The front end and the docked screens run at 640 x 400

What to know

2026-10-24, measured in the running original (docs/ground-truth.md).

With ResolutionX 640 and ResolutionY 480, the window was 640 x 400 in the front end, the pause console and the docked computer, and 640 x 480 in flight (measured: the window's geometry, and the mode at 0x599efc/0x599f00 read from the recorder's memory dumps).

Why: the console code sets 640 x 400 at 8 bits itself, at 0x4435ce (FUN_0049b3b8(0x280, 0x190, 0, 0x200)); flight sets the configured mode through the calls at 0x43b3b7-0x43b626 (observed). WM_GETMINMAXINFO (case 0x24 of the window procedure) caps the window at the current mode (0x599a28/0x599a2c), so it cannot be resized from outside.

What it means for recorded frames: the docked computer is drawn into 400 lines, and its cockpit frame is cut at the bottom of the window. Whether the original under Windows 95 shows the same cut, or draws the docked screens into a 480-line mode, is unknown. Compare with a frame from a real Windows machine before treating the cut as part of the reference.
