bought a mame cade from a board member today. when i got it back to my house, the controls dont respond. it is a jpac with jamma wiring ( i think). i get no response when I use any of the controls or the buttons.
if i plug the jpac (via ps/2) cable into another pc I have, all the buttons seem to work except the player 1 joystick (up,down and left.. right works)
no idea how to proceed
