PROBLEM TO BE SOLVED: To provide a game machine for improving development efficiency while inhibiting illegal action of changing a programming memory. SOLUTION: An MPU is attached directly to a main control board C, making it impractical to perform illegal action of changing the MPU with an incorrect MPU and inhibiting the illegal action. An arrangement space 45 is provided around an area where the MPU is attached directly thereto and so an IC socket 40 can be mounted on the space 45 at a development stage and the MPU be detachably mounted on the main control board C via the IC socket 40. Therefore, the change of the MPU is facilitated at the development stage and the development efficiency is improved.
