Yeah. Also, it'd be great if you could (like Animal Crossing) send your VC game over to the DS temporarily so you can play on the move. It could definetley handle NES, SNES, GB and GBC games, aswell as Turbografx and the Mega Drive.
I think at some point they'll definetly release Gameboy on the wii. They're just waiting for the system to completely phase out, which surprisngly is still a very popular system, even with the DS dominating things. It'll probably be a year or two though.
Well if they do had Gameboy and Gameboy Color games to the VC the Gameboy games should be 100 wii points and Gameboy Color games should be 200 wii points
