aspect ratio problem

[Cavencruiser]

Is it possible for you to add an option for corrected aspect ratio on sprites, not only to correct the squashed shape of everything but also extend the viewing field to take advantage of the gba's wider screen instead of rendering the pixels 1:1?

I have a feeling it involve multiplying the height with a decimal value, which would might add an unnecessary strain on the already weak CPU doing that to every sprite drawn to be honest.
