So I have CBHC on my Wii U and a Nintendo Network ID linked to my sole User on the system. I want to unlink the NNID so I can delete it cause Nintendo is a pain in the ass and I don't have a random spare 3DS to do this with where I can quickly link up the NNID and delete it. How the hell do I unlink the NNID without losing anything on the Wii U?
