3.5" screens with s-video input?


I like purpale ponies
I need one for my portable n64 and I need it small!(psone screen would be too tight a fit and would be really awkward) s-video is outputted on all n64s while rbg is not, and s-video is next best to rgb(or is it the other way around?) All I know is that I need a good 3.5" s-video screen link, any help would be totally appreciated.(most are composite, aren't they?) btw what resolution is the psone screen?(don't slap me with a wet, cold blooded penguin for asking both questions)
nvm, I'll just use a dealextreme screen.
