SourceModPatcher v0.0.0 has been released.
A video has been made to show the Quick start guide.
Note: I forgot to show 1187: Rogue Train patched but the mod installation guide explains how to install and configure SourceModPatcher to fix it. It's been tested:
Reporting issues
Please report any issue on GitHub (preferably) :
Issues may also be reported in the comments here as long as it's short. If you need to provide a lot of detail and or share error logs, please send me a PM.
Additional notes
- The program is based on .NET but is meant to be self contained. You shouldn't have to install any framework.
- There is no Linux version planned. Almost if not all old HL2 mods were only playable under Windows so there's currently no reason to make it cross-platform.
- Singleplayer mods are foremost prioritized. Multiplayer mods might eventually be added for preservation but it will likely be limited to only making them launchable and won't have further fixes since it requires extra maintenance, testers, setting up servers, etc.

Half-Life Unified SDK
In this article, I explained that I have been contributing to Half-Life Unified SDK.
All mandatory work is done.
I would like to inform that the project's first version (1.0.0) has recently been released.

- Gamepad UI support for older source mods (proof of concept)
In 2022, Half-Life 2 games were updated. The update added a new UI (Gamepad UI).
That year, before my return to studies, I quickly worked on a proof of concept to see how it would look like for older Source mods.
This presentation shows the mod 'Ravenholm' running under Half-Life 2 (Not Source SDK Base 2013) with custom Gamepad UI graphics to match the original mod's theme.
As explained in this article, I planned to revisit the Source SDK Base 2013 patches. The Source SDK Base 2013 does not officially implement support for the new UI but according to the following below, there is potentially a possibility to be able to integrate it.
Developer.valvesoftware.com
Github.com
If it's not possible, the mod would have to run under the base game.
One way or the other, if I come to revisit the Source SDK Base 2013 patches, would you be interested in custom Gamepad UI graphics as seen in the presentation ?
Let me know what you think.
In 2013, SteamPipe content distribution system was introduced in Source games. Source games were updated to use this new system. This made many older mods unplayable due to the older mounting mechanism incompatible with SteamPipe's mounting mechanism. It is possible to get pre SteamPipe Source mods working again but this requires a lot of manual fixes and adjustments.
Lately, I have been working on two tools that can do the work automatically. See the following:
The presentation shows a preview of the tools and nine pre SteamPipe Source mods (before and after fixes). Note that this is a WIP. In each mod, not all areas and or cases are yet covered and reviewed.
I still have a couple of unit tests to write and retest all mods shown in the presentation. After that, I'll make the repository public and release a first build of the tools.
2022 summary
2022 has been a busy year.
From late December 2021 up to now, I have been mainly contributing to Half-Life: Unified SDK. The project is still in pre-alpha but you can check the releases if you wish to try.
Aside from a couple of contributions in code, I have mostly been updating models to allow them to work across all 3 campaigns. Several meshes, textures, UVs were reworked so that they could be reused across models whenever possible. Various mesh and animation quirks were also fixed. See 'Additional information' at the end for more details.
So far, all major work related to models that's required to play through all campaigns is expected to be complete but there are a couple of minor improvements/adjustments that still remain for which I'll try to address in my spare time. Note that due to my return to studies, this is likely to occur only between sessions.
Source SDK 2013 patches
I have been asked if I would continue work on Source SDK 2013 patches.
Prior to a few months ago, I had considered eventually reviewing all existing patches and improve/fix issues. This was originally to occur after finishing modeling work for Unified SDK but due to my return to studies these plans are currently on hold.
Additional information
While adjusting models, various challenges arise. For example, HL1 and Blue Shift scientists models have different bone hierarchy, names, length, etc. incompatible skeletons. This required developing utilities to retarget animations onto a different target skeleton, uniformly, adjusting bone lengths and doing other operations in the process.
Although the tool was made for a one time use, it has been sufficiently flexible so that I was able to add specific animations (originally exclusive to certain models) to other models that have similar bone structure e.g.
- HL1 grunts <-> Op4 grunt allies <-> Male Black Ops
- HL1 scientist <-> Cleansuit scientist
- Barney <-> Otis
This should give mappers the chance to use shared animations in different ways.
As of September 2022, due to professional objectives and endeavors I returned to University to continue my studies in Computer Science, part time.
I had previously attended University back in 2014-2015 but decided to leave for various reasons, notably insufficient grades. I am currently under conditional admission and have to fulfill criterias.
Since then, I have completed a college diploma (2018) and various courses were credited, therefore increasing the overall progression. Here a bachelor is comprised of a total of 30 courses (internships excluded). After the current session, I will have the equivalent of 15 courses done.
So far things are going as planned but there will be uncertainty at least until fulfillment of conditional admission. I will update the current blog when possible regarding this matter.
Until then, I will be away for an undetermined amount of time. I might occasionally check for new comments/questions but I will not have time to address technical issues.
This is to inform that all Half-Life mod SteamPipe patches, now referred to as Half-Life mods reimplementations, have been updated. A lot of restructuring has been made within the code.
For each project:
- Source code has been reviewed and reworked for some parts
- Almost if not all features were retested
- All found issues were fixed
In addition, all mod source code have been moved to their own repository. Please report issues at the corresponding project repository. Issues reported in the comment section are still accepted.
Remember, the releases do not include the full mod. You must install each original mod, and apply the Release files onto the original mod files.

Times of Troubles
Over the years, I created many 'Steampipe patches' for various Half-Life mods. The Steampipe patches are not actual ports of the original source code of those mods, but re-implementations from scratch made to reproduce as closely as possible the behavior found in the original mods. Some of the original Half-Life mods with custom compiled code feature entities with little to no changes and were easier to reproduce, while other mods such as Poke646 feature more complex entities/NPCs that were harder to reproduce. The behavior found in the re-implementations was not 100% accurate, but an approximation.
The goal of these re-implementations was to be able to sufficiently reproduce the behavior of mods, fix bugs that possibly existed in the original mod release through re-implementation, and provide source code to allow people interested in expanding those mods, the chance to do so.
Recently, I found out that several mods for which I made a 'Steampipe patch' have been reverse engineered. Reverse engineering is a difficult subject for which I am not really knowledgeable, but when done correctly with the appropriate tools, and with sufficient understanding on the subject, it is possible to 'rewrite' source code using information extracted by decompilation; disassembly; etc. In the context of a Half-Life mod, and assuming all entities and custom game logic have been correctly reverse engineered, the resulting behavior is almost, if not, 100% identical to the one found in the original mod.
In contrast to my 'Steampipe patches' which currently only work on Windows and are 'approximations' of the behavior of original mods, the reverse engineered mods have been made cross platform and likely offer a better, if not, exact replica of the behavior found in their associated mod. For these reasons, and also because they can provide a better; closer experience to the original mods, I made the decision to archive my 'Steampipe patches', precisely the ones that have been reverse engineered and or have been made cross platform. It implies that I will no longer be providing support for these patches, as from now on I will be recommending users to download the reverse engineered cross platform ones.
The source code for my Steampipe patches will remain available on my Github repository for people that might still be interested in using it.
I requested the removal of the Blue Shift: Unlocked Steampipe patch, and the patch has been removed.
The reason for removing is due to potential infringement of Gearbox's EULA. Please note that I am not a lawyer, but I have been reading several notes about Steam and Gearbox's EULA and there are a few things that I wish to highlight.
It is important to note that Half-Life: Blue Shift is a game developed by Gearbox Software. Therefore it is Gearbox's intellectual property. According to Gearbox's EULA, it is prohibited to 'reproduce', as well as prepare 'derivative works' based on any game developed by Gearbox. Again, I am not a lawyer but from my understanding, it appears that Blue Shift: Unlocked would represent a kind of 'derivative work'. This means that the Steampipe patch I created being a re-implementation of Blue Shift: Unlocked also constitutes, by definition, a 'derivative work'.
Secondly, one thing to note in Half-Life: Blue Shift is that the file format differs from the original Half-Life file format. Back when I was working on the Steampipe patch of Blue Shift: Unlocked, I found a website detailing the differences between the file formats of the original Half-Life and the one from Blue Shift. Despite the two file formats are 99% identical, the reason for this slight difference is unknown. The thing to note is that I wrote a tool to convert Blue Shift maps files to Half-Life maps. According to Gearbox's EULA, doing such thing also seems to be prohibited.
A few years ago, I was asked about the release of the source code for the tool I wrote that allows to convert Blue Shift map files to the Half-Life map format, but since I was unsure what was Gearbox's rules and restrictions on such tool, I emailed Gearbox Software, asking for the permission to release the source code of my tool. I never received a reply regarding this subject, and simply kept the tool closed source. The discussion I had is what started me to think about potential legal issues. As time went on, I went more and more concerned about this subject, and I recently decided that I would simply remove my Steampipe patch for Blue Shift: Unlocked, as I want to avoid being at risk of pursuits.
Back then, I was not thinking about these details as much as today, and I wish to take the time to apologize to Gearbox Software for any infringement that could have potentially been made by the making of the Steampipe patch.
Finally, in the past, I made several other projects including an unfinished re-implementation of Half-Life: Opposing Force, as well as a re-implementation of Half-Life: Blue-Shift, possibly unfinished too. Due to the reasons of potential infringement to Gearbox's EULA, I also removed these projects and decided that I will wait until Gearbox publishes an official statement regarding the use of their intellectual property in Goldsource mods before making these projects available again.
Here is the list of projects that have been removed:
- Github.com - Steampipe patch of Blue Shift: Unlocked
- Github.com - Re-implementation of Half-Life: Blue Shift (possibly unfinished)
- Github.com - Unfinished re-implementation of Half-Life: Opposing force
- Github.com - Same as unfinished re-implementation of Half-Life: Opposing force, but with Visual Studio 2017 support
Until Gearbox releases an official statement about the use of their intellectual properties in Goldsource mods, I recommend anyone currently using content from the repositories and branches listed above, to stop using this content, as the use of such source code may be risky according to Gearbox's EULA.
Context
This article is a follow up to my previously written article, which can be found here. If you wish to get a better grasp at my current situation and why I am currently writing this article, feel free to read.
Many months have passed without any proper news released about the Half-Life 1/2 Unreal engine 4 port that I considered attempting to do in my spare time. I do feel embarrassed to write these words because I stated I would let know about the status of the project, regularly.
As stated in my last article, I graduated, found a work and am now working full time. I really love the work I do and I pour a lot of energy into my work. When I get home, I have very few energy left to put into game modding.
Lately, I began having less and lesser motivation to work on projects such as porting HL1/HL2 to Unreal engine 4, coding patches for HL1/HL2 mods. This could be potentially due to the fact I have few spare time, now that I have a work, have more responsibilities and am taking driving lessons in parallel. This loss of motivation could also be happening because I have been playing those games for a long time and am simply bored and looking to try out new experiences.
I am writing this to let anyone following my blogs know that it is impossible for me to tell when I will continue working on these projects. It may or may not happen.
I will still remain active from time to time to answer any question people might have.
Sincerely,
malortie.
