The ColecoVision Roller Controller was a trackball controller that plugged into the controller ports of the ColecoVision while the ColecoVision controllers plugged into the controller ports of the unit itself. It allowed for trackball control for all ColecoVision games that normally used the standard controller's control stick, though some games were specifically designed for use with the Roller Controller's trackball.
