just 4 u 2 know ... how 2 catch the regi-s
1.bring pokemonn that can du DIG, SURF, DIVE, r
elicanth and wailord (wailmer lv 40)
relicanth can b found under the sea of sootopolis
if u dont want to waste your TM28 DIG, you can train nincada 2 lvl 45 and learn that move
2.from pacifidolg surf left and just follow the current at the bottom side. u should c a clear water without current then. you can catch horsea there and get the dragon scale to evo the seadra to kingdra with link cable. from that spot, stand on the left center side of that land and go with the flow again. just follow a few curent and you should see a dive spot. if you failed to reach it just do it again until you reach it
3.dive, follow the way, see the brailecode that means = GO UP HERE. just use dive again/ press B buton
4.SEALED CHAMBER
1st room (the others are worthless)= USE DIG HERE --> jjust use DIG
2nd room (the others are worthless) = FIRST COME RELICANTH, LAST COME WAILORD --> put relicanth on the first order of your party and wailord last. you should hear an earthquake. now get outta here. use dig to save time
5.DESERT RUINS = bring pokemon with
strength move. from this point, you don't have to bring your relicanth and wailord again
desert route 111, to the bottom of it and enter the cave.
Braile code: RIGHT, RIGHT, DOWN, DOWN, THEN USE STRENGTH
follow the code and there shall open a new entrance.
SAVE!, talk to the REGIROCK and try to catch it!!! it not as hard as kyogre groudon.. but it still needs luck
for future reason, I always catch any pokemon with ordinary Pokéball. I feel so lucky when catching this pokemon, because it only needs 5 pokéballs without harming the regirock. I have my 200 hoenn pokemon complete on gameboy advance (I have 2 GBAs and 2 disc one contain ruby n sapphire and another contain sapphire.
6.ISLAND CAVE
North-West of Dewford Town, Navigate your way through the maze of small islands and you should find the island cave.
Braille code : STOP AND WAIT. WAIT FOR TIME TO PASS TWICE. after you read it, stand still and dont push anything for about 90 sec. and good luck! catch the regice.
7.ANCIENT RUIN <-- i'm not really sure bout this name

and bring pokemon with move fly
Route 120 (near Lilycove). the ancient ruin is a few levels up and through a patch of grass.
Braile code: WITH NEW TIME, LOVE AND HOPE, AIM TO THE SKY IN THE MIDDLE."
go to he middle of the room and use fly. happy catching registeel!!
regirock has extremly high defense and high attack
regice has extremely high sp.def and high sp.attack
registeel has both stat high but not as high as regirock defense or ice sp.def.
the sad part: i met trainer with 3 regi in battle tower and they are REALLY REALLY ANNOYING. 1 beat those 2 and lose on the registeel
Pokémon : gotta catch them all™
