Pkg2zip, an utility that decrypts PlayStation Vita pkg file and creates zip package.

Supported pkg files - main application, DLC, patch, theme and PSM files. Also supported PKG, PSX and PSP PKG files for use with Adrenaline.

Optionally writes NoNpDrm or NoPsmDrm fake license file from zRIF string. You must provide license key.

Features

• Portable, written in cross-platform C code, runs on Windows, GNU/Linux, macOS (system dependent functionality is isolated in sys.c file).
• Small, has no external library dependencies and uses very minimal dynamic memory allocations.
• Fast, uses AESNI hardware accelerated AES decryption if supported by CPU (requires AESNI and SSSE3 instructions).
• Simple, creates zip package with same folder structure that Vita expects (just drag & drop all file from zip archive to ux0:). Zip file is created directly from pkg without any intermediate temporary files.
• Vita DLC, Vita PATCH and PSM pkg unpacking.
• PSX, PSP, PSP Updates, PSP DLC, and PSP THEME pkg unpacking.

Limitations:

• no actual title name is extracted for PSM pkg files.

User guide

Requirements

• HENkaku / enso.
• NoNpDrm.
• NoPsmDrm for PSM titles.
• VitaShell v1.76 or newer required for DLC installation.
• Adrenaline for PSX or PSP titles.
• Npdrm free for PSP titles in eboot format.

How to use

If you have zRIF fake license, then execute:

pkg2zip package.pkg zRIF_STRING

This will create title [id] [region].zip file. Title, ID and region is automatically detected from pkg file. It will include work.bin file.

If you don't have zRIF fake license, but just want to unpack files, then omit last argument:

pkg2zip package.pkg

Resulting zip file will not include work.bin. This is useful for patch pkg files.

To get output file name of the zip, use -l (must come before pkg file and cannot be used with -x):

pkg2zip -l package.pkg

To avoid zipping process and create individual files, use -x argument (must come before pkg file):

pkg2zip -x package.pkg [zRIF_STRING]

PSX or PSP pkg files do not require zRIF argument. It will be ignored.

For PSP files pkg2zip by default will create .ISO file. To create compressed .CSO file pass -cN argument where N is compression factor. For example, for fastest compression use:

pkg2zip -c1 package.pkg

To create smaller cso file (more compression will require more time) use -c9, or anything inbetween:

pkg2zip -c9 package.pkg

You can combine -cN argument together with -x:

pkg2zip -x -c9 package.pkg

To extract PSP files in their original EBOOT.PBP format use the '-p' argument:

pkg2zip -p package.pkg

Note: On PSP hardware titles with DLC should be kept in ISO/CSO format due to limitations on the CFW NoDRM Engine.

Generating zRIF string

If you have working NoNpDrm license file (work.bin or 6488b73b912a753a492e2714e9b38bc7.rif) you can create zRIF string with rif2zrif.py python script:

$ python rif2zrif.py path/to/work.bin

It will print zRIF string to stdout.

To generate work.bin from zRIF string use zrif2rif.py script:

$ python zrif2rif.py zRIF work.bin

Last argument is optional, it specifies where to save file and defaults to work.bin name.

Limitations

No actual title name is extracted for PSM pkg files.
