<P>PROBLEM TO BE SOLVED: To provide a game machine for improving security strength. <P>SOLUTION: A main control part includes: a first generation means for generating an error inspection value that is added to a control command output from a command output means and inspects validity of the control command by using a control command output in the past, using a plurality of generation systems, and outputting the error inspection value generated by one of the generation systems by using the control command; a first identification means of identifying a group of two or more predetermined groups to which the output control command belongs; and a first decision means for deciding the generation system of the error inspection value, based on the output control command. The first generation means uses a previous control command among control commands belonging to the same group as that of current control commands output by a command output means to generate the error inspection value with a generation system decided by the first decision means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
