Recently, milestone started working on some tools for Warcraft II: PudForge and RuneFoundry.

PudForge is a very competent map editor. The map format is the same in the original DOS versions of Warcraft II as well as the Battle.net Edition and the more recent Remastered version. PudForge thus works for all of them. The author, milestone, has made a video showing the features, and it has some really nice capabilities. I was especially impressed with the terrain editing, as the editor supports copying and pasting terrain, replacing a given terrain type with other types, generating maps, drawing symmetrical shapes and much more.

RuneFoundry is a set of mod tools for Warcraft II Remastered only — not the DOS originals or Battle.net Edition. It has two programs, a mod launcher and an editor. A video showing its features is available here along with a video of an example campaign which plays through a campaign made with RuneFoundry. It can edit things like the campaign, AI-scripts, sprites and unit and weapon properties.

It is fantastic to see such feature rich and capable tools still being put out! Hats off to milestone for the efforts!

I just saw that Thomas Laurenson made a new release of mpqcli earlier this week. Many of the changes are things I contributed a while back, that has now made it into release 0.11.0. mpqcli is a command-line tool to create, add and remove files from MPQ archives. MPQ archives were used for many years by Blizzard games such as StarCraft I and Warcraft II, and contain the game assets that game modifications change.

I'd like to highlight a few of the changes that I contributed to this release:

• A rename subcommand has been added, which allows you to rename a file inside an archive without having to remove and re-add it.

• The logic for updating files in an archive has been improved. When working on archives containing the (attributes) file, mpqcli will now — if the --update flag is given — compare timestamps and checksums in addition to just file size when deciding whether to update a file. This means that it will much more quickly decide whether a file needs to be updated or not, and will avoid unnecessary writes to the archive. This was quite an extensive change, that also involved me making some contributions to StormLib, the MPQ library that mpqcli uses to read and write MPQ archives.

Changes in mpqcli 0.11.0:

Added

• Add rename subcommand to rename a file inside an archive

Changed

• Compare timestamps and checksums when updating files, not size alone
• Accept the --update flag for single files as well as directories
• Reject the --update and --overwrite flags on add when both are given

Fixed

• Report filesystem errors instead of aborting when a path cannot be resolved
• Add to and create archives on volumes that cannot report real paths
• Block path traversal in extract before anything is written to disk

Updated

• Update StormLib for a variety of fixes
• Add hash-library as a submodule dependency
• Build with StormLib's bundled compression libraries instead of system packages
• Require CMake 3.25 or later

Yesterday, TheNitesWhoSay released version 2.15 of the StarCraft I map editor Chkdraft.

It is a smaller release with three changes:

• The submenu tools/scripts now has a script to downgrade maps from remastered
• Support for new cosmonarchy weapon limits
• Better logging/debugging/browsing when dat file loading has issues

Version 2.15 is available here.

I am probably the last person interested in Blizzard games to hear this, but BlizzCon 2026 wrapped up a week ago. It was last held in 2023, so it's been a while.

There are some announcements for the Warcraft and StarCraft franchises:

• Warcraft III gets its first new campaign in over 20 years: "Return to the Last Days of Lordaeron to experience the fall of one great city and play a part in the founding of another". Blizzard released a Launch Trailer, which seems pretty close to the original intro of Warcraft III from back in the days: two armies clash in futile strife, as the real threat appears from above. A gameplay trailer can be seen here. It is already available from Blizzard.

• Blizzard is working on a new StarCraft game! It is an open world, first person shooter that is apparently single player and character focused. The Announce Cinematic is pretty gorgeous, but there seems to be no gameplay footage available, and the game is set to be released in 2030; offering "plenty of time for delays". For a deeper dive into what the game might be like, I enjoyed GameDad VII's analysis.

For me, it certainly sparks excitement to experience the StarCraft universe from this angle. Of course, Warcraft III from 2002 and the new upcomming StarCraft game of 2030 are both much to new for this site; Jorvik Systems is dedicated to Warcraft I, Warcraft II and StarCraft from the good ole nineties so don't expect much coverage on this site — but it's not every day that 23 year old games get a new campaign and the StarCraft universe expand into new types of games.

I released a new version of MPQDraft yesterday. MPQDraft is a modding tool that allows in-memory patching of game data files, added features through plugins, and creation of self-executing mods.

This summer, jzy-chitong56 made some Chinese (Simplified) translations for the program and suggested ways in which to make the user experience nicer for those using the translations. While it took me a while to sit down and look at it, I was happy to merge the translations, and jzy-chitong56's idea of a dynamic language switcher was much nicer than the convoluted and technical way it was handled before. I thus developed a little menu button on the Main GUI to change languages. Hopefully Joel Steudler, the graphical artist who made the interface back in the day, won't be too mad at me for slightly deviating from his 2002 work :)

Apart from the new translations and the translations menu, I made it easier to build the application under Arch Linux, and there were improvements to the CI pipeline.

For those who are happy with English and don't intend to build the software yourself, this version unfortunately doesn't bring much excitement. But perhaps that is also a testament to the fact that the original author, Quantam (Justin Olbrantz), made a pretty solid piece of software back in the day.

See the MPQDraft page here, for a download link.

In December, I wrote an MPQDraft plugin, MpqFileLister that lists all the filenames that a games accesses in its MPQ archives — or at least that was the intention. A peculiarity of MPQs are that they don't contain the file names of the content of the archives. But when accessing them, the game will call functions in Storm.dll to open those files, and by hooking into those calls, we can intercept the file it is attempting to open, thus construct a list of all files that are accessed.

I had thought that hooking into the SFileOpenFile and SFileOpenFileEx calls would be enough, but when luauser32167 pointed out on GitHub that the resulting list files were not containing all assets that the game loaded, I realized those two calls were not enough.

I have just made a new release of MpqFileLister that in addition to SFileOpenFile and SFileOpenFileEx and also hook into SVidPlayBegin, SFileLoadFile, SFileLoadFileEx, SBmpLoadImage and SBmpAllocLoadImage. I thus believe all Storm.dll functions that load files by their file names are covered.

In addition, this new release allows the user to freely specify the log format and timestamps, some odd bugs have been fixed and the code has been refactored.

You can find version 1.2.0 of MpqFileLister on GitHub.

This is still rather untested on Diablo I. I tried to test, but Diablo I is just too buggy under Wine on my machine, and I don't have access to a Windows computer. I might try to see if I can contribute to Wine and fix it eventually, but I'm not going to prioritize that for a while yet.

By the way, you might be wondering what the need then is for namebreak-cuda, which I wrote about in the previous entry. The answer is simple: not all files are accessed, but finding and naming them is still of interest.

For many years, Blizzard used MPQ files as their archive files for many of their games. MPQ files are basically like ZIP files; they store many other files in a compressed format. One quirk of MPQ files is that they don't contain the filenames of their own content. Some MPQ files contain a listfile consisting of the filenames of their content, but other MPQ files do not. For these, an external listfile is needed.

The War2Dat.mpq archive of WarCraft II: Battle.net Edition has had a 99% complete listfile for years, but there has been one single file that the community has not known the name of.

Around a year ago, I made a tool, namebreak-cuda, which bruteforces filenames on Nvidia GPUs. While I put the heavy lifting in place, I never quite finished it then. So now, after tweaking it for a bit, I ran it for less than two hours, and it returned the missing filename:

ART\CHAT_BNE_PLAIN.PCX

The War2Dat.mpq now has complete listfiles after all these years. I was happily surprised that the search was so quick.

There are other archives that also don't have complete listfiles, to which I turn my attention next. I plan to make the tool more polished, create a server which can coordinate the efforts of finding more file names, and publish the code on GitHub.

As I wrote about back in May, I've been working on scraping forums and retrieving long gone content from the Internet Archives. It has turned out to be way more fiddly than I expected, mostly because I decided to turn the HTML forum posts into valid Markdown format, and people have used and abused HTML in all sorts of ways. I hope to host the scraped content of dead sites here in not too long.

The scraper is available here for those who want to make their own backups of sites, but please remember that it takes a long time to run, and every page of every thread puts load on the webservers, so please be considerate. We don't want to push any sites further towards unmaintainability.

Some might have noticed that Campaign Creations went down recently. It was once a hugely popular site, but has for a long time been reduced to a forum (with no other content available) that was neither active nor possible to register accounts at. They went dark a few months ago, which I figured was the deathknell for the site. However, I am happy to see that they once again are alive and kicking, and at least some of the content that they used to host seems to be accessible again. And once more, you are now able to register at the forum!

Over the past few days, there's been two releases of mpqcli, and StormLib has also had a release. mpqcli is a command-line tool to create, add and remove files from MPQ archives, and StormLib is the underlying library powering it. MPQ archives were used for many years by Blizzard games such as StarCraft I and Warcraft II, and contain the game assets that game modifications change.

Changes in mpqcli 0.10.1:

Added

• Command completion for common shells (bash, zsh, fish and powershell)

Fixed

• Memory leak in read subcommand
• Inconsistencies in documentation

Updated

• Code style to conform to Google CPP style with slight variations
• StormLib dependency for a variety of fixes

Changes in mpqcli 0.10.2:

Fixed

• verify incorrectly reporting success for a tampered archive
• verify failure messages now clarify whether a signature is missing or invalid
• add overwrite flag not always working as expected
• Archive size incorrectly reported for large archives
• File sizes shown as negative for large files

Updated

• Simplified how strong archive signatures are read internally

Changes in StormLib 9.40:

The changelog for StormLib is brief and only states that it "Added functions SFileOpenFileArchive and SFilegetFileArchive", but the release is actually the accumulation of changes since November 2024.

For StarCraft I modders, one of the best set of tools has for a long time been PyMS, a graphical tool suite that allows several file types to be modded.

The author, poiuy_qwert, has been hard at work converting the source from Python 2 to Python 3, and writes:

Hey all, I've been putting a lot of work into the python3 version of PyMS recently, but again I only have time to work on the tools not to actually use them, so I need to lean on others to use/test the programs and report any issues. If anyone is able to play with them please let me know!

See here for how to raise any issues.

Also, while the source of PyMS has been available for a long time, it has so far been without any explicit license, but poiuy_qwert just now released it under the MIT license.
