Thanks for your fast response!
What kind of glitches do I have to expect? Game breaking glitches or just some minor graphic glitches?
Is it also possible to mod the game and play it on Dolphin (on PC). I do own a Wii and the original version but it would be way easier for me to do it that way.
Yes it can freeze your Wii, Yes you can play it on Dolphin (But you would need to ISO hack instead with WiiScrubber)
