1) I wanted to know if you could incorporate two more resolutions, one in 4:3 aspect, to take better advantage of the PSVita screen, but without distorting the proportions of the game as much as the full screen 16: 9 mode does.
2) Also another in vertical 4: 5 or 2: 3, with the image rotated to the left, therefore in TATE mode, so that the games can be controlled with the right stick and played with the square and triangle, it would made the Vita a Game Boy on steroids. This portrait mode would allow for the largest image size with little deformation (or none if 1:1).
