PROBLEM TO BE SOLVED: To surely prevent illegal act such as sharpshooting based on analysing result of a program that controls operation of a game machine.SOLUTION: By allowing a bit value of bit number (4-3) of security time set KSES to be a value other than "00", a variable set time that changes within a predetermined time range each time an initial set process is executed based on system resetting or turning on of power supply, is set as time component that is contained in the security time. Further, by allowing a bit value of bit number (2-0) of the security time set KSES to be a value other than "000", any one of a plurality of extension times that can be selected in advance in addition to a fixed time is set as a time component contained in the security time. The variable set time is decided at random by using, for example, a count value of a free run counter built in a micro computer for game control. |
