+You might be wondering why I bothered implementing sex toy support. I do not have a clear answer to this question! I wondered how I could implement rumble support and since a PC cannot (usually?) vibrate, my brain came up with a vibrator feature.  
+
+Lovense support is not compiled-in by default, however, it is available through the `nsfw` feature flag during compilation. Enabling this flag will force the emulator to start searching for nearby Lovense BLE products and connect to the first that matches a specific regex if rumble support is detected for a game.
