trade
You need to get the Pokemon Colleseum disk. Jirachi can be traded from Pokemon Channel.
No, it is inpossible to catch Jirachi on Diamon, Pearl or Platinum.
You can't catch Jirachi.
You must trade it from FR/LG.
You can't catch bastiodon in Pokemon soulsilver.
I'm afraid you can't catch Jirachi in Pokemon Soul Silver. You have to have a Nintendo Gamecube, a Gameboy Advance/SP, the Pokemon Colosseum Bonus Disk with *Special Gift Jirachi,* Pokemon Ruby/Sapphire, and a wire to connect the Gameboy Advance/SP to the Gamecube. Then, you download Jirachi onto your game, and Import it onto your Soul Silver game via Pal Park (I believe it is in Fuchsia City) and then you have a Jirachi! I hope that made sense and helped you get a Jirachi.
Again, Jirachi is an EVENT Pokemon! (sorry for sudden rudeness, I've answered many stupid questions like this one -...-) There was a Jirachi event for Diamond and Pearl that once you traded it to HeartGold/SoulSilver, you unlocked the PokeWalker route, Night Sky's Edge
find it.
To catch JIRACHI you have to use the Pokemon colloseum disk. To catch DEOXYS you have to go to a Pokemon Nintendo promo event and get the aurura ticket downloaded on your game.
You cannot capture Jirachi on Soulsilver but you can migrate one from Pokemon Emerald, Ruby, or Sapphire which you had to have obtained from an event awhile ago. Unless you have something like Action Replay.
