About This File
This promo card was only available to Japan, and even then it was not easy to come across one.
There are only 1,000 copies in existence, and it was mailed to lucky winners,
who mailed-in proof that they purchased at least 6 e-reader booster packs during the promotional period.
This promo card does not store itself in some way on the save,
so it could not be extracted like e-Card Trainers and e-Card Berries (as .ect and .ecb respectively);
it basically ends up directly adding the doll to your save, not particularly different from the way this tool works.
Additionally, @HaxAras has a page that provides a bunch of saves, as well as detailing how to transfer the dolls onto an international system.
In order to use this .raw, users will need a VBA link with e-reader support.
Instructions on how to use the VBA link with e-reader support can be found here.
