I have no Wii, but played through nearly all of it a few years back on my PC. Then my girlfriend took a shine to it and I ended up helping her through it until she completed the thing, and I never bothered going back to my game to finish it.

(yesyes, I'm a badevil person for downloading games, but it was never released in Europe and no-one makes any money from SNES games anymore apart from Ebay dealers anyway so take your condemnation elsewhere)
