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. That being the case, 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.
There are a few different options depending on the game system:
- Set the first replay score value to 10,000 (or whatever the lowest possible score is).
- Add a stacked switch to the start/credit button switch.
- Add a switch to the coin reject button.
- System-specific wiring/jumper modifications.
- Replace the game ROM with an EPROM with a modified version of the game code (typically known as a free play ROM or Home ROM). Some of these ROMs have additional fixes/features beyond just a free play option. Most MPUs will need to have some jumpers changed in order to accommodate an EPROM.
