Wait wait, I remember that Fire Emblem 7 could be used for it, though there wasn't much point. Piece of crap items, anyway. But Fire Emblem 8? Please, enlighten me, how so? I truly don't recall anything.
I think it would have to do with FE: 9. If you connect a completed file of 8 to your GC you will unlock new Trail Maps and Character art. I assume on your PoR file not SS file.
