Externall USB device dev_usb0/PS3/SAVEDATA/<SAVEDATA_DIRECTORY> PARAM.PFD values updated when exported ? (not verifyed)
File Description/Purpose
PARAM.PFD Signatures of some of the files in the folder. The signature method is still unknown.
PARAM.SFO Various information about the title. This one is never encrypted.
Content Information Files Multimedia Files like icons, audio, etc...
Other Files Any other files generated by the game, with any name and extension, e.g: PROFILE.BIN, PROGRESS.SAV etc...

Copy Protection Flag

The ones without "Copy Protection" can be copyed to an externall USB storage device (by pressing triangle over his icon in XMB with the option "copy" of the side menu)

Copy protection can be removed from a Game Save by changing a flag in the ATTRIBUTE of his PARAM.SFO. This can be done when PARAM.PFD doesnt contains the signature of PARAM.SFO (only a few old games)

Games which are unprotected

There are two types of possible protections:

  • One possible encryption in the files generated by the game that is not mandatory and depends of the developers of the game.
  • And other protection based on signatures stored in PARAM.PFD generated and managed by the system. This file supervises signatures of other files of the folder, the list of files supervised is not fixed and again... it depends of the developers of the game, but usually PARAM.SFO is inside this list

This allows modifications/cheats for some games wich files are not encrypted, and not supervised by PARAM.PFD

  • MotorStorm (protected with CRC32 checksum)
  • Call Of Duty 4 (hacked saves can be found on the internet)
  • Battlefield: Bad Company
  • Assassin's Creed
  • Blazing Angels: Squadrons of WWII

PS1 Classics Saved Games

When you copy the saved data from ps3 to psp, ps3 ask if you want to convert it for use with the psp.
