Sony - PlayStation (PCSX2) WIP

Last Updated: November 01, 2020

Background

PCSX2 is a PlayStation®2 emulator capable of running commercial games. It's an open source project that runs on Windows, Mac and Linux. Like its predecessor project PCSX, it is based on a PSEmu Pro spec plug-in architecture, separating several functions from the core emulator. PCSX2 requires a copy of the PS2 BIOS, which is not available for download from the developers, due to the copyright concerns and legal issues associated with it.

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. This allows you to play PS2 games on your PC, with many additional features and benefits.

PCSX2, 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 custom resolutions up to 8192×8192, anti-aliasing, and texture filtering.

Requirements

  • CPU:
    • Supports SSE2/AVX2
    • PassMark Single Thread Performance rating near or greater than 1600/2100
    • Two physical cores, with hyperthreading
    • Four physical cores, with or without hyperthreading
  • GPU:
    • Direct3D10/11 support
    • OpenGL 3.x/4.5 support
    • PassMark G3D Mark rating around 3000 (GeForce GTX 750)
    • 2 GB/4 GB Video Memory
  • RAM: 4GB/8GB

Attention

Because of the complex nature of emulation, even if you meet the recommended requirements there will be games that will NOT run at full speed due to emulation imperfection, floating point emulation differences, issues with emulator itself or other problems.

BIOS

Tip

Interesting fact: For maximum compatibility it is recommended that you use a BIOS image different than SCPH10000.BIN which is the oldest one

Tip

Transfer your BIOS files to the retroarch/system/PCSX2/bios/ directory.

There is no region locking so if you have a PAL BIOS on your PS2 you can still play NTSC games, and vice versa. You'll also need the BIOS dumped from your PS2. Unlike the PS2 PCSX2 does not implement region locking so if you have a PAL BIOS in your PS2 you can still play NTSC games, and vice versa.

Required or optional firmware files go in the frontend's system directory.

Compatibility

The current standalone development version is reported to be compatible with approximately 97.4% of 2,641 tested games as of August 2020. Compatibility means only that the game will not crash, lock up, or enter a loop; there can still be bugs, missing post-processing effects, textures, and shadows in many compatible games. This is especially the case in hardware mode; a slower software mode is available for bugs without workarounds. You can check compatibilirt list in here
