Two new slaves have been released, both early, vanilla releases
Released by CM Tyssen, Sakuya is from Touhou. She is vanalla at the moment. Also there are some image issues with her, some in the naming for her files, and some a bug in the core game.
vash99 has released Ran from Detective Conan, also a vanilla release.
a) rename the included file
to the next free number (SlaveGirl40.txt for Sakuya, SlaveGirl41.txt for Ran)
b) copy the SlaveGirlxx.txt, Slave-xxxx.xml and the Slave-xxxx.png into the folder Slaves in your game installation
c) copy the folder (Sakuya or Slave-ran) into the folder Images
For Ran, just extract the new link above into your game installation folder
That should be it, they will work.
Note a new game release is needed for the image issues for Sakuya but I will not be able to release one for a while (a week a best)
