    PCSX2 is a free and open-source PlayStation 2 emulator for Windows, Linux, and macOS[5] that supports a wide range of PlayStation 2 video games with a high level of compatibility and functionality. Although PCSX2 can closely mirror the original gameplay experience on the PlayStation 2, PCSX2 supports a number of improvements over gameplay on a traditional PlayStation 2, such as the ability to use resolutions up to 8 times larger than native, anti-aliasing and texture filtering.

    Background

    PCSX2, like its predecessor project

    FireWire (i.LINK) ports. Different plug-ins may produce different results in both compatibility and performance. Additionally, PCSX2 requires a genuine copy of the PS2 BIOS, which is not available for download from the developers due to copyright-related legal issues. Since September 2016, PCSX2 is partially compatible with PlayStation games.[6]

    The main bottleneck in PS2 emulation is emulating the Emotion Engine multi-processor on the PC x86 architecture. Although each processor can be emulated well independently, accurately synchronizing them and emulating the console's timing is difficult.[7]

    Development

    Development of PCSX2 was started in 2001 by programmers who go by the names Linuzappz and Shadow, who were programmers for the PlayStation emulator PCSX-Reloaded. Other programmers later joined the team, and they were eventually able to get some PS2 games to the loading screen. The team then started working on the difficult task of emulating the PlayStation 2's BIOS; they got it to run, although it was slow and graphically distorted. Version 0.9.1 was released in July 2006.

    From 2007 to 2011, developers worked on Netplay and speed improvements.[8] PCSX2 0.9.8 was released in May 2011 and featured an overhauled GUI written with wxWidgets, that improved compatibility for Linux and newer Windows operating systems. In December 2022, PCSX2 was overhauled to remove all WxWidgets elements. The project has used QT since. The addition of a new VU recompiler brought better compatibility, a memory card editor, an overhaul of the SPU2-X audio plug-in, and numerous other improvements.[9] As of Apple is deprecating support for OpenGL and OpenCL with the release of macOS 10.14. PCSX2 officially stopped developing new versions of PCSX2 for macOS version.

    As of November 2021, 97% of PlayStation 2 games are considered "playable" on the emulator, meaning they can be played largely but not entirely free of slight issues.[10] 22 games are considered "perfect" – free of bugs – and all but one at least boot to the menu screen.[10]

    In 2022, PCSX2 added support for the

    Xbox Series X/S known as XBSX2.[13]

    Features

    PCSX2 supports

    Cheat codes
    are supported via the use of PNACH patching files.

    Plug-ins

    PCSX2 makes use of plug-ins as a means of modularizing development efforts among the separate components (subsystems) of the emulated PlayStation 2 hardware. For instance, video plug-ins are utilized by PCSX2 to render images to the screen and emulate the graphics hardware of the PlayStation 2, whereas sound plug-ins emulate the sound hardware of the PlayStation 2. Not only does this allow different developers to focus their efforts on one aspect of the PlayStation 2 hardware, this also allows users that have a system configuration that does not yield good results with one plug-in to attempt to try another to see if they have better results.

    A list of several plug-ins follows:

    Name Subsystem Notes
    GSdx Video The fastest, most accurate graphics plug-in. Requires Direct3D or OpenGL support and optionally uses a GPU. GSdx plug-in is compatible with PSX emulators but is limited to software rendering with them. There also exists an unofficial ToCAEDIT[14] version and the GSdx-Cutie version.[15]
    GSdx FX Video Post-processing shader pack for GSdx plugin.
    ZZogl Video A less optimized graphics plug-in that uses Open GL. Compatible with Linux and Windows. This plugin is fork of ZeroGS KOSMOS plugin.
    SPU2-X Audio The most accurate sound plug-in.
    SSSPSX Pad Input A simple input plug-in.
    LilyPad Input An advanced input plug-in that supports keyboards, mice, and controllers.
    Nuvee Input An input plug-in that supports lightguns and USB mice.
    TwinPad Input Another keyboard and mouse plug-in.
    XPad Input An Xbox 360 controller input plug-in.
    CDVD Optical A simple optical media plug-in that runs games from optical discs.
    Linuz ISO CDVD Optical A plug-in which has the ability to compress
    ISO images
    .
    Dev9 Hard drive Handles PS2 hard disk drive and Ethernet emulation.
    MegaDev9 Hard drive A more advanced version of Dev9. Currently, it only partially emulates the PS2 hard drive.
    Netplay Netplay A plug-in which allows certain games to be playable multiplayer over the Internet.

    As of v1.7.0-dev-1420[16] PCSX2 has merged all functionality into the core emulator, eliminating the concept of plugins as well as releasing 64-bit variants.

    The list of plugins that have been merged are listed below:

    • GS: GSDX
    • SPU: SPU2
    • PAD: Lillypad (Windows) | Onepad (Linux)
    • DEV9: Dev9Gigaherz
    • CDVD: CDVDGigaherz

    Graphical Improvements (GSdx Plugin)

    The GSdx plug-in offers a variety of image quality improvements over the original PlayStation 2 hardware, such as:

    Hardware requirements are largely game-dependent. Due to the demanding nature of emulation, PCSX2 is much more likely to perform well with modern mid-range to high-end hardware, with lower-end systems likely to experience less than full performance. The performance bottleneck in most cases is the

    video cards
    . As computer hardware has continued to advance with time, the likelihood of performance issues with PCSX2 has experienced a corresponding decrease.

    Reception

    PCSX2 has been very well received. Matthew Humphries of

    Tom's Guide mentioned PCSX2 in his Best PlayStation Emulators for PCs article, saying, "When it comes to stable, playable Playstation 2 emulation, PCSX2 is pretty much the best game in town at the moment."[23]
