The first large-frame models of PlayStation 2 CXP102064MechaCon The contents of the chip could be read after approximately four years of reverse engineering. On September 13, researcher DiscoStarslayer announced the process, which starts with physically examining the chip and extends to extracting data through software; He stated that the vulnerability found by his colleague named Libby provided the final step. This development does not mean that the security of all PS2 models has suddenly disappeared.
Researcher’s statementexplains that first the chip package is opened with a chemical method, and then the data on the silicon is read with a microscope. This optical dump helped find the vulnerability that allowed content extraction through software. Tom’s Hardware’s technical report also identifies the focus of the work as the specific MechaCon variant from the first large-case PS2 releases.
In addition to managing the mechanical work of the console’s optical drive, MechaCon takes part in disk and some file security processes. Therefore, access to the chip’s code is important for those who want to repair old hardware, understand its behavior and improve emulation accuracy. However, dumping a single chip version does not prove that subsequent PS2 Slim models run the same software.
Moreover, reading the code does not mean that every copy of the game will work without any additional processing or that the optical drive can be emulated immediately. A developer who stated that he participated in the study explains in Tom’s Hardware’s discussion that the existing dumps alone are not enough to build a full optical drive emulator. There were already other software-based homebrews on the PS2; The contribution of this research is that it makes the inner workings of early MechaCon visible.
MechaCon research could contribute to preserving legacy hardware
The security controllers used in different production periods of the PlayStation 2 are not the same. The research focuses particularly on CXP102064 in the early years; It would be wrong to directly generalize the results for subsequent “Dragon” MechaCon versions. Conversely, understanding the code of early hardware could provide new technical data to examine failing optical drives and outdated peripherals of still-working consoles.
The developer emphasizes that the four-year work is not just a search for a software vulnerability. Physical unpacking and optical reading were required in the first stage; Clues in this data then paved the way for transcription through software. This order is important because the phrase “chip is broken” sometimes directly creates the impression that all protections have been removed. The concrete achievement announced is the acquisition of the contents of the particular chip.
How researchers will use the data in hardware protection and low-level emulation projects will become clear with future studies. For now, there is no automatic change to daily usage for PS2 owners; The published result provides a new starting point for the technical documentation of the older console in particular.
Another outcome of such studies could be the documentation of the behavior of original parts that are no longer produced. However, a concrete repair tool, a new emulator version or a user-oriented usage method has not been announced. The practical contribution of the resulting casting will be understood with subsequent independent projects.
