It seems that someone wasn’t content with just playing the original Zelda or Zelda II on a regular NES. This fan decided to show his love for the franchises oldest games by modding his NES and creating both a custom controller and a container to hold it.
When the container is opened it lights up with a phrase anyone who has played the original game should be familiar with. The controller has the Hylian crest on it, and the console itself has a Triforce on the top that lights up when the console is turned on. For those who want to see it in action, there’s a short video just below you can watch.
