Our friend Bertrand / Atari Frog from AtariMania.com has informed us of a new recovery they have made from some archived disks from the short-lived Atari 8-bit publisher Harlequin Software. This includes materials for abandoned conversions of Last Ninja 2, Paperboy and Robocop.

The preservation work is thanks to John Hardie (National Videogame Museum) and to Stephen Goss (Harlequin Software founder) for allowing the archival of the images. Links can be found below to the disks and artwork that has been recovered.
All artwork was produced by Robert David Swan to help secure the rights to convert the games to the Atari. It seems that the Last Ninja 2 artwork was produced after Harlequin Software had secured the rights.
