(added a rare "game save" from "mirros edge"... very useful for the examples, is perfect)
(→‎This is a VERY USEFUL game save: mapped the indexed entries from "mirror's edge" game save... from the first 2 tables)
Line 32: Line 32:
The structure of this PARAM.PFD can be considered "rare", and is perfect to be used for explains and to understand how it works, the structure contains all the "problems" not present in "standard" files that can be considered unknown... there are other game saves that can be used (MotoGP10, Heavy rain)... but the list of protected files in heavy rain is HUGE (use this file if you are coding an app as a "stress test", but not for examples)

Sperimental PFD Reader

pfd.c

to compile it just place it inside the ps3tools folder and add pfd into the makefile in the last TOOLS += line

Deroad 20:09, 15 July 2012 (MSK)

The guys at http://us.xploder.net are the first ones that reversed the .PFD structure/encryption/signing

His "Xploder PS3 Cheats System" (is a disc intended to be used in PC) is able to decrypt and reencrypt .PFD files in a PC

In difference with the previous cheat hacks as (Code Freak, PS3UserCheat, E3 GoldenFinger, P3Go Cheat, PS3 Cheat Enabler) this old methods depends of a dongle that patches the firmware to bypass the .PFD checks


By reversing what this disc does we can understand the decryption method

Just a collection of PARAM (.bin .pfd .sfo .tpf) files: http://www.mirrorcreator.com/files/0OAXGOHN/PARAM.rar_links




This is a VERY USEFUL game save

http://db.gamefaqs.com/console/ps3/save/mirror_s_edge.zip

The structure of this PARAM.PFD can be considered "rare", and is perfect to be used for explains and to understand how it works, the structure contains all the "problems" not present in "standard" files that can be considered unknown... there are other game saves that can be used (MotoGP10, Heavy rain)... but the list of protected files in heavy rain is HUGE (use this file if you are coding an app as a "stress test", but not for examples)

From now on... lest use the PARAM.PFD from "mirror's edge "game save" for the examples in the main page
