ScummVM stands for Script Creation Utility for Maniac Mansion Virtual Machine. What this little beast does is that it acts as a Virtual Machine for these games. So finaly you can get into these games again, and it doesn't matter if you have the MS-DOS, Apple Macintosh, Commodore Amiga or Atari TOS versions of the games, all will work. If you don't have any of these games you can find some demos here, and the Public Domaine games here. Oh, and did I mension that ScummVM is available for a multitude of platforms: Amiga OS 4, BeOS (and presumably it should run on Haiku OS), Mac OS X, Windows a host of Linux flavours and many more (most notably SEGA DreamCast, Nintendo DS and Sony PSP).
This is a lot of fun and I whole heartedly recommend this. I hope you to find that these old games are still very good, and a lot of fun.
---Happy Gaming---
