Ph0x released an updated port of “ScummVM”. ScummVM is an implementation of LucasArts S.C.U.M.M. (Script Creation Utility for Maniac Mansion) interpreter, used in games such as Monkey Island, Indiana Jones, Day Of The Tentacle, Sam and Max, and many more.

(NOTE!) Ph0x, nor me (Kojote) can support you with any games since they are copyrighted. This is only an engine to play those games. You have to own the original files. Details on how to use it can be found in the textfile enclosed with the ZIP-file on Ph0x’s page.
