  • The video game: The Uni Games for the Commodore 64
  • The WiFi device, and its firmware
  • The smartphone application

The WiFi device consists of:

  • The firmware, that runs in the ESP8266 WiFi microcontroller
  • And the board:
UniJoystiCle WiFi device v0.4.1

Coded 100% in C++, the firmware uses a fast network protocol. Responsiveness is a top priority. Works with any ESP8266 module, and its range is more than 1000ft.


The UniJoystiCle smartphone application


This smartphone application reads the accelerometer data from the smartphone and converts it to joystick movements. It sends the data to the UniJoystiCle WiFi device in a fast and reliable way. Reliability a responsiveness is a top priority.


  • UniJoystiCle mode: Use this mode to play The Uni Games and any other game that can be played in rotating the joystick, like the Bike event in Summer Games II.
  • D-pad mode: To play the rest of the games, like Commando, Bruce Lee, etc.
  • Commando mode: Control both joysticks at the same time from just one Game Controller.
  • Gyruss mode: A novel way to play Gyruss and Gyruss-like video games.
  • Commodore Home mode:  For “Commodore Home“, home automation for the masses, not the classes
