A module for applying fixes at runtime to unsupported games with Steam Proton without changing game installation files. The idea is to include seperate fixes that are only loaded when a game matching that ID is run. This should keep the individual game fixes from affecting any other games. Applying the fixes at runtime should also get them to persist after game updates.
A list of current fixes, guide for writing game fixes, and details on game fix utilities can be found on the Wiki. Sources for gamefixes can be found in the protonfixes/gamefixes directory.
Winetricks
If you want to be able to use fixes with winetricks it must be installed and be in your $PATH. Fixes that do not use winetricks will still work without winetricks being installed.
Winetricks can take a long time to run
Wine
If you want to use a win32 (32bit) prefix, you need to have wine installed and be in your $PATH. Currently creating a 32bit prefix with Proton wine doesn't work because the wineserver is already running by the time user_settings.py is loaded.
Progress Dialog / Splashscreen
If Steam is in big picture mode, protonfixes will try to launch a similarly themed splash dialog using cefpython (pictured above). Otherwise it will try to use zenity to display a progress bar. If Steam is not in big picture mode, it will default to zenity. The progress bar or splashscreen can help let you know that protonfixes is running a long task, for example installing dotnet35.
For the progress dialog to work, you need to have zenity installed on your system, the steam-runtime version is broken. It can probably be installed using your distro's package manager.
For the big screen splashscreen to work, you need to have cefpython3 installed. It can be installed with pip using sudo pip install cefpython3.
Make sure to use the version of pip that matches the version of Python that Proton is running. Proton should be running on python3. If you are unsure, try installing with both pip3 and pip2 in the below commands.
# sudo pip3 install protonfixes
To install the latest version from Github:
# sudo pip3 install git+https://github.com/simons-public/protonfixes@master
To upgrade to the latest version on Pypi:
# sudo pip3 install protonfixes --upgrade
To upgrade to the latest version on Github:
# sudo pip3 install --upgrade git+https://github.com/simons-public/protonfixes@master
# sudo python3 setup.py install
In the steamapps/common/Proton* directory, add the following line to the bottom of the user_settings.py file:
import protonfixes
If there is no user_settings.py file, make a copy of the user_settings.sample.py file included with Proton.
