Yup! I can hack my legit 3ds id i want just because of that game. YaaaaayI'm pretty sure it has been pulled for awhile now.
Dsiware isn't "dead/over" necessarily.
I would consider it dead/over for those who never got to download one of the games or TLOZ: 4 Swords while it was free (even though it's pulled, you can get it from "Re-downloadable Software" if you've downloaded it before)
So for lucky users like me, Dsiware downgrade will still live on forever.
