Shouldn't the SNSP be AFZP? From what I recall all SNES games that had 4 letters in the PN differ in different regions by the last letter (J = Japan, E = US, P = Europe). Also there should be an additional string at the end: -EUR, -NOE, -FRA, etc.
(Yeah, kinda old topic, but I haven't been online for a long time, and I'm just catching up.)
