Actually it's possible. If you trade Jirachi in from GBA Games you can play it on XD. There was also a Jirachi event for XD, but that was only if you pre-ordered it before it came out. If you pre-ordered it, a bonus GB Disk came with it and you connect with your GBA and you get it thru that event :)
yOU HAVE TO TRADE IT FROM A GBA GAME
No, but you can get Jirachi with the Pokemon Collesseum Bonus Disc.
Lugia, Zapdos, Moltres, Articuno, Dragonite, and Jirachi. (actually I'm not sure about Jirachi, I know it cmes with a bonus disk if pre-order either Coloseum or XD), but idk which one >_>)
Jirachi is a Mythical Pokemon.
There Will Be A Upcoming Pokemon Event And It Is About Jirachi.
Jirachi is a Steel and Psychic type pokemon.

You need to get the Pokemon Colleseum disk. Jirachi can be traded from Pokemon Channel.
see the question "How do you get jirachi in Pokemon gold version?"
No. Jirachi was only introduced in Pokemon Ruby and Sapphire.
You can't get Jirachi in Outerspace.
I assume you mean jirachi. Jirachi is an event pokemon and is no longer obtainable in the U.S. through any means other than hacking.
