So, I sorta, kind of, successfully changed the emunand of Japanese new 3DS to USA - home menu works, apps boot, it seems all fine except one minor and one major flaw. The first, about half the usual system apps are gone, I imagine something went fucky with the change and I can just install them later. More servere though is pressing home during any game will hard crash the 3DS or give out an error. No idea why this is happening, I followed the guide very closely and I'm at a loss. Any advice on what to do next? Been slaving away on this all day.
