GZDoom Flatpak edition

Installation of game-data

• Copy any commercial iwad into the folder ~/.var/app/org.zdoom.GZDoom/.config/gzdoom/
• Optionally, configure the ~/.var/app/org.zdoom.GZDoom/.config/gzdoom/gzdoom.ini file to load other directories

Run with custom wads

Just as with the stand-alone GZDoom, you can pass commands through using the command line. If you want to play custom wads, you can add them to a sub-directory of /gzdoom/ and then you can directly access then from the terminal:

flatpak run org.zdoom.GZDoom -file ~/.var/app/org.zdoom.GZDoom/.config/gzdoom/pwads/PL2.WAD

cd ~/.var/app/org.zdoom.GZDoom/.config/gzdoom/pwads/
flatpak run org.zdoom.GZDoom -file ./PL2.WAD

Accessing files

If you want to access wads in different locations, you might have to adjust the Flatpak sandboxing permissions.

GUI

You can use Flatseal to visually manage your permissions: https://flathub.org/apps/details/com.github.tchx84.Flatseal

Terminal

You can easily do that like this:

flatpak override org.zdoom.GZDoom --filesystem=/OTHER/LOCATION/WITH/WADS --user
