Introducing the new version of my TranslateNX project, which completely revolutionizes the real-time in-game translation experience on the Nintendo Switch! With this application, you can instantly translate on-screen game text into your own language. Moreover, this release brings brand new, lifesaver features!
Key Features
Easy API Management via PC and Phone (Web Server): You no longer need to type your API keys one by one using the Switch keyboard or plug your SD card into a computer to edit the config.ini file! Thanks to the embedded Local Web Server feature, you can easily save all your API keys in seconds via copy-paste by accessing the address (or scanning the QR code) provided by the app from your mobile phone or PC on the same Wi-Fi network!
Overlay Control via NRO App: Configuring Overlay settings used to be quite tedious. Now, thanks to the TranslateNX (.nro) application accessible from the HB menu, you can easily configure the app modes, API services, target languages, and interface options through a sleek menu. The settings you apply are instantly reflected in the Overlay running in the background.
