..it only seems that voice is kinda broken.
Everything else seems to work just fine straight out of the box. (text entry, textures and stuff like that)
Broken music and voice
The music and the voice of Nia is too slow in-game. Enable RDTSC in Options > Experimental to fix this.
Weird texture issues
Some textures do weird things and some don't appear at all. There's no fix for it.
Flickering Geometry
Go to CPU > Mode and select "Single core interpreter" to fix this issue.
Text entry
To fix the name entry, install the keyboard-related System RPL Files you can dump from your Wii U.
Configuration
Go to CPU > Mode and select "Single core interpreter" to avoid flickering geometry.
Some texture and shadow glitches, some sounds are disorted.I used graphic pack 1080p and the game cuts the image to a square in a corner of the screen, while the rest is black. In local battle using the GamePad view slows down the gameplay, and P2 buttons are mixed (pressing "A" acts like "start", "D-pad Down" acts like "R" etc).
Works fine, some control remapping is required and there are visual issues like shadows in fights, but it runs at 60 most of the time and it's perfectly playable so far.
