Striker Stereo Control Pad
From Sega Retro
The Striker Stereo Control Pad is a third-party Sega Mega Drive controller manufactured by Beeshu. It improves on the standard Mega Drive controller in many ways, having turbo buttons, an 8-foot lead, a mini joystick replacing the D-Pad and a stereo headphone socket.
The peripheral had to be discontinued after it was identified as a choking hazard.
