Doesn't the Wii shop come with an SNES emulator, too?
I got the C64 emulator with California Games, and BubbleBobble arcade for the Wii and they both still rock harder than any of my (mostly bargain) Wii games. The only game we actually really play is WiiPlay. For X-Mas I'll get the kids WiiMusic.
I also got the SuperMarioBros. NES on the Wii. Still one of the best J&R level designs.
Also, Kickle and Adventures of Lolo are great puzzle games.
Ice Climber is classic! There was a knit-machine for the NES, and they had the first
dance matsI never liked Excitebike, but the remake "Joe Danger" makes me weep for not having an X-Box.
BTW: Who'd have thought in '95 that Sonic can be played on a Nintendo machine...
