Not sure if I've got this in the right area, but my question is concerning building a Jamma Adapter for a B&W game. The pinout calls for Pin20 to be Video and Pin 21 to be Video Return.
On the Jamma side I just ran a wire to Composite Green for Video (I'm just using this adapter to hook the board up to a PAT for testing) with the Jamma harness. But I don't know what Video Return is. Is that the Video Sync? Video Ground? I'm thinking it's Sync, but am not sure.
