Go to spear pillar
To get the arceas flute is : (you need a action replay DS or DSi) so yo go to Canalave city(only) and go to the pokemon mart (blue top) and press L+R and you will see a guy in a green hat and he will give you it. And go to the spear pillar and use the flute and a staircase will appear and YOU WILL FIGHT the GOD OF ALL POKEMON:ARSEAS
I really don't know I have the same problem none of those answers work I've tried every spot on the spear pillar
I have a problem to.I have the azure flute (action replay way)and I wanted to know if I need the code on while I go up to the spear pilar...
As far as I know, there must be an event held at your nearest TOYS'R'US (you can check when events are held at pokemonplatinum.com) That's the only way I know of if there is to be an event held to download the Azure flute. If so, go to Spear Pillar atop Mt. Coronet, and play the Azure flute. A secret staircase should appear that takes you up above Spear Pillar where you finally encounter Arceus. Other than that, the only direct way to do this is by using an Action Replay (AR). Personally, I like catching my Legendary Pokemon legitimately. (The real and fair way)
When your at spear pillar go to the middle of the poke ball and play it there the flute maker whats his name will open a golden stair case will open and at the top you will meet the god Pokemon,whats his name
