Why is my psp corrupted my game save data?

If your psp console is saying that the game save is corrupt, it means that the game save file is damaged. There is a less likely chance you will be able to recover the corrupted save data, so get over it. The most common reasons why the psp console corrupts game saves is because when the game is saving onto the memory stick, people remove it from the console, when the save is being transferred onto the memory stick. Which results in a corrupted game save because only half of that file got transferred onto the memory stick and the other half got corrupted.
