I went ahead and updated the Assembly.dll from GordonBM https://f95zone.to/threads/project-cappuccino-v1-24-3-tentakero.7810/post-1989225. It should work for the latest version. You may need to start a new game, follow the instructions in the post and you should have 500 love tokens to unlock the gallerysave plz
Also, if you ever need to edit the .dlls for Unity games, use dnSpy. For this file, the cheating parameters were in the UnlockController.cs file
