Does your version fix the boot.dol not found error that occurs even when nintendont can successfully be launched and run the game but still occurs in the latest free version?
It does not. That issue that you're seeing has to do with your Wii U. Usually it has to do with some homebrew that you're using. Look at the FAQ, it says what homebrew to stay away from because it can cause issues.
Also, I want to make note that this is a separate build from the Official UWUVCI version, this one has zero involvement with the original creator.
