I've got one of those modded Wiis. It's super useful. Can play every (good) NES, Game Boy, Genesis, and SNES game on it. Wii Classic Controller works decently well for all of the above as well, sort of a SNES controller with enhancements.
How is Wii emulation these days? I'd like to play the Castlevania Adventure remake for Wiiware, but AFAIK it's shut down and no longer accessible. I guess I'd need to get a Wii emulator up and running if I want to play it and hope that Wiiware can be emulated without issue.
