If it was me, I'd do like some of the multicades have. A stick in the middle, and 2 buttons on each side. That way, you can do games either lefty or righty. I've thought about building a 2nd MAME cab (maybe a cocktail), and make it a vertical (The one I have now is horizontal). Also have 2 joysticks, 1 4-way, for all the Pac-Man games, and an 8 way for others.
