If any of you out there are wondering how to make a jamma harness work with a neo geo mvs board or are experiencing sound trouble when you hook an mvs pcb board to a jamma harness than this video should help you to get to gaming on your MVS with the sound you want. Really simple job, only requires the moving of the wire on point `M` on your JAMMA harness to any `GND` or Ground point on your harness and BINGO! you are all set. Also if you have a 2, 4, or 6 slot mvs mother board, connect pins `d` and `26` to a standard button in order to have the select feature on your multi slot mvs board.
