Presets — The Core Feature

What Are Presets?

A preset is a portable .preset file that captures your entire DOOM launch configuration — engine, IWAD, PWAD list, custom parameters — in a single shareable JSON file. Share your perfect setup with the community or restore it later with one click.

How It Works

1 Set up your engine, pick an IWAD, add your PWADs and any custom launch parameters.

2 Save the configuration as a .preset file — it stores everything in a clean JSON format.

3 Share your preset with others or load it later to instantly restore the same setup.

4 Browse the community preset library on zereb.net — hundreds of configurations for different IWADs and source ports.

5 Apply any preset from the library with a single click. The app configures itself automatically.
