Developed as an open-source project, ScummVM aimes to create a cross-platform game interpreter that would enable classic adventure games to run on modern systems, including AmigaOS. The project’s genius lay in its ability to interpret the scripts and data files of these games, effectively creating a virtual environment in which the classics could be enjoyed once again. The clever part about this is that ScummVM just replaces the executable shipped with the games, allowing you to play them on systems for which they were never designed. Work on ScummVM started in September 2001 by Ludvig Strigeus. Looking to write his own adventure game, he looked to see how the mechanics of an existing game engine, specifically working to create an emulator to play Monkey Island 2. ScummVM continues to add new games or game engines and ScummVM has been a participant in the Google Summer of Code every year since 2007. The new optimized release of ScummVM (version 2.7.1) for AmigaOS classic offers several improvements and fixes.
