Someone else asked a similar question, I know, but the person who answered simply said:
"your friend's Safari type is based on your friend's FC"
(sarcastic tone) Wow, thanks, I already knew that. I want to know what codes specifically determine someone's Pokemon/type. Like, is there a formula I can use to determine what my friend's Pokemon/type will be depending on their friend code?
I'm sure no one has figured it out yet, and probably no one will for another month or so, but I'm putting this question out there regardless.
