USB arcade joystick electronics enclosure

Playing games on emulators is usually bound to using arrow keys on the computer keyboard or an analog PC joypad. This ruins all the fun. The right way to do this is of course using a real arcade joystick. This blog http://ezcontents.org/usb-arcade-joystick describes how to use a simple board to connect your old DB9 port arcade joystick. This design creates a nice enclosure for the electronic parts and the connectors.
