Luigi bug was confirmed a few pages ago. Do you have rogue squadron 3? If so see if you start all ground missions crouched. I think it's a related bug.Does anyone else have issues with Animal Crossing (NTSC)? With me it kicks out of the loader partway through the opening Nintendo logo announcement. "Nintend-*reset*"
And with Luigi's Mansion (PAL), the vacuum seems to always be going with the classic controller and Wii U Pro Controller? Haven't tested an actual GameCube controller yet.
I reported these on the compatibility list, waiting for anyone to confirm.
It'd be interesting to try setting an Action Replay iso as Disk1 and a game as Disk2.
