Hello there I have a similar issue with my Sapphire version save. I was trying to make a trade between my Sapphire and Ruby versions and one of the gameboy froze in the process of transferring the pokemon I turned both gameboys off tried trading again and the gameboy froze again so I kept retrying and on the next reset my Sapphire save was gone and it gave me the"save file has been deleted" message. Am I still able to recover my save file?
