The pod's controls reach the game through the RIO serial board; on a
desktop that hardware is a keyboard shim of hardcoded GetAsyncKeyState
reads. New binding engine (game/reconstructed/btinput.cpp) maps PC keys
and an XInput pad onto the authentic channels through a user-editable
file (content/CONTROLS.MAP, community-suggested grammar, corrected):
key/pad -> button <addr> real buttonGroup emissions, mirroring the
RIO convention exactly (press a+1 w/ mode
mask saved, release -a-1 w/ saved mask;
L4CTRL.cpp:2470-2520) -- aux/preset banks,
hotbox, panic, reverse thrust all reachable
key/pad -> axis Throttle rate (lever), pedals/JoystickX
deflect (turn/twist) into the existing
virtual-controls integrators (feel, gait
detent, spring-centering all unchanged)
keypad pilot|external <n> keyboardGroup key values ('0'-'F')
pckey <char> any authentic 1995 typed hotkey
action <name> port dev controls (view, all-stop, ...)
Keys claimed by a binding are SUPPRESSED from the legacy WM_CHAR/KEYUP
feed -- ends the historic double-dispatch ('w' drove AND selected pilot
0; F5's key-up value 0x74 aliased to the 't' hotkey; letter key-ups fed
the developer fake-event dispatcher). Unbound keys keep their authentic
meaning. The dual-use 'V' is split: V = view toggle, B = look behind.
Default profile = WASD classic (compiled-in twin; delete the file to
restore). CONTROLS_NUMPAD.MAP ships the corrected community layout
(keypads are NOT buttons 0x50-0x6F -- that space doesn't exist; no
clickable cockpit exists so everything needs a binding; keyboard fire
buttons added; 0x36/0x37 are hotbox not 'config'; missiles moved off
Ctrl). XInput loads dynamically (1_4 -> 9_1_0), disconnected-pad
probing rate-limited; pad sticks write the axes as absolute positions
(the spring is physical), triggers/buttons per the file.
Verified live: bindings load (43), W and NumPad8 drive (speedDemand 0 ->
61.5), X all-stop (spd -> 0), aux-bank emission (D1 -> [input] 0x2f
PRESS/release under the numpad profile), suppression both directions
(posted 'r' reaches [keych], posted 'w' swallowed), full-keyspace
WM_CHAR+WM_KEYUP fuzz x3 survived with sim advancing, XInput graceful
with no pad, 2-node relay session un-regressed (full ladder + UDP).
Pad-in-hand testing still needs a physical controller.

// the analog values the RIO would have produced
|
|
// buttons -> real buttonGroup[addr] ForceUpdates (aux banks, hotbox,

// panic, throttle-head...) so the AUTHENTIC handlers fire;
