PS3 Save Game Unlocker

French Developer corwin75 has created an application that lets you edit your game saves, here is a quote from the release thread:

Hello.
It’s complicated you change your ps3 saves by lack of knowledge or you have simply no hex editor? The solution is very simple. PARAM Edit is a small program that I just create to modify your saves in several areas:
- Modify the protection of saves (lock / unlock copies)
- Make compatibility saves with your account
- Modify the saves details
- Change the title of the saves
- Edit sub-title of the saves
Sources are being modified to be especially easy to read and understand each operation.
EXPLANATION:
For compatibility. You need a save to make it compatible with a game and a save from your account with the same game.
