Hello,
Long time reader, first time post. I'm setting up a Donkey Kong 4-Stack (TKG3) to play on a Jamma supergun setup. I'm using Mike's Arcade edge connector and NES to Jamma adapter, and the "Retro Arcade" power supply. Everything seems to be working fine, except the buttons do not map correctly. Pressing the 'service' button on the supergun gives me coin, but the button I normally use for coin doesn't. 1P/2P start also doesn't work, but if I tinker with the pins on P5, I can get a game to start. During gameplay, the D-Pad works correctly, but none of the buttons jump. I'm trying to figure out if the problem is the stack, the edge connector, the adapter, or possibly even the supergun. I have a dozen other PCBs that work fine with the supergun, so I'm not sure why this would be different.
EDIT: Apparently it was a broken voltage isolator.
