Robbo: 3 Open Source Clones Compared
PyRobbo is built with PyGame and reuses graphics and level data from the free, open-source gnurobbo project rather than the original Atari XE/XL game's own assets, and is licensed under GPL-3.0. The robbo project is instead a JavaScript implementation that runs directly in a browser by opening game.html, with no build step required, released under the MPL-2.0 license.
