Essential improvements[edit]


The latest official patch v1.05 is available here, at www.sierrahelp.com and at soggi.org.
A full list of all available patches can be found at www.sierrahelp.com.

Command-line parameters[edit]

The following command-line parameters may improve quality on newer systems, or enable extra functionality:

Argument Description
/triple Enables OpenGL triple buffering, improves graphical quality and removes flickering at higher resolutions. Use unless it causes problems.
/enable3DNow Enables the 3DNow processor instruction set if available. Use unless it causes problems.
/enableSSE Enables the SSE processor instruction set if available. Use unless it causes problems.
/disableAVI Disables the intro movies when the game starts.
/nofastfe Disables the fast graphical frontend. Use this only when having graphical problems like flickering
/noglddraw Don't use DirectDraw to setup OpenGL renderers. Try this if you're having problems getting OpenGL to work.
/safeGL Don't use possibly buggy optimized features of OpenGL for rendering. Try this if you're having problems getting OpenGL to work.
/pilotview Enable pilot view. Focus on single ship and press Q to toggle.
/heap BYTES Allows the game to use up to BYTES bytes RAM for the heap since by default the game isn't allowed to use much.

256 MB should suffice: /heap 268435456 but if you have more, try raising it to 1 GB: /heap 1073741824

To enter command line parameters in Windows 10, create a shortcut to the application and place the command line parameters outside the quotes for the path name to the right. Use the oldest compatibility that permits the game to launch (test this first) e.g. Windows Vista SP3.

Widescreen resolution[edit]

Widescreen can be enabled by changing the ScreenHeight and ScreenWidth registry keys in HKEY_LOCAL_MACHINE\Software\Sierra On-Line\Homeworld

For Windows 10 x64 you need to be run the program as Admin for the registry entries to be created (right click properties on the application under compatibility set run as administrator).[citation needed]

Set resolution in registry[citation needed]
  1. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Sierra On-Line\Homeworld
  2. Edit the ScreenHeight and ScreenWidth values to match your chosen resolution.
  3. If the resolution doesn't take effect after doing the above, try running the game in Administrator mode.
To get to the registry editor in Windows 10, in the Start Menu select Windows Administration Tools then Registry Editor. The registry entry defaults to hexadecimal so double check the decimal representation of the resolution you select. 3840 by 2160 may be possible, but the menu scale is tiny and mean time to failure shorter than 1920 by 1080.


Add -window to the game's path. For borderless fullscreen windowed mode add -noBorder as well. If you do not use -noBorder you must run the game at less than maximum screen resolution or it will crash.

Issues fixed[edit]

"Invalid or missing Homeworld CD - Please insert CD"[edit]

Install the 1.05 Patch and download a no cd crack before playing without cd.

Hardware Acceleration[edit]

Using OpenGL or D3D (in the video options) enables hardware acceleration, which gives you 32-bit colour, and the ability to use graphics techniques invented since the game's release. Hardware Acceleration works best on Windows XP or later when the game is run using compatibility mode for Windows NT 4.0. For Windows 8 and 8.1 only use the Homeworld hardware acceleration fix to apply this compatibility mode on Windows 10 the compatibility mode was added on the latest update.

Windows 8 hardware acceleration[edit]

On Windows 8 the "Windows NT 4.0" compatibility mode is no longer listed, and no other modes manage to get OpenGL working; D3D mode works, but bugs out at non-default resolutions.
Apply the fix
  1. Download the Homeworld hardware acceleration fix.
  2. Extract it anywhere and run install.bat.
  3. The game now runs in Windows NT 4.0 compatibility mode so hardware acceleration works correctly.

  1. When running this game without Administrator elevation, 32-bit programs writing to HKEY_LOCAL_MACHINE\SOFTWARE will be redirected to HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\SOFTWARE\Wow6432Node (more details).
  2. 2.0 2.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/244160/ in addition to or instead of this directory. The app ID (244160) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
  3. When running this game without elevated privileges (Run as administrator option), write operations against a location below %PROGRAMFILES%, %PROGRAMDATA%, or %WINDIR% might be redirected to %LOCALAPPDATA%\VirtualStore on Windows Vista and later (more details).
