The Dual Turbo Wireless Remote System is a set of 2 wireless 3-button control pads for the Sega Mega Drive manufactured by Acclaim. It also includes a receiver which connects to the front of the Mega Drive System across both controller ports. The controllers communicate wirelessly with the system via an infrared signal which requires line of sight, but has a fairly large arc much like a remote control for a television.
In addition to all standard buttons found on any Mega Drive controller, the Dual Turbo controllers feature 3 additional buttons. A Turbo button which can be used to set the turbo function independently on the 3 face buttons, a Slow button which can be used to put your game into slow motion, and the power button for the controller.
