All you need is a action replay.Go to Fullmoon Island run to the right on water and on the island should be a entrance go in there and there is darkrai
get the members card and go into the house with the locked door
you cant. it is a special event that has already passed in Pokemon diamond. the item you have to get is the darkrai pass and then the door opens you fall asleep in the bed then you go into a dream where you find darkrai he is lv 70 hope this helps
Get the key from Mystery Gift and open the door in caveport that is locked.
== == That house actually is part of the way to get darkrai. You get the item that opens the door via mystery gift. == == == ==
You get it with special event or you go to New-moon island.um you need the cheat code thing =] its like, you buy the cheat codes and you set it and choose darkrai. then you go to the hotel with the locked door you'll be able to go in.
If you mean the harbor door the event is the Darkrai event! It has been distributed previously but you can have it from a friend that has it!
To get into the Harbor Inn in Pokemon Diamond and Pearl. Is when you get to the point you have walked... 999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999 steps. You go to the house with the sleeping boy inside. Go to Newmoon Island. Find Darkrai. Catch! Hooray. Hope this helped.
You have to get the members pass in a Pokemon wi-fi event, then go to canlave city with the locked door and go to the bed and and you will appear at new moon island and DARKRAI is there so save in front of darkai and try to catch it ( Darkrai will be at lv 40 or lv 50 )
upstairs in the Pokemon center first door
you need the darkrai event item. go 2 supercheats.com-some1 should have the event item for action replay(of course, if you don't have an action replay, oct. 24 there is an event...I THINK
The inn's sole purpose is to allow the player to receive the event pokémon Darkrai. Other than attending the official Nintendo event to receive the mystery gift, you can use a cheat device such as Action Replay to give you the Membership/Member's Card, which should open the door and allow you to capture Darkrai.
you find him next to the door in the thropy garden
