Nintendo to Nintendo Adapter (Bliss-Box Bridge Universal Adapter)

How the Nintendo to Nintendo Adapter Works

The Bliss-Box Bridge Adapter uses a communication protocol called LLAPI(Low-Level API). LLAPI was originally developed for internal Bliss-Box products, but it is now fully open-source for the community. All modern Bliss-Box adapters support LLAPI, allowing the Bridge to read the controller’s raw data and translate it into the format required by the output device—acting just like a native controller.

Once connected, the Bridge communicates seamlessly between your Nintendo controller and console.
