Feature Request: Vertical Crop

[KremlingKuthroat19]

This is an absolutely brilliant core! Kudos to Flandango and everyone else involved. Every game I tried works so far.

The only feature request I have is to have a vertical crop option (i.e. Vertical Crop: 216p(5x)) that's found in the other console and computer cores. There's a lot of border space and it'd be a neat feature to be able to zoom in on the games and remove some of that border space.
