So, I've got a nasty problem here. My 3DS will freeze if I will play Kingdom Hearts 3D and then exit into the HOME menu. It tells forever that the program is closing. Nothing happens after. Even if I will close my system or put out my gateway cartridge nothing will happen. Long pressing the power button will power off my 3DS. After all this trouble I get a corrupted save file for the game. What's wrong with it? Do you know how to solve it? I use a gateway cartridge with a 3.0.1 firmware and emunand with 9.4.0-21E firmware. Thank you! *Sorry for my bad grammar. I don't know English much.
