#    - libsndfile-1.dll beside the exe; OpenAL32.dll copied from the system

=================

Run start-windowed.bat (or: rpl4opt.exe -windowed -res 800 600 -egg TEST.EGG).
No cockpit hardware needed. If there is no sound, run oalinst.exe once.

Controls (XInput controller and/or keyboard) - EVERY input is
rebindable: edit bindings.txt beside the exe (written with the full
documented default layout on first run; delete it to restore).

  LT / RT   or NumPad 7,9  left / right pedal
  Right stick Y            throttle (holds position)
  Shift / Ctrl             throttle up / down

  F1-F12                   secondary / screen columns
  Alt+Q                    abort the mission (score banked)

The full pod cockpit comes up in a single window: three green MFDs
across the top, the 3D viewscreen centered with the orange plasma glass
at its left, and the lower MFDs flanking the portrait map. The red
buttons around each MFD and the amber buttons beside the map are the
pod's real button banks: click them with the mouse, and they light up
as the game commands their lamps.
environ.ini is self-documenting: every option ships in the file with
a comment (Steam networking, keyboard lighting, stick inversion, LAN
hosting, developer keys, and more).

Known prototype notes: pods race untextured (the player1-8 skins come
from the presets system, not shipped data), and text drawn on the plasma
glass may appear rotated.
