If you really want to help out a bunch, maybe you can bring this to the attention of the weird bandana kid guy on the supercard forums so maybe we can get this compatible with DStwo. I've seen you a few times on the forum while lurking around there.
From what I've heard on behind the scenes dev chatter, the devs (ours, not supercard) have actually got ntrboothax working on the DStwo but they haven't figured out how to reverse the patched bootloader to a working DS card state. Just saying this to point out there's no reason this shouldn't be portable since the DStwo team obviously has more info on the inner workings of the card, and should be able to pull it off.
