EDIT: My bad, the software name is Wii U Installer Packer. Not NUS Packer. So I read somewhere in this website a tutorial on how to convert loadiine ready games to USB format (or the brazilian method, as many like to adress it). At first I couldn't even dump the game from my console with DDD, so I skipped that part of the guide and just grabbed a VC game from my obsolete loadiine folder and gave it a go but when I tried to repack it with Wii U Installer Packer nothing happened there was no output folder with the converted game. And yes, there is a meta and content folder on the GAME folder.
