It's the same for me, but in my case sounds a loud noise and then it frezees :(, any idea how to fix it ? i'm using mii maker mode without NNID linked.
Even works:
New super mario + luigi u
Game and Wario
Wii party U
Nintendo Land
Nes remix pack
;)
auto
Mario 3d world works But very Sloooow... around 16 seconds to load a stage
If there will be a port of version 03 when it comes out ? and so with future versions. I want to play 3d world without waiting so :) you know, it would be great if it happened.
