could be write privileges. I've changed icons and whatnot (like I did with redNAND). beyond that, I haven't really messed with other game files (other than tickets). I think you have to apply privileges with wup server, which is what I was using. ftpii u everywhere may need that too.
you can change individual graphics for games: https://www.psx-place.com/threads/correct-save-settings-for-tga-files.13082/
that's something I posted a while back. changing the folder icons themselves -- I know of no way to do that. you'd probably have to reverse engineer it, which is more a pita with the wii u, since it doesn't have a lot of safeguards in place if something went wrong. the icons for games -- a corrupted or incorrectly saved icon will prevent the game from booting.
What do you mean by "correct" version ? Isn't it the correct version automatically, if it allows you to see the file system of the WiiU ?This may be dumb but did you load the correct version of Mocha CFW before launching FTPiiU?
theres 2 versions of FTPIIU,one for the HDD or SD only and the other for the NandWhat do you mean by "correct" version ? Isn't it the correct version automatically, if it allows you to see the file system of the WiiU ?
