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 game, allowing you to play them on systems for which they were never designed!
Note: Scummvm runs in landscape mode and due to the bug http://docs.openmoko.org/trac/ticket/1244 it is not yet usable.
The games are copyrighted so you'll only be able to play those you own. You can also download some free games.
When starting ScummVM use the command
This will map AUX button to the F5 key, which is used to access the ScummVM menu. You should also find an entry on the main menu under Games.
More information on ScummVM can be found on the official site
Monkey Island 2
To be able to play Monkey Island 2 you need to pass ScummVM a parameter:
root@fic-gta01:/$ openmoko-scummvm --boot-param=10001 monkey2
For easy access from the menu you can create a menu entry by creating the file /usr/share/applications/monkeyisland2.desktop with the following content:
