Configuration

What happens

Use when

Visible

VICE_VISIBLE=true

VICE opens a normal desktop window. Warp defaults to off.

You are developing locally and want to watch or interact with the emulator.

Minimized

VICE_VISIBLE=true, VICE_ARGS="-minimized"

VICE still runs as a normal desktop app, but its window starts iconified. Binary Monitor operations, screen reads, frame capture, and keyboard input continue to work.

You are using an agent locally and do not want the emulator stealing focus, but still want the option to restore the window.

Headless/Xvfb

VICE_VISIBLE=false

C64 Bridge launches VICE without a user-facing desktop window, using Xvfb unless disabled. Warp defaults to on.

CI, unattended tests, servers, or any session where no one needs to inspect the emulator window.
