That kind of corruption is different from the one I'm referring to (corrupted carts the 3ds can't even read).
The kind of corruption shown on the video posted a few pages ago is well known and happens if you try to restore a backup before the codes (and therefore the encrypted commands for that particular CART2 cart) have been downloaded.
EDIT:
It looks like Datel also added a Gengar wondercard.
Huh, really? Do you think the poster failed to use the device properly?
That actually makes me feel a good deal better.
