You have to get Oak's Letter at an event, and then you can access an island of some sort where you can capture a level 30. Shaymin. I don't really know where the island is because I don't have the letter...
Shaymin is an event Pokemon in diamond, pearl and platinum to get it you need oaks letter then he will appear on some route apparently if you talk to him and show him a Pokemon that likes you a bridge will appear and will lead to shaymin.
I think they sent out Oak's Letter during a Wi-Fi event which is needed to catch Shaymin. That's the only way possible to get Shaymin without any cheats.
Through normal game play, you cannot get shaymin without Oak's Letter. Though, you can use an Action Replay (a cheating device) and enter a code to get Oak's Letter to get shaymin. Yo im inproving this answer by saying yo idk y i did this hehe
you need action replay to do this as you get a letter from professor oak to go to route 214 and then a bang happens and shaymin comes out of flower paradise
to get shaymin you either need an action replay or had gone to the event where they give you oaks letter or something.
You must first get Oak's Letter which was released in a wifi event a while back. Without the letter or a cheating device, Shaymin cannot be obtained.
You can't anymore it's IMPOSSIBLE You can only obtain Oak's letter as a mystery gift. This mystery gift was given at selected cinemas for the Pokemon Shaymin Movie. This event has now ended, making it (for the moment) impossible to get Oak's letter without action replay.
