Beyond those mentioned above, there's Neo-CD redux, which can play NeoGeo CD games.

Those are all that I know of.

Oh, btw. none of these are made for wii. they are made for the Gamecube, but work on wii with a GC controller, nonetheless (Neo-CD redux also requires a GC memcard to boot). As far as emulators made specifically for the Wii go, You've only got the official Virtual Console so far.
