Unfortunately you could only get Jirachi as part of a Pokemon event, which is now over. Sorry!

No.
yes
Cheating
There is no jirachi's cave.
you need Pokemon channel for gamecube and you get Jirachi as a bonus.
Trade from Pokemon colosseum

yes with an event.
im sorry but i might be able to help you if it was a little bit more clear _yeah what was the question???-
you can only get jirachi by a special event, which is obviously long gone now.
