Tools to extract assets from Myth: The Fallen Lords (TFL) and Myth II: Soulblighter (SB) tag files.
These are the currently included scripts, please file an issue if you have ideas for any more.
This is a replacement for UnTag among others.
List and export tag files from TFL or SB monolithic tag containers (e.g. artsound.gor or international large install).
Usage: python3 mono2tag.py <mono_file> [<type> <id> [<output_file>]]
mono_file: path to monolithic tag containertypeANDid: optional — must be provided together to export a specific tag. If omitted, just list all tags without exportoutput_file: optional — defaults to./tags/[game_ver]-[tagid]
This is a replacement for Soundblighter among others.
Exports AIFC (AIFF-C, compressed sound file format) from TFL or SB soun tag files. Note that sound tags can contain multiple permutations. Each permutation is exported as a separate file.
Usage: python3 tag2aifc.py <input_file> [<output_file>]

The goal for this project is to provide tools that are designed to be self contained and run on all architectures for many years to come without dependencies or the need for a build step.
Written in python (a readable and widely used programming language) and open sourced under an MIT license to make it easy to learn from and adapt without restrictions.
There have been tools like this before but they historically become incompatible with modern hardware, and with no source code available, are effectively lost to time.
Initially developed with python 3.13.1 on macOS Sequoia 15.2. Please file an issue if it doesn't work on your platform.
These tools were developed without access to the Myth source code. Some useful information was found in the source code for Chaos by TarousZars. Further information thanks to Project Magma and Oak developers.
Mostly just figuring things out with HexFiend.
- hexfiend_templates/ — Basic Binary Templates for HexFiend (macOS) that parse the top level TFL and SB tag header (doesn't show tag specific headers yet). Copy these to
~/Library/Application Support/com.ridiculousfish.HexFiend/Templates
