Oh, yeah. Now I know what to call that. That's how Pandora's Boxes are wired up, right? I think my Red Box is too.Chinese "JAMMA". Basically JAMMA with extra 4/5/6 buttons available from pins 25/26/27 (P1) and c/d/e (P2) on the JAMMA edge connector.Usually pins 25/26/c/d are unused but 27/f are ground in JAMMA standard.What is CHAMMA?
