NeoGeo to TG16 / PCE Adapter (Bliss-Box Bridge Universal Adapter)

How the NeoGeo to TG16 / PCE 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 Neo Geo / Famicom and your TG16 / PCE Console. The adapter will show up as both a 6 button or 2 button controller.  When the adapter detects the extra button being pressed, it sends the signal to the console. Some games will not understand that mode and will not work when these buttons are pressed.
