scummvm

Script Creation Utility for Maniac Mansion Virtual Machine (ScummVM) is a set of game engine recreations. Originally designed to play LucasArts adventure games that use the SCUMM system, it also supports a variety of non-SCUMM games by companies like Revolution Software and Adventure Soft. It was originally written by Ludvig Strigeus. ScummVM is free software that is released under the terms of the GNU General Public License.
ScummVM is a re-implementation of the part of the software used to interpret the scripting languages such games used to describe the game world rather than emulating the hardware the games ran on; as such, ScummVM allows the games it supports to be played on platforms other than those for which they were originally released with little or no overhead (due to not emulating the hardware), and without the bugs that might exist in the original software.
The team behind it also add improvements such as bug-fixes and translations and works with commercial companies such as GOG.com about re-releases.
