I have the same problem. And yes, it's very annoying because image quality it's incredibly bad.
Will be amazing if someone manage to fix it, but i'm not optimistic.
Sooooo... If I follow all Punderino's guide steps but powering off my Wii U after dumping sector 1090000 then should be possible to have a working rednand? Maybe I'll try it.
Thank You!
@Xdqwerty, to answer your question, they're a fusion Brit-pop/J-pop/electronic band with a woman vocalist. Flamingo is hands down their best known song but they've got a ton of other really good songs
