* [[Mednafen|Mednafen PSX]] 's PlayStation emulation is an emulator focused on [[accuracy]]. It is extremely , which makes it very compatible, outdoing even and it's been known to outperform Sony's official PSone emulator in accuracy tests. <!-- Do note if you find an exception, though. It --> However, there are a few small hurdles to using it; it requires a very specific BIOS for each region. The minimum system requirement is a Core 2 Duo at 2 GHz clock. <br, and the program itself interfaces from the terminal/>Mednafen itself is command -line only and ; it has no GUI. You can still drag-and-drop the cue files on the executable to load games, and the program logs errors to a text file called <code>stdout.txt will log errors if </code> whenever a crash happens. There are external GUI launchers availablelike mednaffe. <br/>Both [[RetroArch]] and [[BizHawk]] have cores based on this emulator. They, and they're easier to use than the standalone emulator thanks to their GUIsbecause they have frontends. The RetroArch fork of Mednafen PSX (known as Beetle PSX, or mednafen-psx, or mednafen-hw-psx) has several experimental modifications and enhancements not 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 (though ; an alternate alternative core with exists for hardware rendering exists). PGXP was also ported to the RA cores. * [[PCSX-R]] is an open source [[Recommended_PSX_Plugins|plugin]]-based emulator. The main reason to use this over mednafen is that it can render at higher resolutions without being unplayably slow.** '''PGXP''' is a fork of PCSX-R that aims to remove some of the limitations of the PS1 by adding texture correction, reducing polygon wobble, and reducing polygon culling. It also adds CPU overclocking, and makes a hack in PCSX-R toggleable.

* [[ePSXePCSX-R]] is a fairly standard an open-source [[Recommended_PSX_Plugins|plugin]]-based emulator like . The main reason to use this over mednafen is because its internal resolution can be raised with little to no performance hits.** '''PGXP''' is a fork of PCSX-Rthat adds texture correction, polygon wobble reduction, and polygon culling reduction. Accuracy is typically about the same between the twoIt also adds CPU overclocking, however due to being closed source and constantly lagging behind allows a hack that was originally disabled in PCSX-R in features, .** PCSX-ReARMed is an ARM port of PCSX-R is generally recommended over it. Since version 1.8.0, ePSXe has been available on Android as sharing a paid appsimilar core, but it optimized for portable handheld devices. The biggest draw is its NEON software renderer, which is not recommendedboth fast and accurate, and has the ability to render at higher resolutions without resorting to HLE plugins.

* PCSX[[ePSXe]] is a fairly standard [[Recommended_PSX_Plugins|plugin]]-ReARMed is essentially the ARM version of based emulator like PCSX-R, sharing a similar core, but optimized for portable handheld devicesand as such the accuracy is typically about the same between the two. Its biggest draw is its NEON software rendererclosed-source nature has had it constantly lagging behind in features, which is both fast and accuratewhy it's not recommended. Since version 1.8.0, and ePSXe has the ability to render at a higher resolution without resorting to HLE pluginsalso been commercially available on Android, but it's also not recommended.

* [[XEBRA]] is a <abbr title="Because of this, there are no known UI mods at this time.">Japanese</abbr> emulator, but it has very high compatibility. Games that require subchannel data are not supported, but most other games run flawlessly. Obtuse user interface as the developer is Japanese, so be prepared.

* [[No$|NO$PSX]] is a well-rounded emulator by the same author of [[No$|NO$GBA]]. There are has two versions of the emulator; , but standard users will want to use the cut-down gaming version. It Made in the same style as [[No$|NO$GBA]], where it handles the PocketStation, it offers decent compatibility with very low spec requirements – the programmer's philosophy is to deliver a working application out of the box. As of today, it's It is still being actively developed. PocketStation is emulated through [[No$|NO$GBA]].

* [[PSX|PSXfin]] is a simple simpler emulator with simple usage. It has a lot of compatibility issues,<ref name="psXcompat">http://psx.silvanthalas.com/psx.html</ref>. It requires a BIOS for use, but compatibility with each one is inconsistentespecially when using different BIOSes. Development has been halted and it remains closed -source. It's really only useful for very old toasters.

* [[PCSX2]] is primarily a PlayStation 2 emulator. Recently, but emulation of a hardware feature has been merged into the main project that allows the same backwards compatibility with PS1 games has been implemented, and PS1 games can now be played in PCSX2 the way they would be in a PS2 console, and the internal resolution can be increased as well. However, one thing to note is that backwards compatibility in the original PS2 hardware didn't cover all games in the PS1 library, and these limitations still extend to PCSX2's emulation.

For even further an in-depth analysis of each emulator on a technical level, check out [[PS1 Tests]].

It's generally recommended to use Mednafen or PCSX-R(or one of its forks). Many use Mednafen for its accuracy at native resolution, and PCSX-R for 3D games (that don't use prerendered backgrounds) because of support for plugins which allow for better graphics quality than original hardware. Unfortunately , the best plugins for increasing internal resolution and shader support (Pete 's OpenGL2 v2.9 and Edgbla gpuBladesoft v1.42a) are closed -source and haven't been updated for years.

* POPS (short for PlayStation On PSP System) is the name of the program for the PSP made by Sony 's official PSone Classics emulator for their PSone Classics PlayStation Store releases. It utilizes [[PSP Eboots|EBOOTs]], a form of binary file for PSP, instead of bin/cue/etcdisc dumps, which can be made using a converter if desired. Compatibility is very high due to it being made by Sony and similar hardware design; although the GPU is emulated, the PSP containing a CPU that is very similar close to the one found in the PlayStation. This makes it so it isn't purely an emulator, although it does emulate the PS1s GPUPSX and would naturally speed up performance on its own. It includes support for multi-disc games (within the one EBOOT). Only the native PS1 resolution is supported, with games being stretched as the user wishes to fit the screen. POPS is also available on the PlayStation 2, although compatibility is not as high.

* PS2PSXe is another an unofficial PS1 emulator for the PS2. However, this one is unofficial. Compatibility compatibility is very low. It is generally recommended to Double disc swap for the PS2, which in turn will utilize the built-in PS1 hardware available in every PS2. Double swapping (using the same method as a real PS1) is required for PS2s with model numbers SCPH-100xx - SCPH-390xx.

* The PlayStation 3 has a built-in software emulator with very high compatibility, as it which is used for PSone Classics releases on the system PlayStation Store as well as actual PS1 for handling PlayStation discs.

* WiiSX is a port of PCSX to the Wii. Compatibility is fairly low due to the weak power of the Wiiand differing hardware designs that make PowerPC requirements a little stronger. This plus the lack of updates to the emulator makes it It's generally not worth usingsince it doesn't get updated.
