it is a small accessory that attatches to the top of your game boy advance/game boy advance sp... it enables the interaction between the games emerald, fire red and leaf green... NOT!! rubt and sapphire
You have to buy one.
U can trade with the help of a wireless adapter.
No one in the game trades you rattata nor pidgey if you want to trade those Pokemon use a link cable or wireless adapter to trade with leafgreen or another firered.
okay the wireless adapter isn't just for fire red for one and a wireless adapter is what you use to hook up 2 game boys together wirelessly.
I don't think you can catch celebi at all in fire red. There is one way though bring your gameboy/ds with a wireless adapter to a Pokemon convention to get celebi.
Saphire and Ruby arent adaptable with the wireless adapter, so when trading to those games you cannot use one.
can you get an wireless adapter
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"
You have to get the Aurora tickett by the wireless adapter if u have one.
when they made firered and leafgreen, the game cases included wireless adapters, which connect to the input slots on the top of the gameboy advance or the back of the gameboy advance sp. in emerald, if you want to get the mytery gift, you need one of them. i think they sell them seperately now. im not sure.
You cannot find or catch Dratini in Emerald. You can trade it over from FireRed or LeafGreen.
Simply attach it to the top of your GBA if another GBA close by has one as well you can use them to trade Pokemon in firered version, leafgreen version and emerald version. That unfortunately was its only use.
