This device is a product design I work for a while. It is a replacement of a joystick of old-school 8-bits computer named Commodore 64 ( also compatible with Atari and Amiga computers of time). With arrow keys layout, it's easier to use than the joysticks.
The thing that makes this special for me, is that I also made the electronic assembly and design of it too.
