I have recently been thinking about making an N64/Gamecube hybrid. I wanted to have a 3-way switch such that when it was in the middle, both systems would be turned off. When you slide it to one side, the Gamecube turns on. Slide it the other way and the N64 turns on. How would I go about doing this? I also wanted to know if I could use a Gamecube controller to control both systems. If this was possible, could I use the power switch to switch between using the controller as a GC controller and an N64 controller?
EDIT: Actually, I think I'll probably not use the GC controller for both consoles. I know, I'm indecisive.
EDIT2: Made some progress. I haven't actually taken anything apart yet, but I figured out how to plug both systems into one outlet. I have a cable that has two female power outlets and one male. If I plug this into another cable that has one female power outlet and one male computer cable outlet (like this one), I can put the male computer cable port on the outside of the system and use a regular computer cable to power the system.
