Not long after the Rosenkreuzstilette ~Freudenstachel's~ C75 demo was released in December 2008, fans of the series went to work creating modifications to the first game. The mods were popular among fans, and most of them were mods to change the sprites and portraits to make them as seen in Rosenkreuzstilette ~Freudenstachel~. Currently, all the mods released are only graphical mods.
