PlayStation 2
A home video game console released by Sony in 2000 and one of the best-selling consoles in history. It features DVD playback capability and a comprehensive hardware security architecture.
Timeline (last 90 days)
The Linux feature on the PS2 and PS1 was never removed.
An unmodified North American PS2 cannot run the Japanese PS2 Linux kit because Sony applied region locking to the discs.
FreeDVDBoot is a softmod tool that exploits a vulnerability in the PS2 DVD player, triggering a buffer overflow through carefully crafted DVD video files to execute arbitrary code on an unmodified console.
FreeMCBoot is a homebrew boot environment installed on a memory card that allows the console to load unofficial programs from the memory card at startup.
The principle of the ESR patch is to modify the video identification bytes embedded in an ISO image so that the PS2 system misidentifies it as a video disc and thus allows it to boot, after which a bootloader hijacks the execution flow to load the real Linux kernel.
The PS2 firmware sends a proprietary ATA command to the hard drive, and if the drive's response does not meet expectations it is rejected; official hard drives know how to respond correctly, while third-party hard drives do not.
The National Center for Supercomputing Applications (NCSA) once built a computing cluster using 70 PS2s.
It was rumored that Saddam's regime once imported about 4,000 PS2s for similar computing purposes, but this was never confirmed.
Sony released the official PS2 Linux Kit in 2002, allowing players to install a complete Linux operating system on the PlayStation 2.
Precisely mapping the behavior of the PS2's heterogeneous multi-core architecture to WebAssembly's single-threaded or limited multi-threaded model is the core technical challenge in statically recompiling PS2 games.
