there is a apparently a slight disc speed difference with nintendont than the disc channel on all forms of the wii.

this isnt applying to just sd, this happens with disc too?? i dont have a gcn wii and copy of sms rn but if someone could check then neato

but i have seen instances of faster loads in nintendont from other users

Not only do top runners NOT use Nintendon't, it is completely banned for submissions.

So if top runners used Nintendon't, their runs would be rejected.
