WTF has just happened? I've been playing with my DSi with the SC2, playing with the GBA emulator, and then, while using real time save (playing Pokemon Emerald), I got a sudden error. So I turned the DSi off and then on, and it wouldn't let me enter the SC2. After connecting the MicroSD card to the PC, I saw that everything has been deleted. WTF did happen? why did it happen?! Is there any way to bring back the lost files?
