NTVDMx64 was initially incompatible ==Emulation issues==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.<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 Windows 11 x64PS2 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 NTVDMx64 was initially unable 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 run when Secure Boot 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 enablednot possible to achieve close-to-perfection PS2 emulation with actual PC hardware, and even if it was possible, which the results would most likely be unplayable. The PS2 is simply a very complex machine that even game developers struggled to work with. ==EyeToy==The [[wikipedia:EyeToy|EyeToy]] is required for Windows 11 x64 a device similar to install a camera or a webcam. It's an accessory developed by Sony and runmanufactured 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]. It also works natively with the [[PlayStation_3_emulators|PS3]]. PCSX2 is the only emulator that can emulate EyeToy mechanics in games. ==USB Plugin==Some PS2 games make use of 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 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 AdapterSteering 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, Leecher1337 added loader support made a [https://github.com/jackun/USBqemu-wheel USB plugin] that supports a microphone in most games and even steering wheel for Windows 11 x64 racing games.
