it's just like deoxys, go to the space end caught him good luck :)
No, unless you use cheats or trade it from another game.
you get jirachi by walking(so its roaming) or use game shark or action replay
No, it is for Game Boy Advance.
ruby, sapphire, emerald, fire red, leaf green
I believe you must have a Pokemon game and Gameboy Advance connected to the Gamecube to download Jirachi.
Pokemon Emerald is a role playing game for the Game Boy Advance. There is no such location as the Entora Cave.
You can get it by transferring the Johoto starters via your Game Boy Advance to Pokemon Emerald
You buy the game, and also a GameBoy Advance or GameBoy Advance SP.
You have to get a Nintendo gamecube with the game Pokemon box, start a new game and you'll get jirachi in a egg as a present.
get it in Pokemon colloseum get the Pokemon game pack for ur gamecube and trade it in to fire red or emerald then into ur diamond or preal
Jirachi is being given out by Nintendo through Wi-Fi on the DS, but I don't think it works with Emerald/Sapphire/Ruby. It was meant for the Generation IV games (Diamond, Pearl, Platinum). Otherwise, try and find an e-Reader. They can download a Jirachi onto your game cartridge. Sometimes game shops will use e-Readers as a promotional items, so you can obtain them there...But the margin's slight, and Jirachi is probably THE hardest Pokemon to aquire in the entire Pokemon universe. Good luck anyway.
you can't. No Pokemon game can clone Pokemon except Pokemon Emerald on Game Boy Advance
