How do you decode the dots for the regirock, regice, and registeel without..

Use dive on the code when your in the water and then go up and just dig with relicath first in your party and walord last

To get the three Regi's (Regirock, Registeel and Regice)
You need to have a Pokemon that knows Surf, Dive,
Rock Smash and Flash. You will also need a Wailord and Relicanth. You can get a Wailmer from South side of Mosdeep City, train it
Up and it will evolve into Wailord. You can get a Relicanth from
Between Sootopoils city and Mosdeep city while using Dive.
Now you've
Got all the equipment needed you need to go to the ocean currents near
Pacifidlog city. Go to the very bottom current and when you've done
That you should engage a fight with a fisherman. After the battle go
To the bit on the island between the two boulders and Surf in that current. You should then be on a little island with four people on, avoid them. Go all the way to the end of that island and go to the corner at South - West. When there take three steps North and then Surf on the right hand side of you. You will then come to a shallow bit wich you will land on. In the middle of that
Ring of shallow water ther should be a dark patch. Dive in there. Go through the
Door and go to the bottom of the chamber. There will be an inscription really
Blurry wich say's FIRST COMES WAILORD LAST COMES RELICANTH. Put theese Pokemon
In this order and the room will shake. After that go to route 111 in the sandy
Area and you will find that a door has opened, go in there.Read the writting wich
Say's LEFT LEFT DOWN DOWN THEN USE ROCK SMASH. When you've done that a door will open,
Go in there. You will find Regirock -level 40- catch it. After that go to Dewford Town
And then to the cave where you got Flash. Go around the cave while Surfing and go right
As far as you can go. Then Surf North keeping West and you will come across a cave, enter it. Read the writting wich say's STAY CLOSE TO THE WALL RUN AROUND ONE LAP. Follow these
Instructions and another hole appears, enter that and you will find Regice -level 40- catch it. Next, go to Fortree City and go East then West all the way and then you'll come across a cave
Where a man say's he thinks his ancient ruins are in that big rock. Go in there and read the
writting wich say's THOSE WHO ENTERIT WILL SHINE IN THE MIDDLE, this means go to the centre
Of the room and use Flash. Anothe hole will appear, go through it and you'll find
Registeel -level 40- catch it.
You now have the three Regi's.

No, you need the book. Besides you don't need to decode them unless you don't have an Action replay or a Gameshark. They are cheat devices that are helpful for getiing Pokemon and other items.

The first part of Sealed Chamber says "FIRST COMES WAILORD, LAST COMES RELICANTH." This means to put Wailord in the front postition of your party and put Relicanth in the sixth slot. Go to Sealed Chamber and the first hole will open. Go to the next room and have a Pok�mon that knows Dig. Use Dig and you'll unlock the Regi's chambers!

Here are what you need to do in each Regi chamber:

Regirock: Walk up and read the Braille. Walk two steps Left, then two steps down. Use Rock Smash.

Regice: Run an entire lap all around the boarder of the cave.

Registeel: Walk to the center of the cave, then use Flash.

Good luck catching the Regi's, all of them are at Level 40!
