ePSXe (enhanced PSX emulator) is an emulator of the Sony PlayStation video game console for x86-based PC hardware. It was written by three authors, using the aliases "Calb", "_Demo_", and "Galtor". It has been described as the best freeware Playstation emulator available. ePSXe makes use of a plugin system to emulate GPU, SPU, and CD drive functions * GPU: Most GPU plugins run with either Direct3D, OpenGL, or the Glide API, and are available freeware or open source. * SPU: The SPU plugins can emulate everything from music to sound effects, with varying degrees of success depending on the plugin settings, and of course the plugin being used. * CD-ROM: ePSXe comes with a core CD-ROM plugin, but many others are available for freeware download and many can emulate up to seven different types of read modes. * Input: The core plugin is sufficient, but there are others that allow for more functionality. It is even possible to plug in and use a DualShock controller with a USB adapter. If you want to add plugins to the epsxe, go to $HOME/.epsxe, where you will find the plugins directory. Note that this script installs many needed directories owned by root:games and writable by that group; if you want a user to be able to install plugins, then make sure they are in the games group.
