Guys, lately has come to my head a question, that is what would be need to deeply change PES like in core mechanics, tactical functionality and others. For what I know from other games modding, we would need the code of the game, I guess, or some way to access the graphic engine of the gamr. Does anybody knows what kind of language does PES engine use? I guess it would be necessary to reverse engineering the game, right? Dunno know if there's somebody to get that deep in that community and/or if it would be worth or it would create some problems with Konami, but it might be worth, since a lot of the playability are tied to this core mechanics.
