Reddit reviews Wii Component Video Cable

Probably the official Nintendo one

I use component cables to put my Wii to an HDTV to play GC games. I find it's better than composite cables, and I've read that HD converters have necessary lag and some image infidelities otherwise anyways.

This is the cable, but this listing is just to show you what it looks like - don't spend anything near that... search amazon for a generic 'wii component cable' and you should be able to find one for like $10-$20

They'll look the same as they do running on a Wii with component cables. Which is to say waaaay better. Metroid Prime might bring tears to your eyes.

So if you're looking to get the best out of your Gamecube games and don't have millidooms' incredible luck, and you have a Wii, the official Wii component cables are $40 from Amazon and will get you the same performance.

The tv has the standard component hookup, this is the cable I'm using and I've re-seated it a few times. http://www.amazon.com/Wii-Component-Video-Cable-Pc/dp/B000JJRV90

Are you sure? I'm looking at it on amazon and the wii end looks a lot like the port on the gamecube, but it also says this under product features,

"This component video cable is for the Wii and will not work with any other system. In addition, the Nintendo GameCube Component Video Cable will not work with the Wii."
