get a kings rock (mossdeep) and ever stone(granite cave) then wish tag and go to metor falls and smash a rock then WA la but try loads of times until.
Go to Wish Island or use a game shark and walk in grass
If you pre ordered Pokemon colosseum you got a bonus disc that you could get jarachi and put it on ruby/sapphire
You can't get Jarachi in ruby, sapphire, and emerald. It can only be obtained with a gameshark, action replay, another cheat device, or a Nintendo event and there hasn't been one since 2002 as far as I know.
Sorry no.
No, you cannot breed legendary pokemon...
I don't think you can.
Umm.. You Might need to migrate from Pokemon emerald
upload from a gba event.
You can't.
You can get it from an event which you can't anymore, from the Pokemon Collosseum Bonus Disk, or from the Pokemon Channel.
Can't find Jirachi without trade or migrate
You can't Yeah that's 3rd gen...
