Getting Darkrai and Cresselia
This cheat will show you how to get Darkrai and Cresselia
After you beat the Elite Four. Go to Canalave City and go to the house located on top of the sailer. Go in the house and there should be a mom and a boy. Talk to both of them and the sailer is supposed to come in. When the sailer finished talking, go out and talk to him. Go to Fullmoon Island. When your there you will be able to get Cresselia.
After you capture Cresselia the house with the locked door will be unlocked! The guy in the house will say he has been waiting for you. Sleep in the bed and you will get transported to new moon island and darkrai will be waiting there. I suggest you save before you start battling.
