Homeworld is a 3D space real-time strategy game released in 1999. Its source code was released in 2003 by Relic Entertainment, allowing a small but dedicated community of fans to port it to SDL.


This repository contains only the source code for Homeworld's engine (metaphorically, the skeleton). In order to have a playable game, you will need the original assets (artwork, textures, sounds, meshes, ... Metaphorically again, the flesh).

So make sure you have:

• The Homeworld CD
• The 1.05 Patch

Asset checklist

To sum it up, here are the files required for the game to run:

• Homeworld.big

• HomeworldSDL.big (This file should be included in the [releases])

Usually you will find these files in your installation folder. For more detailed instructions, read on.

Extracting game assets with wine

Install the game and patch with wine (tested with wine 4.1)

wine HWSetup.EXE
wine si_homeworld_update_105.exe

Open the game installation folder (usually ~/.wine/drive_c/Sierra/Homeworld). This is where you'll find the required files.

Installing the binary distribution

1. Download [the latest release][releases]. (Extract it if necessary)
2. Copy the files you gathered earlier in the folder you just downloaded
3. Run the game
4. Jump to Configuring the OpenGL renderer

Compiling from source

Please refer to IRIX/BUILD.md.

Configuring the OpenGL renderer

The first time you run the game, you'll have to configure the renderer to use OpenGL. This will be saved in your ~/.homeworld, so you won't have to do it every time you run the game.

Once the game has launched, you need to:

• Select "Options" from the main game menu.
• Select "Video" from the available option sub-menus listed on the right side of the screen.
• Select "(GL) Default OpenGL" from the "Rendering System" box.
• Choose a resolution from the "Resolution" box (any resolution you choose will do fine).
• Click on the "Accept!" button in the bottom-right corner of the screen.

The game will now attempt to switch to the OpenGL renderer.
If everything goes okay, you should be presented with a confirmation that the settings you requested were changed. Select "Yes", and you should be ready to go!
