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.
