RGL Extractor

A tool for extracting content from Rockstar Game Launcher's (in short RGL) RAGE Packfiles (mainly just Launcher.rpf at this moment). RGL uses RPF7 (like GTAV) but encrypted with a different AES key. The key is obviously not included, but the tool can automatically find it in Launcher.exe. This tool was created only for educational and data mining purposes.

How to use

• Download the latest available release.
• Unzip RGLExtractor.exe
• Run the tool and pass required arguments. For example: .\RGLExtractor.exe --rgl "C:\Program Files\Rockstar Games\Launcher" --out "C:\Launcher_rpf"

Building

Download and install Go (1.18+) toolchain.

# Clone and build.
git clone "https://github.com/Disquse/RGLExtractor"
cd RGLExtractor
go build

# Extract Launcher's RPF content.
.\RGLExtractor.exe --rgl "C:\Program Files\Rockstar Games\Launcher" --out "C:\Launcher_rpf"
# Decrypt title.rgl files (recursively).
.\RGLExtractor.exe --titles "C:\Launcher_rpf" --out "C:\titles_rgl"
