So my friend just got the Light Baby Blue NDS and a R4DS from China the R4DS was working fine until tonight when we were about to play some Tetris it had a problem with reading the SD card. Ok no problem, I borrow his SD card and R4DS to see what's the problem. Apparently the card was corrupt so I reformatted and reinstalled everything. But when I tried it again it gets stuck on the Loading... screen. Any ideas as to what I should do?
