Filed: 2021-09-17
Abstract: To provide a game machine capable of suitably performing processing when operating power starts to be supplied.SOLUTION: When operating power starts to be supplied, a main-side CPU 63 determines whether a power failure flag, a checksum, and a setting value are abnormal. When either information abnormality occurs, a regulation state in which a start of processing for proceeding with a game is regulated results. In this case, power failure monitoring and update of various counters are performed regardless of the regulation state. When the regulation state results, an abnormality signal corresponding to it is outputted externally. The main-side CPU 63 basically prohibits execution of timer interruption processing in processing when operating power starts to be supplied, but permits execution of timer interruption processing in execution of setting value update processing or setting confirmation processing.SELECTED DRAWING: Figure 6
