'''ePSXe''' (''enhanced PSX emulator'') is a [[PlayStation (console)|PlayStation]] [[video game console emulator]] for [[x86]]-based [[Personal computer|PC hardware]] with [[Microsoft Windows]] and [[Linux]], as well as devices running [[Android (operating system)|Android]]. It was written by three authors, using the aliases ''calb'', ''_Demo_'' and ''Galtor''. ePSXe is [[Proprietary software|closed source]] with the exception of the [[application programming interface]] (API) for its plug-ins.

== Development ==
For half a year, ePSXe was developed in private, with part of this initial development being carried out by _Demo_, previously known for his work on the [[Super Nintendo]] emulator [[ZSNES]].<ref>https://www.epsxe.com/files/ePSXe_FAQ.txt {{Bare URL inline|date=August 2024}}</ref> When released on October 14, 2000, ePSXe was a revolution in the PlayStation emulation scene, boasting higher compatibility and performance than other emulators of the system at the time.<ref name="retrogames"/>

After ePSXe 1.6.0 was released on August 5, 2003,<ref name="epsxe1.6" /> its development seemed to halt, with speculation that the source code had been lost due to a [[hard disk failure]]. However, on April 5, 2008, the developers of ePSXe made a public statement revealing that in the summer of 2007, they had decided to continue development of the emulator, due to encouragement from users. On May 24, 2008, ePSXe version 1.7.0 was released.<ref name="epsxe1.7" />

After another hiatus, the developers came back on August 30, 2012, announcing the release of ePSXe for Android,<ref name="android" /> as well as stating that ePSXe for Windows was in testing of version 1.8.0. This version was released on November 9, 2012.,<ref name="epsxe1.8" /> being followed by 1.9.0 in 2013<ref name="ePSXe 1.90" /> and ePSXe 1.9.25 in 2015.<ref name="ePSXe 1.9.25" />

== Features ==
ePSXe was one of the early emulators to make use of plug-ins to emulate [[Graphics processing unit|GPU]], SPU (sound), and [[CD-ROM]] drive functions, a model first established in PSEmu Pro. Games can be loaded from the computer's CD drive or from one of many types of [[Disk image|CD images]] directly from the user's [[hard drive]].

A patching feature allows the user to apply game patches. Games that do not necessarily run properly, or even start at all, can be fixed and played via the use of ePSXe patch files in .ppf format. Not all games prone to bugs have ppf patches written for them.

Until version 1.9.25, ePSXe could only function with an image of an official Sony PlayStation [[BIOS]]. Since the various PlayStation BIOS images are [[copyright]]ed by Sony, it is illegal to distribute them. For this reason, ePSXe does not come bundled with any of the PlayStation BIOS images, requiring the user to provide one for the emulator.<ref>{{cite web|url=http://www.epsxe.com/forum.php |title=ePSXe message board rules |publisher=ePSXe.com |access-date=2013-08-04}}</ref> Version 1.9.25 added [[high-level emulation|HLE]] BIOS support, allowing it to mimic the effect of the PlayStation's BIOS, although compatibility is currently lower than an official BIOS.<ref name ="ePSXe 1.9.25" />

=== Plug-ins ===
* GPU: Most GPU plug-ins run with either [[Direct3D]], [[OpenGL]], or the [[Glide API]], and are available as [[freeware]] or [[open-source software|open-source]].<ref>{{cite web|url=http://www.racketboy.com/retro/sony/ps1/enhance-ps1-graphics-with-the-best-epsxe-plugin-settings |title=Enhance PS1 Graphics With The Best ePSXe Plugin Settings |date=6 August 2007 |publisher=Racketboy.com |access-date=2013-08-04}}</ref> Many GPU plugins require game-specific hacks to run games.
* SPU: The SPU plug-ins can emulate everything from music to sound effects, with varying degrees of success depending on the plug-in settings, and of course the plug-in being used
* CD-ROM: ePSXe comes with a core CD-ROM plug-in, but many others are available for freeware download and many can emulate up to seven different types of read modes
* Input: The core plug-in is sufficient, but there are others that allow for more functionality.

=== Compatibility ===
ePSXe is able to run most PlayStation games somewhat accurately. Few games run flawlessly without extensive configuration and trial by error testing. In the case that a game does not run successfully, [[patch (software)|patches]] written for the game in question can be used, though few games have patches available.<ref>{{Cite web|url=http://ngemu.com/forumdisplay.php?f=46|title=Game compatibility list for ePSXe}}</ref>
