EPSXe

Enhanced PSX Emulator most known as ePSXe is an emulator of the PlayStation video game console. Its initial release was on October 14, 2000. ePSXe is freeware currently available for download.

As with most modern emulators, ePSXe requires the use of plugins to emulate GPU, SPU, and CD drive functions, a requirement first established with PSEmu/PSEmuPro. ePSXe also requires the use of a BIOS file dumped from a PlayStation. This is to avoid a legal problem, as it is copyright infringement to provide the Sony's BIOS for download, and unlike some other emulators, ePSXe cannot high-level emulate the BIOS. Technically, the only legal way to use ePSXe is to dump the BIOS from a PlayStation you own. ePSXe can run from CD and many types of CD images directly from the user's hard drive. With a few exceptions, it is capable of nearly flawlessly emulating many PlayStation games. Of course, this is dependent on the plugins used and how they are configured.
