Quake Wrapper - it's technically a mod for Xash3D Engine, which uses Xash3D Engine as a shell to launch original Quake game and even its' mods. Gameplay remains unchanged, but game interface and controls are more user friendly (mouse is fully supported, graphics is 32-bit, modern screen resolutions are supported etc.).
The original Quake soundtrack packaged for use in source ports/engines such as DarkPlaces or Fitzquake.
