Meet Our Newest App, ACViewer

ACViewer is currently a work-in-progress, multipurpose DAT file viewer for Asheron’s Call portal and cell DAT files.

With this tool today, you can view many of the objects contained within those files, including object models, particle effects, textures, images, sound files, and landblocks which include over-world landscape and dungeons.

The above pictures represent only a sample of what you can view with this application right now and there are plans for many more features to come. Eventually moving towards DAT modification and even a full-on WorldBuilder like functionally for new content development!

Click Here to download ACViewer! 

Visit the GitHub website to download this tool and explore Dereth in new ways today! You can also click on the Discord link to the left to keep up with our changes to this new app as well as our other projects. Progress is made nearly every day on all things Asheron’s Call emulation.

Stay tuned for future announcements about our first downloadable releases of ACEmulator server software, in addition to the source code repo downloads!

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! ——————>

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!

Additional Data Logging Tools

If you’re looking to help out with our data mining efforts even further then there’s four new Decal plugins available that should be added to your lineup ASAP, courtesy of Mag-nus.
