However, there was one homebrew app called 'Spiik' which changed mario kart 8's loading screen issue from ending in a loud abrupt noise to a never ending loop of engine noises. No homebrew software fixed the issue of not being able to actually load mario kart 8. I used all kinds of region-lock related homebrew apps. the game wouldn't leave the initial loading menu. As exciting as this accomplishment was, there was one issue. I changed the region code in a system xml file in my wii u' system files and was able to successfully initiate the game booting process via the disk application.
I was worried initially that it wouldn't run on my pal region wii u (and it didn't.) I decided I wanted to make my wii u region free. A friend of mine recently gave me his usa copy of mario kart 8.
