AI Technical Summary
Technical Problem
Existing gaming machines face pressure on the program area of the main RAM due to the need to revert comprehensive state information after each game, which affects development efficiency and maintainability.
Method used
The gaming machine employs a dual-bank memory structure with separate storage areas for game-related and non-game-related programs, using specific call and return instructions to switch between banks, and enables interrupt control states to optimize memory usage.
Benefits of technology
This approach reduces memory pressure by clearly switching between processing banks, improving development efficiency and maintainability by streamlining program structure and reducing the need for backup recovery processes.

Abstract
This invention provides a gaming machine that partially unifies the backup and recovery process, which restores predetermined information to its pre-game state, with the backup process, which backs up the predetermined information, thereby reducing the pressure on the program area capacity of the main ROM. [Solution] In the game start state control process of the main process, a backup of various information is acquired, and further, in the game end state control process of the main process, a process is provided to restore the backed-up various information according to predetermined conditions. In this process, when backing up and when restoring the various information, the values of the registers that store the addresses of the respective data storage areas are swapped, thereby making some of the programs common.
