use action replay
if you have action replay you will get to pick a pokemon so groudon is a hard pokemon you need the red orb for groudon on pokemon soul silver version or pokemon heart gold version but use action replay on pokemon pearl,diamond,platinum
As of now, no action replay codes are reported for Pokemon Platinum.
What?!?
action replay does not work for platinum because platinum came out a long time after action replay but there is another version coming out go to codejunkies.com if you would like to have a look.
get an action replay and get a code for that Pokemon
No, that is only for the Platinum version.

You use the action replay, or get an event. The last way is the GTS.
