I wonder if the save would look different if it was extracted by an AR though. Save files extracted from a retail game would have to be done by an AR and I don't know if there's another way. Also, a comparison would have to be made before a pokemon is traded from the XD save to a GBA game, and that same pokemon traded back. The region will become listed as "Distant Land" even if you trade a pokemon that was from that save back so I've heard.
