Flatpak for DOSBox

Installation

This Flatpak is available on Flathub. After following the Flatpak setup guide, you can install it by entering the following command in a terminal:

flatpak install flathub com.dosbox.DOSBox -y

Once the Flatpak is installed, you can run DOSBox using your desktop environment's application launcher or by running flatpak run com.dosbox.DOSBox in a terminal.

Updating

This Flatpak follows the latest stable DOSBox version. To update it, run the following command in a terminal:

flatpak update

Limitations

For security reasons, this Flatpak is sandboxed and only has access to the user's Documents folder. You should place any files you need within DOSBox in that folder (or in a subfolder).

Please create an issue if you find any other limitations that should be documented here.

Configuration files

Under the default Flatpak configuration, the DOSBox configuration files are located in ~/.var/app/com.dosbox.DOSBox/.dosbox/. To access it with a graphical file manager, you'll have to make hidden folders visible.

Building from source

Install Git, follow the flatpak-builder setup guide then enter the following commands in a terminal:

git clone --recursive https://github.com/flathub/com.dosbox.DOSBox.git
cd com.dosbox.DOSBox
flatpak install flathub org.freedesktop.Sdk//22.08 -y
flatpak-builder --force-clean --install --user -y builddir com.dosbox.DOSBox.json

If all goes well, the Flatpak will be installed after building. You can then run it using your desktop environment's application launcher.

You can speed up incremental builds by installing ccache and specifying --ccache in the flatpak-builder command line (before builddir).
