So, I played through a few games for a few hours on each. saved a few times, it held my saves fine. But then later, when I tried to save again. It said it saved, showed my new save times in game and all so I thought it was fine. Turned it off, later when I tried to reboot my save, it loaded back to a much earlier save. I am running on a Supercard ds1i. Any ideas on what caused this or how to fix it?
