Packet Captures

A PCAP (Packet Capture) is network data collected during an active client session to provide more concrete information for the developers to track and squash bugs

PCAPs are an invaluable tool to see behind the graphics in to what is actually occurring.

Download ACLog

  • Make a copy of your Asheron’s Call folder next to your existing folder (not inside)
  • Place the msxml4.dll in the new folder
  • Open Thwarglauncher and click Open User File
  • Find the specific account for the server you’re testing
  • Add a LaunchPath pointing to the new acclient location – The top of the UserFile details the LaunchPath syntax

If you do not do the above the packet logger will open for every single client/world you log in to, causing a mess of packet logs in your main folder.

When you come across a bug in game while the packet logger is running, please type in chat “PCAP BUG” so the timeframe can be narrowed down.

Either exit the client or hit Stop on the packet logger and a new file will be created in the AC folder with the format “pkt_YYYY-MM-DD_TIMESTAMP”

Provide this file along with your bug report.

Happy 19th Anniversary, Asheron’s Call!

November 2nd, 1999 – November 2nd, 2018…

Nearly two years after shutdown, ACEmulator is still going strong, making progress and improving week to week! Today we mark the 19th anniversary of the portals opening to Dereth with a few minor “events” in our emulated worlds.

Make sure you download the latest version of the world database and update your local copy to experience some of the “classic” moments of past anniversaries, but don’t wait too long as these events are time limited!

Welcome to our new site!

Thanks due in no small part to Miach, we’re excited to announce the opening of ACEmulator’s new home on the web!

Initially, our goals for the website are to use it to host monthly progress reports of our activities as well as any announcements along the way.

As we near closer to stable releases we might expand out the site’s scope a bit to include documentation or how-to’s on installing, configuring and administration of ACEmulator servers, but as we’re mostly not web-devs, we’re going to start small and go from there!

Please pardon the dust as we get settled in and up to speed!

Handy links to the website are: and

P.S. If you’ve got experience working with WordPress based sites and would like to contribute to ours, we absolutely would welcome help in this arena as most of our time is taken up by coding the emulator. Join or stop by our Discord server and message us your interest today! ——————>

ACEmulator News! Entity Framework + New Discord + Physics!

Hey everyone, thanks for your support and continued efforts over the past year. We’ve made some great progress and are more committed than ever to bring to the community an open source emulator.

Firstly, we’ve moved to a new discord. Any new emulator/development discussion from the core team will be handled there:

Additionally, we’ve made some great improvements with our code base. The new code should be much more developer friendly. We realized there were significant performance issues with the previous code. In addition, the complexity was over burdensome for new developers to participate in.

We’ve switched to .net core 2.0.

  • Performance increases.
  • Improved cross-platform support.
  • Exposes developers to the newest .net technologies that they may find in the real world.

We’ve switched our database model to Entity Framework Core 2.0.

  • Switches ACEmulator to popular, well documented ORM framework.
  • Significant performance improvements.
  • Scaffolding support greatly reduces the burden of adding tables/fields to the database.


If you’ve been following our commit history, you’ll notice that gmriggs has taken it upon himself to implement the physics model for ACEmulator. The goal is to have a physics engine that very closely represents what the client is doing/expecting. So far his progress has been amazing!

ACLogView has been overhauled.

ACLogView, originally developed by tfarley, is the invaluable tool we use to view pcap data collected during the massive ACEmulator community effort in December 2016 – January 2017. Slushnas has spent a great deal of time improving ACLogView, it’s parsing accuracy as well as included documentation to make it easier than ever to bring back the world of Dereth.

We’ve made a lot of progress over the last year and hope to continue that momentum!

We’re always looking for new developers. With the recent changes to our code base, it should be easier than ever for new developers to get involved!

ACEmulator Core Goals

  • Reproduce Asherons Call as it existed as of January 2017.
  • Produce an emulator engine that is both performant, but easy to understand and develop for.
  • Encourage community participation and involvement in the project.
  • Use patterns/practices/technologies that developers may find themselves exposed to in the real world.

Thanks for the support!

Gone but not forgotten…

Sadly, it’s been one year since Asheron’s Call was shut down by Warner Brothers and Turbine but at the same time, it’s also been one year since the community banded together to ensure the game continues to exist in some form or another for as long as the internet continues to have life.

We may have temporarily lost access to our original characters but the future for Dereth is bright and continues to improve day by day and week by week!

Join us in helping keep Dereth alive for decades to come by visiting our Discord and GitHub today!

To the data collectors…

I want to sincerely thank each of you for all your efforts this past month to collect the data we need to rebuild Asheron’s Call… It’s been a massive undertaking and we’ve already collected so much of the data that represented the heart and soul of what we’ve all enjoyed over these past 18 years. You’ve all done a truly phenomenal job thus far and I look forward to continue working with those already here now, and those yet to find us, as we undertake perhaps Asheron’s most difficult quest yet… Returning to Dereth!
