The only way for you to do that is to use an Action Replay, and use the Walk/Run anywhere cheat. I would suggest going to Iron Island or somewhere close to Newmoon Island where Darkrai lives. He is level 50, and good luck.
use an action replay or r4 or anything that enables you to walk through anything. then goto the place where you meet cresselia and keep walking right. the you'll find and island go to the entrance, then battle darkrai!
You needed a Nintendo Event to get an item to trigger an event to catch him, but this is unlikely to return.
get a darkrai from your friend[note if they want to trade)

You can't get Darkrai in any Pokemon game without cheating or hacking.

YoU can't, sorry
You can't unless you hack it into your game 'cause there's no other way to get Darkrai without its special item or without Nintendo giving out an event Darkrai.
You can't get Darkrai in any Pokemon game without cheating or hacking until they make an event for it.
The only way to get a darkrai is for an event, i dont have one because i didn't have the game when it was on, you can get it without an event with action replay.
it is darkrai or garatina but i do have arceus but you have to cheat to do it hope it helped on i have no idea
You get the membership card in the Canalave City Pokemon market and you go to the house where is locked and it won't open. Then you go to the sailor and you keep talking to him until he say to go to the house that is locked and it will open then the guy with the sun glass will take you to the bed and you well dream a nightmare and you will go to the island where is Darkrai. Then you can catch Darkrai. Please correct me if I am wrong.
