i'm having problems trying to change the region/language on some of my games. when i try to change the region/language on animal crossing new leaf to japanese or korean, i get a corrupted save data error. on flipnote studio 3d i just get a black screen. however, when i try to change the language to french or spanish, it works perfectly fine. i have no idea what's causing the error, so any help is appreciated ^^ (by the way, i'm not a noob to 3ds hacking, but i'm not too skilled at it.)
