The number of units sold worldwide was about the same as the Xbox 360. The PlayStation 3 initially included a feature called [[#OtherOS|OtherOS]],<ref group=N2>Which allowed the console to run many distributions of Linux and BSD in a separate partition as long as they supported PowerPC.</ref> but once it was removed shortly after the PS3 Slim model was released citing "security concerns", fail0verflow had a jailbreak detailed in 2010, giving way for [[PS3 Modding|modders to downgrade firmware on a specific version]] and install a custom firmware, something Sony would patch in newer updates until an exploit was released for 4.82. Emulation only started gaining traction in the late 2010s, as [[RPCS3]] had made strides in improving its largely HLE-based emulation. It has since become the emulator of choice.

;[[RPCS3]]:An RPCS3 is an open-source [[High/Low_level_emulation|hybrid approach]] emulator for 64-bit Windows, GNU/Linux, BSD and macOSand it stands as a remarkable feat in PlayStation 3 emulation, successfully tackling the intricate [[#Emulation_issues|PlayStation 3's complex architecture]] through innovative techniques. While it isn't anywhere near as compatible as [[Dolphin]] is for [[GameCube emulators|GameCube]] or Wii, it has still made immense progress compared to its early days, when development was slow and seemed like it wasn't really going anywhere.

PlayStation consoles have always been notorious for system complexity (e.g. [[PlayStation_emulators#Emulation_issues|PlayStation]], [[PlayStation_2_emulators#Emulation_issues|PlayStation 2]]). Sony's gamble of their technology being emulator-unfriendly makes them developer-unfriendly as well, and the system's weaker performance in cross-platform games proves it. Even if done properly, [[High/Low_level_emulation|an LLE approach ]] would be performance suicide, as some things just have to be abstracted enough to get high framerates in games. The situation is so bad that Sony seems to be incredibly hesitant to produce an [[Official_emulators|official PS3 emulator ]] for the newer PlayStations. Simply because they wouldn't be able to justify the extremely high potential development cost to investors.<ref>[https://youtu.be/6WkpaJkB2M8 Why PS4 Doesn't Have Backwards Compatibility and Xbox One Does] (Mystic.

The RPCS3 developers using ahead-of-time recompilation using LLVM.RPCS3 is not just compiling the code it runs, it's also needs to compile a realtime environment simulator e.g. the 128x128bit register file, LS sram, the very weird memory flow controller, etc [https://discord.com/channels/272035812277878785/272083901277667342/1200171144603512892]. SPEs closer to [[PlayStation_2_emulators#Emulation_issues|VUs from PS2]] than to a GPU. They're a SIMD cluster, don't be fooled by their apparent similarity to GPUs. GPU are low throughput but very wide. SPEs are also wide, but not so much so. However, their individual thread throughput is insane even compared to a something like RTX 4090 GPU. It's not possible to beat SPUs 1:1 (it's ALL vector, it doesn't have scalar registers at least not general-purpose ones), they have 128 registers and very low latency SRAM, almost no memory fetches and everything is async. Although AVX-512 comes close in performance (at 5+ GHz). GPUs on the other hand are around 10-100x slower, but that's just because of how their cores are designed and the fact that SPU kernels are optimized to run in much smaller groups. There's too much working against emulation at 3.2 GHz rate since most SPU instructions need many instructions on PC (like dozens in some cases), so the PC side needs to be an order of magnitude faster.[https://discord.com/channels/272035812277878785/272083901277667342/1197648306084524202]* '''[[wikipedia:RSX_Reality_Synthesizer|RSX (Reality Synthesizer)]]''': The [[PlayStation 4 emulatorsPlayStation_4_emulators#Emulation_issues|PlayStation 4GPU]] also went unemulated for a long time, simply because of how many components were just undocumented.
