I'm on to that. You know the town Dewford? Go north and when you see an Island with a ruin maniac, go to that island, and then go to the island that's to the right of it and you'll see a path. On the end of the path, you'll see one big rock surrounded with six little rocks. I think one is there. Then go to the left of Lily Cove and when you get to the girl that gives you an Iapapa berry from and go up those stairs. Go as north as you can and then you'll see a ruin maniac and a big rock surrounded with six little rocks. Coinsidence? I think not! If you were wondering, I haven't found the third one yet.

In your dreams.
There is a little hole in the rocks near the water. You will find the regi rock there.
In the snowpoint temple you need the 3 regi's from ruby,sapphire and emerald to wake up regigigas.
by getting all three regi`s from Pokemon emerald, then you can go in and find the fourth regi. (Regigigas)
DotBraille is Regi's language in Ruby, Sapphire and Emerald. By reading them in the walls and de-coding them, you can find Regi's (expect Regigas!).
i do not to know
BF4 in Snowpoint Temple
Actually you're wrong you can NOT get the regis in Pokemon diamond, to get the regis you need Pokemon ruby/Sapphire/emerald you can get all three regis there(regi ice, regi steel, regi rock) althought if you migrate all of the regis onto Pokemon diamond you can get regi gigas(king regi) you will find him in the snowpoint temple after beating the elite four. Thanks hope i helped ^.^
in Almia castle
You have to get regi rock regi steel regi rock then go to the tempo in snowpoint only(soul silver ,heart gold,dimond ,pearl,and platnium)
