ScummVM

ScummVM is an emulator for a range of classic 'point-and-click' adventure games. It supports games based on the SCUMM engine (originally created by LucasArts). This includes classics like Monkey Island, Sam 'n Max and the Day of the Tentacle. But there are many more.

The original game data is needed to play these games. Several of the supported games have been made open source, so can be played for free. These can also be downloaded at the ScummVM homepage.

Currently free game data available for:
 * Beneath a Steel Sky
 * Flight of the Amazon Queen
