Adam and Rich also have schematics for some dual board games like Ramtek Baseball and Allied Leisure Street Burners.
Next round of schematics going to them might be Ramtek Trivia and PSE Knights in Armor since those are single board games. Roms are still needed for Knights in Armor so it might only be partially playable or more likely maybe not....depending how much data each of the two roms of Knights in Armor controls.
