Hello! I have bought a wii u from a guy last week, and it came pre-modded. It’s a Japanese version but with English language applied, albeit not complete - like, error messages are all in Japanese, tv control (which is absolutely amazing) is in Japanese too, and some games after being installed have their names in Japanese. Is it expected or did the guy mess something up and I need to redo the English mod again? Thanks for help!
