A couple of months ago we shared a video by JackTech, which explored in some detail how the Game Boy CPU works. It was part one in a 'hardware autopsy' series that aims to unpick and explain how the iconic portable device operates, providing some insight into how humble technology was used in clever ways.

It's an intriguing watch - you can check it out below.
