Full-screen (with Glide): MXL launcher → Settings → Uncheck "play in windowed mode" → open "⚙️ Glide Settings" → 'Settings' tab → Turn off 'window-mode' → Set 'static size' to 'no' → Check the 'desktopresolution' box → Uncheck the 'keep aspect ratio' box → Quit and close the Launcher → re-open it and then launch the game.
Right now I do not reacll of an easy way of achieving fullscreen with Direct3D and DirectDraw (2D). Someone knowledgeable about this could chime in.
