honestly dude i dont think you can trade from sapphire period.
The elite four will open the door and they will become stronger than before. You can now trade with ruby, sapphire and emerald
fire red: after you give the sapphire to celio, now you can trade with Pokemon ruby, sapphire and emerald
FireRed. If Ruby, Sapphire, and emerald you must have Ruby and Sapphire gem and give it to celio in one island
You can trade with Sapphire and Ruby
The elite four will open and they will be stronger and you can now trade with ruby, sapphire and emerald.
The sapphire and Ruby (you can find both in the game) allows you to trade with Pokemon ruby, sapphire and Emerald version give it to Celio and when you give both to him it will allow him to connect with the Hoenn region allowing you to trade with those versions
Give it to Celio on One Island. You also need the Ruby. Once you give both to him you will be able to trade Pokemon with Ruby/Sapphire games
After giving the gems celio gets the machine up in running this means you can trade with any hoenn game by going upstairs in any Pokemon center and going to the trade center using either a GBA link cable or wirless adapter you can now trade with ruby, sapphire and emerald and now you can own hoenn Pokemon.
The Scientist that took the Sapphire is in there, and if you beat him he gives it back to you. You can give it to Celio and then you can trade with Ruby and Sapphire!! Hope this helped
You give it to Celio
Well, i heard that you need to get the gems to be able to trade to ruby and Sapphire get it? retrieve a ruby and a Sapphire?
Yes if you give Celio the ruby and sapphire he connects with Lanette and all Hoenn trainers this means you can now trade between ruby, sapphire and emerald and even Pokemon colosseum and Pokemon xd gale of darkness.
