Emperor: Battle for Dune is an RTS game made by Westwood Studios and Intelligent Games. It is the last game by Westwood Studios set in the Dune universe. Unlike Dune 2000 which was a remake of Dune II, Emperor: Battle for Dune was a proper sequel that took place after the storyline of the original, featuring entirely different factions as opposed to ones sharing most of their arsenals. It was the first Westwood-branded RTS to use a 3D engine, but it used Intelligent Games' Xanadu engine rather than Westwood's then-in development W3D, contrary to subsequent beliefs. It was distributed on 4 CD-ROMs, one for installation and the other three for each faction's campaign.

Due to security updates to Windows 10 and later and certain prior versions of Windows, the game will not run without using the official install fix due to an un-fixed version using SafeDisc. This fix was originally intended for computer configurations at the time of release which were incompatible with SafeDisc despite the then-available versions of Windows still supporting it.

Essential improvements

Bypassing SafeDisc

The game will not run on Windows 10 and later and certain prior versions of Windows without using an official installation fix (see the SafeDisc DRM article for more information).
Follow the procedure[1]
  1. Copy the contents of disc 1 to the hard drive.
  2. Replace the setup executable with the one from the official install fix.
  3. Install the game using the new setup executable.
  4. Install Patch 1.09.
  5. Extract the file EMPEROR.EXE from the install fix archive and copy it to <path-to-game>, overwriting the old file.


This fix also applies to certain computer configurations which existed during the game's original release, which were incompatible with SafeDisc.


Patch 1.09 updates the game to the latest version.

Lag fix in Windows 8 and newer

Use dgVoodoo2[3]

The game lags terribly in modern operating systems. In order to fix this, use dgVoodoo 2.

  1. Download dgVoodoo 2 and unpack it in <path-to-game>.
  2. From the MS\x86 subfolder, copy all files to the main directory.
  3. Run dgVoodoo2 setup through dgVoodooCpl.exe in the game directory.
  4. Select your appropriate graphics card from the drop down menu in "Adapters to use/enable"; in "Appearance," choose "Centered". Now click on the "DirectX" tab above. Input "512 MB" in the "VRAM" menu. Deselect "dgVoodoo watermark". Click on the "apply" button, then press "OK."
  5. Run the game. Notice the main menu will still lag, but the game itself will run fine.
