Hey I know this will seem pretty random and I'm not sure if this is allowed here or not, if it isn't I apologize and you can just delete this post (not that you'd need my permission to though :P ). Anyway does anyone know if full sprite sheets/rips exist for this game and where I might be able to find them? (I'm really just looking for Mamiya, Rei, and Ken.) I've been searching Google and just about every other site I can think of for I don't know how many weeks now and found nothing outside a few random sprites. If anyone can help me that would be great, if not I guess it's back to Google for me. lol
