ScummVM is a program which allows you to run certain classic graphical point-and-click adventure games, provided you already have their data files. The clever part about this: ScummVM just replaces the executables shipped with the game, allowing you to play them on systems for which they were never designed!
Some of the adventures ScummVM supports include Adventure Softs Simon the Sorcerer 1 and 2; Revolutions Beneath A Steel Sky, Broken Sword 1 and Broken Sword 2; Flight of the Amazon Queen; Wyrmkeeps Inherit the Earth; Coktel Visions Gobliiins; Westwood Studios The Legend of Kyrandia and games based on LucasArts SCUMM (Script Creation Utility for Maniac Mansion) system such as Monkey Island, Day of the Tentacle, Sam and Max and more. You can find a thorough list with details on which games are supported and how well on the compatibility page. ScummVM is continually improving, so check back often.
Among the systems on which you can play those games are Windows, Linux, Mac OS X, Dreamcast, PocketPC, PalmOS, AmigaOS, BeOS, OS/2, PSP, PS2, SymbianOS/EPOC, iPhone and many more.
At this time ScummVM should be considered beta software, and is still under heavy development. Be aware that whilst we attempt to make sure that many games can be completed with few major bugs, crashes can happen.
