ResidualVM

ResidualVM is an open-source game engine project created to run certain classic adventure games on modern computers by replacing their original executable code with a compatible engine. Rather than being a conventional game itself, it acts as a bridge between old software and new operating systems, preserving titles that might otherwise become difficult to play. It is particularly interesting for fans of vintage adventures because it allows the original games, graphics, sound, and storytelling to survive beyond the hardware and operating systems for which they were designed. The idea is wonderfully practical: instead of forcing a modern computer to pretend it is an ancient machine, give the old game a new engine that understands what it is supposed to do. It may not sound glamorous, but projects like ResidualVM are quietly important pieces of gaming preservation. Sometimes the hero of retro gaming is not the knight, but the compatibility layer.
