To provide a possible graphics game system.

A fourth aspect of the present invention is to provide a real-time three-dimensional graphics game system that allows a new game to proceed by simply replacing the game ROM without replacing the board.

Hereinafter, the operation of the present invention real-time three-dimensional graphics game device will be described with reference to FIG.

When the power is applied, the system management unit 1a of the central processing unit 1 enters the management of the game system, reads all the input commands of the user input through the user interface unit 5, and switches the screen corresponding to the command. The entire memory system is managed by storing and outputting information necessary for sound processing, etc. using the system memory 2, and at this time, system initialization is performed from the ROM BIOS 3 and the game program of the game ROM 4 is executed.
