PlayStation 2 MechaCon security chip cracked after 26 years

After 26 years, the final hardware security mystery of the PlayStation 2 has been solved. Developer DiscoStarslayer, assisted by coder Libby, successfully extracted the firmware from the MechaCon chip (CXP102064).

This component, integrated into original 1999 models, manages the console's optical drive, including laser focusing, motor control, and disc drawer operations. It also handles critical security functions such as region locking and data authentication.

Because the chip's code was embedded in a mask ROM, traditional readout methods were impossible. The breakthrough required intensive reverse engineering, including decapping—a process where the chip's casing is chemically dissolved to expose the silicon. By mapping the circuits under a microscope, the team identified a software vulnerability that allowed them to dump the data. This achievement is considered a significant milestone for the long-term preservation of video game history.
