In this in-depth episode of Tech Over Tea, host Brody Robertson sits down with Braden Obazat, better known as Bielzat or Blzut3, the long-time maintainer of ECWolf and former key contributor to ZDoom. The conversation dives deep into the history, philosophy, and technical evolution of Doom and Wolfenstein 3D source ports, exploring why so many variants exist and how they’ve shaped modern modding culture. Obazat shares his journey from a simple desire to add volume controls to Wolfenstein 3D into building ECWolf—a project that now supports multiple Wolfenstein-derived games, including Super 3D Noah’s Ark and Rise of the Triad. He reflects on the complex dynamics within the ZDoom community, including his time as a maintainer, the eventual split with Graf Zal (leading to GZDoom and UZDoom), and the broader implications of open-source licensing, binary compatibility, and project governance in Linux software packaging. The discussion also touches on the cultural significance of retro game preservation, the impact of id Software’s early source code release, and the surprising career path that began with modding and led to contributions to the C++ standard and GCC. The episode concludes with Obazat’s reflections on what keeps him motivated—enabling others to create and publish games—while offering practical insights into Linux distribution challenges, the limitations of AppImage and Flatpak, and the need for better legacy support in distros. Despite the technical depth, the tone remains warm and reflective, celebrating the collaborative spirit of open-source communities even amid conflict. Obazat’s humility, technical mastery, and passion for preserving gaming history shine through, making this a must-listen for fans of retro gaming, open-source development, and software longevity.
ECWolf was born from a simple desire to add independent sound volume controls to Wolfenstein 3D, evolving into a full-featured source port supporting multiple Wolfenstein-derived games.
The proliferation of Doom and Wolfenstein source ports stems from early open-source releases, differing philosophies on compatibility and features, and the 'not invented here' syndrome common in passionate communities.
ZDoom’s success came from its player-focused design, backward compatibility, and powerful scripting (Decorate/ZScript), enabling a vibrant modding ecosystem that inspired projects like ECWolf and Zandronim.
The split between GZDoom and UZDoom was not a sign of project failure but a symptom of health—when a project grows too large for one leader, a fork becomes necessary for sustainable growth.
Linux binary compatibility remains a complex issue rooted in global symbol tables and ABI incompatibility, with AppImage and Flatpak offering convenience but not solving the underlying problems.

Introducing Bielzat: The Mind Behind ECWolf
Brody introduces Braden Obazat, known as Bielzat or Blzut3, the maintainer of ECWolf and former key contributor to ZDoom. The episode begins with a brief technical hiccup and sets the stage for a deep dive into retro game preservation and open-source development.
The Birth of ECWolf and the Wolfenstein 3D Source Port Landscape
“ECWolf was literally started because Wolfenstein 3D did not have volume controls and I wanted to independently control the sound effect volume from the music volume.”
ZDoom’s Legacy: From Modding Revolution to Community Fracture
“The only reason the split could happen is because the project is healthier than it’s ever been.”
The Art of Modding: Decorate, ZScript, and the Power of Accessibility
“One of the things that ZDoom has done really well is being very easy for people to get into as far as modding.”
Why Doom Has So Many Ports, But Wolfenstein Doesn’t
Obazat contrasts the ecosystems of Doom and Wolfenstein 3D source ports, citing the presence of assembly code in Wolfenstein as a major barrier to early development. He also discusses the game’s repetitive nature and how it limits long-term community engagement.
“I think the open-sourcing of Doom and Wolfenstein 3D code in the 1990s was a pivotal moment that enabled decades of modding, commercial games, and even careers.”
“The only reason the split could happen is because the project is healthier than it’s ever been.”
“Seeing people being enabled to create things and seeing people release games on Steam and building their careers off of things is actually very rewarding to me.”
