PROBLEM TO BE SOLVED: To preserve necessary data and resume a game from a state when power is interrupted at power restoration time at the time when unforeseen power interruption such as blackout or the like occurs and reliably save necessary data. SOLUTION: When a game machine is structured so as to judge whether final storage contents stored in a backup RAM area are normal or not on the basis of a checksum stored in the backup RAM area when power supply to a game machine is initiated and if they are normal, execute control so as to restore the controlling state to a state before power supply is suspended on the basis of the final storage contents, as the checksum is stored in a halfway address of the backup RAM area, there is no need for comparing the result of operation with the content of a checksum buffer and as only comparison with 00 (H) is required, parity check is simplified. |
