LibRay

LibRay: A portmanteau of Libre and Blu-Ray

LibRay aims to be a Libre (FLOSS) Python application for unencrypting, extracting, repackaging, and encrypting PS3 ISOs.

A hackable, crossplatform, alternative to ISOTools and ISO-Rebuilder.

Note: this is still a very beta project, report any bug you see!

How to install

Note: You will need Python 3, so you might want to use python3 and pip3 instead of python and pip depending on your system.

From PyPi:

sudo pip install libray

Manually:

Clone this repository git clone https://notabug.org/necklace/libray
Install dependencies with sudo pip install -r requirements.txt
Run sudo python setup.py install

From AUR:

For Arch or Arch-based GNU/Linux distributions there's an option to install libray from the AUR (Arch User Repository).

You will need an AUR helper (of which there are many).

Then you will need to run the appropriate install command for that AUR helper using libray-git as package name.

This will essentially automatically do the manual method for you.

Done!

libray is now installed to your path.

How do I use it?

usage: libray [-h] -i ISO [-o OUTPUT] [-k IRD] [-d DECRYPTION_KEY] [-v] [-q]

A Libre (FLOSS) Python application for unencrypting, extracting, repackaging,
and encrypting PS3 ISOs

required arguments:
  -i ISO, --iso ISO     Path to .iso file or stream

optional arguments:
  -o OUTPUT, --output OUTPUT
                        Output filename
  -k IRD, --ird IRD     Path to .ird file
  -d DECRYPTION_KEY, --decryption-key DECRYPTION_KEY
                        Manually specify key
  -v, --verbose         Increase verbosity
  -q, --quiet           Quiet mode, only prints on error

First off, even before you install libray, you will need a compatible Blu-Ray drive that can read PS3 discs.

There's a compiled list of compatible drives here: https://rpcs3.net/quickstart (archive) (see "Compatible Blu-ray disc drives section").

On some systems (eg. Linux), you can decrypt directly from the disc.

libray -i /dev/sr0 -o ps3_game_decrypted.iso

Libray will automatically try to download an IRD decryption file for your iso. If you don't have internet connection, but you do have an .ird file you can specify that:

libray -i /dev/sr0 -k game_ird_file.ird -o ps3_game_decrypted.iso

Alternatively, you can first rip the disc to an ISO file and then decrypt from the ISO file:

libray -i ps3_game.iso -o ps3_game_decrypted.iso

Then, if you want to feed it into RPCS3 just extract the contents of the .ISO:

7z x nfs_ps3_decrypted.iso

And move the resulting folders into the appropriate folder for RPCS3:

Linux: /home/username/.config/rpcs3/dev_hdd0/disc/

Error!

Help! I get

ImportError: No module named Crypto.Cipher

ImportError: cannot import name 'byte_string' from 'Crypto.Util.py3compat' (/usr/lib/python3.7/site-packages/Crypto/Util/py3compat.py)

This is due to multiple similarly named python crypto packages, one way to fix it is:

sudo pip uninstall crypto
sudo pip uninstall pycrypto
sudo pip install pycrypto

If you get any other errors, or have any other problem with libray, please create an issue!

Development

Todo

Extract ISO (currently doable with 7z x output.iso
Repackage (unextract) and reencrypt iso?
Test .irds with version < 9
Custom command to backup all irds available
Unit tests
