Oh crap! I got it!
Following this thread:

Used the plugin folder from there along with naming the game folder "Birthright". So now my card looks like:
SD:/plugin/0004000000179400/layeredfs.plg...
I have Luma 3DS Custom Firmare and NTR 3.2 on an old 3DS. I am playing a real digital copy of Fire Emblem Fates: Birthright. I cannot get this to work on that version, I believe everything here is targeting the special edition specifically?
Is there anyway I can unlock the hero paralogues on...
