Of course you can get zelda working.
your issue with Zelda not working is : WBFS manager.
I told you, don't use this program. if you want to add a game to a WBFS partition format, use "Wii Backup Manager" instead.
And yes, you just added an ISO, you told me just just re-used the same torrent to add that game again. Sp you just added an ISO of Zelda to the WBFS partition.
but WBFS partition are unstable and easily corrupted.
To fix zelda :
Delete the game from your WBFS partition
use wii backup Manager to re-add it.
Don't add another game after adding Zelda. (Last added game is always working 100%, old games can be corrupted when added new game)
or
use FAT32 partition format, and use Wii Backup Manager to add the game.
With FAT32, no game corruption anymore.
You can convert your existing WBFS partition to FAT32 without losing games, but already corrupted games will still be corrupted after conversion.
Also, do not use any of the "emuNAND" options in the loader with that game.
You almost bricked your WiiU, just because you are using an old partition format...
I hope you will ask for help next time before installing/editing your softmod
