I, unfortunately, own a Japanese Wii U in the USA. Wii Party U will load with Spiik but Mii data does not load.

I can use Spiik to get Wii Party U to launch, but the Miis are just black figures with no heads, face, or skin color. Is there any way I can get the USA Wii Party U to just, *work*?
I am using Haxchi on 5.5.5 J

Yes, the US Version did that. so don't bother with it.

You need to use the JPN version, change the language pack and some graphics in the menu. and you are good to go.
