I made this topic to have people discuss what they think about playing ordinary ds games on the 3DS. Some people say it's really blurry but I think it's just fine. I've been playing Super Mario 64 DS on my 3DS because I wanted to play it with a joystick and it works very well. As far as I know, nothing is negatively affected in the game itself. If you hold select, you can play the game without any blurriness. However, it makes both screens very small and that is a huge distraction to me.
