A port of id Software’s Quake for the Nintendo Wii.

The source code comes from Q1DS (an initial attempt to port the engine to the Nintendo DS), which, in turn, comes from the original WinQuake.

The engine is feature-complete, it plays the game at 30fps with no hiccups or any similar problems. It can also be used as a client for Internet-based gameplay, as a “unmodified” NetQuake client.
