PROBLEM TO BE SOLVED: To realize a game machine which can increase the processing speed of CPU by reducing load on a CPU for executing main control. SOLUTION: When main CPU 112 detects a special symbol starting memory number equal to or more than 1 (S62: YES), a variable pattern of the special symbol is determined (S64) and an image control command corresponding to the variable pattern is outputted (S68). When an image control command is inputted to a sub-CPU 32e (S322), the image control command is checked (S324) and contents of the image control command are analyzed (S326). Then, sub-CPU 32e sets the allowance of an interrupt (S328) and sends a display signal corresponding to the analysis result in S326 to a VDP(video display process) (S330). Thus, load on the main CPU 112 can be reduced because the main CPU 112 only outputs the image control command according to need.
