Guide to Compile PSN NPDRM Games for PS3 Custom Firmware


Sponsored Links
158w ago - Following up on the previous PSN game decryption news, today mallory has made available the PS3Tools NPDRM source code for reactivating PSN content followed by a brief guide from the included ReadMe file below for PS3 Custom Firmware users.

From the included PS3Tools NPDRM ReadMe file:

Based off of gitbrew's 215d8903bc86539ca1da53519e2ac10eeafc4c27 ps3tools. .git folder not included to protect senstive info about the author. Sorry about the messed up tabs, TAB = 4 SPACES 4 LYFE!!!

  • Add the files in the npdrm_keystuff folder to your ps3 keys folder.
  • Create a file with your console's 16 byte IDPS in the 'idps' file in your ps3 keys folder (e.g. ~/.ps3/idps).
  • Copy your PS3's exdata folder containing your act.dat and rif files to your ps3 keys dir (e.g. ~/.ps3/exdata/act.dat). Compile and have fun with your LEGALLY purchased NPDRM games!
  • Also works on free games without exdata/idps.

Apologies for any existing bugs in unself. Adding these changes to unself2 is left as an exercise for the reader.

Thanks:

  • fail0verflow for the orginal tools
  • JuanNadie for figuring out NPDRM
  • euss for his endless hours of work on the wiki

Why didn't you beat me to the punch, Team PS360? I didn't need to reverse a single instruction! It isn't that hard...

v2 info:

  • Added npdrm magic to unself2 and readself2
  • unself2 doesn't like the metadata section with type 3 in my game.
  • This section looks to be some kind of linking information. Here is a snippet: crt0190002crt1190002libaudio_stub190002libaudio_stub190002

I haven't yet looked around to see if this is type of section is documented anywhere.

v3 info:

Unself2 now ignores metadata sections of type 3 instead of aborting. Additional help with any remaining bugs would be greatly appreciated.

I'm sorry if everyone got the impression that these unself/readself modifications can, by themselves, "reactivate" your NPDRM content. These are just the first steps in the process. To those who say this is useless because you need act.dat and rif files: unless you can get unencrypted (debug) or easily decrypted (free, demos) PSN content, the only way to get the unencrypted files is by decrypting it with act.dat and the content's rif file.

There are no "crypto fails" here, proper decryption with the true keys is the only way forward. Using the NPDRM algo with the right keys is the only way to decrypt unless you let GameOS do it for you and hook into GameOS to either grab intermediate keys or dump decrypted content. Using hacks to restore the NPDRM decryption info to jailbroken PS3s is only a partial fix.

For instance, unless you patch vsh or set the SRTC to some time in the past, some content (even non-demos and non-trials!) expires until you log into PSN and reauthenticate. Sorry about your "technical difficulties", Team PS360. You should L2IRC.

Finally, from granberro comes PS3Tools NPDRM PKG Tools Fix V2 (npdrm-fix_v2) which includes changes, as follows:

I'd like to share with you my fork of failoverfl0w and geohot tools. I have fixed some bugs on fl0w tools and added all NPDRM stuff as well as mallory did.

What's different then?

  • unself (unself2 should not skip type 3 section IMHO) is able to save the key/iv used to encrypt the NPDRM and patch the eboot.elf for 3.41 consoles.
  • make_self_npdrm2 is able to encrypt elfs with the key/iv extracted by unself and, theoretically being accepted by OFW>3.55

With those tools, I've been able to "downgrade" LBP2 updates 1-4 and install them on a CFW 3.41.

Follows on the success of Special Edition release of The Secret of Monkey Island, Monkey Island 2 brings back the beloved sequel with exciting new features including high-definition graphics, a re-mastered musical score, full voiceover, and an in-depth hint system. Plus, experience all new unique special edition features that let you interact with the world of Monkey Island like never before.

Having defeated the evil ghost pirate LeChuck in his first adventure, pirate extraordinaire Guybrush Threepwood sets his sights on the treasure of Big Whoop. Legendary treasures however, come with legendary challenges and Guybrush will have to use his wits and humor to prove himself the greatest pirate in the Caribbean.

Voodoo dolls, spitting contests and amusement parks are just some of the challenges Guybrush must overcome as he meets old friends, fights familiar enemies and uses every single ounce of his wits to become the most celebrated pirate ever.

HOW TO PLAY:

1-Install PKG
2-Place .edat file under /dev_hdd0/home/00000001/exdata/

Use MultiMan's File Manager to copy UP0006-NPUB30464_00-CRASHBUY000000NA.edat to /dev_hdd0/home/00000001/exdata/
The folder '00000001' is your user profile id. If you have only one profile -- that is the only folder you'll see under /home/ catalog.
In case you have multiple profiles, copy the *.edat file to the one that you will be playing the game from.
If the folder 'exdata' is not present that means you've never been logged to PSN -- create it manually and put fixed file in it.

The DUPLEX version is OK. And what's the difference of "chapter 0" with the another 5 episodes... is a chapter introductory?

(sorry for my english, I offer to prove all the games in cfw 3,41)


I get the same error code when installing some packages, and I'm in 3.55 Waninkoko. For some like Angry Birds and Crysis I got the error installing the fix, but luckily I found alternative 3.41 fixes that worked. All Duplex releases apparently work fine, but I don't know where this error comes from...

Well this "fixed" version of "The Secret of Monkey Island Special Edition" is exactly the same size as the original release of the unfixed version of the game (429.18 MB). So it probably hasn't been fixed yet, you can try unpacking the .PKG and checking the Param.sfo file to make sure of that but it's safe to say that it hasn't been fixed.
