That's almost right on the Wii U scene. People are bashing Hykem on that scene. Nintendo console scenes are the worst. When I had a PSP (which I almost never played), the scene wasn't bad at all. They were great, and trying to help others, even if it helped to piracy. They were trying to learn things to other developers to be better at hacking software, understanding things, reverse-engineering and all that stuff.
I was a KTM beta tester too. One of the main reasons it wasn't released is that I had an unique issue on my 3DS, too. fs::USER was acting strange. KTM couldn't extract the ZIP file from the TTP and extract its content to the SD card. It had a strange error, which happens sometimes on ironhax/oot3dhax installers too.
