    PS3 SELF / SPRX Decrypter Homebrew Application Arrives

    Sponsored Links
    A few days back graf_chokolo released a PS3 SELF Decrypter PSGroove payload, and today Heden of DeLiGhT has released at PSGroove (linked above) a PlayStation 3 SELF / SPRX Decrypter application followed by an update below.

    Download: PS3 SELF / SPRX Decrypter V0.5 Beta / PS3 SELF / SPRX Decrypter V0.6 Beta

    To quote: Unlike graf_chokolo's method, DeLiGhT's application does not require a special payload to decrypt.

    Simply place the SELF/SPRX you want decrypted into /dev_hdd0/game/DCRY00001/USRDIR/SOURCE/ Then run the SELF/SPRX DECRYPTER from the XMB, and finally retrieve the decrypted files from /dev_hdd0/game/DCRY00001/USRDIR/DESTINATION/

    From the ReadMe File: SELF/SPRX DECRYPTER - V0.5 BETA

    12/04/10 - V0.5B - Initial BETA Release
    - Decrypting internal PS3's SELF/SPRX files
    [BETA - The decrypter hangs on some files]

    GameOS utilizes files to make the console work (I won't give details) These files (SELF = EXE, SPRX = DLL) are stored in /dev_flash. This tool enables to decrypt these SELF/SPRX files. Such a decrypter will only help people who know what they do The application is stable enough even if it hangs on some files.

    Howto :

    First, install the .PKG provided in the archive.

    - Put the file you want to decrypt into :

    /dev_hdd0/game/DCRY00001/USRDIR/SOURCE/
    - Launch the decrypter
    - Get the decrypted files from :
    /dev_hdd0/game/DCRY00001/USRDIR/DESTINATION/

    The current version decrypts only one file per launch.

    Make sure to have only one SELF/SPRX file in /SOURCE/ directory

    This decrypter does not use the grafchokolo's payload nor HV syscalls.

    I believe this tool has been available already long time ago, but author didn't want to share it. Just because graf_chockolo is close to provide the same, this guy released it just to be the first

    I think there are many such secrets in somebody's pocket. But they won't be opened before somebody else will close to do the same.

    Anyway, i appreciate to this author for such useful tool!

    If you can't download attachments it may be due to a setting on your browser, such as a security one or a .zip/.rar file extension association issue.

    Thanks! Time to play

    Tried:

    bdp_disccheck_plugin.sprx - PS3 simply locks on black screen
    bdp_BDMV.self - decrypter shows first two ================= lines and does nothing.
    bdp_BDVD.self - same as above

    For the last two I can press [X] and exit to XMB. For the 1st one - hard reset only.

    Tried some of those in /sys/external and /sys/internal and it worked...

    libdivxdec.sprx
    libsysutil_video_player.sprx

    Same here. I think all this app does is executable the sprx/self and then grabs the data off the memory. I haven't gotten a single a file decrypted..

    IMO it's easier to just use Graf's payload...

    i didn't dig into binary, but i suspect this app does following:

    1) loads self/sprx by usual way, as it would be load for execute.
    2) dump memory occupied by loaded self/sprx into the file.

    since, in (1) it has to execute self/sprx it may produce may side effects and it depends if selected file can be executed in current environment or not...

    It's like file dumper on windows which loads protected executable and then tries to dump it into file producing in most cases non-working executable, so manual work is required to make it work.
