DDolphin is a Gamecube, Wii and Triforce (the arcade machine based on the Gamecube) emulator which supports many extra features and abilities not present on the original consoles. Gamecube and Wii compatibility is good - one can expect "mainstream" titles to run; lesser known titles can be hit or miss. Triforce compatibility is currently limited to a couple of games - others require more of the Triforce-specific peripheral devices to be emulated.
This setup associates the file extensions wad, dol, gcm to double click any game in the Windows explorer and quick open the games.
No games are included, you must have the original game to run it on your PC.
