    This script isn't needed anymore as Blacksmith works as intended after installing urlmon and wininet to the prefix with winetricks. It will be left up as an alternative/in case of future breakages.
Requires:

Python 3
requests

Usage (install) untested:

Install the Blacksmith launcher through Lutris or other means
Navigate to your IRONMACE folder (e.g. ~/Games/dark-and-darker/drive_c/Program Files/IRONMACE)
mkdir "Dark and Darker"
Continue to update instructions

Usage (update):

Save dnd_linux_patcher.py
Navigate to your Dark and Darker folder (e.g. ~/Games/dark-and-darker/drive_c/Program Files/IRONMACE/Dark and Darker)
python path/to/dnd_linux_patcher.py

This attempts to at least partially emulate Blacksmith's patching by:

Getting current file hashes from Dark and Darker's CDN
Calculating SHA256 hashes of your existing files
Comparing those hashes
Downloading any files with hashes that don't match

This is a quick, personal script. It has worked as intended for me, but use at your own risk. Ensure no changes are needed for your setup and that you've read and followed the instructions properly before use.
