and paralysis in the "state", and can be used effectively to make the battle more advantageous. In the character table, these items, a "name" that can be arbitrarily determined by the player at the start of the game, and a "level" and "level" indicating the current strength of the character are displayed in a stepwise manner. There is "experience value" which is a numerical value to increase.

As the game proceeds, the “level” increases based on the “experience value”, and the numerical value of each item of the “ability value” increases. Also, the number of possessed items increases.
In the present embodiment, this character data table is recorded as the progress of the game. If the recorded character data table is read when the game is restarted, the game can be played with the previous play result reflected.

Next, the control of storing game data in the memory card 55 and the control of restarting the game by loading game data from the memory card when the game is interrupted according to the present embodiment will be described.

First, FIG. 7 shows a format of the game data saved in the memory card in the present embodiment. In FIG. 7, reference numeral 901 denotes a 128-byte header area, and 902 denotes a magic area. For example, "SC" is stored in the header area.

Reference numeral 903 denotes a 1-byte type designation area for designating the type of data. As shown in detail on the right, 903a (0 ×
11), the number of the automatic replacement icon images is two 90
3b (0 × 12), and three types of 903c (0 × 13) having three types of automatic replacement icon images can be designated.

Reference numeral 904 denotes a 1-byte slot number storage area;
Reference numeral 905 denotes a 64-byte document name storage area.
It is possible to specify two non-kanji and first-level kanji. 906 is a 28-byte pad (pa
A d) area 907 is a 32-bit CLUT (color look-up table) area.

Reference numeral 910 denotes an icon image storage area in which icons of the number of icon images designated in the type designation area 903 can be stored. The capacity of the icon image is 128 bytes (16 × 16 × 14 bits). This icon image is shown in FIG.
Is icon data corresponding to the icon data stored in the icon data storage area 54e shown in FIG.

The above-mentioned parts constitute the header part of the game data, and the constitution of the header part is standardized by the game machine. Then, following this header portion, specific save data of an arbitrary length indicated by 950 is stored.

The format of the graphic data of the icons stored in the icon image storage area 910 according to the present embodiment will be described below. Icon image (1) in icon image storage area 910 of the present embodiment
The relations (2) and (3) correspond to the number of graphics used for the icons.

If the icon is a single picture without animation, only the icon image (1) is used, and the icon images (2) and (3) are not used. At this time, the layout of the data saved in the memory card 55 is such that the game data 95 is added after the data of the icon image (1).
It becomes 0.

On the other hand, if the icon is animated using three pictures, the icon image (1)
The icon images are stored in all of (2) and (3). In this case, the icon images (1) and (2)
The data of (3) are arranged in order, followed by the game data 9
50 are arranged, and the amount of save data increases by 256 bytes as compared with the case where only the icon image (1) is used.

In the game system of the present embodiment, one icon image (graphic data) is always required to be stored in the icon image storage area 910, and as a part of the header of the save data file,
Regardless of the state, it is recorded together with the game data 950 on the memory card.

The format of the game save data of the present invention is not limited to the above example. Information specifying the game stored in the CD-ROM 54 in the game save data, for example, icon data or character data Any format can be used as long as the format includes the graphic data or the like in the save data.

The save to the memory can be performed by moving the game data to a place where the game data can be saved during the game, or by selecting save when a scene is encountered. You can arbitrarily select and select game save.

On the game save screen (memory management screen) in the actual game system, if there is game data that has already been saved in the past, for example, the icon image stored in the icon image storage area 910 and the last A summary of the data when the game was saved is also displayed. Therefore, if the game is to be restarted, save data for restarting the game is confirmed and selected on the icon display and the summary display of the game data, and the selected game data is loaded to restart the game.

The details of the game restart processing of the present embodiment will be described below with reference to the flowchart of FIG. FIG. 8 is a flowchart showing the game restart processing of the present embodiment.

Here, the display screen of the monitor display 56 is a selection screen for selecting whether to start the game from the beginning or to read the saved game data and continue the game.

The gamer operates the controller 53 to select “start” for executing the game from the beginning, or
The user has to select and input whether to restart the interrupted game. If there is a selection input, the process proceeds to step S2, and it is determined whether or not the input is a restart instruction input of the interrupted game. If it is not an instruction to restart the interrupted game, step S3
The game is started from the beginning without saving the game data from the memory card 55.

If it is determined in step S2 that the instruction to restart the interrupted game has been input, the flow advances to step S4 to search whether the memory card 55 is inserted. Then, in step S5, as a result of the search, the memory card 5
If 5 is not mounted on the game device 52, for example, a message prompting the user to mount the memory card 55 is output, and the process returns to step S1.

At the judgment of step S5, the memory card 55
If the CD-ROM is mounted, the process proceeds to step S6, and the CD-
CD-ROM set in ROM drive 113
It is checked whether there is save data corresponding to the game program stored in 54. If there is no save data corresponding to the game program stored in the CD-ROM 54 set in the CD-ROM drive 113, a message indicating that there is no save data corresponding to the game program to be executed is output. And returns to step S1.

At step S7, the CD-ROM drive 1
If there is save data corresponding to the game program stored in the CD-ROM 54 set in 13, the process proceeds to step S8, where the game data is read out and displayed on the screen of the monitor display 56. The display data at this time is a display of game data stored in the format shown in FIG. 7, and includes an icon display, a state display at the time of restarting the game, and the like. When a plurality of game data are stored, the stored game data is sequentially displayed.

The gamer confirms the icon display and the state display at the time of resuming the game, operates the controller 53 to select game data to be restarted, and inputs an instruction to restart the game. Therefore, step S
In step 9, the game waits for selection of game data to be restarted by operating the controller 53. When the game data to restart the game is selected, the process proceeds from step S9 to step S10.
Then, the icon image of the icon image storage area 910 in the game save data of the selected memory card 55 is compared with the icon image stored in the icon data storage area 54e of the CD-ROM 54.

In step S11, step S10
Examine the results of the comparison in. If the image data corresponding to the icon image in the icon image storage area 910 of the memory card 55 is stored in the icon data storage area 54e of the CD-ROM 54, step S12 is performed.
Proceed to. Then, the game is started from a scene corresponding to the game data stored in the game data area 950.

On the other hand, in step S11, the image data corresponding to the icon image in the icon image storage area 910 of the memory card 55 is stored in the CD-ROM 54.
If the game data is not stored in the icon data storage area 54e, the game data in the memory card 55 is not the data saved by normally proceeding the game, but the falsified game data. Proceeding from S11 to step S13, the game is forcibly ended instead of restarting the game in accordance with the selected game data, and the game restart is stopped because, for example, when this data is loaded, an unexpected operation may occur. Output a message indicating that

Note that C, which is a part of the graphic data,
If the check of the LUT (32 bytes) is also performed, the start of the game can be effectively prevented even in the case where the color is changed and the device is misleading.

Although the game is forcibly terminated in step S13, the game may be started from the beginning by invalidating the game data instead of restarting the game in accordance with the selected game data. Unless the selected game data is valid and the game is started, various operations can be performed.

In the present embodiment, since the control is performed as described above, it is possible to prevent the game from being resumed by reading the falsified save data, and it is possible to prevent the falsified save data from being distributed to general users. Even in this case, it is possible to effectively prevent the user from resuming the game based on the falsified data, and to call attention.

Next, the game data saving process according to the present embodiment will be described with reference to the flowchart of FIG. When saving a game, the display of previously saved game data and the like is checked, a save location is selected, and the save is performed at the selected location.

If the controller 53 is operated during the execution of the game, the flow shifts to the processing of FIG. 9, and in step S51, is the operation instruction of the controller 53 input to the save screen (memory management screen) under the condition that the save can be performed. Check whether or not.
If it is not an input of an instruction to shift to the save screen (memory management screen) under conditions that allow saving, the process proceeds to step S52,
The corresponding process is executed to advance the game.

When the user's character arrives at a position at which the game can be saved in the game being executed, or when the character can be saved, the controller 53 can be operated to shift to a memory save screen (memory management screen). Become. Therefore, when the controller 53 is operated in such a situation to instruct transition to the memory save screen (memory management screen), the process proceeds from step S51 to step S53. Then, in step S53, a search is made as to whether the memory card 55 is inserted. Then, in step S54, as a result of the search, it is determined whether or not the memory card 55 is mounted on the game apparatus main body 52.

If it is determined in step S54 that the memory card 55 is not mounted on the game device main body 52, the process proceeds to step S54.
Proceeding to 55, for example, a message prompting the user to insert the memory card 55 is output. Then, it is checked whether or not an input to the effect that the setting has been made in step S56. If there is no input indicating that the setting has been made, the process proceeds to step S57, and it is determined whether or not save cancellation has been input. If the save cancellation has not been input, the process returns to step S56, and waits for an input indicating that the setting has been performed by operating the controller 53 or an input for canceling the save.

In this state, if there is an input indicating that the memory card has been set, the process proceeds from step S56 to step S53 to search for the memory card 55. On the other hand, when save cancellation is input, the process proceeds from step S57 to step S58, and the game progress is continued without saving the game data. Thereafter, when the controller 53 is operated, the processing shifts to the processing of step S51.

On the other hand, if it is determined in step S54 that the memory card 55 has been inserted, the process proceeds to step S60, where C is set in the CD-ROM drive 113.
It is checked whether there is save data corresponding to the game program stored in the D-ROM 54. And C
CD-R set in D-ROM drive 113
If there is save data corresponding to the game program stored in the OM 54, the game data is read out and displayed on the screen of the monitor display 56. on the other hand,
If there is no save data corresponding to the game program stored in the CD-ROM 54, a storable save area is displayed.

The gamer checks the displayed icon display and the previously saved game state display, selects a game data storage area to be saved, and inputs an instruction from the controller 53. Therefore, it is determined whether or not the game data storage area is selected and input in step S61. If there is no selection input of the game data storage area, the process proceeds to step S62, and it is determined whether or not save cancellation has been input. If save cancellation has not been input, the flow returns to step S61 to wait for selection input of a game data storage area or input of save cancellation by operating the controller 53.

In this state, if there is a selection input of the game data storage area, the process proceeds from step S61 to step S63,
A save process for generating the format shown in FIG. 7 and saving the format in the memory card 55 is performed. Here, game data 95 corresponding to the progress of the game at the time of the save instruction is given.
0 in the icon image storage area 910.
One or more icon images (graphic data) corresponding to the game data generated according to the progress of the game are always selected from the icon images stored in the icon data storage area 54e of the ROM 54, and the header data of the save data file is selected. As a part, it is recorded on the memory card 55 together with the game data 950. Then, the process returns to step S60.

On the other hand, when save cancellation is input, the process proceeds from step S62 to step S58, and the game progress is continued without saving the game data. Thereafter, when the controller 53 is operated, the processing shifts to the processing of step S51.

As described above, in the present embodiment, since reading of falsified save data is not accepted, a user who intends to falsify save data has no choice but to use the original save data. In the case where the part is falsified and distributed to general users, the maker can pay attention to the distributor.

As described above, since it is possible to prevent the game from being restarted by reading the falsified save data, it is possible to play happily according to the excellent story flow of the game software.
