So I've already downgraded my 3ds to 4.2 and installed cfw on it. Everything is fine except I wanted to play my retail games, so I updated muy emuNAND to 9.4 with the MT card launcher on another sd card. However, everytime I try to boot up my retail copy of smash 3ds in classic mode, I get a black screen. I even tried installing the game's update from eshop, but I still get a black screen. Anyone have an idea how to get it to work?
