#    - Release\rpl4opt.exe (+ .pdb for crash debugging)
#    - game data from assets\RP411 (AUDIO, GAUGE, VIDEO, INIs, RPL4.RES,
#      TEST.EGG) — but not the arcade launch scripts or the old 4.10 exe
#    - libsndfile-1.dll beside the exe; OpenAL32.dll copied from the system
#      when installed, with oalinst.exe included as the fallback installer
#    - a desktop environ.ini (PAD;KEYBOARD controls, on-screen plasma)
#    - start-windowed.bat and a README

#  Usage:  powershell -ExecutionPolicy Bypass -File pack-dist.ps1 [-Zip]

Red Planet 4.12 - desktop prototype
===================================

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):

  Left stick / WASD        joystick
  LT / RT   or  Q / E      left / right pedal
  Right stick Y, PgUp/PgDn throttle (holds position)
  A / Space                joystick trigger
  B / R                    reverse thrust
  DPad / arrow keys        joystick hat (look)
  Start,Back / F1,F2       config buttons

The full pod cockpit comes up as separate windows: the main view, five
green MFD screens, the portrait map, and the orange plasma glass below
the main view. Drag them wherever you like; closing one just hides it.
environ.ini options: L4PADFLIP=XY inverts the stick axes, L4MFDSCALE=n
sizes the MFD/map windows (percent, default 50), L4PLASMASCALE=n sets
the plasma pixel size (default 4), L4PLASMAPOS=x,y places the plasma.

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.
