:Quickly became a top contender on the basis that it has high compatibility and a built-in GUI. Its stated goal is to be "as accurate as possible while maintaining performance suitable for low-end devices." While PCSX-R has long dethroned ePSXe in features, DuckStation is the first to address all the shortcomings of plugin-based offerings thus far, as all of its features are available out-of-the-box, and no configuration is necessary to get games running outside of obtaining the original system firmware. Duckstation has modern [[#Enhancements|enhancements ]] built-in like PGXP, upscaling, texture filtering, emulated CPU overclocking, hardware (D3D11, D3D12, OpenGL, Vulkan) and software rendering (both of which have true color (24-bit) support). It also natively supports MAME's Compressed Hunks some of Data (CHD) format (you don't have to extract it)the [[#Hardware_features_and_peripherals|hardware features, which shrinks the size of CDs losslessly while also storing all of its data under a single fileperipherals]]. An Android version is also available, although it doesn't have feature parity with the desktop builds. The unofficial libretro core (swanstation) and standalone version are Retroachievements-compatible.

:Is heavily focused on [[Emulation accuracy|accuracy]], which makes and just like DuckStation, it has very compatiblegood compatibility. It's even been known to outperform Sony's official PS1 PlayStation emulator in some of the accuracy tests.<!-- Do note if you find an exception, though. --> However, there are a few hurdles to using it; it requires a specific BIOS for each region, and the program interfaces from a shell only; it has no GUI. You can still drag-and-drop CUE files into the executable to load games, and the program will log errors to a text file called <code>stdout</code> whenever a crash happens. External GUI launchers are available.

::This fork by the RetroArch developers has several experimental modifications and [[#Enhancements|enhancements ]] that aren't present in the standalone version, including a widescreen hack, CPU overclocking for smoother framerates, and increasing the internal resolution up to 8x. Increasing the resolution carries a ''heavy'' performance cost, however, since graphics are rendered in-software, an alternative core exists for hardware rendering. See [https://www.maketecheasier.com/retroarch-ps1-emulation/ this 2018 guide] for setting up Beetle HW in RetroArch. Needs high-end specifications to run at full speed for Android and iOS devices.

:An emulator made in Japan that also has high compatibilitythough games that require subchannel data are not supported. It is heavily focused on [[Emulation accuracy|accuracy]] similar to Mednafen. The UI is in English, but because it's not the developer's native language, some of the naming conventions may seem weird compared to other emulators (for example, the BIOS is referred to as OSROM). Luckily, there's a [https://www.reddit.com/r/emulation/comments/9a4mwk/xebra_guide_ps1_emulator/ guide] that helps explain how each option works. Games that require subchannel data are Also supports some of the [[#Hardware_features_and_peripherals|hardware features and peripherals]] which is not supported, but most found in other games run flawlesslyrecommended emulators.

:Uses two cores ported from [[Mednafen]] for PlayStation emulation. : "Octoshock" core (by zeromus) and "[https://github.com/TASEmulators/BizHawk/pull/3093 Nymashock]" core (by CasualPokePlayer). [https://www.speedrun.com/twl/thread/nl2de BizHawk emulator is accepted for specific games by Speedrun community], BizHawk is and actually more preferred compared to other recommended emulators because at least for speedrunning : it's more suitable for catching those who try and pass off RTA runs as TASes. The "Nymashock " core is more preferred between the two, with public talks about removing the "Octoshock " core. Further that [https://www.speedrun.com/ctr/forums/sqeu6 only Mednafen and BizHawk accepted for certain games like CTR].
