Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microcomputer for controlling a gaming machine typified by a pachinko gaming machine, an arrange ball, a rotary type gaming machine, a jean ball gaming machine and the like.

[Background of the Invention] In recent years, in gaming machines, for example, pachinko gaming machines and the like, the enjoyment of the game has been enhanced by a variable display game with a special symbol display device arranged substantially in the center of the game area.

In this variable display game, for example, when a predetermined game condition is satisfied, the symbols displayed in the special symbol display device start variably displayed, and the variability is stopped after a lapse of a predetermined time. It is common to make a big hit when the symbols are arranged in a specific pattern, and in such a variable display game, the determination of the big hit, the determination of the symbol at the time of stop, etc., include a stochastic element, It's a coincidence that makes the game interesting. For this reason, a random number with uniformity and irregularity is used for the determination of the big hit, the determination of the stop symbol, etc., and such a random number is generated by the game control circuit.

In the case of "Y"), the data loader interface circuit 40 is notified that the master program data is ready to be read, the game information read processing program stored in the data loader interface circuit 40 is activated, and the ROM writer 50's The reading process of the master program stored in advance in the master ROM 60 is performed (step S23).

Next, it is confirmed whether or not the transmitted program data is the final information (step S24), and if it is the final information ("Y"), the read program data and the program data stored in the internal ROM 21 are checked. A normal state notifying process for notifying the data loader interface circuit 40 that the result of comparison with is normal is performed (at this time, an end signal indicating normal end is also sent) (step S25), and the process "A" Then, the processing shifts to the processing shown in FIG.

When the transmitted program data is not the final information ("N"), the user program reading process for reading the game program stored in the built-in ROM 21 is performed (step S26), and the master program read previously is read. The consistency with the data is determined (step S27). If there is consistency (“Y”),
To determine the next block, the process returns to step S23 to read the master program data, and the processes of steps S23 to S27 are repeatedly executed until the final information is sent. If there is no consistency (“N”), the data loader interface circuit 40 is notified that the comparison determination result is abnormal, and the LED 44, the buzzer 45, and the like in the data loader interface circuit 40 are notified of the abnormal condition. The abnormal state notification process is performed, the execution of the game program is prohibited, and the progress of the game is stopped (step S28).

Therefore, in the gaming machine microcomputer 100, the built-in ROM 21 for storing the user-side game program and the built-in ROM 1 for storing various programs for checking the user-side game program.
Since 02 and 02 are separately provided, it is possible to separately store programs having different purposes in each storage unit, and to separately store programs to be concealed that should not be disclosed to a third party.

Further, the game machine microcomputer 10
At 0, since the built-in ROM 102 has a built-in program for comparing and judging the consistency between the regular game program (master program) read from the outside and the game program stored in the built-in ROM 21, the written game program is It can be easily determined whether it is legitimate.

Next, in the case where the program stored in the data loader interface circuit 40 sends and receives data between the gaming machine microcomputer 100 and the ROM writer 50 and notifies the program data consistency determination result. The flowchart will be described with reference to FIG.

First, in FIG. 12, initialization processing (initial processing) of built-in devices and registers of the data loader interface circuit 40 is performed (step S3).
1), it is monitored whether or not the activation switch 41 is turned on (step S32). If the activation switch 41 is turned on (“Y”), a activation signal is sent to the gaming machine microcomputer 100 (step S33), and if the reading of the gaming machine microcomputer 100 is good (step S34), ROM is set. A process is performed to confirm whether or not the writer 50 is ready (step S35). If you confirm that the ROM writer 50 is well prepared, the master RO
The master program is read from M60 (step S36), and the read master program is sent to the gaming machine microcomputer 100 (step S37).

Then, the gaming machine microcomputer 1
When the determination result of the comparison between the game program of the internal ROM 21 and the master program is input to the data loader interface circuit 40 from 00, it is determined whether the determination result is an abnormal signal (step S38). If the signal is an abnormal signal ("Y"), an abnormal state notification process for notifying an abnormal state by the LED 44, the buzzer 45, etc. is performed (step S39), and this process is stopped.

If it is not an abnormal signal ("N"), it is judged whether or not an end signal is received from the gaming machine microcomputer 100 (step S40), that is, the consistency with the master program data is confirmed. In this case, if the end signal is not received (“N”), the process returns to step S34 to confirm the read preparation of the gaming machine microcomputer 100, and until the end signal is sent, step S34. The process of S40 is repeatedly executed. When the end signal is received ("Y"), LED4
4, a normal state notification process for notifying the end of the consistency check by the buzzer 45 or the like is performed (step S4
1), this process is stopped.

Therefore, in the data loader interface circuit 40 as the inspection device for the gaming machine microcomputer of the present invention, the master program is read from the ROM writer 50 and the gaming machine microcomputer 10 is read.
By sequentially sending the data to 0, the consistency between the game program stored in the built-in ROM 21 of the game machine microcomputer 100 by the built-in ROM 102 of the game machine microcomputer 100 and the master program written in the ROM writer 50 is compared. LED4 is the result of the judgment
4 and the sound of the buzzer 45, and the like, so that the determination result of the program consistency can be easily confirmed.
