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](<https://en.wikipedia.org/wiki/Interpreter_(computing)>), [Recompilers](https://en.wikipedia.org/wiki/Dynamic_recompilation) and a [Virtual Machine](https://en.wikipedia.org/wiki/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.
# Project Details
## Project Details
The PCSX2 project has been running for more than ten 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. Visit the [PCSX2 compatibility list](https://pcsx2.net/compatibility-list.html) to check the latest compatibility status of games (with more than 2500 titles tested), or ask for help in the [official forums](https://forums.pcsx2.net/).

### Technical Notes
- You need the [Visual C++ 2019 x86 Redistributables](https://support.microsoft.com/en-us/help/2977003/) to run PCSX2.
- Windows XP and Direct3D9 support was dropped after stable release 1.4.0.
@ -46,7 +46,7 @@ _Note: Recommended GPU is based on 3x Internal, ~1080p resolution requirements.
- PCSX2 uses two CPU cores for emulation by default. A third core can be used via the MTVU speed hack, which is compatible with most games. This can be a significant speedup on CPUs with 3+ cores, but it may be a slowdown on GS-limited games (or on CPUs with fewer than 2 cores). Software renderers will then additionally use however many rendering threads it is set to and will need higher core counts to run efficiently.
- Requirements benchmarks are based on a statistic from the Passmark CPU bench marking software. When we say "STR", we are referring to Passmark's "Single Thread Rating" statistic. You can look up your CPU on [Passmark's website for CPUs](https://cpubenchmark.net) to see how it compares to PCSX2's requirements.

## About the PCSX2 Project
### What is the purpose of the PCSX2 project?
### Question 1: What is the purpose of the PCSX2 project
PCSX2 intends to emulate the PlayStation 2 console, allowing PS2 games to be played on a PC. This requires having an original PlayStation 2 console to supply a BIOS dump, and of course the original games to either be played directly off the disc, or be dumped and played as ISO images.
### Is PCSX2 open source?
### Question 2: Is PCSX2 open source
PCSX2 is open source, licensed under the GNU General Public License, v3. [Source code is kept on GitHub](https://github.com/pcsx2/pcsx2).
### How can I help the project?
### Question 3: How can I help the project
There are a number of ways to help the project, whether it be bug reporting, game patching, or even writing code for the emulator itself. Some examples:
* Want to make changes to emulator code? [Check out the issue tracker](https://github.com/PCSX2/pcsx2/issues), or [fork the PCSX2 repository and work on your own ideas](https://github.com/PCSX2/pcsx2).
* Want to patch games? [Check out the cheats and patches forum thread for inspiration](https://forums.pcsx2.net/Thread-Post-your-PCSX2-cheats-patches-here). There are other threads to find as well, [such as those dedicated to 60 FPS patches](https://forums.pcsx2.net/Thread-60-fps-codes) or [widescreen patches](https://forums.pcsx2.net/Thread-PCSX2-Widescreen-Game-Patches).
* Want to report bugs you have discovered in your games? [Head over to the Bug Reporting section of the PCSX2 forums](https://forums.pcsx2.net/Forum-Bug-reporting). Also check out our [GitHub issue guidelines](https://github.com/PCSX2/pcsx2/wiki/How-to-create-useful-and-valid-issues) for info on how we handle GitHub issues.
### Is PCSX2 ready to run out-of-the-box?
### Question 4: Is PCSX2 ready to run out-of-the-box
No, PCSX2 is not ready to run immediately. First, you must dump your PlayStation 2 console's BIOS using the BIOS dumper. The BIOS dumper is [available on the PCSX2 website](https://pcsx2.net/download/releases/tools.html).
After dumping your PlayStation 2 console's BIOS, you may launch PCSX2, step through the first time setup wizard, and then begin playing.

### How many CPU cores can PCSX2 use?
### Question 6: How many CPU cores can PCSX2 use
By default, PCSX2 uses two cores for emulation. Enabling the MTVU speedhack allows the PS2's VU1 coprocessor to run on a third core, which is safe for most games.
Software rendering in GSdx can be set to use as many or as few rendering threads as desired. We recommend using no more than 8, or the number of cores (including hyperthreads) that your CPU has, whichever is the lower number.
<div class="page"/> <!-- Because PDFs are terrible -->
### My CPU isn't being used 100%. Why?
### Question 7: Why isn't my CPU not using 100% of it's power
The CPU load as reported in software such as Windows' Task Manager is usually a *summation* of CPU usage, across *all* cores. Software can only use the resources of the individual CPU cores it is actually running on, and cannot "borrow" CPU time from other cores.
### Will SLI or Crossfire help with performance?
### Question 8: Will SLI or Crossfire help with performance
No. PCSX2 does not use or require SLI or Crossfire.
### How do I check if a game is playable?
### Question 9: How do I check if a game is playable

*While we encourage discussion about PS1 games and improving compatibility, bug reports are NOT being accepted for PS1 games. Any reports for PS1 games will be closed immediately as invalid.*
### My game doesn't work like it did in an earlier PCSX2 version. Why?
### Question 11: Why does my game not work like it did in an earlier PCSX2 version
One change to the emulator may fix one game, but cause problems for another. If the issue is severe and not fixable with different settings, you can always revert back to the last known PCSX2 version to work, and report the build number that broke the game. [Development builds](https://pcsx2.net/download/development.html) are very helpful for finding the exact change that caused a regression.
### Why is PCSX2 slow?
### Question 12: Why is PCSX2 slow
The PlayStation 2 is a complex console, and this complexity substantially raises the PC requirements to emulate it at full speed, accurately. [This forum thread](https://forums.pcsx2.net/Thread-Why-is-PCSX2-slow) helps explain some of the technical reasons behind it, and our current guidelines for PC requirements are listed above.
### Where do I get a PS2 BIOS?
### Question 13: Where do I get a PS2 BIOS
You have to dump the BIOS files from your PlayStation 2 console. There is a BIOS dumper tool [available on the PCSX2 website](https://pcsx2.net/download/releases/tools.html) to do this. If you need a guide, check the bottom of this FAQ for links to BIOS guides.

### Where do I get PS2 games?
### Question 14: Where do I get PS2 games
You can use games from your personal collection of discs, purchase them from local stores that resell old games, or look online at sites like eBay or Amazon.
### Can I use PS2 discs directly with PCSX2?
### Question 15: Can I use PS2 discs directly with PCSX2
Yes. However, some games have speed problems, because unlike the PS2 which would constantly keep the disc spinning, PCSX2 will not do the same to your PC's disc drive. It is recommended to instead dump your games to ISO images. ImgBurn is a popular software to do this with, and we recommend [installing ImgBurn by using Ninite](https://ninite.com) to avoid any issues with the ImgBurn installer.

### What is the difference between Full and Fast boot?
### Question 17: What is the difference between Full and Fast boot
Full boot will launch the PS2 BIOS, which will then launch the game. Some games need this for multi-language settings or times to work.
Fast boot will directly mount and launch the game without first launching the PS2 BIOS. Though slightly faster, this may cause some multi-language games to boot into the wrong language, or games that use the clock to give inaccurate times.

### I see framelimiter options. What are those? Will they boost my FPS?
### Question 21: Will framelimiter options increase my FPS
The framelimiter has a few options that allow you to alter the pacing of your games. This will directly affect the game's speed itself, NOT your framerate. Useful for speeding through sections of games, or slowing down for precision.
* Turbo (Tab): Bumps the framelimiter to 200%, allowing a game to run up to 2x faster than normal.
* Slowmo (Shift + Tab): Drops the framelimiter to 50%, restricting a game to 0.5x its normal speed.

Some settings are greyed out; these are advanced counters that should only be modified by those who understand the effects they have on a game's playback speed and frame pacing.
### What is the normal speed for a PlayStation 2 game?
### Question 22: What is the normal speed for a PlayStation 2 game
* NTSC games will play at 59.94 FPS
* PAL games will play at 50 FPS
* Keep in mind that there is a difference between the internal framerate (iFPS) and what PCSX2 shows as virtual framerate (vFPS).
These framerates are what the PlayStation 2 console would push to a real TV through its video cable. A game itself, typically, internally generates only half of those frames, and repeats frames to fill the gaps. This is why a "full speed" game may not "feel like 60 FPS". The console's "speed" (meaning AI, sound, physics, *everything*) is tied to the playback framerate, which is what PCSX2 reports as its "FPS".
### What are Gamefixes?
### Question 23: What are Gamefixes
Gamefixes are specialized fixes built into PCSX2 for specific games. Gamefixes mostly fix core emulation problems that would crash or soft lock a game, rather than graphical or performance issues. By default, the "System > Automatic Gamefixes" option is enabled, meaning any games that need gamefixes will have them automatically applied, regardless of what gamefix settings you have enabled.
Most games will not need gamefixes, however if your game is having issues, you can try manually enabling them in Emulation Settings.

### Are Speedhacks safe?
### Question 24: Are Speedhacks safe
As the name says, speedhacks are hacks to make things faster. They will speed up games, but risk causing stability problems or crashing some games. PCSX2 ships with some speedhacks enabled in the default "Safe" preset. This selection of speedhacks has been reviewed thoroughly and determined to be safe for nearly all games.
*Bug reports of issues caused by speedhacks will NOT be accepted, and will be immediately closed as invalid.*
### What are all these EE/IOP and VU options?
### Question 25: What are all these EE/IOP and VU options
The PS2 EE, IOP and VU processors are substantially different from a PC CPU and require different rounding and clamping modes to do math accurately. Most games work fine on the default options, but some games might need a different setting. You can check the [PCSX2 Wiki](https://wiki.pcsx2.net/Category:Games) to see if your game needs an alternate setting, or check the [PCSX2 Forums](https://forums.pcsx2.net/) to see if anyone else has posted about it there.
### What are PCSX2 plugins?
### Question 26: What are PCSX2 plugins
PCSX2 uses a plugin framework for various sections of the emulator. A plugin is a small, incomplete piece of software that, when plugged in to another piece of software, provides some sort of additional function. PCSX2 uses plugins for:
* Video (GSdx)
* Controls (Lilypad for Windows, OnePad for Linux)

Each plugin will have its own Plugin Settings menu, and can be found under the Config menu.
### Why is my sound garbled up?
### Question 27: Why is my sound garbled up
PCSX2's default audio playback mode is Timestretch, which will attempt to stretch sounds out when the emulator is unable to play at full speed, to fill the gaps in the sound playback and prevent even harsher stutters. If you are unable to get the game running at full speed or an acceptable speed where timestretching does not ruin the sound, you can try changing from Timestretch to Async, but this may break games.
### I have a controller here. Is it supported?
### Question 28: Is my controller supported
For Windows users running LilyPad, PCSX2 will ship with XInput bindings already created. This will automatically work with an Xbox One controller or any other XInput controller. Bindings can easily be made for DirectInput controllers, such as Xbox 360 controllers. PS3, PS4, or Switch Pro controllers should be set up using a compatibility software, such as Steam's Big Picture mode.
For Linux users running OnePad, PCSX2 will automatically detect and bind controls to any recognizable controller. If your controller is not automatically detected, you can try using Onepad Legacy to manually bind controls for it.
