PROBLEM TO BE SOLVED: To provide a game machine having a hardware configuration capable of properly controlling start timing of a general-purpose processor and a dedicated processor.SOLUTION: A performance control part 22 for controlling performance operation including a sound performance comprises: a first reset part RT1 for generating a first reset signal SYS based on the fact that a DC voltage received from a power supply board 20 has increased from zero to a specified level; a second reset part RT2 for generating a second reset signal RSET when a predetermined period of time has passed since the first reset signal SYS; a one-chip microcomputer 40 for controlling performance control operation; a sound synthesis circuit 42 for reproducing a sound signal necessary for the sound performance; and a sound memory 43 for storing basic data of the sound signal. Reset operation of the one-chip microcomputer 40 and the sound synthesis circuit 42 is executed based on the second reset signal.SELECTED DRAWING: Figure 6 |
