Believe its the VRAM / chipset limit, quite high resolution / refresh for Classics.

As far as I remembet the video chip used does 130 MHz @ 8bit and 85 @ 16bit, so that's the maximum (without using the 10 MHz overclock which may degrade the picture). But I don't remember with which chips the overclock tooltype works.
