Game memory
First Claim
1. Game equipment having a read-only memory for storing a game program, a microprocessor for controlling the game program stored in the read-only memory, random-access memories having registers for storing informations of a game and, a screen RAM, said game equipment being adapted to be operated by an operation keyboard and the microprocessor associated therewith in accordance with the game program stored in the read-only memory, game operated by the keyboard being adapted to be displayed on a picture display score, said game equipment comprising:
- a backup battery,a backup memory actuated by the backup battery,recognition means for recognizing information of registers in the random-access memories used to display on the picture display screen, said information being changed continuously in accordance with process of the game,transfer means for transferring the information of the registers recognized by the recognition means to the backup memory, anddrive means for automatically actuating the transfer means repeatedly at a substantially predetermined interval without a specific command, said backup memory, when new information recognized by the recognition means is transferred to the backup memory by the transfer means, storing the new information by erasing information stored already therein, said game equipment, when started, reading the information in the backup memory so that the game can be started based on the information stored in the backup memory.

Abstract
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.
