NNGC (probably standing for New or Next Nintendo GameCube) was an internal codename for the Wii project, used before the "Revolution" (RVL) name was decided on.[1] It is referenced in various places, including the names of the NDEV USB drivers and game files of The Legend of Zelda: Twilight Princess. It has been theorized that the NDEV's full name is "NNGC Dev".
