Catching Regice in Ruby Version Pokemon for GBA
First, you need a Relicanth, Wailord, and a Poke'Mon that knows the move dig.
Then you fly to Pacifilog Town and surf left to the water rapids. It will take a few tries but eventually you will come to a small area in the shape of a square where you can use dive. Head all the way south until you find a square-shaped wall with brail. Read the brail then use the move dig. Head north ignoring all the other brail until you reach the wall on the top of the screen. There will be more brail. Go to the middle section of brail, read it, and use dig once again. Go north to the back wall, put Relicanth in the front of your party Poke'mon and Wailord in the back of your party. Read the brail by clickng A and the screen will shake. Exit the underwater cave, and fly to Dewford City. Surf north and be alert to look to the left of the screen. You will see a small, thin island about 3/4 the way to Rustboro City. (NOTE: There will be aswimmer at the bottom of the island. Surf past him to the left onto the island.) Go north until you find a giant rock in the water with six small surrounding it. There will be an entrance in the biggest rock in the center. Enter it. Go to the back wall of the island cave. Read the center brail section.(Relicanth and Wailord must still be the way I told you before.) The brail is translated into something like "you must be patient" or something. You have to stay in the exact position you were in when you were reading the brail code. If you move at all you will have to read the brail again and wait. You must wait exactly 2 minutes before you can enter the soon opening cave after you've read the brail. So you might want to get something to drink or something while you wait or just sit there for the time. When the cave opens, you enter and Regice is sittng there waiting for you to click on it. Save the game unless you want all of your data of this lost. Battle and catch Regice in the battle.
