// FS2's boot sequence prompts the user at runtime: first for display
// mode (color vs B&W via "WHAT DISPLAY ARE YOU USING? A or B"), then
// for game mode (demo vs regular flight). The scenery-disk versions
// add a city/region pick step. The port consolidates all of those
// pre-sim choices into one config menu plus the in-flight `F7` edit
// toggle.
