I saw an old post here (https://www.speedrun.com/go_vacation/thread/ixbvj) which resulted in WiiU being added as a console. The console option "WiiUBC" is now recommended for runs on WiiU using Wii discs (this option didn't exist four years when the forum post was made).

See this post from another game: https://www.speedrun.com/skylanders_giants/thread/3dk1v/

WiiMini could also be added as a console, as Wii games are playable there.
