Game equipment having a read-only memory storing a game program, as well as a microprocessor, random-access memories (RAMs), an operation keyboard and a picture display screen, wherein the microprocessor controls registers such as those constituting a screen RAM and a data RAM in accordance with the program stored in the read-only memory. The equipment includes a backup battery and a backup memory to which the supply of power is ensured by the backup battery, and also includes a recognition section for recognizing information on particular registers used to display a picture on the picture display screen, a transfer section for transferring the information on the registers recognized by the recognition section to a storage provided in the backup memory, and a drive section for causing the transfer means to automatically repeat transfer operations at a required timing. The storage is adapted, when new information on particular registers has been transferred by the transfer means, to erase the previously stored information and store the new information.
