I have already read that repacking modded games with either nuspacker or WiiUInstallerPacker just don't work, but my question is why exactly it doesn't work? Is it related to the cert, tmd or tik files? or is it related to the way the wiiu handles the game installation? I would like to get a more deep understanding of why the repacking and installation of modded games isn't working right now and maybe try to find a way to make it work. So, if possible I want this thread to stay focused on the tools for repacking/installing and what is missing/failing right now instead of just comments like "install the original game and then use wupserver to copy the modified files". Thanks for your time.
