The oldest game on the Replay SpecialEffect stand is planned to be the legendary Taito Space Invaders. This version will be made one-switch accessible, including putting in the money, selecting a one-player game and playing.
The game will only work in this way by using an old version of MAME (v0.92), the 4Noah utility and MAME cheats (v0.81). You need to own the Space Invaders PCB too to play this legally. I did contemplate bringing my cocktail Space Invaders, but I don't think my Car's suspension could cope. Here's an idea of how it will play.
