I used TunesKit Video Repair to fix corrupt mp4 files. It is the easiest video repair tool I used. And it is compatible with 25+ media formats, which can meet my needs.
Make another one
In Emulators you can't fix the corrupted Data, Just in the GBA or GBA Sp
It depends what file was corrupted. The Xbox did nothing, but an update may have fixed it.
Try redownloading them.
gamestop
delete the data and puted in your psp
im afraid you cant fix it.
sorry but you will have to restart your game.
tell the police and/or contact sony or the company who made it
Reinstall the game.
Best thing to do is delete it and redownload it from the PSN.
ussually it will load the last save game and it will fix itself
