I use no$gba to play Pokemon FireRed, and the files are saved in my phone's SD Card(I use Internet Cafes). Anyway, today I opened Pokemon and was going to create a backup for the .SAV file but then the computer restarted. When I reopened it it seemed okay. I was able to play and stuff. But when I put the SD Card back in the phone and opened the memory files(inside the phone), all of the game files disappeared and were replaced by this thing called USBC that takes up 3.3GB. The weirdest part is that the SD Card only holds 2 GB, and has free memory of 1.2GB. I haven't been able to open the file using a computer yet. What does this mean? Any way to fix this?
