How do you get 2 darkraies on pearl?

Answer 1

Get an Action Replay and activate the run through walls Cheat. Then go to crescent island. Now run east. In a few seconds you'll find New Moon Island. Then you find and catch Darkrai. Later, get the Member's pass from the event of cheat. Go to the lock inn in Canalave city above the Pokemon center. You will be able to go in. Once in, You'll lie in the bed. When you wake up you'll be in New Moon Island. There you'll find Darkrai a second time. Catch him. You now have two Darkrai's!
