The '''[[wikipedia:PlayStation_2|PlayStation 2]]''' (PS2) is a sixth-generation console released by Sony on October 26, 2000, and it was retailed for {{Inflation|USD|299.99|2000}}. It has the Emotion Engine CPU based on the MIPS R5900 at 300 MHz with 32 MBs of RDRAM system memory and 4 MBs of eDRAM (VRAM). Its GPU was a custom Graphics Synthesizer, which ran at 150 MHz. It became the highest-selling console of all time, with over 155 million units sold. 

Announced in 1999, Sony began developing the console after the immense success of the PS1. The PS2 offered backward-compatibility for the PS1 DualShock controller, as well as its games.<ref name="wikipedia">[https://en.wikipedia.org/wiki/PlayStation_2 PlayStation 2 at Wikipedia]</ref>

The PlayStation 2 received widespread critical acclaim upon release. A total of over 4,000 game titles were released worldwide, with over 1.5 billion copies sold. In 2004, Sony released a smaller, lighter revision of the console known as the PS2 Slim. Even after the release of its successor, the PlayStation 3, it remained popular well into the seventh generation. It continued to be produced until 2013 when Sony finally announced that it had been discontinued after over twelve years of production, one of the longest lifespans of any video game console. By the end of its life, two new games were launched posthumously for the console.<ref name="wikipedia" />

===Comparisons===
;[[PCSX2]]:[[History_of_emulation#PlayStation_2|Started sometime in mid 2001]], with its first release on March 23, 2002. It was the first PS2 emulator to boot games on Dec 19, 2002. Succeeding their earlier PCSX [[PlayStation_emulators|PlayStation emulator]], PCSX2 dedicated its development to faithfully replicating the PS2 experience. The years haven't dimmed its shine thanks to the continuous improvements in accuracy, compatibility, and performance. In the last years, PCSX2 nightly builds boast a sleek, modern QT GUI and a pluginless design, eliminating the headaches of plugin configuration and making all features readily available. Just grab the original system firmware and you're ready to relive your PS2 memories. PCSX2 also has lots of new modern [[#Enhancements|enhancements]] built-in (one of the best emulators when it comes to enhancement capabilities, similar to Dolphin, Flycast, BigPEmu, PPSSPP and DuckStation) and supports some of the [[#Hardware_features_and_accessories|hardware features, peripherals]] of the PlayStation 2.

:PCSX2 has great compatibility, and it is capable of playing most titles without any major glitches however [https://wiki.pcsx2.net/Category:Software_rendering_only_games some titles still need software rendering] to run without any major graphical issues. For checking if your games work and any fixes, tweaks, or settings, check these sources;
::*[https://raw.githubusercontent.com/PCSX2/pcsx2/master/bin/resources/GameIndex.yaml PCSX2 GameDB] (GameIndex)
::*[http://wiki.pcsx2.net/index.php/Main_Page PCSX2 Wiki] (Note that the wiki can contain outdated information. It is encouraged to do personal testing and contribute to the wiki)
::*[https://pcsx2.net/compat/ Official Compatibility List]
::*[https://github.com/PCSX2/pcsx2/issues PCSX2 github issues]

:;[[AetherSX2]]:A closed-source freeware emulator partially forked from PCSX2. It's designed to be optimal for ARM-based platforms, primarily those running Android. 
::It has multiple versions; The latest google play version which contains ads while an ad free Alpha version can be downloaded directly from the AetherSX2 website. Development was stopped due to various dramas. Using NetherSX2 patches heavily recommended.

;[[Play!]]:Development is almost all done by the single maintainer jpd002. Also, unlike PCSX2 it's supports [https://www.youtube.com/@emugamer2610/search?query=246%2F256 Namco System 2x6] variations and it has a playable Android and iOS port.

;[https://github.com/PSI-Rockin/DobieStation/ DobieStation]:Many titles can go ingame, focused on [[Emulation_accuracy|accuracy]], and therefore inherently slower than Play! or PCSX2.

;[[sourceforge:projects/hpsx64/|HPS2x64]]:Can also run quite a few commercial games, but probably less so, and at slower speeds than Play!. It also emulates and focuses more on [[PlayStation emulators|PlayStation]] emulation. There is also a [https://github.com/Zero3K/hpsx64 mirror] that has fixes done to it.

;[[DamonPS2]]:Closed-source payware/malware emulator only for Android, illegally based on [[PCSX2]], [[Play!]] and [[PPSSPP]]. '''It can hardly run any games''' and behaves very much like virus software. '''It is the worst PS2 emulator and as such, it is NOT recommended under any circumstance'''. DamonPS2 uses unnecessary DRM, making the emulator useless without an internet connection.

Use [[#DVD_player|these dump files]] which will affect [https://github.com/F0bes/biosdrain/issues/5 IPL’s console model number recognition positively] when used with latest PCSX2 builds.

===PlayStation Backwards Compatibility===
[[Wikipedia:List_of_PlayStation_games_incompatible_with_PlayStation_2]]
*PCSX2: [https://forums.pcsx2.net/Thread-PSX-Mode-Unofficial-Compatibility-List Partially compatible]. '''Only PS2 BIOSes from original fat PS2's will be able to run PSX games'''. Due to the IOP changes Sony made on the slims, they simply won't run PSX games in PCSX2 right now.
*Play!: Play has [https://github.com/jpd002/Play-/issues/327 no support for backwards compatibility].
*[[Official_emulators#Sony|<abbr title="ps2_emu for PlayStation 3.">Official Sony emulators</abbr>]]: PlayStation 3's [[Official_emulators#PlayStation_2|ps2_emu]] firmware used for PlayStation 2 backwards compatibility and [[Official_emulators#PlayStation|ps1_emu]] for PlayStation backwards compatibility. See [[Official_emulators]] for more information.

===PocketStation communication===
[[Wikipedia:PocketStation#Compatible_games]]
*PCSX2: [https://forums.pcsx2.net/Thread-PSX-Mode-Unofficial-Compatibility-List PSX memory cards will appear in the PS2 BIOS as Pocketstation devices]. This is due to a hack that was required for some Pocketstation compatible games to detect memory cards, and is strictly a visual side-effect with no performance or compatibility issues.
*[[Official_emulators#Sony|<abbr title="ps2_emu for PlayStation 3.">Official Sony emulators</abbr>]]: [[PocketStation_emulators|PocketStation]] communication with PlayStation 3 system is possible with a "memory card adaptor for PlayStation 3".

===PSP communication===
[https://old.reddit.com/r/ps2/comments/atwi34/list_of_ps2_games_with_psp_connectivity/ List of PlayStation 2 games with PSP connectivity]

*PCSX2 [https://github.com/PCSX2/pcsx2/issues/3527 has no support for PSP communication at the moment].

This feature shouldn't be confused with PSP-PlayStation 3 direct communication.

===i.LINK===
S400 Firewire cable for connecting two PS2 console together and play split screen on separate TVs. Not all games supported it and it was dropped in later versions of the console. Currently no emulators support it.<br/>

*[[Wikipedia:List_of_PlayStation_2_online_games#i.Link_Games|i.Link Games]]

===Pressure Sensitive Buttons===
The DualShock 2 has all buttons and sticks with variable pressure states (except for L3, R3, Start, & Select). 

Most PS2 games do not require this feature, instead preferring to use the triggers and/or joysticks for pressure-sensitive actions (e.g., sneaking past the sleeping dog in ''Chulip''), but a select few do. Some examples include:
* All three attack buttons in ''The Bouncer'' precipitate different attacks based on whether the press is light, medium, or strong. The same goes for the musical game ''Mad Maestro''.
* ''Star Ocean 3'' has a musical item that plays different melodies depending on pressure, and they're required for progressing.

Games requiring variable trigger pressure need physical controllers with analog sticks, which is fortunately a standard feature of most half-decent controllers on the market. Pressure-sensitive ''face buttons'', on the other hand, haven't appeared on any standard PlayStation controllers since the DualShock 3 (DualShock 4 removed this feature), and it's very rare for a third-party controller to feature them either.

* [https://www.pcgamingwiki.com/wiki/List_of_games_that_support_Pressure-Sensitive_Face_Buttons#PlayStation_2_Emulation List of games that support Pressure-Sensitive Face Buttons on PlayStation 2]

;::PCSX2 wxWidgets builds guide
::::To know if your controller supports it, open the LilyPad plugin settings by going to the PCSX2 menu and selecting "Config", "Controllers (PAD)", and "Plugin Settings". At the LilyPad plugin popup, select your gamepad from the list of detected controllers in the "Device Diagnostics" box in the lower left, then click the "Test Device" button. A small popup window will appear, showing a list of all the gamepad's buttons and their current state. 0.000 = indicates unpressed, 1.000 = indicates fully depressed. Roll either analog stick around. See how the values change from 0.000 to 0.xyz, with the .xyz values shifting incrementally. These changing .xyz values show how the plugin detects different changes in angle as you move the analog stick around. Now press any of the buttons normally used by games, i.e., the triangle/square/cross/circle buttons.  See how the values immediately shift from 0.000 (unpressed) directly to 1.000 (pressed) If your gamepad really has pressure-sensitive buttons, you'll see gradual 0.xyz changes as you slowly press each button, just like the different changes in angle as you move the analog sticks around. If the buttons change from 0.000 directly to 1.000, that proves your gamepad buttons aren't pressure-sensitive and are merely tracking the pressed/unpressed state. The solution would be to either buy an official DualShock 2 or 3 controller (The Original Xbox Controller is not supported) and use an appropriate 3rd party driver such as [[SCP Driver Package]].

:::Also you can map the button to a rarely used trigger/stick in LilyPad;
::::Open the gamepad plugin configuration and choosing a rarely used key - for example, the lower shoulder button L2 - and remapping it to the circle button and setting the sensitivity to 0.500 or thereabouts. In the game, merely use the remapped L2@circle button to deliver "light" tap/hold tunes, while the regular circle button can be used normally to deliver "hard" tap/hold tunes.

===DVD player===
[[File:PCSX2_MagicGate_fork_-_DVD-Video_menu_demonstration.jpeg|thumb|298px|PCSX2 MagicGate fork - DVD-Video menu demonstration]]
PS2's DVD player was a versatile and powerful feature for its time, it supports PlayStation2 format DVD-ROM, PlayStation 2 and [https://www.steamgifts.com/discussion/91HAP/what-disc-types-are-compactible-with-ps2 PlayStation 1 format CD-ROM] and offering great playback compatibility for the most common disc formats. While it lacked official support for DVD Audio and VCD, its ability to play DVD Video and Audio CDs, along with additional options like progressive scan and upscaling, made it a compelling choice for entertainment and multimedia playback. Also [[Home_Media_Player#Interactive_media|Interactive film/movie]] formats like DVDi and DVDPG supported. Lastly, PlayStation 2 supports both DVD5 (single-layer, 4.7 GB) and DVD9 (dual-layer, 8.5 GB) DVD-ROM discs. However, some users report encountering issues with DVD9 discs, particularly on older PS2 FAT models.[https://old.reddit.com/r/ps2/comments/xc04yl/can_the_fat_ps2_play_dvd9_discs/].

*PCSX2 has CD-ROM and DVD-ROM support so you can boot your game directly from your physical discs ([https://youtu.be/DJkl4FrDgLw demonstration]), however there are no DVD-Video and Audio CD support at the moment. See [https://github.com/PCSX2/pcsx2/issues/1981 DVD-Video compatibility] and [https://github.com/PCSX2/pcsx2/issues/4880 CDRWIN's BIN/CUE format, Audio CD support] feature request pages for more information.

*PlayStation 3 has no PlayStation 2 DVD player interface support because: no emulation process needed to handle DVD-Video. PlayStation 3 already features a slot-loading 2× speed Blu-ray Disc drive for BD-ROM, PlayStation2 format DVD-ROM, PlayStation 2 and PlayStation 1 format CD-ROM, Blu-ray Disc Video, DVD-Video, and Audio CDs. Having said that there is no support for VCDs for PlayStation 3 just like PlayStation 2.

===LAN tunelling===
:Offline multiplayer gaming on the PS2 home console over a LAN (local area network) multiplayer games,  just like System Link for [[Microsoft|XBOX systems]]. Over time, most [[Preservation_projects#Private_Game_Servers|game servers have been shut down]]. However, [[Preservation_projects#LAN_Tunneling_Programs|computer programs such as XBSlink, SVDL and XLink Kai]] allow users to play multiplayer for LAN supported PS2 games by using a network configuration that simulates a worldwide LAN.

===Accessories===

====Hard Disk Drive====
:[[Wikipedia:PlayStation_2_Expansion_Bay#Hard_Disk_Drive|Wikipedia - PlayStation 2 Hard Disk Drive and compatible titles]]
The PS2 Hard Disk Drive was an official peripheral released by Sony for the PlayStation 2 console. It launched in July 2001 in Japan and March 2004 in North America. The HDD required the Network Adapter to function, because of this it's important to know that not all PS2 models supported the HDD. Only the fat models (SCPH-30000 to SCPH-50000 series) had the Expansion Bay needed to connect the Network Adapter for Hard Drive.

PlayStation 2 Hard Drive offered;
*Ability to install and run Linux using [[Wikipedia:Linux_for_PlayStation_2|Linux for PlayStation 2 disc]]
*Extra network functionalities, such as: accessing online content (game demos and updates etc) from platforms like [[Preservation_projects#Private_Platform_Servers|PlayStation Broadband Navigator]] and [[Preservation_projects#Private_Platform_Servers|PlayOnline Viewer]]. Also [[Wikipedia:PlayStation_2_Expansion_Bay#North_American_releases_with_HDD_support|some of the titles]] such as: [https://remywiki.com/CS_pnm_Puzzle_Dama Pop'n Music Puzzle-dama Online] requires an installation to the PS2 HDD in order to play, as the game boots from the PlayStation Broadband Navigator or HDD Utility Disc, and does not require the game disc or a registration code.

As stated in the [[Early_Online_Services#Network_Adaptor_.28PS2.29|Network Adapter]] section, slim models comes with Ethernet functionality of the Network Adaptor has been integrated onto the motherboard, because of this slim models have no Hard Drive support.

====EyeToy====
The [[wikipedia:EyeToy|EyeToy]] is a device similar to a camera or a webcam. It's an accessory developed by Sony and manufactured by Logitech. It is used in some PS2 games to interact physically through motion detection. The EyeToy device can be emulated with [[PCSX2]]. It also works natively with the [[PlayStation_3_emulators|PlayStation 3]].

====DVD Remote Control====
:[[Wikipedia:PlayStation_2_accessories#DVD_Remote_Control|Wikipedia: DVD Remote Control]]
You can even play games with this remote controller other than multimedia functionalities, there's a setting in the System Config that says 'Remote Gameplay Function', set this to on for playing games with this peripheral.

===USB plugin for wxWidgets builds===
Some PS2 games use a USB adapter with a module/dongle consisting of two jack ports for microphones. [[wikipedia:List_of_songs_in_SingStar_games_(PlayStation_2)|Installments]] from the [[wikipedia:SingStar|''SingStar'']] series on the PS2 could use microphones (Sometimes bundled with these game discs) with this method. 
:These adapters could either formally or informally be called: 
* SingStar USB Converter (Official)
* SingStar USB Converter Box (Official)
* SingStar USB Microphone Converter
* SingStar Microphone USB Adapter/Converter
* SingStar USB Converter Microphone Adapter
Steering wheels are also supported for many racing games via a USB adapter.

While PCSX2 isn't benefiting from a working USB plugin in its original release, Jackun, a PCSX2 plugin author, made a [https://github.com/jackun/USBqemu-wheel USB plugin] that supports a microphone in most games and even a steering wheel for racing games.
:A compatibility list of the working titles with this plugin can be found [https://forums.pcsx2.net/Thread-Qemu-USB-Wheel-Storage-mod-Singstar-test?pid=320737#pid320737 here].

==Arcade Hardware [https://www.system16.com/base.php#1 variations]==
Notice that [[Play!]] is still in relatively early stages so the gaming experience might not be perfect.

Also there are pull requests and feature requests for implementing some of these variations or its features to these emulators, so it is being worked on actively.<ref>[https://github.com/PCSX2/pcsx2/issues/3613 Feature request: support for Namco Arcade systems based on PS2 for PCSX2], [https://github.com/jpd002/Play-/pull/1301 2x6 touchscreen support for Play!]</ref>

:A [https://github.com/987123879113/pcsx2/wiki#builds fork of PCSX2 (987123879113)] supports the emulation of the Konami Python 2 ([https://github.com/987123879113/pcsx2/wiki/Setup#required-setup Guide]). This fork requires MagicGate key files into the bios folder (civ.bin, cks.bin, eks.bin, and kek.bin) and you must use <abbr title="SHA-1: 0ea98a25a32145dda514de2f0d4bfbbd806bd00c"> "ps2-0190j-20030822.bin" BIOS</abbr>.
::This fork does not and will never support Python 1 or system 246/256 games as those would require much more work than a simple USB device to make work. The MagicGate code being used in this fork also does not support [https://github.com/PCSX2/pcsx2/pull/4274 memory card MagicGate encryption stuff] properly (the memory card dongles used for Python 1 and System 246/256) so those platforms aren't really any closer to working compared to before.
:MAME romsets of Python 2 games won't work on this fork as they are missing ILINK_ID files.

''Not to be confused with the [[PlayStation emulators|original PlayStation]].''

The PSX is a Sony digital video recorder with a fully integrated PS2 console. It was also the first device to use Sony's XrossMediaBar (XMB) graphical user interface, which was later used on the PlayStation Portable, the PlayStation 3, some Blu-ray Disc players, and 2008-era BRAVIA TVs.

None of the PSX features have been emulated yet.

Twitter user @DiscoStarslayer claims to be [https://twitter.com/DiscoStarslayer/status/1570428063502012417 working on bypassing the HDD encryption of the PSX], which could result in this hardware being emulated, and it would allow for replacing the HDD in those consoles. This user also encourages dumping the content of the HDD of your PSX using a [https://twitter.com/DiscoStarslayer/status/1592187362947526657 guide] made by a PCSX2 contributor called [https://twitter.com/_987123879113 987123879113]

==Emulation issues==
Despite a large interest in PlayStation 2 emulation due to its sizable collection of games, it is still one of the harder consoles to emulate for several reasons.

First of all, many people believe that since the main CPU (Emotion Engine) runs at a clock speed of 294 Mhz (299 Mhz on later revisions), it would make emulation easy on recent hardware. But this isn't the case because the clock speed of the emulated CPU is not necessarily indicative of the ease of emulation (e.g. [[Sega_Saturn_emulators#Emulator_development|Sega Saturn emulation]]). Specifically, the PlayStation 2's CPU contains a multitude of custom sub-components and chips such as the FPU co-processor, 2 Vector Units, IOP, SPU2, Graphics Synthesizer, and SIF which together work asynchronously to comprise the 128-bit Emotion Engine. Emulating them perfectly with correct timing requires an enormous amount of power. Moreover, the PlayStation 2, just like PlayStation 1, uses the MIPS architecture instead of standard x86 code, thus making emulation slower.<ref>https://forums.pcsx2.net/Thread-Why-is-PCSX2-slow</ref>

Another big problem is the emulation of PlayStation 2’s floating-point unit (FPU) because it doesn’t follow the IEEE standard. To keep it simple, just changing a couple of numbers will cause glitches to occur to the game’s graphic (VU) and logic (EE), resulting in things like broken AI, odd behaviors, and/or graphical bugs. While PCSX2 allows for either clamping/rounding on both VU and EE as a solution to fix these glitches, it remains by far not the most accurate way to emulate the PlayStation 2's FPU.<ref>https://wiki.pcsx2.net/PCSX2_Documentation/Nightmare_on_Floating-Point_Street</ref><ref>https://github.com/PSI-Rockin/DobieStation/issues/51</ref>

To conclude the problems with PlayStation 2 emulation, we come to hardware rendering. The PlayStation 2’s graphics pipeline acts very differently from modern GPU cards, and emulating it in HW mode with any degree of accuracy is difficult. This is due in part to the versatility of the PlayStation 2, the fact that it doesn’t use fixed shaders, or that even the games themselves do not use a consistent formula to achieve different graphical effects. Various emulation enhancements like display resolution scaling lead to the typical “black lines glitch” because of the use of a non-integer resolution. While the [https://github.com/PCSX2/pcsx2/tree/master/pcsx2/GS/Renderers hardware renderer backends on PCSX2] greatly improved on many of these issues, [https://wiki.pcsx2.net/Category:Software_rendering_only_games there are considerable amount of games still require “software rendering”] to fix many common glitches, which is [[PCSX2#System_requirements|significantly increases CPU ST performance requirement]] for the emulation and eliminating visual enhancement options.

In summary, The PlayStation 2 is a very complex machine that even game developers struggled to work with. It is difficult to achieve close-to-perfection PlayStation 2 emulation with actual PC hardware but thanks to [https://github.com/PCSX2/pcsx2/graphs/contributors PCSX2 team] it's now possible.

===MagicGate===
:[[Wikipedia:MagicGate]]
MagicGate, an encryption technology embedded within specific PlayStation 2 memory cards, relies on the [https://www.psdevwiki.com/ps2/MechaCon MechaCon] chip for security functionalities. MechaCon chip handles various tasks, including PlayStation 2 system security, game disc security, MagicGate, and KELF file decryption. Emulating MagicGate presents unique challenges because replicating its encryption process and hardware verification can be difficult and rightfully raising concerns about copyright situation [https://github.com/PCSX2/pcsx2/pull/4274#issuecomment-795316629][https://github.com/PCSX2/pcsx2/pull/10836#issuecomment-1954866179]. However there is a PCSX2 fork for this you can use, although you need MagicGate keys.
