Backup Save State

[[Unknown]]

If you rename the file (removing .undo), it should be able to load it. If it still can't load it, that may mean something corrupted the old state too.

I strongly suggest making normal in game saves, as save states simulate a situation PSP developers didn't test well: playing games for hours on end without restarting the game. Just like sometimes issues with a computer can be fixed simply by restarting it, some games have bugs when you run them too long in one sitting. A save state just keeps that going from a game bugs perspective.

In game saves are also more portable between PPSSPP versions, different PSP emulators, or even real PSPs. They're just better, except you can't always make them from anywhere.
