DOES ANYONE KNOW?

What gamedataextra.iff contains? And can someone tell me which files are the animations for jumpers,dunks,isomotion because i bet those files only need remaing to unlock the other Extra dunk animations like kobe 2.0 , d wade 2.0 , lebron james 2.0. Because it seeems like 2k doesnt give a shit about us and havent released a patch or told us a way to unlock these on the pc version i hope someone can find them or at least tell me which files are the animation files so i can seee wat i can do.

no one knows yet, but it is probably more textures and such that the game uses
