Advanced tab

CUSTOM THEME EDITOR

Available when App Theme is set to CUSTOM. Paste HSL variable overrides in CSS format to define your own colour palette. See the Theming guide for the full variable reference.

• Wrap in .custom { } — surrounds your CSS block with the required .custom {} wrapper.
• Reset to defaults — populates the editor with the default dark theme values as a starting point.

Paths tab

Configure directories for Source Ports, Wads, Mods, Saves and Screenshots.

Source Ports

As of vE1M0.3.1, the Source Ports section (under CORE INFRASTRUCTURE) lets you manage multiple source port executables.

• Click + Add Port to open a file picker and select an executable.
• Use the inline form to set name, version, executable path, and family.
• Click the radio dot on the left to set a port as the default.
• Use the eye icon to hide a port from game instance selectors without deleting it.
• Use the pencil (edit) and trash (delete) icons to manage ports.

See the Manage source ports page for full details.

Upgrading from an earlier version? Your old single source port path is automatically migrated on first launch.

Other Paths

Default values:

Use	Default	Notes
Wads	~/.config/uac/wads	Directory for base game WAD files.
Mods	~/.config/uac/mods	Each game instance gets a .json file here. Mod files are copied to a files subdirectory.
Saves	~/.config/uac/saves	Save data, subdirectories created per game instance (e.g. dragon-sector-remake).
Screenshots	~/Pictures/UAC Launch Control/screenshots	Screenshot output, uses your source port’s default naming.

All paths can be typed manually or set via the folder icon (📂) file picker.

Note on ~

The tilde (~) expands to your home directory:

• Windows: C:\Users\YOUR-NAME
• macOS: /Users/YOUR-NAME
• Linux: /home/YOUR-USER

Wad Config tab

Configure settings for each detected base game WAD — shown name, icon, launch arguments, and additional parameters.

The application auto-detects these WADs: doom.wad, doomu.wad, doom2.wad, doomii.wad, tnt.wad, plutonia.wad, freedoom1.wad, freedoom2.wad, heretic.wad, hexen.wad, hexdd.wad, strife.wad — each gets a default name and icon.

• Icon — click the icon preview to set a custom image.
• Launch Arguments — e.g. -iwad or other flags passed to the source port.
• Additional Parameters — e.g. -nomonsters -warp 01.
• Hide from Interface — excludes the WAD from the sidebar and base game selectors (useful for auxiliary files like voices.wad).
• File Source — the actual file path on disk (read-only).

Note: The per-WAD engine/executable setting was removed in vE1M0.3.1. Source ports are now managed globally via the Paths tab — you assign a source port per game instance, not per WAD. See Manage source ports.
