Saves are in www\save directory inside game directory.
It is not sufficient to just copy save file into that directory as game has generic state file that tracks all saves. Your copied save file must replace other existing save file that is already registered there or you need full contents of save directory.
Hey guys, I already unlocked all scenes and progressed all girls quests, but i don't know how to unlock the last scene. It tells me to talk to Barbara but she doesnt say anything. How do I unlock it?
