this is exactly what I"m going to do for my PS2 cab, but I'm going to have the Ms. Pac-Man 4-way attached to both P1 and P2 (cuz namco Museum is funky, if you have 2 controllers plugged in, it forces you to use the second player, but if only one controller plugged in, you gotta share like the original cabinets. I may rethink this though and just hook it up to p1)
