For eshop purchases and such, a ticket is also sent to the 3DS (and is stored in the NAND, not the SD, so you can't just copy it around) that the 3DS requires in order to run it (so people that downgraded their NAND to an earlier dump after buying an eshop game found themselves unable to run it even with it still downloaded on the same SD).So is it signed for that specific 3ds before its sent out? or could you intercept the signed file and then use that on everyone else's system.
