Sean's quite right. The Wii Freeloader was blocked with update 3.3 on the wii, so although it DID work for some GC games (not all) it won't work now unless you prevent 3.3 from loading.
Gamecubes are criminally cheap now - I agree their going rate is £15 in various game shops or online. Grab one and enjoy!
I'll never part with mine, mainly cos I still use the Gameboy Player to play my old GameBoy Advance games on the TV. How cool is that!
