The PS2's MechaCon security chip has finally been cracked, 26 years after launch

Canadian modder DiscoStarslayer announced in mid-September 2026 that "one of the final secrets" of the PlayStation 2 has been broken open: the CXP102064 security chip, nicknamed MechaCon, found in the original 2000 model. After four years of work, its firmware can now be extracted through software, a first for a component that stayed opaque for more than a quarter of a century. The original announcement is on their X account.

MechaCon, short for Mechanics Controller, drives the console's optical drive but also handles several security functions: disc authentication, encryption of MagicGate memory cards and decryption of KELF files, the encrypted executables used by the system. It is one of the central locks of the PS2's security design, and its internal ROM had escaped all analysis until now.

Chemical decapping, optical dumps, then a software flaw

DiscoStarslayer first chemically removed the epoxy package to expose the silicon and study it up close. Those imperfect optical captures were then analysed by Libby, who found a flaw that bypasses the read protections and extracts the firmware cleanly, without a microscope. According to TechSpot, DiscoStarslayer has published metadata and hashes of the dumps obtained so far on GitHub, a detailed technical write-up is promised, and work continues on later revisions of the chip.

The expected benefits are mostly about hardware preservation: understanding this chip better can help modders and pave the way for better optical drive emulation (ODE) solutions for original consoles. Software emulation such as PCSX2, however, is unlikely to gain much. No consumer tool has been released at this stage, so there is nothing to download yet: for now this remains research work.
