There is 3 methods: Gba link cable, Gba wireless adapter and Gba to Gcn cable. With the link cable you can trade with firered, leafgreen, ruby, sapphire and emerald. With the wireless adapter you can trade with firered, leafgreen and emerald. With the Gba to Gcn cable you can trade with firered, leafgreen, emerald, ruby, sapphire, Pokemon colosseum, Pokemon xd gale of darkness and Pokemon box: ruby and sapphire. In each game in the Pokemon center you can go upstairs and talk to a lady that will lead you to the trade center (remember you need the link cable or wireless adapter for this method and you also need another Gba you can also use GbaSP). Once you talk to the lady say Yes to all her questions afterward one of the players must press A twice to enter the trade room. With the Gba-Gcn cable you must save the game in a Pokemon center with the Pokemon you want to trade in your party and in Pokemon colosseum/Pokemon xd gale of darkness you must beat the game then go to phenac city's Pokemon center and go in the basement and talk to the lady to open the trade screen turn on the gba with the game inside and start trading! With Pokemon box you should be able to trade at anytime.
