We just bought a used Sapphire and FireRed GBA game for my 7 year old's DS. He plays the game, saves it, and turns off the DS and/or removes the cartridge. However, we he comes back to play again, he continues to get the message "Saved File Has Been Deleted." I haven't been watching him closely to see if he has been missing a step, but he continues to have this problem and I am concerned as we bought the games used off Ebay. Is there a simple fix or is he doomed to lose his progress?
Thanks for any advice.
