I got it yesterday, and it was working perfectly fine until about 30 minutes ago. The only thing I that I've done to it recently was make the CycloDS folder hidden in Windows, and I put on a ROM of pokemon platinum. Now when I start it, it shows the loading screen but the bar doesn't move at all. I went and deleted the Pokemon ROM, and changed the one folder to not be hidden anymore, but that didn't do anything. Is there anyway to fix this? I have Hardware version 1.1, and am using the 1.55b firmware. I also have a Kingston class 4 microSDHC 4GB card. Should I try updating the firmware to the same version again? Different version? Maybe reformat the SD card?
