PCSX2 is a PlayStation 2 emulator for Windows and Linux, started by the same team that brought you PCSX (a Sony PlayStation 1 emulator).
The PCSX2 project attempts to allow PS2 code to be executed on your computer, thus meaning you can put a PS2 DVD or CD into your computers drive, and boot it up!
The project has been running for a little over four years now, and since it's initial release has grown in compatibility. From initially just being able to run a few public domain demos, it's current state enables many games to boot and actually go in game, such as the 'famous' Final Fantasy X or Devil May Cry 3.
PCSX2 was initially started by shadow, linuzappz and saqib, but since then more coders have joined the team, bringing their unique expertise with them. The development team now consists of:
auMatt: Works on the CDVD and main functions of PCSX2. Florin: Coder for many of PCSX2's key aspects. GoldFinger: The man behind PCSX2's first recompiler. Linuzappz: Previous project leader and responsible for vast amounts of PCSX2's code. Refraction: Working on IOP timings and general fixes. Saqib: The project leader, GS developer, IPU coder, and developer of numerous other aspects of PCSX2. Shadow: Second in command, works on all aspects of the project. Zerofrog: Re-writing the recompiler, general fixes and new features.
