You cant catch jirachi in Ruby,Sapphire,Emerald,LeafGreen, FireRed, Pearl or Diamond, without using cheats, or attending certain special events.
HOWEVER
You can still get jirachi into your game.
First off you need a Nintendo GameCube with Pokemon Colleseum and its LIMITED release bonus disc. (Try eBay if you don't have it)
Once you have this you simply connect your gameboy and trade away.
Its difficult, expenisive, and mostly pointless, HOWEVER you can do it

just trade from someone else
you need Pokemon channel for gamecube and you get Jirachi as a bonus.
You can't. You can only get jirachi in ruby and sapphire. You would have to trade from ruby or sapphire.
no cheats
I do not want cheats that do not work
