The lilliput should have an additional composite video input.
All you do is switch inputs on the screen to whichever the PS2 is plugged into and game on.
so i understand the whole concept of installing the mini along with a lilliput touch, i've read a little on here. but what i was wondering is if there is anyone who has or knows how to install a ps2 so that it will run off that same lilliput?? like some kind of switch of something?
yep yep, see above. I have an xbox in my car.
