Using ScummVM on the PS2 is very similar to using it on a normal computer, the biggest problem is that you must find a way of booting homebrew on your PS2. There are many ways of booting homebrew on a PS2 - FMCB, modchip, swap magic, hdloader, etc. If you don't currently have a method of using homebrew, search for FMCB (Free Memory Card Boot), you'll even find people who will install it for free on your MC. Nearly all PS2s can use FMCB.
ScummVM can be run in many ways e.g. from USB, HDD, MC, CD, DVD and network. Probably the easiest way is from USB with FMCB, so I'll describe that:-
Download the PS2 version from http://www.scummvm.org/downloads/
Make a folder on your USB device e.g. "ScummVM", unpack the PS2 files in that folder
Make a folder for your games as well e.g. "ScummVM_Games", make a subfolder for whatever game e.g. "Monkey1", copy the required files from your CD/DVDs to the subfolder. Check what's required at http://wiki.scummvm.org/index.php/Datafiles
When the console has booted up, run UlaunchELF, browse files, goto mass:, find the folder you made earlier, run SCUMMVM.ELF, configure ScummVM as you would on a computer, play game.
ScummVM Ps2 saves and loads fine, for more info have a read of the documents included with ScummVM PS2.
