Use a GBA link cable.
Yes, you can.
no, you must use a gameboy link cable
You can link and trade Pokemon with Sapphire and Emerald Versions. If you want a national pokedex, trade with leaf green version
Ruby, sapphire, emerald only by wireless adapters, another firered, leafgreen and Pokemon colosseum and Pokemon xd gale of darkness.
From what i heard you cannot get KYOGRE in ruby.
No, you have to migrate it from Pokemon Emerald, Ruby or Sapphire. No, you have to migrate it from Pokemon Emerald, Ruby or Sapphire.
no you can either transfer from Pokemon ruby, emerald, or sapphire using the game link.
you cant but you can trade it from ruby, sapphire, and emerald or use the action replay.
you get either Pokemon sapphire or ruby and you link and restart the whole game on ruby or sapphire pick out a Pokemon and get to a Pokemon center and link to the other gba and trade for another Pokemon and repeat like twice
Why yes! :3 You can simply trade them, in the 2nd floor of the Pokemon center. However you have to use a game link cable.
You have to have two Game Boy Advances to trade with emerald and ruby and a GBA to GBA link cable, another way to trade is if you use a GCN (gamecube) to GBA cable and you use Pokemon colosseum or Pokemon xd gale of darkness to trade emerald or ruby Pokemon to there then use colosseum or xd gale of darkness to trade your emerald or ruby Pokemon to the other game either ruby or emerald. Theres no way you can use a DS to trade with GBA games because the DS is not compatible with the GBA link cable.
Kyogre Is Not Avalible In Pokemon Ruby. Just In Pokemon Sapphire/Emerald
