Can someone please list everything I need to unlock for 100% speedrun, I've heard people say you gotta get 3 stars and some say you don't, just confused

So this run has been rejected cause their accusing me of playing on an iso, something about my time being so good, if theres any way of proving i did this on a wii u please tell me

Hello, ive been playing Mario Kart Wii since the year it was released, I know bassicaly everything to do with MKWII such as the physic and mechanics, it would be super good if I could be a moderator for this game (I originally posted this on another thread but no one has replyed yet)

How can I become a moderator on MKWII???
