I don't think theres a item code just for Giratina's Orb. Sorry!
No, because it's only available on Platinum.
You need to trade it from pearl it's not avalible any way else
There Is no such code. The Griseous orb did not exist when this game was created. That Is why it is taken off of traded Pokemon automatically in Pokemon Platinum. Having such an Item in your game Would make it Crash.
