PPSSPP Feature Request Page

[LunaMoo]

As long as I understand this^ from automatic translation, you want a feature to fix corrupted or broken savedata - that is impossible since trully "corrupted" or "broken" savedata isn't recoverable in any way.

That being said PSP games do report savedata as "corrupted" also when it's just encrypted with different/outdated key. PPSSPP has full control over it and doesn't need any plugins, homebrew nor generating files to deal with such situation, the game will create an updated save on it's own as long as it will be able to read and load it in the first place and not long ago I added an option for it.

A short guide how to use that feature can be found in here, but again this solution, same as all the homebrew claiming to "fix" savedata exists for very specific problem that nowadays would show up only in rare situations like transfering savedata from some old memstick last used on horribly outdated PSP or downloading very old saves from sites like gamefaqs.
