raquaza;raquaze is on skypillar,go to the city that is floating on the water and head rightr(where don;t have the waves)and go up and find skypillar,you need mach bike to get to the top.

unlock the caves:bring a wailord and a ralicanth,go to the city where it is floating on water and head to the waves and get to a place where you can dive and go in and go deeper in and read the words on the wall and dive up .you will find yourself in a cave then go ans read the words on the wall,and use dig,and another door will open,go in and read the words on the wall again and put wailord first in your team and relicanth last and the cave where the regis are will unlock.

regirock;To find the cave of the rock titan Regirock, you must have the Go-Goggles so that you may enter the desert. Once in the desert, go south to the bottom and enter the cave. In the back you will see the Braille in the back. Go to the back of the room and read it. The message translated reads "Left, Left, Down, Down. Then use Rock Smash." From the middle of the Braille on the wall move left, left, down, and down. Go with a Pokemon that knows Rock Smash and use it. The cave door will open. Save the game, then start the battle with Regirock. Note: Bring a lot of Ultra Balls

Registeel
To find the cave of Registeel, go to Lilycove City. Go west through the grass and trainers. When you reach the area of the Safari Zone, keep moving. You will reach a place with a girl. Just above her are stairs. You must go up. Go through the very tall grass and go up the stairs behind it. The cave will not be too far after the stairs. Once inside, read the Braille at the back of the room. It reads "Those who inherit our will, shine in the middle." The riddle means that you should go to the middle of the room and use Flash. The cave door will open. Be careful with Registeel. This Pokemon is more difficult than the others to capture. Try bringing a lot of Ultra Balls or prolong the battle as long as you can by freezing it or putting it to sleep. After many turns the Timer Ball will have gained a lot of strength, and it might work against the Registeel.

Answer 2

Deoxys Jirachi and Mew require a Poemon journey to get. Ho oh and Lugia are purely obtainable in Gold and Silver regrettably and the three birds are not in Emerald the two. Mewtwo isn't the two lol. Rayquaza is in the Sky tower yet I forgot and Kyogre and Groudon too are someplace XD. Regice Regirock and Registeel additionally are someplace in the Hoenn area. regrettably it is all i comprehend.
