dhewm3
A Doom 3 GPL source modification
dhewm3
Description
dhewm3 is a source port of the original Doom3 (not Doom3 BFG, for that you may want to try RBDoom3BFG). It's known to work on Windows, Linux, macOS, FreeBSD, OpenBSD and AROS, but it should work on (or be easily portable to) any system that supports OpenGL 1.4 with ARB shaders, SDL and OpenAL.
Compared to the original version of Doom3, dhewm3 has many bugfixes, supports EAX-like sound effects on all operating systems and hardware (via OpenAL Softs EFX support), has much better support for widescreen resolutions and has 64bit support.
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.

Install
Channel stable v1.5.1-2
This app is curated in HaikuPorts. Install it from there, it is already available in HaikuDepot.
pkgman install dhewm3
Careful: the file comes from HaikuPorts' own server, but installing it by hand is not the way in. It is pkgman that resolves the dependencies an .hpkg does not carry with it, and a package installed on its own may simply not run. Use the pkgman command above, unless you know exactly why you want the file.
