How do you get Groudon and Kyogre. Please answer?

This information applies to the Emerald Version.

You must defeat the Pok�mon League and find Groudon in Mount Chimney and Kyogre in the Seafloor Cavern.

If you want to Know this detailed Then go to the Hints site but Anyway just beat the elite 4 and go to the weather station on route 119 and go to a route the man says there should be a suspicious diving place or cave there.

Your wrong Cross Stinger! You do have to beat the Pokemon League but you find Groudon in Terra Cave on Routes: 114-116 and 118 and Kyogre in Marine Cave on Routes: 105, 125, and 127.

Go to Terra Cave and Seafloor Cavern after you beat the Elite 4.

You can get Kyogre and Groudon. You must beat the elite four. Then go to the weather institute & talk to the scientist. He will tell you that a drought or heavy rainfall is near a route.

If the scientist says there is a drought, a cave will appear in that route & groudon will be in there. If the scientist says there is heavy rainfall, you will need to dive underwater to find the cave.

If there is more than one area to dive in an area where there is heavy rainfall, try to find the cave underwater. Kyogre is in the Marine Cave & Groudon is in the Terra Cave.

If you take too long finding them, you must go back to the weather institute to find there new location.

Everyone you are wrong! After the Elite Four there should be a guy at the Weather Institute
By a computer speak to him and he should say, route so and so is raining a lot( KYOGRE)
Route so and so has to much sunshine (GROUDON). For Groudon after speaking to the man go to the place he mentioned that was sunny. And look for a cave the (sunny area should be at a mountain) and after you find that cave enter and there is a Lvl. 70 Groudon!
Save before you battle!
(KYOGRE)
Speak to the man at the Weather Institute and go to the place that he says is raining and you should see a dive position (Deep Water) that you do not normaly see. Well dive and there is a Lvl.70 Kyogre!!

Mine went like this. After I defeated the Elite Four and Wallace, somebody delivered an S.S Ticket to my house and then I went to the ferry. You talk to someone there and they'll talk about strange weather patterns. (These are obviously caused by kyogre and groudon.) I went to the Weather Institute at Fortree and talk to the Professor there. It depends on what he'll say whether it's drought or heavy rainfall. For me, he told me about the drought first at route 114, but there are a lot of routes where drought could appear. I found a cave(terra cave) and saw groudon. I used master ball to capture him.

For Kyogre, I found him around route 104, around Dewford. I saw a place where I could use Dive. Make sure you have a Pokemon with you that can do Dive. I Dived then found the marine cave. I made sure that the battle went on for a lot of turns then I used a repeat ball. It actually worked!!! They only give out master balls once in this game unless you win the lottery at lilycove six times. I haven't won it yet though. And they don't always give you the master ball. Okay. That's about it.

You can get as many masterballs as you want by using the copy glitch look it up it works I have 99 masterballs
