1 Introduction
Most modern game systems have a free play option available within the game's settings. However, older games do not always have an obvious way to enable free play.
There are a few different options depending on the game system:
- Set the first replay score value to 10,000.
- Add a stacked switch added to the start/credit button switch.
- Add a switch to the coin reject button.
- System-specific wiring modifications.
- Replace the game ROM with an EPROM with a modified version of the game code.
The goal is avoid having to install an extra on the outside of the cabinet or coin door and to avoid having to open the coin door.
