Well, I have a bunch of expansions that I don't know what they do separately, but together u get the pose editor, uncensored, some more clothes, and the ability to change the "features" of the girl (like height, bust size, etc.) For the application file (ObsDX9), you just have to replace the one you currently have with this one. The rest of em, just put into your "arcs" folder located inside the 3DCG folder itself.
