I recently put the swemmer MPU into my system 80 Counterforce and it works great! My game already had the ni-wumph driver board in it, too...which is a plus.
Quick question- I still need to do the ground mods.
Can/should the ground mods be done with a game that has these two boards already running? And if so, do the ground mods need to go somewhere else on these boards?
Thoughts?
