Yeah... i'm with Paul on that one. Just make a couple of different control panels. They are easy to unplug and pop back in on demand. I remember seeing a few that had even built insane ROTATING panes... triangular shapped, with three different control setups on each face of the triangle. THAT would be trick.

You could easily handle all those controls with a couple of Opti-PACs and IPacs from Ultimarc. Man, if i only had a garage... the modding to my MAME cabinet would be endless.
