Breaking the console: a brief history of video game security (sergioprado.blog)

The article traces how video game console security evolved from early systems with virtually no protections to later attempts at enforcing authenticity through hardware lockout chips, optical-disc authentication, and finally cryptographic code-signing. It highlights recurring patterns—security measures based on obscurity or media checks eventually being reverse-engineered or bypassed—citing examples like the NES 10NES/CIC lockout, PlayStation modchips and disc swap attacks, and the Xbox’s cryptographic boot-chain followed by “softmod” exploits via vulnerable save-file parsers and memory-safety bugs. The author concludes that while threat models differ across devices, many of the same underlying security challenges reappear across decades.
