From ConsoleMods Wiki
Jump to navigation Jump to search

If a PS3 is not used to dump a PlayStation 3 disc, the resulting ISO file will be encrypted, resulting in an error when attempting to run the game, usually 80010017.

Materials Needed

Finding a matching IRD file

  1. Find the TitleID of the ISO.
    • This is required as a single game can have multiple releases over multiple regions.
    • If the titleID of a game is unknown, it can be found using the following method:
    1. Drag and drop the ISO file into HxD or other similar hex editor program and find the titleID next to the "PlayStation3" text, OR
    2. Mount the ISO or open it in a file explorer such as 7-zip or Winrar.
    3. Locate either PS3_DISC.SFB or PARAM.SFO and open the file with a hex editor program.
    4. Inside the hex editor program, find the titleID, it will be in the form of ABCD12345 or ABCD-12345 e.g. "BCES00510".
  2. Open a web browser and navigate to Aldo's PS3 IRD database or alternate database.
  3. In the search bar, enter the titleID previously found, and download the corresponding IRD file.
    • If a matching IRD cannot be found, the ISO cannot be decrypted and will need to be dumped from a PS3 console instead of from a PC.

Patching the ISO

  1. Extract "".
  2. Open test_patcher.exe, select the matching ISO and IRD files, and press "Patch" once ready.

Decrypting the ISO

  1. Extract "".
  2. Open IsoTools.exe, and select "ISO Crypto"
  3. Navigate to and select the ISO and select "Open".
    • A file with the extension ".dec.iso" should be created in the same directory as the ISO.
    • This decrypted ISO can now be transferred to a PS3 inside /PS3ISO and played without any extra steps, however for sake of completion, further steps are listed to convert the decrypted ISO back into JB folder format.
  4. Still in 3k3Y, select Tools > ISO > Extract ISO, open the ".dec.iso" file, and in the file explorer prompt, create a new directory for the extracted files to go into.
    • A new folder is created because that will be the folder transferred over to the PS3.
    • The JB folder format game can now be transferred to a PS3 inside /GAMES.
