In sapphire you cannot get Groundon and Latios without trading or cheating.
You have to send migrate it from Ruby, Sapphire, or Emerald Pokemon games to the pal park.

Sadly, you can't catch Groundon is the Sapphire Version, however you can in the Ruby version, you will find him in the same place you find Kyorge in the sapphire version.
gold is from joto and groundon is from hoen if you want groundon play ruby,Sapphire or emerald

Rayquaza,kyogre and groundon are second rarest!hope it helps! ^_^p.s.obviously Pokemon you cant get on sapphire,but can on other gba games E.G....chikorita, are the rarest! "_"
Groudon cannot be obtained in sapphire only ruby and emerald can get groudon.
you dont need an action replay for groundon, just go to the weather institute, a dude will tell you about weather conditions in an area. if it is realy sunney there will be a cave near by. inside will be groundon.
