What does is_new_3ds=false in qt config do?

It doesn’t do much right now, but if you set it to true, you can play the New 3DS exclusives, such as Xenoblade Chronicles 3D.

its there for the few functions citra has implemented to tell the game its running on a n3ds. thing is, games don’t usually use those functions, they use other methods like checking for extra circle pad and stuff. So honestly the option is pretty useless right now, but may be more useful in the future
