Like the title says, have you seen this daughter board? And what's it for? I bought this cps2 board off YAJ and it doesn't work. Opened it up and it has no battery. Is this little board some kind of battery bypass? I see a bunch of little solder pads like the undamned infinikey...board boots to black ️ screen. Probably suicided. Any guesses?
