I don't really know what you're talking about, (I'm still a little new to the WiiU homebrew/hacking scene) but I downloaded the updates/dlc through WiiUUSBHelper
So everytime I install the DLC for Zelda Botw I get an error (not with a code just the WiiU telling me that the "additional content" is broken and needs to be deleted and reinstalled.
I'm using WUP Installer GX2 with Mocha CFW.
So I downloaded the update for Botw from WiiU USB Helper and now I'm trying to install it. The problem is I have multiple subfolders in the folder wich looks like this (pic below). I really have no idea how I am supposed to make this installable :/
