Couldn't find this on here already so apologies if it already is.
I am still in shock that ScummVM works on my Android 2.1 tablet and I am now able to play the likes of Monkey Island 1&2, Loom, Zak Mckraken and all my favourite point and click adventures.
What is it?
"ScummVM is a program which allows you to run certain classic graphical point-and-click adventure 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!"
Better still some of the games companies have officially released freeware versions of their games such as beneath a steel sky and Lure of the Temptress.
Control system takes a little getting used to but well worth it
I know these games aren't up with the modern day games but they rocked when I was 9 and their still good now IMO .

Now to see if I can find a port of MFME or MAME.
