Chris Pruett wrote that his wife was well into an RPG when her savegame went bad. He spent three works trying to fix the file in secret, and finally figured it out.
Miraculously, it worked. The continue menu showed stats from the other save, but once loaded her game was completely restored. Between ordering the DexDrive and patching the save, the whole process had taken me about three weeks. That night I booted the game up and showed her the continue menu with the strangely named save. She loaded it up and was very surprised to find her progress, her characters, her stats, and her items all as she left them. She was pretty excited, but before we could talk about it she was off to complete another dungeon.
Use ‘em for good.
