It's been driving me crazy that I can't save a couple of games; the new Coraline game and Sonic Chronicles : The Dark Brotherhood. When I want to save it a message pops up and says; "The save data could not be accessed. Please turn the power off and reinsert the DS card." I've installed the latest update and the cheats but to no avail.. I dunno if I installed the update correctly. I'm on a Mac so when I extract the firmware, I just drag and drop it into the SD folder. I have no idea where the root of the SD card is, so can anyone help me? Please? Thank you!
