The ePSXe was written by three authors, going by the names “Calb”, “_Demo_”, and “Galtor”. Before its release, it was developed in secret and was released on October 14, 2000, revolutionising the Playstation emulator scene with its high compatibility rate and speed compared to other emulators.
After the 1.6.0 release, rumours were going around that the source code had been lost due to a hard drive failure, however, on April 5, 2008 the authors stated that they had decided to carry on development of the ePSXe in the summer of 2007, and version 1.7.0 was realsed on May 24, 2008.
Like many other high end emulators, like the PCSX2 and PJ64 for example, the ePSXe uses a plugin system which allows you to choose different plugins from different authors, further imporving the game compatibility rate and versatility of the emulator. Most games play fine, although any that have graphical glitches can usually be fixed by using alternate plugins, which can be downloaded from here. I believe that the emulator plugins are compatible with other emulators such as the PCSX and pSX.
I think this is a great emulator, all the games (ones that I’ve played that is) run nearly perfectly and the sound is very high quality. The only drawback for me is that it isn’t open source, but that is no problem for most users of the emulators, besides, PCSX is open source, can’t complain.
Anyway, if you’re ever feeling nostaligic and you want to flah back to the times when you first got that PS1, this is definitely and emulator you should check out.
ePSXe is a plugin-based PlayStation emulator, though it comes with internal plugins for everything in additional to being able to us the same plugins as other emulators. It supports multiple CD-ROM formats (.bin/.cue, multi-bin/cue, .mdf/.mds, .ccd/.bin/.sub, .pbp, etc), including sub-channel support and PPF patching on the fly. Multi-tap up to 8 players are supported.
There are versions for Windows, Linux and Android. Linux builds are 32bit x86 only and are difficult to get running on most modern systems.
A real PlayStation BIOS is recommended but not required. ePSXe can run games without an official PS1 BIOS via HLE, but compatibility will be lower and memory card support limited.
VERY IMPORTANT: Save states done with a official PS1 bios are NOT compatible with save states done with ePSXe HLE bios (Besides it uses a different namespace).
