I knew thisone since 5 years already, but when I checked it, there was no games avaiable yet... But nowdays the games which are right now downloadable are impressive! almost every games have been uploaded.
Dolphin is a GameCube emulator but it also works with Wii games! you can connect a wiimote with a bluetooth USB key to your computer and play with a wireless move captor... or set basic commands to a game pad or the mouse/keyboard. I didn't find any Wii game yet... but that's because I didn't seek
I've recently downloaded Metroïd Prime 2: Echoes and it runs perfectly:
Unlike the previous Super NES or N64 emulators, the games are not as "rom" files but as ".iso". But it has absolutely no difference, it's the exact same system to run a game.

I'm not gonna share any games there because it should be seen as warez, but they are enough easy to find everywhere.
