I am getting my PSP slim modded soon via pandora battery.

I just played God of War a little on the PSP and it was very tiny, I know, what did I expect, but this problem made me wonder about how the FF games will play. Is it an issue that they will be on the tiny screen?

I played the FF advance games on DS, and I never had a problem with their small size, but FF7,8,9 are 3D games, so maybe it won't look good?

Finally, do the FF7,8,9 games on PSP slim stretch out to take the whole screen or will it be 'full screen'? Is there a way to change it?

Do the games run smoothly?
