100 Mario Challenge Super Mario Maker ?

How to i get to play the 100 Mario Challenge on Mario Maker?

I have the latest version of Cemu,and Version 16 of Mario maker. The game loads fine,and i can play the 10 mario challenge but i cant play the 100 masrio challenge.

Can you not do that anymore because you may have to be online?

I would love to play all the online user created courses but i heard you cant do that anymore either.
