PROBLEM TO BE SOLVED: To provide a game machine capable of effectively utilizing information on an error generated by a fraudulent act.SOLUTION: A game machine has a sub-control circuit 70. The sub-control circuit 70 comprises: a sub CPU 71 which receives a command encrypted in a main control circuit; command decryption means 71a which decrypts the received command; error information registration means 71e which registers error information on condition that an error factor is included in at least decrypted command; and error information history display means 71g and a liquid crystal display device 5 which display the error information. The main control circuit encrypts the command by replacing data of a plurality of bytes which configures the command in a predetermined encryption procedure, and the command decryption means 71a has a composition in which the encrypted command is decrypted by replacement in a predetermined decryption procedure.SELECTED DRAWING: Figure 7 |
