Twilight Princess HD Project is a Project (more than just one) to turn the GC game "The Legend of Zelda: Twilight Princess" into HD. This is the version of the GameCube we are talking about and not for the Wii.
The first project is not yet complete, something I hope will be done soon as I wanted to play the game, but the Wii was asking me to get the extra adapter for the controller, which I did not want to do to play a game. The 2nd is however complete.
Check out some photos and videos below.
You can try them out without being complete. You must have the iso of the game (search it on google) as well as:
-The right patch
-The right Emulator
