<P>PROBLEM TO BE SOLVED: To surely prevent erasure of game data of, at least, one generation before. <P>SOLUTION: This game machine 10 includes a CPU 40 and, when a game cartridge 32 is installed in the game machine 10, the CPU 40 is electrically connected to a ROM 56 and a flash memory 58 having two backup regions in the game cartridge 32. Game data formed according to the progressing state of the game are stored (updated) in a work memory 44, for example, latest game data are written in the backup region according to the command of a user. When writing the latest game data, the CPU 40 selects the backup region storing game data whose written time is older, as the backup region of the writing object. Then, if the writing in the selected backup region is impossible, overwriting on the game data written right before is prohibited and the game data of one generation before are left. <P>COPYRIGHT: (C)2004,JPO |
