The desert ruins is the home of RegiRock. To get him type in the Question "How do you get the regis in pokemon" i answered that one and you catch regirock at level 40. Once you've done that you have to use the brail part in the back of the r/s trainer guide Hoped this helped :)
you need to get a wailord and a relicanth and go to pacifilog town and dive somewhere . the pokeworld will shake. go to dessert ruins and a door will be open
open
You get the password from the journal,but its not in it!But its at the top of the ruins.
Go to the desert on route 112 and there are some ruins at the bottom. Once inside read the braille on the wall, and walk left two spaces, down two more and use rocksmash. The door should open then.
well heres what you got to do u go to the gate that's sealed with dots in the tabony ruins i think its on island 6and use HM cut and the the door will suprisely open
The ruins are on Seven Island. You need to go to a cave with a boulder puzzle. You need to put the boulders in the right places so that the ruins can be accessed. When you have the boulders positioned, you will "hear" rumbling on the game and the ruins will be accessible, where you can catch Unowns. If you are talking about the Dotted Hole on Six Island, then the way to get in is using HM Cut on the door. The Sapphire is inside that cave!
Simple you just use cut on the door
go to the desert, go way down to the bottom of the desert, go in the cave, go straight up to the writing press "a" then go right twice and go down twice, then use strenght and the door will open.
use cut at the door of ruins
Forever
sorry but you can't find it in Pokemon diamond/pearl without migrating regirock from Pokemon ruby, sapphire, or emerald. But I think there is a cheat on the action replay for it, but I don't know the cheat.
In Ruby and Sapphire, you have to fight the respective legendary before the doors open.
