Welp, I don't really know where this thread is supposed to go, so I'll post the problem here. Ok, here it goes: Everything was beautiful. My GATEWAY worked perfectly, the emuNAND did as well. I even got to install some things here and there in that emuNAND. Until one day, the "by-everyone-feared" message appeared telling me that programmes could not be displayed since my 3DS was unable to access the SD card. Of course, it goes without saying that my PC could read it perfectly. After trying to have it repaired and sending it to someone who wasn't Nintendo (I'm not that dumb), I was told that the hardware itself didn't have any kind of problem and that the issue originated from me trying to hack the 3DS. Weird, since I succeeded. So that's it. I've tried looking for a solution, but there wasn't such a thing. I just wanted to know if there's an actual solution, apart from "blow and keep trying" or "buy another 3DS".
