Description

North Sea Helicopter was a flight simulation game for MSX1 published in 1985 by Aackosoft. One of the peculiarities of this game is that you need two 2 joysticks to control the flight (one of them could be the cursor keys, though).

The purpose of this project is to provide an adapter that lets you play the game using only one hand a Wii Nunchuck as a controller.

The project is built upon an Arduino Nano and can be totally built using off the shelf components.
