you need to extract it. Then if you want to play it on a chipped PSX, you need to burn it (as an image, not a data cd) at low speed (1x or 2x, no more than 4x), onto branded media such as TDK or Verbatim. To play it on an emulator, you either mount the image onto a virtual drive, or open it directly with the emulator.
