ePSXe is considered the #1 PSX emulator. Most games emulate flawlessly, but you may encounter lock-ups and an assortment of bugs. ePSXe lets you play any of your Playstation games on your computer via your CD-ROM or with Playstation ISO's (FYI, an ISO is a file or archive of files which build up a single CD video game).

NOTE: To use any ISO or game (that will NOT be available, ever, on HeelpBook) with ePSXe you will need a BIOS.

Having a good video card is important if you want the best ePSXe experience. With Pete's OpenGL plug-in (and others), ePSXe can render 3D graphics to fit a specified resolution. That means 3D edges will be sharp instead of pixilated.
