I just got one of these so I wanted to take some decent pics and put it out there.
The PCB is just a straight adapter from the connector to JAMMA with a big ceramic resistor on the +5 rail. It has mono amplified audio, video, and player 3 and 4 controls. There's nothing to do or configure in terms of bios settings, dip switches, or game requirements. It is just a dumb cable and PCB. I've only done a really quick test, so I'm not sure if there's any opportunity to remap 2 player games to be split across two cabinets. Audio does not get lower nor does video get dimmer when using two cabinets so it would appear the signals are split/amped appropriately and not just wyed together.
