"DOES NOT WORK WITH LOADIINE FORMAT"
You don't need a wud, you need the encrypted game files from nintendo's servers.
The wud is only in case you don't have to game's ticket, you can extract it from an existing wud (dumped by release groups). Or you can find pre-extracted and already patched tickets on the illegal to share here website ISO.
and if I have a .wud file? can I use this to install the game to HDD?
