Try using this action replay code: Click L+R then one of the following codes: 94000130 FCFF0000 62101D40 00000000 B2101D40 00000000 0000B5D4 0000000A 0000B5D8 00000000 D2000000 00000000 Two years ago there was an event called Darkrai, but it is unknown at this time if this event or another one like it will occur. During the event it was possible to pick up the flute without action replay. If you have action replay purchased you can go to the www.gamewinners.com site to chose the Azure Flute. Another method would be to seek out a friend who also plays the game and see if they are willing to trade the flute with you. Gamestop and other game locales may sell you a walkthrough guide and cheat codes that could lead to other answers for how to get the azure flute in Pokemon platinum. You will need to have WiFi in order to make a trade successful since you will need to be logged in with other players at the time. Make certain you have something the other person will be willing to trade if it is not a friend willing to hand it over for nothing. Occasionally the game hosts also use mystery gift options in the games to allow you to pick up items you want. This may or may not be available in the US, but it has been announced in the UK. Whether the mystery gift option is still available is also unknown at this time. Gamefaqs.com is a walkthrough site that offers cheats and codes. You may be able to find the answer here by looking through the walkthrough, but according to our information the event that has ended two years ago was the best way.
There is a guy on the 3rd floor of Jubilife TV and Tell him Everyone Happy Mystery Gift. Then you will get an option on the main menu called get mystery gift. Do it via wireless by a wii. You'll need Battle Revolution and beat it and get surfing pikachu and download it and you'll get the azure flute at a pokemart from a green suited guy.
You get the azure flute by mystery gift (wifi connection) then you go to any poke-mart and you will see a man with green clothes. Then he will give you the azure flute. Then you go to the spear pillar and play the the azure flute then you will see stairs. You climb the stairs. Then you will see Arceus. Warning you might need a master ball
Trade lvl99 magmortar from perl to diamond then put in daycare then it will have azure flute then do the same thing but with electrivire then you will have member card then do the same thing but with palkia or dialga then you will have oak´s letter
First go to jublife city then go to the lotery corner talk to the guy on the second floor say everyone happy then say wifi connection then save then reset go to menu you wil see mystery gift go to it then pick via wireless(you need wi fi for that)
Get mystery gift by talking to the man on the third floor of the jubilife t.v building. For the first question he asks you say "everyone happy" and for his second question say "wi-fi connection". Now that you have mystery gift on your title screen check it every day between dec. 09 and stop around the beginning of june 2010. Eventually you will get the azure flute then get it from the guy wearing green in the pokemart ( he will appear after you have received your the azure flute from mystery gift). Go to spear pillar with a master ball if you have one or at least 50 ultra balls.also bring a pokemon that is at least level 80. Don't forget to save before you go into spear pillar. If that doesn't work than use action replay and google the code.
ps: I know what I am talking about because I have 15 specimens of legendary and I am still working on catching darkrai and I have never used action replay so now you that it is possible to do that.
You could cheat using r4 if you have one then select the cheat "all items / key items" something like that and then you would have a azure flute in your key items. Action Replay Works too , and also the mystery gift...that's all I know on how to get azure flute , I've got a lot of arceus cause I used the cloning cheat once I got one arceus.
Action replay or nintendo event which will happen in june 18- july 1 at any toys r us
p.s. You most have mystery gift to get it go to jubilife city go to the lottoery corner go up 2 floors talk to the man and say everyone happy then he will ask you again and you say wifi connection then he will give you it save and restart and on the menu and you will see mystery gift
Get diamond or pearl then trade any1 legendary to perl or diamond put in daycare until level 100 then when you take out it will have an item its the azure flute put that on a pokemon and send it to platinum ask me if dosent work kk :]
Once you have the national pokedex, and have caught palkia, dialga, mesprit, uxie, and azelf, you go to the store in canalave city and talk to stationary guy next to the counter. He will give you the azure flute. Then go to the spear pillar and stand on the platform with a picture of a flute on it, and the "stairs to heaven" will appear. At the top is the hall of origin, and in which is arceus. He is normal type, but if you give him a plate, he will change into that type. He is found at level 80.
