hmm can you screenshot me where you placed the folder? Its seems like the file was not detected, mainly the title file itself thus making it unable to run, the nsfw art is not in the game gallery deliberaty but it is irrelevant to the issue as the error is due the game not finding where you put the patch folder.
Also did you make sure when unzipping, you did not create another folder by accident? So the folder PATCH is inside the game folder and there isnt an additional PATCH folder inside the PATCH folder?
Also Is the Art folder inside the PATCH folder as well?
