Having played it previously, in a remastered state, for PS3, I have found this port to also be of superior quality

Thus, playing it on the PS TV I would recommend that the resolution be set to 1080i as this would guarantee a better visuals and audio quality of the game.

(and sure it doesn't look as good as on the PS3) but you have to give credit to the fact that you're playing a game originally made for the PS2 on a portable device, it's not going to be absolutely perfect
