Back in the '90s, the Sega Saturn was the most powerful video games console on the market. If the Sony PlayStation was a car, the Saturn was a military tank. But it was an expensive over-engineered machine and it failed to make an impact in the gaming market. So complex was the Saturn that some of its internal functions remained a mystery 20 years on, particularly its elusive digital rights management (DRM) system.

In July, hacker and academic Dr James Laird-Wah managed to crack the DRM and uncover its inner workings. He went through the painstaking process in excruciating detail at hacker conference Ruxcon 2016. Laird-Wah's findings could potentially save the rising number of Sega Saturn consoles with dying CD readers.
