Here's what I do with Dodi an FitGirl repacks:
- Install
wine
, its dependencies, and Steam. I use Fedora, so I installed Steam using rpm-fusion's non-free repository. - Double click on the installer and install the game normally in a folder.
- Launch Steam and add a non-steam game. I select the .exe file used to launch the game.
- Right-click on the non-steam game and change its preferences to use Proton.
- Launch the game.
