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 at 300 MHz with 32MB of RDRAM system memory and 4MB 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 160 million units sold.

===Comparisons===
+
Unlike bsnes, byuu would also put accuracy at the forefront, at least at first, to uphold Near's vision for emulator design. This means that byuu would have higher system requirements and less enhancements than bsnes, but it will still aimed to offer more features than higan.
;[[PCSX2]]:The first and only PS2 emulator currently worth using. That said, it is underwhelming in the accuracy department, with thousands of bugs and graphical glitches. However, since version 1.6, the accuracy has greatly improved. The emulator is capable of playing 2535 games without any major glitches (regardless of speed) and playing 48 games at a non-playable speed or with major graphical or accuracy glitches.  Check the [[Game problems FAQ#PS2|Game Problems FAQ]] for the most difficult titles.
 
;[https://github.com/PSI-Rockin/DobieStation/ DobieStation]: Hundreds of titles go ingame, more accurate than Play! and even PCSX2 in some cases, but way slower than both at the moment. Designed to be fast, accurate and easy to use. An [[Android emulators|Android]] port is planned. Making rapid progress
 
;[[DamonPS2]]:Closed source emulator only for Android. Extremely shady, probably uses stolen PCSX2 code and might steal your data. Although it is much faster than [[Play!]], compatibility still lags behind [[PCSX2]].
 
;[[Play!]]:Can run quite a few commercial games but is still pretty far behind [[PCSX2]].
 
;[[sourceforge:projects/hpsx64/|hpsx64]]: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.

Essentially, think of it as the bridge between two extremes. The goal was to build on the success of bsnes, and to offer an easy-to-use interface for all of Near's emulator cores, rather than just for the SNES alone.
  
Despite a large interest in PS2 emulation due to its sizable collection of games, it is still one of the hardest consoles to emulate for a number of reasons.
+
After Near retired in July 2020, byuu was merged back into higan.
  
First of all: many people believe that since the main CPU (Emotion Engine) runs at a clock speed of 294Mhz (299Mhz on later revisions), it would make emulation easy on recent hardware. But this is not the case, because the clock speed of the emulated CPU is not necessarily indicative of the ease of emulation. Specifically, the PS2 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. In order to emulate them perfectly with correct timing requires an enormous amount of power. Moreover, the PS2 just like PS1 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 PS2’s own 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 or graphical bugs. While PCSX2 allows for the option of 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 PS2 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 on the problems with PS2 emulation, we come to hardware rendering. The PS2’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 PS2, 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 type of emulation enhancements like display resolution scaling leads to the typical “black lines glitch” because of the use of a non-integer resolution. While the OpenGL backend on PCSX2 greatly improved on many of these issues, most games still require “software rendering” to fix many common glitches, which in turn slows down the emulation. Although Games using mip-mapping (Ratchet & Clank, Ace Combat, etc...) and games running on the Snowblind Engine are playable in OGL HW mode with minimal problems on high-end PCs.

In summary, it is not possible to achieve close-to-perfection PS2 emulation with actual PC hardware, and even if it was possible, the results would most likely be unplayable.  The PS2 is simply a very complex machine that even game developers struggled to work with.

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 can be used on PC with [https://web.archive.org/web/20070327192750/http://eyetoy8057.sourceforge.net/cms/ unofficial drivers].

==USB Plugin==
 
 
 
Some PS2 games make use of an 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 were able to 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 a large number of racing games via an 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 steering wheel for racing games. The plugin is still updated nowadays.
 
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].
