I've learned someone else was having the same problem as me. So the problem is when I tried to check my saves through bios and to my memory cards, all my saved games are all there. But the weird thing is I can't load them within the game themselves, it's like the game can't detect my saved files. And there was this suggestion that we should delete any saved states from the folder. I already did but didn't work.

It's very frustrating, I need help for this.
