This is a small GUI application that helps to download and play Bungie's classic Marathon games. Bungie has allowed to release the Marathon games gratis on Github but they're still under a proprietary license, making it hard to release them through a distro's packaging system.
External binaries that are expected to be in PATH are alephone, wget, xdg-open and xterm.
A custom download script can be specified through command line.
See marathon-game-launcher --help for a full list of options.
Build dependencies are: cmake xxd libpng zlib libx11 libxrender libxft libfontconfig
On Debian-based systems: apt install build-essential cmake xxd libpng-dev zlib1g-dev libx11-dev libxrender-dev libxft-dev libfontconfig-dev
Be sure to download FLTK first with ./get-fltk.sh or git clone https://github.com/fltk/fltk.
Then simply run make.
