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.
Most likely, not yet though. Emerald and Sapphire are basically the same game.
Sapphire and Ruby were released at the same time, then Emerald was released later.
Yes the only catch is you can catch certain Pokemon in ruby that sapphire can't get and vice versa but the pokedex is the same.
Connecting to Emerald as the same conditions as to Ruby and Sapphire. You must have completed the 7 Islands (Giving Celio the Ruby and Sapphire).
Same way you do in Ruby.
Same place it is on sapphire
No. Pokemon Omega Ruby and Alpha Saphire are remakes of Ruby and Sapphire, from 3rd Gen. Omega Ruby and Alpha Sapphire are in the same generation as X and Y, 6. Hope this helps you.^w^
team aqua and team magma, u have to beat them both as opposed to ruby and Sapphire where u only have to beat the team that is the same color of your game(ruby=magma)(Sapphire=aqua)
Team Magma is absent in Pokemon sapphire, but exists in ruby. Same with team aqua in ruby version, both teams only coexist in Pokemon emerald version
