Same way you do in Ruby.
Go up Route 101! ^_^
in Pokemon sapphire/ruby you need to go under water in go into the grass it might take a while but keep trying and don't give up.
You have to go up,then right,then down and surf
i dont have sapphire
It is impossible to get Palkia in sapphire. Palkia is a fourth generation Pokemon and sapphire only has Pokemon up to the third generation.
you go to roky places up hills
Catch a Zigzagoon he picks up stuff as you go.
As far as the game goes, you can't duplicate Pokemon on Sapphire. Tried it and it glitched up.
If by sapphire you mean kyogre (cover star of Pokemon sapphire) beat team aquas base,find them underwater on route 128 go up through the cave and he runs off.go to cave of origin.
get a cable or link that connects into two different gameboys, go to the Pokemon center(up stairs) and go to cable club
The sequence is: up, left, right, down.
Go to your room in ruby and sapphire or emerald you will see a gamecube hooked up to your tv.
