Something happened to my SD Card which resulted in everything in the card turning into .CHK files. Using a backup SD card and data recovery software, I've salvaged some of my data, including save data for DS games played through TwilightMenu++. But what I'm worried about is the save data for the GBA injected games. According to the articles I've found, they're saved to the NAND, but I think that SD cards are involved with the save data too, because the save data were all gone when I used my backup SD card. What can I do to fix this?
Saturday dude.
