I don't know if the Lovense integration would work via Gamcore, but can you at least add the Stray Pubes DLC to the game (and actually fix it so that the game can run on Gamcore)? Thank you, here is the link to the updated game and its DLC!

I found a download for the game in case the Steam link doesn't work, here it is!
