PC Building Simulator

PC Building Simulator requires DXVK, Wine-GE, and some fonts

Download the latest version of Wine-GE and extract it to somewhere you can remember (I prefer ~/Wine/Versions/Wine-GE).
Create a folder somewhere you can remember, this'll be your Wineprefix (small virtual Windows environment) (I prefer ~/Wine/Prefixes/pc-building-simulator.

Open a Terminal and run export WINEPREFIX=/path/to/wineprefix (replacing the path of course; make sure there's no / at the end).
Then run export PATH=/path/to/Wine-GE/bin/:$PATH (again replacing the path; make sure you keep the /bin/ at the end).
With that in place, wine --version should now have GE somewhere in the version string (currently 6.18-GE-1 (Staging)).

Run wineboot -i && wineserver -w. This will setup the previously mentioned virtual Windows environment in the folder you chose.
After this, you can install DXVK.

Alright, one last step in the terminal and you're done with that. This one's an easy one too: Run/copy-paste the following commands:

cd $WINEPREFIX/drive_c/windows/Fonts
curl -L https://github.com/CommandMC/EpicLinux/raw/main/arial/Arial.zip -o Arial.zip
unzip Arial.zip
rm Arial.zip

Now, as a last step, we have to tell Legendary about the configuration changes we made. For that, open up the config.ini file in ~/.config/legendary/ and add the following (again replacing paths, you get the idea):

[ab277c0995e945d2b2c50c46883627f1]
wine_executable = /path/to/Wine-GE/bin/wine
wine_prefix = /path/to/wineprefix

And finally, you can launch the game. Have fun building PCs!
