PS1 Emulator


ePSXe (enhanced PSX emulator) is a PlayStation video game console emulator for x86-based PC hardware with Microsoft Windows or Linux, as well as devices running Android. It was written by three authors, using the aliases calb_Demo_ and Galtor. ePSXe is closed source with the exception of the application programming interface (API) for its plug-ins.

For half a year, ePSXe was developed in private. When released on October 14, 2000, ePSXe was a revolution in the PSX emulation scene, boasting higher compatibility and performance than other PlayStation emulators of the time.

After ePSXe 1.6.0 was released on August 5, 2003, its development seemed to halt, with rumors claiming 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.

After another hiatus, the developers came back on August 30, 2012, announcing the release of ePSXe for Android, as well as saying that ePSXe for Windows was in testing of version 1.8.0. This version was released on November 9, 2012.

As with many modern emulators, ePSXe makes use of plug-ins to emulate 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 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 copyrighted 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. Version 1.9.25 added HLE BIOS support, allowing it to mimic the effect of the PlayStation’s BIOS, although compatibility is currently lower than an official BIOS
