I don't think you can.
upload from a gba event.
You can't catch it but only by Nintendo events or cheats.
you need a action replay or a Pokemon event
i just started but there might be ... with Acton replay
you cant unless you use action reply
You must get it from a Nintendo Event or the Pokemon Colosseum bonus disk.
You need a GameCube,a Nintendo wii will work also,get the Pokemon limited edition Pokemon collasemon extra disk(super rare so good luck with that).Jarachi should be on that,catch it,then get a gameboy to gamecube connectors cable,trade Jarachi for something.(the gameboy to gamecube cord doesn't work with D.S. so you need a gameboy,or a gameboy SP for the cable cord to work.) Or just get a Action RePlay gameboy, a gameshark works too, then get the Wild Pokemon Modifier cheat for Jarachi.
that Pokemon is not in Pokemon ranger, Pokemon ranger shadows of almia, or Pokemon ranger guardian signs
Skuntank
You do not catch deoxys in Pokemon ranger shadows of almia.

Munchlax is one of the "starter" Pokemon in Pokemon ranger. If you choose it, it becomes ur partner.
