DS games on the 3DS(mock ups): A Comparison

Gaming Gauge writes:"So we recently got a look at how DS games function on the 3DS. As you can see the games are upscaled to fill the screen rather than mapped 1:1(although the option may be there). The downside to this method is that the games lose a bit a clarity, they can appear a bit blurry and fuzzy. I thought it would be interesting to make some mock up screenshots to compare how different styles are affected by the upscaling."
