So the game can't render a bigger image, but they are fine to render at a lower resolutions. And most games do so.
So a common viewport is 640x480 to match the aspect of the output. And the remaining 48 pixels are available for small offscreen renderings without saving the framebuffer at all (me looks at NSMBW).
