Original Sony PlayStation 2 security chip 'broken wide open' after 26 years
3 hours ago
- The security chip in the original PlayStation 2, the MechaCon, has been reverse-engineered after 26 years and four years of dedicated work.
- The breakthrough will benefit hardware preservation, repair, and emulation projects.
- The chip controlled the PS2's optical drive and flash mechanics, and was involved in security features like Magic Gate memory card and KELF file decryption.
- Reverse engineering involved chemical decapping to expose the chip die, then microscopic analysis and optical dumping.
- An exploit was discovered during hacking, allowing software-based extraction of chip data.
- This achievement improves emulation, homebrew development, and could enable replacing aging PS2 optical drives.
- The MechaCon was also used in arcade machines like Namco System 246/256 and Konami Python 1.
