PKG extractor

Since 0.3.3 the launcher ships pkgextractor.exe beside it, and an Extract PKG button that drives it.

Included with PS5PCEM 0.3.3, pkgextractor reads supported PS5 debug packages (FPKG / FIH), writes sce_sys metadata, and extracts application files from the inner PFS, including observed NAPS layouts and Kraken-compressed payloads.

Retail packages are out of scope

The extractor reads the debug FPKG layouts that were observed during development. Encrypted retail packages are not supported, and no keys are included or implied.

GTA III: complete package extraction

The October 2 development extractor fixes InvalidPfs for GTA III: The Definitive Edition (PPSA03527 v1.007). All 48 files extract, including eboot.bin, six modules and both PAK archives; both PAK index checksums match. All 21 package tests pass. The game was not launched. This fix is in the development source and local tool; published release downloads are unchanged.

How to use it

  1. 1

    From the launcher

    On the Library tab, choose Extract PKG, pick a .pkg file, and wait for the console window to finish. The output folder is created next to the package (same name, without .pkg) and becomes the selected game folder.

  2. 2

    From the command line

    Run pkgextractor.exe beside ps5pcem.exe. If -o is omitted, the tool writes to a folder named after the package stem.

  3. 3

    Then launch as usual

    After a successful extraction, select the output folder like any other dump. Supported debug packages include eboot.bin, sce_module files, and the inner application assets. Extraction alone does not guarantee that a title is compatible with the emulator.

pkgextractor <game.pkg> [-o <output-dir>]

What it handles

  • eboot.bin (uncompressed SCE_DYNEXEC SELF from the nested pfs_image.dat)
  • sce_module/*.prx (other uncompressed SELF modules from the same image)
  • Inner application files, including supported Kraken-compressed blocks and NAPS-mapped payloads
  • SELF dynlib-data tails required by the extracted executables
  • sce_sys/param.json (title id, content id, localized names)
  • sce_sys/icon0.png and pic0.png (and their DDS siblings when present)
  • PlayGo tables (playgo-chunk.dat, playgo-hash-table.dat, playgo-ficm.dat)
  • Trophy and UDS archives when they are stored as unencrypted CNT entries

What it does not

  • Retail packages (FIH signed byte 0x80 / CNT-only retail images) are refused. They need console image keys that this project does not ship.
  • Support covers the debug layouts observed in local tests; unfamiliar or damaged packages may still fail to extract.
  • Encrypted CNT entries (licenses, some npbind records) are skipped rather than written as garbage.
  • The tool is for dumps and debug FPKGs you are legally allowed to access. Game content is not included with the emulator.

Use only content you are entitled to use

No games, console firmware, system libraries, keys or vendor material are shipped with PS5PCEM or offered here. The project exists for interoperability research and education. The full legal note.
