How do you get sky formed shaymin in Pokemon Platinum?

Answer 1

1st of all, you can only get shaymin sky form in Pokemon platinum and you need action replay. Once you have action replay, type in 94000130 FCFF0000 62101D40 00000000 B2101D40 00000000 0000B5D4 00000009 0000B5D8 00000000 D2000000 00000000 and go to a pokemart. while you are going in press l+r at the same time then talk to the Pokemon ranger (in green) he will give you Oaks letter then you go to route 224 and talk to proffeser oak and he asks you a question. once you answer it a path opens up which leads you to shaymin LAND form. Catch shaymin and put it in your party. fly to floroma town and talk to the girl northwest of the Pokemon center. She gives you the Gracidea flower (which is a key item) use the flower on shaymin and it turns into sky form.
