You can't.
without cheats,you need to receive the oak's letter in the Nintendo event
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.
You can't. you need the the Oak's Letter which is only obtainble through an event or you can use action replay.
You can't get Shaymin in Heartgold and/or Soulsilver without cheats.
you have to do prof. oak in bed then he gives you the Oak mail you have to battle prof. oak then he gives you the Oak mail
No
no you because the event of shaymin is over now
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 can't catch Shaymin without cheats or a Nintendo event.
You can't get him without events or cheats. For Darkrai, Manaphy and Arceus you need a event to capture him.
im afraid it is not possible but you can stilll get shaymin,heatran and cresslia without cheats
Only from event
