The present invention relates to a game device capable of playing game software that is narrowed down at the game software start stage and in which items different from other game machines appear with different probabilities while being the same game.
First, “items” are defined to mean props, animals, partners, etc. that can be randomly selected and obtained during the course of the game.
[0002]
[Prior art]
In a game machine that can be backed up, it is possible to use a game cassette of another person's game machine by attaching it to its own game machine. In such a case, it is interesting that items that cannot be obtained from each other can be complemented.
However, since the appearance rules of items are the same in the same program, there is a drawback that even if they are selected at random, all may appear and the value to be exchanged becomes low.
[0003]
[Problems to be solved by the invention]
As a method for solving this, a plurality of programs having different item appearance rules may be prepared. However, there are disadvantages in that the production efficiency is low and the risk of mass production is large.
The object of the present invention is to create a probability table for irregularly generating items that appear at the initial startup of game software of a game machine for one program, so that different contents while having the same type of game function. An object of the present invention is to provide a game apparatus capable of playing the game.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, a game device having a plurality of regularities according to the present invention comprises an irregular signal generating means for generating an irregular signal based on a predetermined operation of a player or a time display on a clock, and an item probability table. When the CPU reads and activates the game application software installed in the game machine main body when the power is turned on and stores the storage unit for storing, and determines that the item probability table does not exist in the storage unit, the irregular signal generating means Probability table creation means for creating an item probability table by replacing each probability of a plurality of items in a basic probability table prepared in advance by an irregular signal from the item, and an item probability table exists in the storage unit If, by chance based on the item probability table, based on the item probability tables created by the probability table creating means in the absence of It is configured to include a item appearance execution means for advancing a game by the appearance of the item by the rate.
Further, the storage unit in the present invention is backup memory means that can be attached to a game machine , and the predetermined operation of the player in the irregular signal generation means is from starting the game by turning on the power until pressing the game start button. The CPU checks the time from when the power is turned on until the game start button is pressed , and generates an irregular signal based on the time, or a predetermined operation by the player in the irregular signal generating means. is an operation to press the other buttons, or CPU checks the length of time that the pressing another button, generates an irregular signal with its time basis, or the random signal predetermined operation of the player in the development unit, the player is an operation for inputting a name, CPU will generate an irregular signal in the basis of the name input by the player It is those that are either of Luke.
Furthermore, the sum of the appearance probabilities of the items in the item probability table created by the probability table creating means in the present invention is a predetermined numerical value, and the item appearance executing means sets the items in the item probability table in a predetermined order. Select a difference between the probability of the selected item and a numerical value that varies irregularly between 0 and the predetermined value, and when the difference satisfies a predetermined condition, the item appears. If not satisfied, the next item is selected, the difference is similarly taken, and the item is made to appear by selecting the item successively until the predetermined condition is satisfied.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a game apparatus capable of creating game software with different item appearance contents according to the present invention, and is an external view of a portable game machine.
The portable game machine 1 has a cassette mounting hole 1a on the upper surface, and the game cassette 4 on which the program ROM 4a and the backup RAM 4b are mounted is mounted from this portion. The portable game machine 2 is similarly loaded with a game cassette 5.
The portable game machines 1 and 2 can be connected by a communication cable 3, and the two game machines can play a game while communicating with each other, and can complement each other item that cannot be obtained.
[0007]
The backup RAM 4b stores a probability table of appearance of items generated when the power is turned on for the first time to start the game software, and items in the game are caused to appear with reference to this probability table. Thereafter, the game program proceeds based on this item probability table. Accordingly, the probability tables generated by the portable game machines 1 and 2 are different, and a game can be played for the same program using different item appearance data. If the game cassettes 4 and 5 are exchanged, the game content of the opponent's item appearance can be realized with his / her portable game machine 1.
[0008]
FIG. 2 is a diagram showing a game apparatus capable of creating game software with different item appearance contents according to the present invention, and is an external view of a stationary game machine.
The stationary game machine 6 is configured to mount a cassette of the backup RAM 9 from the front. A CD-ROM 7 in which a game program is stored is mounted from above. When the CD-ROM 7 is mounted for the first time and the power is turned on, an item appearance probability table is generated and stored in the backup RAM 9.
[0009]
FIG. 3 is a block diagram showing an embodiment of a circuit of a game device capable of creating game software having different item appearance contents according to the present invention.
This circuit is the configuration of the portable game machine of FIG. A game program 18a and a large number of item data 18b are stored in the ROM 18 of the game cassette 15 that can be attached and detached. The backup RAM 19 stores save data 19a and an item probability table 19b.
FIG. 5 shows an example of the save data 1 and the item probability table.
The save data 19a is data necessary for playing the continuation of the game, and is updated by a player's operation or automatically.
The item probability table 19b is created only once at the start of the game, and thereafter the value does not change or disappear.
[0010]
The CPU 14 controls the entire game machine. When a game is started in accordance with an operation from the operation unit 17, the CPU 14 reads the game program 18 a and develops game data in the RAM 20, and the decompressed data is transmitted via the video circuit 21. It is displayed on the display unit 24. In addition, the sound circuit 22 is operated to send voice, music, etc. from the speaker 23.
The CPU 14 generates an irregular signal (random number) based on the player's operation when the power switch 16 is turned on, and generates an appearance probability table for items of game software to be activated for the first time. After the table creation means 14b and the game start, the function of the item appearance execution means 14c for executing the item appearance with the probability based on the probability table creation means 14b is provided.
[0011]
Although the values in the probability table are created at random, the pseudo-random numbers generated by the CPU after the power is turned on have regularity. Therefore, it is necessary to prevent the randomness from being the same by some means. The irregular signal generating means 14a is for that purpose. In this embodiment, the time until the start button of the operation unit 17 is pressed is checked, and the random number table is updated using the checked time, and the item appears. Creates a probability table.
The irregular signal generating means 14a checks the length of other buttons being pressed, and uses the pressed time, the name input by the player, and the time of a clock built in the game machine. Can be used.
[0012]
FIG. 4 is a flowchart showing the flow of creating an item probability table when the power is turned on for the first time after obtaining new game software.
When the power switch 16 is turned on (step (hereinafter referred to as “S”) 401), the hardware portion in the game machine is initialized (S402).
Next, the random number output by the CPU is updated (S403). Then, the random number is updated using the timing until the start button of the game is pushed by the irregular signal generating means 14a (S404). This is to prevent the initial value of the random number from being the same as that of other game machines.
When the start button is pressed, the update of the random number is stopped, and then it is determined whether or not the item probability table already exists in the backup RAM 19 (S405). This is to determine whether or not it is the first play after obtaining the game software.
[0013]
If the item probability table already exists, the game is started (S407). On the other hand, if the item probability table does not exist, the probability table creating means 14b is activated to proceed to the creation of the item probability table (S406), and the game is started after the item probability table is created (S407).
FIG. 6 is an example of a probability table and a flowchart for explaining the procedure for creating the item probability table.
6A, a basic probability table prepared in advance (stored in the ROM 18 together with the item data 18b) is read from the ROM 18 and loaded into the RAM 20 (S601). FIG. 6B shows an example of the basic probability table. Percentage is the probability that an item will appear, adding up all to 100%.
[0014]
Next, the order of the basic probability table is changed according to random numbers (S602). FIG. 6C shows an example in which the basic probability table is replaced.
Further, the items A to G are associated with the replaced probability table, and the table creation ends (S603). FIG. 6D is an example of a completed item probability table. Items B and E are 0%, and there is no possibility of appearing at all. The completed item probability table is stored in the backup RAM 19.
[0015]
FIG. 7 is a flowchart for explaining an item selection procedure during the game.
This item selection is realized by the function of the item appearance executing means 14c of the CPU 14.
The CPU 14 determines whether or not it is time to make an item appear during the game (S701). If it is determined that it is time to appear, a random number (0 to 99) is generated, the value of the generated random number is stored in the memory R in the CPU 14 (S702), and the item selection pointer is placed at the head of the item probability table. (S703). Then, the probability value of the selected item is subtracted from the value of the memory R (S704), and if the subtraction result R1 is smaller than 0, the selected item appears (S707). For example, if the random number indicates a value of 20 and the selected item is D, the probability is 30%, so 20-30 = −10, and the item D appears.
[0016]
On the other hand, if the subtraction result R1 is greater than 0, the item selection pointer is advanced to the next item (S706). Then, S704 and S705 are executed again, and this is repeated until R1 becomes smaller than 0. An item with R1 smaller than 0 as a result of subtraction by this operation is selected and made to appear.
[0017]
In the above embodiment, an example is shown in which the generated item probability table is stored in the backup RAM of the game cassette. However, the item probability is not stored in a game machine of a type that can be backed up, but in another memory installed in the game machine body. Of course, the scope of the present invention also extends to storing tables.
[0018]
【The invention's effect】
As described above, the present invention generates an irregular signal based on a predetermined operation of the player, and when the game application software installed in the game machine body is started for the first time, the irregular signal is used to generate a plurality of signals. A probability table for causing an item to appear is created, and after the game starts, an item is made to appear based on this probability table and the game proceeds.
Therefore, it is not necessary to prepare a plurality of programs with different item appearance rules from the beginning, and a game machine having functions equivalent to a game machine having a plurality of programs with different data can be realized with one program.
In addition, since the game program itself is the same and the items appearing differently can be obtained or cannot be obtained by humans, a plurality of programs with different data contents generated as described above can be used in a game machine that can be backed up. Becomes an object of exchange with others, and it is possible to further increase the fun of the game.
