ScummVM

ScummVM is a program which allows you to run certain classic graphical point-and-click adventure games and role-playing games, provided you already have their data files. 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 supports a huge library of adventures with over 250 games in total. It supports many classics published by legendary studios like LucasArts, Sierra On-Line,
