Sperimental PFD Reader
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

Y table
Dont forget this table... uses something similar
Is in direct relationship with the X table... the positions of the entries used are the same in both tables
When a entry in this table is not used is "marked" with a "standard" value... for mirror's edge game save is: 5A7EAF6D 029992D0 7580EBCA 42698114 9F2C5DF0

A screencapture of this table with the width fixed (each entry is one row)... there is a total of 57 entries, 25 of them used
http://img6.imagebanana.com/img/q82sh1dj/Ytablemirrorsedge.jpg
The "virtual index"
The addition of the "indexed" entries in this tables makes the total of 33 protected files... are "indexed" by spreading his ID numbers between "X table" and "protected files table"
Ok... more tables... this is the "virtual index" that we have if we place all the entries from the 2 tables together, and ordered by his ID number. This makes a total of 33 "indexed files":
