# ReHLDS [](https://github.com/dreamstalker/rehlds/actions/workflows/build.yml) [](https://github.com/dreamstalker/rehlds/releases/latest) []() [](http://isitmaintained.com/project/dreamstalker/rehlds "Percentage of issues still open") [](https://www.gnu.org/licenses/gpl-3.0) <img align="right" src="https://user-images.githubusercontent.com/5860435/111066129-040e5e00-84f0-11eb-9e1f-7a7e8611da2b.png" alt="ReHLDS" />

Reverse-engineered (and bugfixed) HLDS
|
|
|
|
## What is this?
|
|
ReHLDS is a result of reverse engineering of original HLDS (build 6152/6153) using DWARF debug info embedded into linux version of HLDS, engine_i486.so
|
|
|
|
Along with reverse engineering, a lot of defects and (potential) bugs were found and fixed
|
|
|
|
You can try play on one of the servers that using rehlds: [Game Tracker](http://www.gametracker.com/search/?search_by=server_variable&search_by2=sv_version)
|
|
|
|
## Goals of the project
|
|
<ul>
|
|
<li>Provide more stable (than official) version of Half-Life dedicated server with extended API for mods and plugins</li>
|
|
<li>Performance optimizations (use of SSE for vector math for example) is another goal for the future</li>
|
|
</ul>
|
|
|
|
## How can use it?
|
|
ReHLDS is fully compatible with latest official HLDS downloaded by steamcmd. All you have to do is to download rehlds binaries and replace original swds.dll/engine_i486.so. For windows you can also copy a swds.pdb file with a debug information.
|
|
<br /><b>Warning!</b> ReHLDS is not compatible with an old 5xxx or below platforms downloaded by hldsupdatetool.
|
|
|
|
## Downloads
|
|
* [Release builds](https://github.com/dreamstalker/rehlds/releases)
|
|
* [Dev builds](https://github.com/dreamstalker/rehlds/actions/workflows/build.yml)
|
|
|
|
ReHLDS binaries require `SSE`, `SSE2` and `SSE3` instruction sets to run and can benefit from `SSE4.1` and `SSE4.2`
|
|
|
|
<b>Warning!</b> ReHLDS is not binary compatible with original hlds since it's compiled with compilers other than ones used for original hlds.
|
|
This means that plugins that do binary code analysis (Orpheu for example) probably will not work with rehlds.
