Is it possible to get that 'high res CG file' archive in the game directory, which is 300mb big and password protected?

This is that file, but compressed to JPG. I can't really see any compression artifacts but if you want to open it yourself for the sources they give you the number code after you finish the game, which is just basically just clicking all the options until its over.
