Alright, I apologize if this is not the proper place to seek help, yet I did everything I could to resolve my issue myself yet have reached a dead end. I am using an Acekard 2, and just updated to 1.4.1 yesterday. I played a game with it for 4-5 hours yesterday, then left it to charge. When I tried to load it up today though, the card refused to boot. After the DS Health warning, I get the loading indicator quickly, then both screens flash white for a split second and then turn black. After that, they stay like that. Following the most relevant instructions on the wiki, I tried reloading the SD micro card into the Acekard many times, and also reloaded the Acekard in the DS many times. I also reformatted my SD card (on a Mac, so no Panasonic utility, yet it should be formatted just fine in FAT 16), reinstalled AKAIO and one rom tester file, but all with the same result. I also tried loading the official Acekard 2 firmware, which loads and then freezes. I do not have access to another DS or micro SD, so I cannot easily test whether this is a flashcard issue or a software issue. Can you guys please advise me? Thanks a lot!!
