These images were drawn by the original GO executable using its real artwork and fonts. The host harness supplies files, VGA memory and raw joystick samples; the DOS mouse cursor is hidden. The flat orange area is the harness background.

Original calibration instructions and device selector.

The calibration UI stores sixteen signed 32-bit values in JOY1.CAL or JOY2.CAL. Its list depends on the configured device. The authored Flightstick slider label and instructions exist but are not enabled by the original selectable-device table. Cancelling after sampling can leave the live calibration partly modified: the original reset clears its device pointer before its rollback routine runs. It does not save those changes.
