How do you get an Arceus in platinum?

Answer 1

There are two ways known so far-

1-get the azure Flute by cheating with action replay IN POKEMON DAIMOND OR PEARL, then go to spear pillar,(in the daimond/pearl game you cheated. There is an about 70% chance you'll destroy your game if you cheat platinum) use the azure flute as soon as you get in, and a golden staircase will appear. Arceus is at the top. if you can catch it, use a friends D.S to trade arceus to platinum. of course, you can always trade with an actual friend to get arceus. I have 3,one on platinum, and two on daimond. one I got from a friend and the others from the method below-

2- GameStop locations or TRU(toys r us) stores may send you a mystery gift which could be an arceus or an azure flute. Right now(february 4, 2010) there is a shiny speicial pichu available at gamestop(ending february 14th,2010) through this method. Check pokemon.com or the actual stores for more info.

Note-the arceus event passed from TRU a while ago. either it will happen again an gamestop, or an azure flute will be available.

Pokemon Heartgold or Soulsilver versions may have a way to get arceus. mabie if you trade with those games you can get one!

(the shiny pichu is meant to trade into heartgold or soulsilver to catch a spiky eared pichu in those games at ilex forest. THE Arceus from the event was also meant for the ability to capture a Giritina Dialga and Palkia)
