I have a third-party s-video cable for my Gamecube, and inspecting the data out port on the Wii, they're similar but not the same. I once ruined a pair of in-computer speakers by mistaking a headphone jack for an RCA jack, so I'm not really interested in trying to connect up the cable to the Wii if they're not compatible. But it looks like they would mate. So what's the word: Can you use Gamecube cables on the Wii?
