I design and build arcade superguns and adaptors for arcade enthusiasts. The superguns allow the gamer to connect a JAMMA arcade PCB to a TV set. This saves the gamer money because they dont need to buy a JAMMA cabinet to play the game. A lot of arcade PCBs have a non standard edge connector. An adaptors is needed to convert the edge connector to a JAMMA format. This then allows the gamer to play the arcade PCB on a JAMMA cabinet
