Here is my dilemma. I have a perfectly working buck hunter shooters challenge pcb working in one of my jamma arcade machines. I then moved it to a different arcade jamma machine with a better quality screen. In this new machine the game and sound works as normal however I can't get any buttons to work, Start, test, volume up down as these are the only buttons on this machine. I tested a golden tee fore pcb on this cabinet and the buttons work fine for that game but not for buck hunter. I put buck hunter back in the original cab and the buttons work fine there. The jamma harness configuration in both cabs are fairly similar. The only difference I can see between the 2 cabs are the working cab has a switching power supply connected to the jamma harness with a -5volts also present. Where the non working cab has no switching power supply and no -5volt cable. The buck hunter pcb runs and gets its power from a stand alone atx power supply and is a green IT pcb board.
Any help to get it working in the new cab would be greatly appreciated. Thx in advance Joe
