>>55306067>they are at the top of the volcano to get the orbNo, you're conflating the two mountains in Hoenn together. Team Aqua is at Mt. Chimney to use the meteorite Professor Cozmo found to extinguish the volcano, so it can fill with rainwater and provide a new habitat for aquatic Pokemon. The player chases them off and takes the meteorite back. This plotline is in Emerald as well. The Red and Blue Orbs are found at Mt. Pyre, south of Lilycove. Team Aqua steals the Red Orb, Team Magma steals the Blue Orb. They can't control Groudon and Kyogre with them because the idiot leaders stole the wrong orbs.
In RS, Groudon and Kyogre sleep in the Seafloor Cavern, then move to the Cave of Origin in Sootopolis City after being awakened. That's why Team Magma still needs to get down there. In Emerald only Kyogre sleeps down there, while Groudon sleeps in Mt. Chimney. So instead of steal the submarine Team Magma digs into the volcano to reach its base and awaken Groudon, who them digs down to reach Sootopolis.
