EPSXe (advanced PSX emulator) is a PlayStation video game console emulator for x86-based PC hardware with Microsoft Windows or Linux, as well as Android devices. It was written by three authors, using the alias calb, _Demo_ and Galtor. ePSXe is closed source except the application programming interface (API) for its plug-ins.

Programs that allow users to play games from optical drives or from images stored on the system storage. Most playstation games work perfectly with this app, and others have a few issues that can be fixed by installing a game-specific patch.

ePSXe can run most PlayStation games correctly. Very few games run perfectly without configuration and extensive testing by error checking. In the event that the game does not run successfully, patches written for the game in question may be used, although there are very few games with patches.

Features of EPSXe

- ePSXe does not come with any PlayStation BIOS image, requires users to provide one for the emulator. Version 1.9.25 has added BIOS HLE support, allowing it to mimic the effects of the PlayStation's BIOS, though compatibility is currently lower than the official BIOS.

- ePSXe uses plug-ins to simulate the functions of the GPU, SPU (audio) and CD-ROM, a model first established in PSEmu Pro. Games can be downloaded from a computer's CD drive or from one of a variety of CD images directly from the user's hard drive.

- A patch feature that allows users to apply game patches. Games do not necessarily need to run properly or even start, which can be edited and played through the use of the ePSXe patch file in .ppf format. Not all error-prone games have a ppf patch written for them.

How to play EPSXe game

It includes virtual touch screen pad support, hardware button mapping (Xperia Play, phones with keyboards or gamepads, external bluetooth or USB gamepads like WiiMote, Sixaxis, Xbox 360, Moga, Ipega) and analog sticks. ePSXe supports OpenGL HD advanced graphics thanks to the Peopsxgl Plugin, cheat codes as well as compatibility and memorization with the PC version.


- CD-ROM: ePSXe comes with the core CD-ROM plug-in, but many other software are available for free software download and many can emulate up to seven different reading modes.

- SPU: The SPU plug-in can simulate everything from music to sound effects, with varying degrees of success depending on the plug-in settings and of course the plug-in used.

- Input: The core plug-in is sufficient, but there are others that allow more functionality.

- GPU: Most GPU plug-ins run with Direct3D, OpenGL or Glide API and are available as free or open source software. Many GPU plugins require game-specific hacks to run the game.
