So, I just messed around with this a bit tonight *cough*hacked wii*cough*. A word of warning: Good luck playing this on an SDTV. For some reason, when doing so, the writing is very small and hard to read - I have no idea why, considering it's a non HD Wii game. It seems many have been having this problem and without a certain setting on your tv (or a large tv, I guess) you're screwed.
The good news? Dolphin, the Wii/Gamecube emulator, runs a lot better now and is to the point where I can pretty much play it that way. My Core2Duo is kinda slow for it (Even at 25fps euro-style, I'll slow down in some cutscenes), and there still are problems (sound popping at parts, very occasional freezing), but it looks really, really good and someone has even created custom textures so that all the button prompts come through as xbox360 controller buttons for your gamepad. Sweet.
