umm so I'm at the end of the game at disc 3 ( all that's left to do in the story is to enter the north crater and defeat Sephiroth ) and my black chocobo refuses to mature enough to uhh ... do his thing with the S class yellow chocobo to produce a gold chocobo ... I've tried a few things like letting the game clock pass a few hours while riding the chocobo ... nothing seems to work . Anyone know what's necassary for the chocobos to pass out of their "too young" phase" ? thanks
