So the title kind of says it all, after installing both EU and USA versions of the game on separate occasions both of them failed to boot past the main Splash Screen. I did some research and some people said that the culprit was something regarding regions? So I got an app called Spiik and that didn't work out either, any of the configurations I tried. Some said it was the DLC I got with it but that didn't work either. Some further details, I have a Japanese Wii U on 5.5.3J, The latest homebrew and HBC, Haxchii, and a Black 32GB Model Wii.
