Gameport joystick USB adapter project.

A Teensy LC is used to read gameport joystick inputs.

Default USB interface code is modified so that the Teensy is detected as two separate joysticks.

Usage:

• Back up Teensyduino install hardware folder.
• Copy the hardware directory into the Teensyduino install folder, replacing the existing files.
• Open DualJoysticks.ino in the Arduino IDE.
• Select the new USB Type "Dual Joysticks".

Wiring diagram:

Additional analog and digital inputs can be connected to the Teensy as needed (simple gameport devices support 4 buttons and 4 axes each).
