ScummVM supports an extensive library of over 325 adventure games, including classic titles from iconic studios such as LucasArts, Sierra On-Line, Revolution Software, Cyan, Inc. The clever part about this: ScummVM just replaces the executables shipped with the games, allowing you to play them on systems for which they were never designed! ScummVM is a complete rewrite of these games' executables and is not an emulator. ScummVM is a program which allows you to run certain classic graphical adventure and role-playing games, provided you already have their data files.
