My TNG is having an issue where the right orbit rollover (sw 58) also triggers the left gun launch opto (sw 38) and the borg entry opto (sw 48). I've tried checking their shared ground on both the opto board and cpu (white-gray wires) but they seem ok.
It causes the game to credit you with picard maneuvers and delta ramp shots that it shouldn't due to the borg entry opto being tied, but the left gun seems to function normally.
Any idea where I can start? thanks
Edit: after a little more looking and taking a slo-mo video of the dmd, I can see that the gun opto circuit opens and the Borg opto flickers pretty rapidly between open and closed if I hold down the rollover.
