<P>PROBLEM TO BE SOLVED: To provide a game machine that improves security strength while suppressing an increase in the processing load of a peripheral part. <P>SOLUTION: A main control part has: a first identification means that identifies to which group A or B a control command output this time belongs; a first generating means that generates a single test value by using a control command, output last time, of the group to which the control command output this time belongs and generates a cumulative test value by using all control commands, output in the past, of the same group; and a first determining means that determines the type of error test value, to be output this time by the first generating means, on the basis of the identification result of the control command output this time and the control command. The first generating means outputs an error test value, being the type based on the determination result, to a post-stage control part via a peripheral part. The post-stage control part generates an error test value for an error test and executes the error test by using the generated error test value and the output error test value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
