What it does

On startup the mod sets up the game window as borderless 4:3 automatically, so no manual window configuration is needed. Only the client needs it, and the server does not. Gyo requires Fabric API, and Mod Menu is optional for its settings screen. Builds cover 1.21 – 1.21.10 and the latest file is 0.7.0+1.21.10 for 1.21.10, released 2025-11-17. Gyo is open source and released under the GNU Lesser General Public License v3.0 only.

Key features

  1. Borderless 4:3 window

    The game window runs borderless at a 4:3 aspect ratio.

  2. Automatic window setup

    The window is configured on launch, with no manual changes needed each time the game starts.

  3. Title screen integration

    The mod takes effect from the title screen onward, so the window is ready before a world loads.
