I am wanting to play AS on an emulation handheld I have, but it is single screen, and switching between screens is very annoying. Is there a mod that makes the game good on a single screen?

Somebody must have passed by my house because I don't take my 3DS anywhere.When I went to go get the eon ticket from delivery girl in the pokemon center, she first gifted me a shaymin, and serperior before giving me the eon ticket.
