Guide to Compile PSN NPDRM Games for PS3 Custom Firmware


Sponsored Links
166w 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.

er i'm not much on "flash" thingy, meaning i need another ps3 for this?? or format mg HDD in my ps3??? T_T

i think i got it work, i used the pkgview_1.2, extract it it, got the folder NPJB00134, put in the external storage, then in multiman using filemanager, i copy the NPJB00134 from the usb to the dev_00 (something like that) in the games folder (all lowercase), then after exit i dnt see the game in the games folder, but once i apply the fix, IT WORKS!!!!

so happy, luckily already have the game with saves in it..oh joy

sometimes that error comes from the flash memory you're using. I had the same problem once and solved it with using another flash. I could install all other packages using the same device but only one gave me error.

so either use another device or format the one you have then use it.

Got it, mate. After looking at what there is in the 1.01 update, there really isn't anything that is significant (all about repeat and shuffle) so I am all happy! Thanks again, propJoe, really appreciate what you are doing here!

Just curious, what is the "DLC" section in Dreamy Theater 2nd? Is that something we can transport through psp? Because I remember I have the DLC (not the PD1) for hatsune miku project diva 2nd (PSP), but I don't know how to transfer it to PS3... Or it currently won't work like that?
