This is really odd. I tried loading up a rom and all I got was a white screen. So I shut off the system and turned it back on. Except, now, all but two of my roms are listed anymore. The others just vanished. I was looking at the card on my computer and it said that data was still taking up space, but the roms just went there. It said I was taking up 475mb but there's only 115 megs of data on the card! So what happened? I don't know if it matters, but I have an A-Data 512mb MicroSD card.
