I've succumbed to Cave Story's Charm.

The Wii version imho is better than the original. You can play the original as is, or play with tweaked music. (It's the same music, but with better quality samples). The graphics are supposed to be tweaked too but I havn't noticed. I wish they could also get this game on DSiWare (or even DS retail). I know there is a homebrew DS port but you need flashcarts (which are questionably legal) and I heard the port was poorly done; also Pixel deserves money.
