Basically so far the end answer is it seems it's mostly useless if you don't have a donor cert file for your personal use to amend to your downloads, and the safest way to do that is to have the dumper and grab it off of one of the carts you physically own rather than get one from someone else who you can't guarantee the safety of. Imma wait the long game, and if by the end of the year there hasn't been any crackdown on people using their own homemade donors, I'll probably get one, assuming a better swap method doesn't appear by then. I'll probably also get one of those third party docks with the remote controlled game swapper thingie too just to avoid the tedium of physically ejecting the cart repeatedly, as they've been proven to work fine with the cart.
