I have an Xbox 360 and I like playing games on it but I'm thinking sometime I want a Gamecube so I can play games like Super Smash Bros and LoZ etc. but if I have two consoles wouldn't I need to unplug the yellow white red cords and plug in the ones for the gamecube and vice versa. Is there some kind of thing that makes it so I can plug in all the cables and whichever console is turned on will display and sound on the TV without having to unplug/replug?
