generating latest game data corresponding to latest conditions in a game being played;
designating one of said game data backup storage areas that contains an oldest written game data relative to game data written in other backup storage areas as a write-objective target for storing said latest game data and, when a write attempt to a first write-objective target is unsuccessful after a predetermined number of attempts, designating another write-objective target of next oldest written data; and precluding a writing of said latest game data into said another write-objective target and prohibiting further attempts to write to said backup storage areas when an attempt in writing to said first write-objective target backup storage area is unsuccessful after a predetermined number of repeated unsuccessful attempts and said another write-objective target contains the only remaining instance of saved older game data; and
causing said game machine to display an error message indicative of an unsuccessful saving of said latest game data and/or a broken backup storage memory condition, wherein a failure of a memory element in said electrically rewritable non-volatile memory does not result in an attempt to store game data in a last remaining backup area containing older game data.
