GNU Robbo is a free open source reimplementation of QXLand’s Robbo for the Atari XE/XL from the late 1980s. The gameplay of the original is faithfully reproduced with a few modifications.

If you’re upgrading from a previous version then please backup the .gnurobborc file (later versions use gnurobborc) before you delete the folder as this file contains your level pack progress and modified options.

Changes:

Significantly reduced the memory usage
Added localisation to the level designer
Added support for Maemo 5 Fremantle
Added preliminary support for Alex (a Robbo clone)
Added Czech translation by Radek Pavle
Fixed a few bugs and outstanding issues
Applied various graphical and usability tweaks
