I was wondering if anyone else has done this: Taken the backs of two idectical controllers (but of different colors) and switching them. I have done this with N64 and gamecube controllers, so I have purple and orange Gamecube controllers and red and green N64 controllers. This could also be done with colored systems, like the N64, Game Boy, Game Gear (they made a blue one I think), or others. It is an easy way to customize your stuff and identify it if it gets mixed with other's stuff.
