<P>PROBLEM TO BE SOLVED: To provide a game machine for performing authentication between control devices and determining correctness, the game machine being restored to a state before power failure even if the power interruption occurs during the authentication. <P>SOLUTION: A game play microcomputer includes an encrypted communication unit, a proper connection determining unit, a determination result storing unit, and a shooting control device. The microcomputer is configured to perform: power interruption processing for storing a power interruption flag in a memory and waiting until power interruption, with a power interruption detecting signal as a performance starting condition; and power-on processing for holding game information when the power interruption flag has a predetermined value, and initializing the memory when the power interruption flag has a value other than the predetermined value. Power-on processing is performed; direction for starting mutual authentication is set on the proper connection determining unit; after starting performance of the mutual authentication, the determination result storing unit is made to repeat determination until a predetermined determination result is stored; and determination as to whether the power interruption detecting signal as the condition for starting the power interruption processing is detected or not is repeatedly performed. Only when the mutual authentication is completed, a shooting permission signal is output. <P>COPYRIGHT: (C)2013,JPO&INPIT |
