Kingdom Hearts Birth By Sleep

[roselian]

Hi, can anyone help me? I was at the keyblade graveyard with Aqua, about to finish the game, but when I opened up the emulator this morning (I keep it on a flash drive), and tried to play it, the game wouldn't load the file, and said that the save file was corrupted. I use the save state as well, to back up my game, but no dice--it's also broken. That one says "Error: After "RAM," found 0 (0x0) instead of save marker 66 (0x42). Aborting savestate load..."

I've tried moving the files to my computer to run them, but the same thing happens. I cannot restore earlier versions of the flash drive, and my most recent backup before this (saved to my computer) is in Radiant Garden, and I've already had to play Deep Space, Olympus Colosseum, and Disney town three times, because my laptop kept crashing (which is why I moved the game to a flashdrive in the first place.) Is there anything I can do to fix the files? Either of them?

Thank you in advance.
