I thought the playchoice arcade is the nintendo versions of the games.
The red tent uses the nintendo unisystem board which are the arcade version games. The games are burned on eprom chips. You need the correct color palette security ppu chip, the rp2ao3 cpu ic and the dummy ic rp2a04 for super mario bros if you dont have a jumper (sewrch forums) or another cpu on the other cpu slot side of the board.
