<p><P>PROBLEM TO BE SOLVED: To efficiently perform a process for recovering a game state, and at the same time, prevent the control from being obstructed even when an instant breakage or the like of a power source is generated. <P>SOLUTION: In the game state-recovering process, a CPU performs the returning process of a stack pointer, and if the state is not a put-out prohibited state, sets a command-transmitting table regarding a put-out available state- designating command, and the command-setting process is called. Also, a command-transmitting table regarding a command for recovering other control states is set, and the command-setting process is called. Then, a process for setting retracting values of various kinds of registers or the like is performed for various kinds of registers, and then, a RET command is performed. Also, in a standing-by state after a masking unavailable interrupting process which is performed due to an instant breakage or the like of the power source, the CPU starts a main process based on a returning signal, and the control is continued by the recovering process from the control state at the time when a power source breakage signal is generated. <P>COPYRIGHT: (C)2003,JPO</p> |
