MP,
I hate to be a critic or a skeptic here, but I think the credits were wrong. In fact, I believe it may be the retexture I was mentioning (but converted to SFC3). As I said, Knox1711 used a lot of P81's work, so a newcomer could probably confuse the two as the same person (especially given that Knox1711's name, sans the numbers, is the same as P81's real last name).
Again, I could be wrong here (bad memory always a possibility for me), but... *sigh*
