PROBLEM TO BE SOLVED: To provide a game machine having a reduced amount of code of a game control program.SOLUTION: A game machine including a game control device includes: a game control program memory unit; a calculation processing unit for executing calculation processing; a register for storing data upon performing the calculation processing; and an update information memory unit for storing information updated by the calculation processing unit. A stack area is set in the update information memory unit. The register includes a flag register for storing a calculation result of the calculation processing unit. A game control program includes a calling routine, a first called routine called from the calling routine, and a second called routine called by a predetermined interrupt signal. When the first called routine is called, the calculation processing unit stores a return address in the stack area, and starts the processing without storing the flag register, and when the second called routine is called, the calculation processing unit stores the return address and the flag register in the stack area, and starts the processing. |
