Quoted from nerdygrrl:My first instinct is to swap out the trough boards with another game, but I wasn't sure if I was missing anything else.
Trough opto board problems at common with the OEM "widebody" boards. These are the board set used in:
- Indiana Jones
- Judge Dredd
- Star Trek the Next Generation
- Popeye Saves the World
- Demolition Man
Medieval Madness does NOT use this board set.
You can swap with boards from a compatible machine but it may not fix the problem. Go to the switch edge test and drop balls into the trough and see what switches register.
