<p><strong>dhewm3</strong> is a source port of the original Doom3 (<strong>not</strong><em>Doom3 BFG</em>, for that you may want to try <ahref="https://github.com/RobertBeckebans/RBDOOM-3-BFG/">RBDoom3BFG</a>). It's known to work on Windows, Linux, macOS, <ahref="https://freebsd.org">FreeBSD</a>, <ahref="https://openbsd.org">OpenBSD</a> and <ahref="http://www.aros.org/">AROS</a>, but it should work on (or be easily portable to) any system that supports OpenGL 1.4 with <ahref="https://en.wikipedia.org/wiki/ARB_assembly_language">ARB shaders</a>, <ahref="http://libsdl.org">SDL</a> and <ahref="http://openal.org">OpenAL</a>.<br/>
Compared to the original version of Doom3, dhewm3 has many bugfixes, supports EAX-like sound effects on all operating systems and hardware (via <ahref="http://openal-soft.org/">OpenAL Softs</a> EFX support), has much better support for widescreen resolutions and has 64bit support.</p>
<p>It only supports <strong>old Mods</strong> if they <em>either</em> don't require their own game DLL <em>or</em> have been ported to dhewm3 - see the <ahref="./mods.html">Mods page</a> for more information.</p>
<p>Note that while the Doom3 source code has been released under GPL, you still need to legally own the game and provide dhewm3 the game data to play. See the <ahref="#how-to-install">How to Install</a> section for more information.</p>
<h4id="a-first-prerelease-of-dhewm3-1.5.1">2019-03-11: <em>A first prerelease of dhewm3 1.5.1</em></h4>
<p>There are no immediate plans for the final 1.5.1 release, but the current status might be interesting :-)</p>
<p><ahref="./dhewm3-edit.jpg"title="DOOMEdit running in dhewm3"><imgsrc="./medium-dhewm3-edit.jpg"style="max-width:90%;margin-left:auto;margin-right:auto;display:block"></a></p>
<p><strong>Changes since 1.5.0:</strong></p>
<ul>
<li>The (Windows-only) integrated <strong>editing tools</strong> of Doom3 are back!
<ul>
<li>They can only be built with non-Express versions of Visual Studio (tested Community Editions of VS2013 and VS2017) and can be disabled via CMake</li>
<li>The <ahref="https://github.com/dhewm/dhewm3/releases/tag/1.5.1_PRE1">dhewm3_1.5.1pre1_win32.zip available on Github</a> has them enabled, of course
<ul>
<li>While prior dhewm3 releases have been built with Visual Studio 2010, this is built with Visual Studio 2013, so if it doesn't start on your system make sure you have <ahref="https://www.microsoft.com/en-us/download/details.aspx?id=40784">the Visual C++ 2013 Redistributable</a> installed - but chances are good you already have it.</li>
</ul></li>
<li>Only tested in 32bit builds, in contrast to the rest of dhewm3's code, the tool code might not be 64bit-clean</li>
<li>Based on Code from the dhewm3 branch of SteelStorm2, thanks to Motorsep for donating that code!</li>
<li>Has some bugfixes over the state in Doom3 1.3.1, like selecting a material in the Particle Editor doesn't break the viewport of the game any more.</li>
</ul></li>
<li>dhewm3 now supports the <strong>Doom3 Demo</strong> gamedata (<ahref="https://www.fileplanet.com/archive/p-15998/DOOM-3-Demo">D3Demo.exe</a> or <ahref="http://files.holarse-linuxgaming.de/native/Spiele/Doom%203/Demo/doom3-linux-1.1.1286-demo.x86.run">doom3-linux-1.1.1286-demo.x86.run</a>)
<ul>
<li>On Windows, just run D3Demo.exe to install the demo, on Linux (and probably others) you can extract the relevant file from the .run installer with <code>sh doom3-linux-1.1.1286-demo.x86.run --tar xf demo/</code></li>
<li>This is based on Gabriel Cuvillier's code for <ahref="http://www.continuation-labs.com/projects/d3wasm/">D3Wasm</a>, which ports dhewm3 to web browsers, thanks!</li>
</ul></li>
<li>(On Windows) stdout.txt and stderr.txt are not saved next to the binary anymore, but in <code>My Documents/My Games/dhewm3/</code>, like save games, because the binary dir might not be writable and dhewm3 wouldn't start properly then</li>
<li>Support for <ahref="./mods.html">some Mods</a> via <ahref="https://github.com/dhewm/dhewm3-sdk">custom SDK</a>: Classic Doom3, Fitz Packerton, HardQore2, Denton's Enhanced Doom3 and Rivensin (formerly known as Ruiner).
<li><ahref="https://github.com/dhewm/dhewm3/releases/download/1.5.0/dhewm3_1.5.0_win32.zip">dhewm3-mods_1.5.0_win32.zip</a> contains prebuild Windows game DLLs for those Mods (except Rivensin) and a README that tells you where to get the game data</li>
<li>See <ahref="./mods.html">the Mods page</a> for more information.</li>
<li>This has also broken backwards compatibility with 1.4.x game DLLs, that's why this version will be 1.5.0 and not 1.4.2.</li>
</ul></li>
<li>Supports High DPI displays on Windows now</li>
<li>Scale menus, fullscreen videos and the PDA to 4:3 (with black bars left/right) on widescreen displays so they don't look stretched/distorted. Can be disabled with <code>r_scaleMenusTo43 0</code>.<br/>
No, this unfortunately can't be done for the HUD (except for the crosshair), because it also handles fullscreen effects (for example when receiving damage), and those would look bad with black/empty bars on left/right.</li>
<li>Commandline option to display some help on supported commandline arguments: <code>-h</code> or <code>--help</code> or <code>-help</code> or <code>/?</code></li>
<li>(Experimental) uncapped framerate, enable by entering <code>com_fixedTic -1</code> in the console (can be set back with <code>com_fixedTic 0</code>).</li>
<li>Providing binaries for Linux amd64 (x86_64) now
<ul>
<li>Should work on any halfway-recent distro, needs <code>libSDL2-2.0.so.0</code>, <code>libopenal.so.1</code> and <code>libcurl.so.4</code> installed</li>
<li>Updated some libraries bundled in the Win32 build: <ahref="https://libsdl.org">SDL2 2.0.9</a>, <ahref="https://openal-soft.org/">OpenAL-soft 1.19.1</a> and <ahref="https://curl.haxx.se">curl 7.62.0</a></li>
<p>I guess it makes sense to be a bit less dependent on Github (especially as it has been bought by Microsoft, but also in general), so I decided to create this homepage with a domain I control.<br/>
Another advantage is that it has some screenshots and more user-centric documentation than the <ahref="https://github.com/dhewm/dhewm3/blob/master/README.md">README.md</a>.<br/>
We'll continue to use Github for hosting the code and issues (and indeed this page via github pages), but if we need to migrate to another hoster some day, <ahref="http://dhewm3.org">dhewm3.org</a> will still be reachable and will link to the new code repo and issue tracker instead.</p>
<li>Fixed some (kinda rare) crashes due to assertion errors, especially observed in the last boss fights of both doom3 and the Resurrection of Evil Addon.</li>
<li>Improved compatibility with AZERTY keyboards (the row of keys with 1...9, 0 is now usable)</li>
<li>Fixed a crash (at least on FreeBSD) when loading Resurrection of Evil's last level</li>
<li>Compatibility with Microsoft Visual Studio 2015</li>
<li>Video resolutions in menu now sorted, added 2880x1800</li>
<h3id="from-cddvd-patch">... from CD/DVD + Patch</h3>
<p>If you bought the game on CDs/DVD, base/pak000.pk4 - pak004.pk4 and d3xp/pak000.pk4 can be copied from the disks, the other files are from the patch.</p>
<p>On <strong>Linux</strong> (and probably other <strong>Unix-like</strong> systems and maybe even Windows with a mingw shell) you can extract the needed files from <ahref="https://files.holarse-linuxgaming.de/native/Spiele/Doom%203/doom3-linux-1.3.1.1304.x86.run">the official 1.3.1 patch for Linux</a> with:</p>
<p>On <strong>Windows</strong> you can just install the game and <ahref="https://archive.org/details/Doom_3_1.3.1">the official 1.3.1 patch for Windows</a> and then get the files from the installation directory (or copy dhewm3 in there).</p>
<h3id="from-steam">... from Steam</h3>
<p>First you need to buy <ahref="http://store.steampowered.com/app/9050/">Doom3</a> of course (and the <ahref="https://store.steampowered.com/app/9070/">Resurrection of Evil Addon</a>, if you want that too; Note that the Addon is not available in Germany).</p>
<p>Thankfully the game from Steam is already fully patched to 1.3.1.</p>
<p>On <strong>Windows</strong>, <em>just install</em> it and copy the game data from there (see above for what files are needed).</p>
<p>On <strong>Linux/OSX</strong> unfortunately you can't just install the game (unless you run Windows Steam in Wine), because it's Windows-only on Steam.<br/>
However, you can still download it with <strong><ahref="https://developer.valvesoftware.com/wiki/SteamCMD">SteamCMD</a></strong>.<br/>
See <ahref="https://developer.valvesoftware.com/wiki/SteamCMD#Linux">this description for Linux</a> or <ahref="https://developer.valvesoftware.com/wiki/SteamCMD#OS_X">here for OS X</a> on how to install SteamCMD on your system. You won't have to create a new user.</p>
<p>(replace <code><YOUR_STEAM_LOGIN_NAME></code> with your steam login name)<br/>
When it's done you should have the normal windows installation of doom3 in <code>./doom3/</code> and the needed files in <code>./doom3/base/</code><br/>
It should be possible to get the <em>Resurection of Evil</em> data in the same way, by replacing <code>9050</code> with <code>9070</code>; the files should be in <code>./doom3/d3xp/</code> then.</p>
<p>By the way, that number is the "AppID" of Doom3/RoE; if you wanna use this to get the data of other games you own, you can look up the AppID at <ahref="https://steamdb.info/">SteamDB</a>.</p>
<p>On <strong>Windows</strong> you can just download the Win32 binaries from the <ahref="https://github.com/dhewm/dhewm3/releases/latest">Download page</a>.<br/>
You can either extract them into your Doom3 installation directory, or into a fresh directory and copy the needed game data (<ahref="#getting-the-doom3-game-data">see above</a>) in there.<br/>
Similarly, you can find x86_64 (amd64) <strong>Linux</strong> binaries there.</p>
<p>On Linux and *BSD it might be that your package manager provides a dhewm3 package/port that you can install; please refer to that packages documentation on where to put the game data.<br/>
You could also try telling dhewm3 where to find the game data with:</p>
<p>If your package manager does not provide dhewm3 (or you're on macOS/OSX and there is none), or you want to use the very latest code, you'll have to compile it yourself. It's not super hard, see <ahref="https://github.com/dhewm/dhewm3/blob/master/README.md#compiling">the README</a> for details on compiling and <ahref="https://github.com/dhewm/dhewm3/wiki/FAQ#where-do-i-need-to-put-the-game-data-files">the FAQ</a> on where to put the game data.</p>
