trade them
By migrating from Pokemon emerald is wrong,a bit there are three ways 1.by migrating 2.by trading from Pokemon ranger 2 3.or you can get them on platinom (4)you can get from action replay 4 is easier but is cheating
I believe their isn't a code you can't get the regi's in Pokemon pearl unless you trade.
nothing, there just there to catch to fill out your browser.
Trade someone with Ruby,Sapphire,and Emerald.
You must Migrate from Sapphire, Ruby or Emrald.
you can't catch any of the three regis on any DS game except platnium.sorry:(
I think you have to transfer the three regis from platinum version to pearl version but you have to have platinum version I think that's all I know
It is only possible by cheating.Not by regular gameplay.
you cant get the three regi's in heart gold or soul silver. You can only get them in Pearl, Diamond and Platnium
either you get Pokemon emerald or Sapphire, and if you want them on diamond or pearl you have to beat the elite four and then migrate.
First get all other 266 Pokemon in the Browser then you will get a mission to go to hippodon temple. Catch the 3 Regis then go down a hole in the temple put the three regis on these things then you vs Regigigas
Regigiga can be found in the Hippowdon Temple on Pokemon Ranger: Shadows of Almia. To find him to need to have completed all 60 quests, completed the Browser and have the three Regi Pokemon with you. After finishing the above a secret room will open in the Temple with three places to put the Regis. Once you put the Regis on the pedestals Regigigas will appear for a battle.
