Hi! You can try to find a program on the Internet that extracts .rpa files.

Hey! I finally got into doing it but I couldn't find what I was looking for, which was artworks of some of the sceneries and sex scenes(mostly the stills and not the animation.)
I only found an images folder which had Armwrestling, Backgrounds, Menu, and Napertski in it.
I also apologise if I'm inconveniencing in some way with these requests. I just really love the art style that your game has and want to get hold of some of them.
