<P>PROBLEM TO BE SOLVED: To provide a game machine achieving desired security operations without making inherent performance control operations trouble. <P>SOLUTION: Main control part executing game control operations includes a backup means for maintaining the contents of memories of a RAM (Random Access Memory) even after power source cutoff, a setting means ST2 able to arbitrarily set a RAM memory region to which access is forbidden, a detection means 51 for detecting fraudulent access to the RAM to which access is forbidden, the first reset means G6 for making a CPU (Central Processing Unit) forced reset from a result detected by the means 51, a reset control means G5 for permitting/inhibiting the forced-reset operation through the reset means G6 and a deletion means ST10, preceding a start of a normal game control operation, for deleting the contents of the memory of the RAM from an artificial indication. While the deletion means ST10 works under the forced-reset operation being forbidden, after that, the normal game control operation starts under the forced-reset operation being permitted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
