This is crap! None of the options fill the screen perfectly vertically? This is the stupidest thing ever! You can have a half inch cut off the top and bottom, or stretch it a little vertically and screw up the aspect ratio or zoom in and cut a lot of the image off. Why in the world is there no option to fill the screen vertically while maintaining the correct aspect ratio? Whoever thought this was ok should be fired and sterilized. lets not take advantage of this nice screen at all.
You can't fill the screen vertically while maintaining the aspect ratio because these games have a native aspect ratio of 4:3. They were made before widescreen displays were commonplace. The only way the Vita could display these games and fill the screen would be to have a large square screen or reprogram all the games. Neither are going to happen.
