I uploaded three videos to youtube comparing the graphics with and without enhancements. First one is Genesis/Mega Drive: Normal pixelated look vs smoothened sprites, second is SNES: again normal vs smoothened sprites, and finally PSX, normal vs toon vs smooth. For the last one, I had help from a racketboy post about enhancing PSX graphics. So thanks for that.

Note: The videos were captured at 480p, so even the enhanced ones will look blurry if watched in fullscreen. But they are not blurry when I play those games, they are truly a sight to behold.
