CpkPatcher

Tool for patching a Criware CPK archive by updating file data without repacking the entire CPK.

Features

Loads and patches a CPK with files from a patch directory.
Any files existing in the CPK that are not found in the patch directory will remain unmodified. Any unpatched files that had compression will remain compressed.
Supports patching nested CPKs with --check-for-nested. Any folder which exists in the main CPK as a CPK will be loaded and patched.

Example:

For the following CPK structure
```
.
└── main.cpk/
    ├── file1
    └── sub.cpk/
        └── file2
```
A patch directory for patching file1 and file2 should look like this
```
.
└── <patch_directory>/
    ├── file1
    └── sub/
        └── file2
```

Usage

Full help message:

CpkPatcher v1.0
Patches a CPK by updating file data without repacking the entire CPK

Positional arguments:
  source_cpk              Path to the source cpk
  patch_directory         Path to the directory containing the patch files
  output_cpk              Path where the output cpk will be written

Optional arguments:
  -h, --help              shows help message and exits
  -v, --version           prints version information and exits
  -rp, --report-progress  Print a message after patching each file
  -re, --report-errors    Print a message when a file could not be patched
  -n, --check-for-nested  Check for nested CPKs while patching and patch them accordingly
  -ow, --overwrite        Overwrite output CPK if it exists without prompting

Limitations

Does not compress patched files, although unpatched files that were previously compressed will remain compressed.

Has the same limitations as the CPK implementation. Mainly, files with a GToc table are not supported.
