no you need an action replay. but they are only 20 dollars and you can buy them at walmart

Get them from US in events
But i never got action replay code or Events
And I've got Darkrai, Shaymin, Arceus, Mew, Every ledgendry

No, I would recomend getting an action replay.

there is a glich you can use to get them but its risky and yu could loose your save data
go to a city with a long path going down in a straight line the go down on you bike
pressing down whil going dow press left and right repeatedly until you get to the bottom
of the town/city and if its done right you can enter a black/white void and you can ge to
darkrais/shaymins island without ar or events
