This is a Rare Development Prototype for the Atari/MasterSystem/Genesis to USB Adapter. It was developed in coordination with Raphael Assenat of Quebec. This adapter can power the Sega Genesis Multitap.It can power up to four Sega Genesis six button controllers at once.

Important Details:

To a Typical PC, this prototype appears to be a single 8 Axis, 32 Button Controller. This is intended behavior.
You get the genuine Sega Team Play Adapter and four Controllers. It can be detached from the adapter and used with a real Sega Genesis. Works on Windows PCs and Linux PCs. Whatever game or emulator you use with this needs to support mapping individual buttons and axis.

This is a prototype as it was the first iteration of the device, enclosed in a Radio Shack Project case and is likely to function differently than the production model.
