simple question of anti-aliasing

[AcidRains]

Have a little question about this anti-aliasing so i'm asking here, so far i've been using jpcsp on window screen so never play it on fullscreen mode. So is this anti-alias only function with fullscreen mode? because if try to play around with the setting but seems make no change of ingame graphic, or is it broken already? thanks for any reply
