ScummVM is an interpreter that allows you to play many point and click adventure games from the 80s and 90s on modern computers. I didn’t write ScummVM, that honour goes to the ScummVM team. ScummVM runs games from Lucasarts that were created using the SCUMM system (hence the name) but it has also been expanded to run games from many other developers too. ScummVM is written in portable C++ and has been ported to many differnet platforms, and I have made a port of it to the DS. This means that you can play all these classic games on the DS with full sound.

Changes:

New engines supported: AGI, CINE, and SAGA.
Option to show the mouse cursor
Word completion on keyboard for AGI games
Plenty of optimisations
Numerous bug fixes
