Hi
On my arcade I use hyperspin for my frontend in the cabinet is just an upgraded PC with a touchscreen monitor and everything run through an ipac which is a must I think makes everything so much easier got loads of emu on it also got n64 but hit a problem with configuring buttons on that started to mess up everything so left it alone so will be interested if you get this working also with the GameCube,got a friend who is clued up better than me helped with the hardrive but nothing been changed on it for the last four years if you want a copy of the hardrive that's not a problem,the aimtrak light gun was a bit of pest to set up back then might be easier now can't beat playing carnevil and area51.
Cheers brian.
