Gen3 Jirachi distribution was carried out in the Pokemon Festa 2003-2005, WHF18, All pokemon centors, Ito-Yokado, JUSCO, Toys "R" Us and HelloMac.
I was not able to see the distribution machine when I received Jirachi in the Ito-Yokado.
But, I discovered the distribution machine used in the WHF and PF.

Maybe they used a Dolphin Development Hardware. They seem to insert the cartridge in the 5.25 bay.
I think that the salesclerk of the Ito-Yokado, JUSCO, Toys "R" Us and HelloMac used GameCube disk, because I handed the cartridge inserted GBA to a salesclerk of the Ito-Yokado. Probably they were not able to operate the development machine.

It is thought that the distribution method is similar to Festa Metang when I watch the images.
