PlayStation 2 emulators
|Type||Home video game console|
The PlayStation 2 (PS2) is a sixth-generation console released by Sony on October 26, 2000 and it was retailed for $299.99. 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.

- PCSX2 (compatibility)
- The first Playstation 2 emulator. Accuracy has continuously improved during dev builds. The emulator is capable of playing most titles without any major glitches. Check the Game Problems FAQ or the Official Compatibility List for information regarding playability.
- A closed-source freeware emulator, partially forked from PCSX2. It's designed to be more optimal for ARM-based platforms, primarily those running Android.
- Able to run a decent amount of commercial games. Development is almost all done by the single maintainer jpd002. Compatibility information is located on the emulators home page. Also has a playable Android port.
- Many titles can go ingame, focused on accuracy, and therefore inherently slower than Play! or PCSX2. A compatibility list is provided here. Once accuracy has reached an acceptable point, the focus will be shifted to optimization/speed.
- HPS2x64 (compatibility)
- 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 emulation. There is also a mirror that has fixes done to it.
- Closed-source payware/malware emulator only for Android, illegally based off of PCSX2, Play! and PPSSPP. It can hardly run any games and behaves very much like virus software. It is best to NOT use this emulator.
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 several reasons.
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. 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.
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.
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 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 unofficial drivers. It also works natively with the PS3.
PCSX2 is the only emulator that can emulate EyeToy mechanics in games.
Some PS2 games make use of a USB adapter with a module/dongle consisting of two jack ports for microphones. Installments from the 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 a USB adapter.
While PCSX2 isn't benefiting from a working USB plugin in its original release, Jackun, a PCSX2 plugin author, made a 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 here.
Konami Python 2
Konami Python 2 is a Konami arcade system based on PlayStation 2 hardware.
A fork of PCSX2 supports emulation of Konami Python 2. Notice this fork requires extra BIOS files (civ.bin, cks.bin, eks.bin, and kek.bin).
Not to be confused with original PlayStation.
The PSX is a Sony digital video recorder with a fully integrated PlayStation 2 home video game console, which is also the first device to use Sony's XrossMediaBar (XMB) graphical user interface, which was later used on the PlayStation Portable, PlayStation 3, some Blu-ray Disc players, and 2008-era BRAVIA TVs.
None of the PSX features have been emulated yet.
