Infrared controllers

A few famiclones are equipped with infrared receiver and are paired with additional battery powered wireless joypad(s) with infrared transmitters. Most of them can be configured to work as P1/P2 or even execute special functions (console restart, power down). They use special proprietary chips to handle the communication, whose protocols are not compatible with each other.
