PROBLEM TO BE SOLVED: To prevent the illegal modification of the contents of game control information and easily inspect the information by mounting a game control means, an inspection information memory means and a game control information memory means respectively on a game control substrate. SOLUTION: A basic circuit 66 for controlling each equipment of a pachinko (Japanese pinball game) machine according to a control program is provided with a game control CPU 96, RAM 97, ROM 98 and a clock generation circuit 99. Also, the circuit 66 is provided with CPU 100 and RAM 102 for a security check. Furthermore, a program write circuit 103 and inspection ROM 117 are respectively housed in separate semiconductor packages and mounted on a game control substrate 113. In particular, the ROM 117 is mounted so as to be detachable from the substrate 113 for the convenience of program inspection. As a result, the contents of the game control information is protected against an illegal modification and can be easily inspected. |
