i think having an option would be the best.
psp's aspect ratio is close to 16:9 (for complete 16:9 it'd have to be 483x272 rather than 480x272), so it'd look just fine if fully stretched on my screen (it'd probably end as 1920x1088 so the 8 pixels would have to be squished), but would look pretty bad on different aspect ratios.
