What the requirements to caugh the all regi Pokemon?

Answer 1

You catch them on pokemon sapphire. Do the following to get the regis:

1) Get a wailord and relicanth and put them in the back of your party (sorry, I forgot what the order was).

2) Get the hm of dive.

3) Go to Pacifilog and keep going west until you get to a small dive spot. Use dive here. If you get to another town (sorry, I can't remember the name of it) you will have to fly back to Pacifilog and keep going until you find the dive spot.

4) Go down to the bottom rock, read the braille and dive up.

5) Go up and read the braille. I think this is where you use dig.

6) Progress up and read the braille. This is where your wailord and relicanth come in the picture. You will then hear 3 loud cracks.

THEN:

Regirock- You find regirock in a cave in the desert. Go inside, read the braille and do what it says. (Search online for a braille chart if you have to).

Regiice- I'm really sorry but i don't know exactly where regiice's cave is, but i know that it is somewhere near dewford. When you find the cave go inside, read the braille and do what it says.

Registeel- You will find registeel in a cave on the route past toe town with the flying gym. Enter the cave, read the braille and do what it says.

After catching all the regis, you can transfer them onto pokemon diamond, pearl or platinum and use them to get a regigigas.

Good luck and i'm sorry if i was unclear in any way
