Yeah, I figured it out after I had asked the question....*feels foolish now* I got them all onto AR just fine, and had to fiddle for an hour or two with the codes and more them all use L+R to load
(for some reason that one line of code...B21C4D28 was off, and I had to correct all six codes so that the last bit read the 4D28 part...)
So I got them all checked out, all were legal, and I loaded them on and traded them over! :] They made it through the Elite Four no problem, and I've been playing in the battle tower with them ever since.
And I got to do a battle with one of my friends with them and they won their first ever match!
