    Well U need to change the file param.sfo from gt game data to BD then u can make the structure of the game like it was just by copiying files and folders like the image below ie create a folder wit the name of the game Let's say bleach inside that folder u need to put disk.fsb file + PS3_GAME folder. inside PS3_GAME u copy or cut and past folders inside the converted game into PS3_GAME and that's it. I'll make a small tutorial if things are not clear ^_^

    @mcshooter @PattrickH files need to be decrypted cause they are encrypted with NPD header if you drag any file in Hex Editor from CFW2OFW game inside USRIDR

    GTA 5 BLES01807 for Exemple ps3.rpf :

    Capture d’écran (4968).png

    cause when you convert a CFW Game to OFW using CFW2OFW Helper for exemple the "make_npdata" do an encrypt operation with this command :

    make_npdata -e "Input FileSource" "Output FileDestination" 0 1 3 0 16

    make_npdata (Tool to encrypt/decrypt/bruteforce EDAT/SDAT)
    -e (Encryption mode)
    0 (SDAT Format)
    1 (Finalized data)
    3 (EDAT/SDAT version 3)
    0 (Without compression)
    1 6 (Block size in KB)

    to decrypt SDAT/EDAT file you must use '-d' command to make decryption mode like PSN Games using make_npdata -d command :

    make_npdate -d "Input EncryptedFileSource" "Output OriginalFileDestination" 0

    make_npdata (Tool to encrypt/decrypt/bruteforce EDAT/SDAT)
    -d (Decryption mode)
    0 (Klic No key)

    You could just install the last update instead. So eboot runs from dev_hdd0/game like its meant to.

    so change param.sfo, repack to ISO, then install last update pkg to play it.

    Much simpler to delete the CFW2OFW game, re-rip the disc using a backup manager giving you a JB folder format game (ie original file struture from the BD disc) then convert to ISO if you want to ... simples... no messing about.

    Then if you want to play online with it you then install the latest game update pkg..

    @Louis Garry of course but command must use 1 for klic (NPDRM OMAC key 1 (free license key)) and not 0 (No Key ) or it will show error

    Command :
    make_npdata -d "NPEB01807/LICDIR/LIC.EDAT" "PS3_GAME/LICDIR/LIC.DAT" 1

    no LIC.DAT :

    upload_2019-10-22_12-58-22.png

    error using 0 as klic (No Key) :

    Capture d’écran (4978).png

    and no using 1 as command (Free Licence) it works :

    upload_2019-10-22_13-1-17.png

    LIC.DAT in HxD :

    upload_2019-10-22_13-3-57.png

    Edit : man i decrpyt LIC.EDAT to LIC.DAT and then rencrypt it again with -e command and now i can decrypt it with 0 (no Key ) command

    nice men I will try this with a make_npdata v1.3.4 version that I found in a Russian forum, I encrypted a fifa home patch and delete the original data now the links are gone, it is a good way to learn although I give it very little use To the cmd most of the ps3 programs that have an cmd interface usually have numerical options that make things easier for you, I used to use the terminal in a Linux-based software to do network tests, let's see how it goes, it's always good to learn something new.

    As an exercise, I tried to recreate the command as it is shown here, creating the same paths in the directory with all the files in place, but I still have the error Please check your input file! This program has options for edat but it encrypts virtually all data from cinematic m2v to txt files, how would you decrypt all the contents of a folder? This is the command that gives me an error (C: \ PS3 \ make_npdata -d "NPUB31616 \ LICDIR \ LIC.EDAT" "PS3_GAME \ LICDIR \ LIC.DAT" 0)

    I already solved it by placing an executable of the cmd in the folder where the program and the files are, thanks.

    i've edited a batch script (the old game_convert.bat) to do the reverse process, and seems to work well with cod bo2

    Just extract it with next to where your NPUB Folder is, open it and it will ask you for the Folder Name
