yes
Only by trading with someone who already has it.
umm... you have to use either an action replay or you have to get a trade from a kid that got a movie darkrai.. which the event has only happened in Japan so far... but they might come out with one in the U.S. and maybe Canada.... still deciding... They have had a event for darkrai!!!!!!!!!!!! I'm not sure when it was but they usually have them all the time a Toys R us!!! I'm not sure if they have anywhere else!! But they have already had one for Darkrai!!! For Diamond I'm and Pearl but I'm not sure about platinum yet!!! You can get a schedule on pokemon.com!!!
if you used walk through walls you probably did it wrong if u did the event code and still not there...... your screwed
you have to do the purple event you can still do the purple event as blue then do the blue event
maybe you can find someone on the gts to trade for another legendary i can't because i still can't catch it.
the event is over but you used to be able to get the members card which allows you to catch darkrai you can still get the members card with action replay
Just go back and activate it. Heart Events must be gotten in order (Black, Purple, Blue, and finally Yellow). If you do not complete the Heart Event you missed you can't do any others. You do not have to lower her Heart Color back down. Even if you have a higher Heart Color than necessary the event will still work.
Yes, you can still have cramps.
Make sure you've started the event by talking to the family with the little boy who is having bad dreams. Sometimes (if you got the card through a cheat for instance), you have to backtrack and do a couple of things to get the whole event started.
you cant do the event but you still can get it
Yes, if you catch Cresselia before you find Darkrai that's fine. To find Darkrai, you need action replay. That will help you walk on water. Go to Full Moon Island and walk off the side. It will say Mystery Zone but keep walking. Soon you will reach a little island, it will say New Moon Island. There is a little grove of trees, go into it just like you caught Cresselia. Now you should see a big puddle of water and in the middle, a weird black like Pokémon. This Pokémon is Darkrai. You could always use the Jubilife City tweaking glitch to get Darkrai without Action Replay though or you could wait for the Nintendo event which will either give out Darkrai itself or the Member's Card.
yes if you have the sword of nulgath u get a quest called "not a quest" and it will make it drop-able.
