I searched around and couldn't find a good answer for this. I just got my AK2i, and I already had a generic 2gb microSD from my phone. I formatted it with the program on GBAtemp, loaded up the firmware, folder for games, etc. When I went to load it, however, it got stuck on loading. I read through the forums, and I read that if all the fixes didn't work, that it's most likely a hardware issue, and to return it. I was hoping to clarify something before I tried to return my AK2i - does it require a certain brand of flash card to work? I had an R4 with my DS Lite and I used a Kingston SD card, and that worked fine. Should I try using it with a Kingston or SanDisk SD card before returning my AK2i? Thanks.
