This utility is designed to accurately manipulate the EHP/EhFolder archives found in the PSP Yu-Gi-Oh! Tag Force games.

Currently command line only.

• Extraction of EHP to folder with correct filenames and sizes
• Packing of a folder back to EHP fully compatible with the game

This tool should be 100% compatible with the official EhFolder specification and any Tag Force game.

Extracting: ehppack InFileName [OutFolder]

Packing: ehppack -p InFolder [OutFileName]

If the optional (in []) parameter isn't specified, it'll reuse the input name.

You may also drag and drop an EHP to the binary to extract a file if you're on a supported OS.

You may also install this in the Windows' context menu by using the install script.

Simply do the following:

• Put install.bat and install.ps1 next to ehppack.exe

• Run install.bat as Administrator once (or run install.ps1 directly with the Bypass ExecutionPolicy)

In case you have UAC virtualization enabled, you may run into issues. Please run install-noreg.bat in that case instead and import the ehppack_context.reg key manually (usually by double clicking on it).

You may need to log out and back in for it to work properly.

The context menu will appear for all .ehp files (for unpacking) and all directories (for packing).

The install script installs the binary into %APPDATA%\ehppack and adds it to your user's PATH.

Running as Administrator is necessary to write in these registry keys (and subkeys inside):

HKEY_CURRENT_USER\Software\Classes\.ehp\shell\ehppack

HKEY_CURRENT_USER\Software\Classes\Directory\shell\ehppack

Use the standard CMake building procedure:

$ mkdir bin
$ cd bin
$ cmake ..
$ cmake --build .

And to install, just do: # cmake --install .
