No, you have to fly a way if you hang on a second I'll edit this post with a hint.
"1) Fly away from whoever and go to a PC.
2) Press your A button in front of th PC and it should turn on (it does). Then go to "Change Box."
3) Change your Box and then turn off your game (turn it back on).
4) Your A button should work. This way you can use Gym Leaders for the cheat, if you haven't already beat them."
-Me This way you can even battle Gym leaders and the Elite Four. Also use the Ditto encounterance to get anything.
