PROBLEM TO BE SOLVED: To provide a game machine capable of reducing the code quantity of a game control program.SOLUTION: A game machine comprises: game control program storage means; arithmetic processing means which performs arithmetic processing; a register in which data is stored when the arithmetic processing is performed; and update information storage means in which information to be updated by the arithmetic processing means is stored. A stack area is set in the update information storage means. A flag register to store an arithmetic result by the arithmetic processing means is included in the register. A call source routine, a first call destination routine called from the call source routine, and a second call destination routine called by a predetermined interruption signal are included in a game control program. The arithmetic processing means, when the first call destination routine is called, stores a return address in the stack area and starts processing without storing the flag register, and, when the second call destination routine is called, stores the return address and flag register in the stack area to start processing.SELECTED DRAWING: Figure 48 |
