Hey guys, I was using my R4 with a program for my EZFlash 3-in-1 called GBA EXPLoader when my DS locked up. I turned off my DS and when I turned it back on, the health and safety message came up and then it went to the loading screen. It stayed at the loading screen and wouldn't boot up. I turned off my DS a few more times, but every time, I got stuck at the loading screen. I took out my MicroSD card and put it into my computer. The computer won't even detect the card. I tried it in another computer and with a different card reader, but the computers don't even detect the card. What should I do? Please Help!
