I know this hasn't been replied to in close to two months, but I feel compelled to at least say something about one of my favorite games ever on this board. First of all, the "weird" remixed music actually really is messed up, as explained in this link
and I guess they just never could patch it. I've heard they were gonna fix it and maybe some other things for the EU and JP releases but I never did get info on if that was true or not.
Also, if I'm allowed a shameless plug, I actually wrote an FAQ a couple months back for the game, using the WiiWare version as a basis
. I did originally play it on PC a few years ago, and I still prefer that version for the lack of bugs and the modability, though I think the new modes and wonderful upgraded graphics are enough to toss a few Wii Points toward buying the Wii version.
And yes, this game is really, really good. Especially when you remember that it was originally created wholly and in every aspect by one single man, and that the most substantial addition to the Wii version by far, the upgraded graphics, were, again, all done singlehandedly by that same man.
And Mimigas are adorable.
