Backwards Compatibility: A Short Guide to Playing DS Games on the Nintendo 3DS

DS games receive no visual enhancement when played in a 3DS. The resolution is not increased and they are not magically converted to 3D. But because there is the difference in resolution for the top screen of the 3DS compared to previous handhelds, borders are added to that display. There’s no difference with the bottom screen. Apparently there is some sort of blur filter applied to DS games when played in the 3DS. I feel ignorant for saying this, but I’m not sure of this filter’s purpose, although it doesn’t sound like it’ll be too annoying
