Intellivision controllers

Intellivision I and II are singular machines of their time! Using a full blast keypad, disc gamepad and multi trigger anti-ergonomic controller is the least we can say. It was a challenge to implement!

-update-
Latest version decode the keypad  but also send a raw copy of the pin scanning to the emulator. JziIntv was the first emulator to implement this feature. It keeps all special key combination and easter eggs possible!
