PCSX2 PS2 Emulator
About the Project
Being almost as old as the console it is emulating, PCSX2 not only has a lot of history behind it, but a continually evolving future.
PCSX2 is a free and open-source PlayStation 2 (PS2) emulator. Its purpose is to emulate the PS2's hardware, using a combination of MIPS CPU Interpreters, Recompilers and a Virtual Machine which manages hardware states and PS2 system memory.
The project has been running for almost 20 years. Past versions could only run a few public domain game demos, but newer versions can run most games at full speed, including popular titles such as Final Fantasy X and Devil May Cry 3.
A significant majority of the official PS2 library is considered playable or perfect, with the remainder at least making it to the menus. For more information on compatibility, see here. [link]
PCSX2 allows you to play PS2 games on your PC, with many additional features and benefits. A few of those benefits include:
custom resolutions and upscaling
virtual and sharable memory cards
save-states
patching system
internal recorder to achieve lossless quality at full speed
