ScummVM is an emulator that runs classic point and click adventure games we know and love. Games like Monkey Island 1 & 2, Beneath a Steel sky, Indiana Jones, Lure of a Tempress, Manic Mansion and Day of the Tentacle. Just to mention a few.
The latest PSP build can be found here: http://www.scummvm.org/downloads.php at the official website. Rather than offer the download directly of our server we feel its best you go to the source as ScummVM changes often and is on many other platforms. Even your Iphone!
