I've read the stickied guides, but... I'm getting quite a bit of conflicting information. One guide says to stay on 5.3.2 because it works with Loadiine, but is that still the best advice? How can I launch games that require 5.4 or 5.5.x on 5.3.2? Do I have to use Loadiine / Loadiine GX? Any way to load retail discs that come with higher Wii U firmware?
