Once you've got all channels, go to I think options on the main menu. Then go to "Jirachi". Transfer it to R/S/E. But you must have beaten the Elite Four with your OWN Pokemon on those games.
It also works in the Australian version. Which is how I got my Jirachi! ;385;
Oh, I was just wondering, is it only 1 per Pokemon Channel game or 1 per game cartridge? If I start the game over again can I get Jirachi on my sister's cartidge too?
You can get 1 Jirachi per cartridge. If you want another one for the cartridge you've already downloaded on then you have to start it agian and get it to the point so you can dowload another one. That's how I got my 5 Jirachi from Pokemon Channel.
I've used the same Pokemon Channel file (my first one)for all my Jirachi downloads. It's actually become my downloading machine now.
"If you want another one for the cartridge you've already downloaded on then you have to start it again and get it to the point so you can dowload another one."
Does that mean to restart Channel or the GBA cart? I assumed it meant the GBA cart, but I thought I'd check.
