I'm trying to load Mario maker on loadiine but my wii u crashes and show's me a black screen with a bunch of numbers saying an unexpected error has occured. No error code
For help you really need to give a whole lot more information like what firmware are you on what version of loadiine_gx2 are you using what boot method what region is Mario maker have you tried downloading another version of it ect
Having a similar problem but both the Loadiine SMM and my Wii U is EUR. I don't see why it should crash. Using Streetpass method BTW. I'll edit the post with a photo of the crash in a second.
