I don't remember specifically, but it might be possible to install a homebrew channel by using a trucha-signed disc. To my recollection, the trucha loophole is still open as of this writing. It might be your best bet to look into that a bit.
Well, fair enough if you can't be arsed, but it would be a lot easier if you rented it. Would probably save you the time it would take to look into this. Though I guess you'd be paving the way for more like you...
Bleh, do what you want!
Wait, I re-read the first post, and it says with the Twilight Princess Hack! Still not sure what that's supposed to mean though.
It's actually a fair point. I've bought (yes, bought) just five or six Wii games. Too many releases are re-engineered Gamecube games, and on the Gamecube too many were N64 games that they'd managed to ruin.
