Hi, its my first time posting on gbatemp and my english is not so good, anyway, I'm trying to install black ops 2 on my wii u and only got some WUX file, then I transformed into a WUD file, but how can I put this game on my wii u? He is modded with homebrew and I already installed some games using ACOWUP Downloader and it don´t have black ops 2 title key, so anybody have an idea about how to install this game?
