Getting the files for Games

You can get the files needed to install Games directly from https://wiki.gnome.org/Apps/Games/Download. You’ll need to download gnome-games-3.18.0.tar.gz as well as the required libraries retro-gobject-0.4.tar.gz and retro-gtk-0.4-fixed.tar.gz. It also lists a number of recommended plugins to make it work with emulators, such as retro-plugins-game-boy-0.4.tar.gz.
