PCSX2 is an open-source emulator that aims to recreate the hardware and functionality of the PlayStation 2 console. With almost 20 years of development, the project has come a long way, starting with only being able to run a few public domain game demos. However, newer versions of PCSX2 can now run most games at full speed, including popular titles like Final Fantasy X and Devil May Cry 3. Compatibility is generally high, with a majority of the official PS2 library considered playable or perfect. PCSX2 offers additional features such as custom resolutions, virtual memory cards, and save-states for an enhanced gaming experience on your PC.
