## About 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.

*Note: Recommended GPU is based on 3x Internal, ~1080p resolution requirements. Higher resolutions will require stronger cards; 6x Internal, ~4K resolution will require a [PassMark G3D Mark](https://www.videocardbenchmark.net/high_end_gpus.html) rating around 12000 (GeForce GTX 1070 Ti). Just like CPU requirements, this is also highly game dependent. A quick reference for GPU **intensive games**: [Wiki](https://wiki.pcsx2.net/Category:GPU_intensive_games)*
### Question 6: 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.

### Question 7: Why isn't my CPU not using 100% of it's power
### Question 7: Why isn't my CPU not using 100% of its 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.
### Question 8: 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.
### Question 9: How do I check if a game is playable
### Question 9: How do I check if a game is playable?
The PCSX2 website has a [compatibility list](https://pcsx2.net/compatibility-list.html) with every game that has been tested.
### Question 10: Do PS1 (PSX) games work on PCSX2
### Question 10: Do PS1 (PSX) games work on PCSX2?
#### If you want to enjoy your PS1 games without issues
No, they will not work. Please use a proper PS1 emulator, such as Mednafen.
#### If you want to enjoy your PS1 games without issues:
No, they will not work without issues. Please use a proper PS1 emulator, such as Duckstation or Mednafen.
#### If you are a tinkerer and like to break things
PS1 games may work on PCSX2, but compatibility is very limited. Specific settings are often required to get a game to boot, and there are other universal problems including missing and pitch shifted audio, and severe FMV corruption. A [forum thread for PS1 compatibility](https://forums.pcsx2.net/Thread-PSX-Mode-Unofficial-Compatibility-List) is tracking some fixes and compatibility reports.

*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.*
### 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.

### Question 13: 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.

### Question 14: 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.
### Question 15: 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.

### 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.
### Question 17: What is Fast Boot?
Normally, PCSX2 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.
Fast Boot will directly mount and launch the game without first launching the PS2 BIOS. On versions 1.6 and below, this may cause some multi-language games to boot into the wrong language.

### 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.
### 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, and can be 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.
* Framelimiter Disabled (F4): Completely disables the framelimiter. The game will run as fast as your PC can push it.
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.

### Question 22: 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".
### Question 23: 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.

### Question 24: 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.*
### Question 25: 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.

### Question 26: What are PCSX2 plugins?
Older versions of PCSX2 used 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 used to use plugins for:
* Video (GSdx)
* Controls (Lilypad for Windows, OnePad for Linux)
* USB (No plugin included)
Each plugin will have its own Plugin Settings menu, and can be found under the Config menu.
In newer versions, these have been merged into the main emulator, and there is no longer a way to load external plugins.
### Question 27: 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.
### 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.
