A Windows utility for PS3 firmware packages
ps3pupextractor v0.1.1 is a Windows application for unpacking PlayStation 3 firmware update files. The release provides a graphical executable and a ZIP archive asset for the GUI build.
The software runs on a Windows PC rather than on the PlayStation 3. It takes a PS3UPDAT.PUP file and separates the firmware container into its component sections and packages for further examination or processing.
The v0.1.1 release entry contains no itemized change notes, so there are no specific fixes or newly added features to attribute to this build. It makes the documented ps3pupextractor GUI available as a regular release rather than a development build.
Extraction can continue through ELF conversion
The documented full-extraction pipeline begins by splitting the SCEUF container into sections, verifying them, unpacking update_files.tar and processing the SCE packages inside it.
With Full explode enabled, the program can continue through CORE_OS_PACKAGE and decrypt SELF and SPRX files into ELF files. Leaving that option disabled provides a container-splitting mode for users who only need the main PUP sections.
An Include dev_flash option controls whether that firmware content is extracted. The project identifies dev_flash as large, so the option can be left disabled when it is not needed.
Built-in processing and verification
The application includes its documented SCE decryption support, AES-128-CBC and AES-128-CTR handling, zlib decompression, tar processing and firmware key database. It also verifies the PUP header and each section with the embedded pup-hmac key.
The packaged application does not require separate OpenSSL files, external unpacking tools or key files stored in the user's home directory. The README says it runs on the .NET Framework 4.x included with Windows.
The project credits the PUP and SCE format logic to code ported from fail0verflow's ps3tools and identifies public PS3 key collections as sources for its key sets. It is distributed under the GNU GPL v2 license.
Single-file and batch workflows
The GUI accepts a PS3UPDAT.PUP file through a file browser or drag-and-drop. It suggests an output directory based on the input filename, using the name_extracted pattern described in the documentation.
A Batch option can process every file ending in .pup in a selected folder. Each input receives its own output folder, keeping results from multiple firmware files separate.
The repository also documents a command-line container splitter built from ps3pupextractor.c. This is a separate workflow from the packaged graphical executable and handles the PUP container-splitting stage.
What v0.1.1 provides
The v0.1.1 assets are ps3pupextractor_gui.exe and ps3pupextractor_gui.zip. The release notes do not identify changes beyond the availability of this build, so the practical focus remains the project's documented extraction workflow.
Users can choose between splitting the PUP container, running the full extraction path through package contents and ELF files, and optionally including dev_flash. The built-in processing is intended to keep those stages within one Windows application.
The project describes itself as reverse-engineering and homebrew tooling for firmware owned by the user. Its documented purpose is to process PS3 firmware files on Windows, not to provide software for installation on a PlayStation 3.
