its for Soul Silver and I don't know about Heart Gold Press Select and go to box 1 and it should be their I tried it my self and it worked

Have Shaymin as your active pokemon, and simply walk into the flower shop in Goldenrod city. (The little shop next to the towns gym.) The girl will automatically walk up to you. It ONLY works for legit Shaymins. Ones you get from Nintendo events.

It just gave me a bad egg

I've tried that but it didn't work.

Code works, only problem is that wen I add it to my party, my game freezes

Have shaymin in first party then go to the flower shop in goldenrod city and a girl will talk to you and then she will give you a gracidea flower

Shaymin are only in platinum you have to trade to get it

You can't. Sorry.
