    Sponsored Links
    Can anyone tell me how to do it? (not only for PS1 games but DLC edats and Themes)

    I'm literally clueless here atm, this might help me to decrypt dlc and themes to work on 4.21 CFW.

    Read here, that includes all that's public http://www.ps3news.com/ps3-hacks-jai...-are-released/

    I think that was never made complete though, but some people figured it out, you know who. Unfortunately they were never shared.

    more info here: ps3devwiki.com/wiki/Talk:EDAT_files

    making edat from pkg doesnt remove the license on edats, it just assume that all edats are free edats.

    - at the other side

    I just dig on the source code, yes, this is indeed a java program the decrypt/encrypt edats. I just missing some porion of the program, and need to fill these:
    Code:
    /**
         *
         * Performs checks on the header: -Version check: Must be between 0 and 4
         * included -Flags check: Checks that only valid active flags are set for
         * given version. Ver 0, 1 : Debug and compress Ver 2 : Debug, compress,
         * SDAT, Keys encrypted,.. Ver 3 & 4: Debug, compress, SDAT, Keys
         * encrypted... -Metadata section hash: Checks that metadata section is
         * valid (uses encryption key) -Header hash: Checks that header is correct
         * (uses encryption key)
         *
         * @param rifKey
         * @param data
         * @param npd
         * @param in
         * @return
         * @throws IOException
         */
    I need the rifkey, data, npd and in. I dont know what what to fill on those blanks, I already know the rifkey by just digging on the ps3 dev wiki, but I dont know what is data, npd and in is.

    Use the PS3 eboot resigner, you can install any pkg & then go to Multiman/dev hdd00/game/and find the installed pkg (DLC, PS1, etc) copy the USERDIR to usb & resign it on pc using the tool, then take it back to dev hdd/game, copy & overwrite, it worked for me when i resigned, Crysis, God of war (GOS, COO), Sonic adventures, Coldboot logo, etc. check this:
