Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 2001-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a control for an initial operation with agility and stability. SOLUTION: At power supply start processing, in the case of initialization processing, a CPU(central processing unit) sends initialization commands for initializing each subboard according to a command sending table at the initialization. In the case of state restoration processing, the CPU sends initial commands for restoring a controlled state of each subboard according to data stored in a backup RAM(random access memory) area and a command sending table at a backup. A command sending table at a special pattern backup is selected on the basis of a special pattern process flag value, or the like stored, in the RAM, and an initial command is sent according to the selected table. The process provides the control for the initial operation with agility and stability.
