First of all, hello. Second, I need help. My R4 card (WOOD firmware) has stopped working recently. I had just put on some new games so I could test out some AR codes and they had worked perfectly. Today, I tried again: "Couldn't find DS_MENU.DAT" upon startup, so I checked out what was up by using my SD reader, all of my files were corrupted. I tried deleting them, error message. I tried copying a backup of my files into the SD card, error message. Now I'm wondering whether or not my SD card is busted, if anyone knows a solution, please tell me.
