I believe that that's not possible.
The sapphire is on Six Island. You need a Pokemon to use cut on the dotted door of the cave.
In Pokemon Sapphire, Latios can be found in Southern Island.
No. In order to trade any Pokemon from ruby and sapphire, you need to find and give the ruby and sapphire to celio on first island.
No.
You'll first find it in the Dotted Hole on Six Island, but a Team Rocket member will take it to their warehouse on Five Island, where he gives you the Sapphire for defeating him (he has very weak Pokemon).
Surf to an island
you have to beat the elite four and go the cleio (you'll find him in the Pokemon centre on the first island) and find the ruby and sapphire. then he gives you the sevii island pass
you get after defeating elite and having sixty kinds of Pokemon and getting the ruby from first island and getting the sapphire from the six or seven island
i don't know ,but i heard you have to get a mirage island compatible Pokemon
get an Eon ticket!!
there is no cinnabar island in sapphire. cinnabar is on firered and leafgreen. also in Pokemon yellow special pikachu edition ^_^ don't forget that dude...
Get two Gameboy Advance SP's and get the link cable and trade, but first you need to get to one island and you need the ruby and sapphire to go into the big machine in the Pokemon centre, you find them on the islands, i think you get the ruby on 1 island and the sapphire 5 island
