What is ePSXe?
ePSXe is a Sony Playstation emulator for your PC running under Windows, programmed by calb, Galtor and _Demo_ !
ePSXe takes advantage of the popular PSX plugins system, which has been introduced to the scene by PSEmu Pro, a great project which got stopped after a beta got leaked to the public. ePSXe and it's components are all completly programmed in C++. Right now, it doesn't look as if the source might ever get released, but you'll never know.
ePSXe is also being programmed on two OSes at the moment, MS Windows 9x/Me/2k/XP and linux. Although this limits some parts of the program (for example making a proper windows GUI ;)), it's an extreme advantage only having to code changes into one source and getting the results for both platforms.
