On the supercard forums, they're recommending exchanging DS2s that don't work in a 3DS and XL. Sounds like most of the older ones work while the newer ones are the ones with a tendency to work in a DS/DSi but not a 3DS/XL...
Haven't gotten around to getting a 3DS yet... (waiting for it to actually be useful, i.e. cracked wide open before I bother as there just aren't enough official games that interest me... same with vita...)
