A Python script that allows for extracting and packing Persona 3's CPK files.
Requires Python 3.2+ (determined using vermin.)
To unpack a single .CPK file:
python p3cpk.py -i "path\to\file"
To unpack all .CPK files in a folder:
python p3cpk.py -f "folder\path" [-u|--unpack]
To pack a folder into a .CPK file:
python p3cpk.py -f "folder\path" [-p|--pack]
To convert a single .CPK file into a .PAC file:
python p3cpk.py -i "path\to\file" [-c|--convert]
To convert all .CPK files in a folder into .PAC files:
python p3cpk.py -f "folder\path" [-c|--convert]
You can optionally specify a folder to output extracted or packed files to, like so:
python p3cpk.py [-i "file"|-f "folder"] [-u|-p] [-o|--output] "output\folder"
Other available arguments can be seen by running the script with only the help argument:
python p3cpk.py -h
When unpacking CPK files, the script will create a Config.json in the folder of the unpacked CPK. This file contains some settings which determines how exactly the script will re-pack that CPK. The settings are as follows:
| Setting Name | Data Type | Description |
|---|---|---|
| NoNullHeader | Bool | Determines whether or not a "null header" should be appended to the end of the CPK. For information on null headers, see DOCUMENTATION.MD. |
| SkipExtraData | Bool | Determines whether to load file padding/extra data from the files in the "(CPKName)\ExtraData" directory or to generate the required file padding. |
| AutomaticImport | Bool | Determines whether or not the script should pack all files contained within "(CPKName)\Files" or if it should only pack manually defined files. |
| Files | String Array | A list of all files contained within the CPK. When AutomaticImport is set to false, this list is used to manually define which files in "(CPKName)\Files" will be packed into a CPK. |
