Guide to Compile PSN NPDRM Games for PS3 Custom Firmware


Sponsored Links
153w 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.

Thanks a lot, but don't confuse this thread for a Retrogaming thread, next time

p.s. it's not clear which version are those disks. PS? Saturn? PSN?

And write your own idea of this game, don't copy paste from wikipedia, thanks.

Policenauts is a cinematic adventure game, with a hard science fiction storyline published by Konami, written and directed by Hideo Kojima. It was initially released for the PC-9821 computer platform in 1994, followed by remade versions for the 3DO in 1995, and the PlayStation and Sega Saturn in 1996. The game has never been officially released outside Japan, despite plans for an English localization of the Saturn version. On August 24, 2009 (in honor of the 46th birthday of the game designer, Hideo Kojima), an unofficial English translation patch was released onto the internet.

I hope everyone has enjoyed the links I have taken time to find and share.They aren't all PSN but may be hard for others to find. For the last 4 years I have enjoyed the hard word of others and have never been able to say thank you for saving me some time and money. Well this is my way of saying thanks and saving some other people.

Ps any PSN stuff I run across I will post here in the future.

Suikoden II (pronounced SWEE-KO-DEN) is a console role-playing game developed and published by Konami for the PlayStation video game console and the second installment of the Suikoden video game series. It was released in 1999 in North America. The game features a vast array of characters, with over 100 characters usable in combat and many more who move the plot forward.

Suikoden II takes place years after the events of the original Suikoden, and centers around an invasion by the Kingdom of Highland of the City States of Jowston. The player controls a quiet protagonist whose name is chosen by the player (named Riou in the Japanese novelization and Drama CD adaptation and Tao in the manga adaptation); he is the adopted son of Genkaku, a hero who saved the City-State of Jowston in a war against Highland years ago.

The protagonist and his best friend, Jowy Atreides, each gain one half of the Rune of the Beginning, one of the 27 True Runes of the Suikoden setting, and become caught up in the intrigues of the invasion and the dark fate of those who bear the halves of that Rune.
