Quoted from brg126:They all have the red / green wire in common. I imagine it is somewhere along there. Seems odd that 2 switches that use the wire would work though.. Looks like I get to learn about crazy capcom wiring!
Just tracked down wiring issues on mystery castle. Check the diodes as well. I tested my game with two different working boards and was getting different results with the same boards. One board had only 1 switch in the column working. The other had multiple switches that worked. Fixing the diode leads that snapped off fixed the issues with both boards.
