Only you can get it from the preordered special disc of Pokemon colosseum.
No.
The best Pokemon in Emerald version is obviously Rayquaza!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!DUHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! A: YEEEEEEEEEEEEEEESSSSSSSSSSSSSSSSSSSSS!!!!!!! I luv Rayquaza! But technically I suppose Jirachi would be but that's an event Pokemon.
Cheating
Pokemon who don't evolve in emerald version are: Luvdisc, lunatone, solrock, spinda, rayquaza, groudon, kyogre, jirachi, deoxys, regirock, regice, registeel, trophius, kecleon, nosepass, mawile.
Trade from Pokemon colosseum
find it.
There is no jirachi's cave.
Jirachi is a distrubtion pokemon that is not obtainable anymore unless by trading or cheating (gameshark)
you need Pokemon channel for gamecube and you get Jirachi as a bonus.
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.
you can only get jirachi by a special event, which is obviously long gone now.
i think you can only catch it in Pokemon emerald.
