Quoted from slochar:Even if this fixes your issue I'm going to move forward with the rom deep-dive and make a run at the core issues with the switch handling. I know Oliver did this years ago, but that fix needs some kind of rom expander to work. I'll see if I can shoehorn it into the normal rom footprint and take a different pass at it.
Really nice! I had the oliver rom in my game and it’s a big improvement, like it. I will really appraciated if you redo it Scott. Thank you
Quoted from Barakawins1:Update: I've managed to isolate this issue to a mis-wire by the prior owner at the left slingshot. If anyone has wiring photos for the two left slingshot switches
under the playfield that would be fantastic. I need to see which lugs the .05uf capacitor attaches to, Which lugs the diode attaches to and there is a white/brown wire and white/yellow wire which also attaches to the lugs. Thanks in advance. This should fix it all.
This is the pics i found in my playfeild swap file
