no you cant
You just need a link cable.
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).
Unfortunately, you cannot use the Wireless Adapter with Ruby or Sapphire. Bit you CAN use a Link Cable to trade between Ruby, Sapphire, Emerald, FireRed, LeafGreen, and Pokemon Colosseum I dont know how Colosseum works though. Hope This Helped! Shinin PS Colosseum is latin. the translation is "Huge Arena"
Sapphire and ruby are oxides of Aluminium Sapphire and ruby are oxides of Aluminium
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
Sadly you can't without cheating. You must trade it from Ruby or Emerald to your Sapphire.
The ruby and sapphire are on fire red and leaf green don't worry about the in ruby sapphire or emerald.
The Sapphire Needed to connect with Ruby, Sapphire and Emerald. But some Guy steals it from you and tells you a password for the rocket base
