would nintendont be allowed for my speedrun on wii u because i don't own the phsyical disc and wii u wont allow it

Nope, Nintendont will mess with loading times and is banned, therefore runs from WiiU are not a thing right now. We check the loading times for the submissions.

Please get a disc if you want to be on the leaderboards. To practice and for yourself you can obviously still use it :)
