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.

User guide

Requirements

How to use

Use the following command if you have zRIF fake license.
This will create title [id] [region].zip file. Title, ID and region is automatically detected from pkg file. It will include work.bin file. Example: 

pkg2zip package.pkg zRIF_STRING

Omit last argument if you don't have zRIF fake license, but just want to unpack files.
Resulting zip file will not include work.bin. This is useful for patch pkg files. Example: 

pkg2zip package.pkg

Use -l to get output file name of the zip (must come before pkg file and cannot be used with -x). Example: 

pkg2zip -l package.pkg

Use -x argument to avoid zipping process and create individual files (must come before pkg file).
PSX or PSP pkg files do not require zRIF argument. It will be ignored. Example: 

pkg2zip -x package.pkg [zRIF_STRING]

For PSP files pkg2zip by default will create .ISO file.
To create compressed .CSO file pass -cN argument where N is compression factor (1 for the fastest compression). Example: 

pkg2zip -c1 package.pkg

Use -c9, or anything inbetween to create smaller cso file (more compression will require more time). Example: 

pkg2zip -c9 package.pkg

You can combine -cN argument together with -x. Example: 

pkg2zip -x -c9 package.pkg

Use the -p argument to extract PSP files in their original EBOOT.PBP format. Example: 

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.
Example (it will print zRIF string to stdout): 

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

To generate work.bin from zRIF string use zrif2rif.py script.
Example (last argument is optional, it specifies where to save file and defaults to work.bin name): 

$ python zrif2rif.py zRIF work.bin

Limitations

No actual title name is extracted for PSM pkg files.
