Break the desktop glass cockpit's secondary displays out of the single
combined pad panel + D3D gauge strip into ONE window per pod display, each
carrying that display's surface with its RIO button bank, arranged
pod-faithfully around the main view. New TU engine/MUNGA_L4/L4GLASSWIN.*
(BT_GLASS-only), selected by the -platform glass preset via the new runtime
gate BT_GLASS_PANELS (=0 falls back to the legacy single panel + dock).
- Surfaces are CPU-expanded from the shared gauge buffer
(SVGA16::ExpandPlaneToBGRA, no D3D) and StretchDIBits'd in -- the D3D
dev-composite path (dock / window / overlay) stands down while active.
- Buttons sit UNDER the imagery: big hidden click targets that reach into
the display, with only a small protruding edge showing as a lamp light.
Red MFD banks tile the top/bottom; radar rails run the sides + a bottom
row; a Flight Controls window hosts the no-display banks.
- Windows: Heat / Engineering / Comm / Left Weapons / Right Weapons / radar
+ Flight Controls; edge-to-edge (no in-client margin/title; OS caption
labels each).
- Fix blank surfaces: application/ghWnd are duplicate-defined and bind
non-deterministically under /FORCE, so the fresh L4GLASSWIN TU read NULL.
Reach the renderer/window via BTResolveGaugeRenderer/BTResolveMainWindow
defined in btl4main.cpp off the real btl4App/hWnd pointers. New gotcha:
reconstruction-gotchas.md S6 duplicate-GLOBAL corollary.

33 master commits in (relay TCP/UDP + PySide6 operator console, CONTROLS.MAP
+XInput binding engine, camera seats, torso pitch aim, sign fixes, the 1995
manual, version stamping, 18-mech certification). Conflicts: .gitignore +
CLAUDE.md router rows (combined).
SEMANTIC RECONCILIATION (the one real overlap): masters btinput binding
engine (ungated, CONTROLS.MAP) and the glass PadRIO (gated, bindings.txt)
would both read the keyboard/pad in a glass+PAD session. btinput now joins
the stand-down convention: BTInputPoll yields (and BTInputSuppressKey claims
NOTHING, so authentic hotkeys flow) when an operational cockpit device owns
the input path -- BTRIODevicePresent, BT_KEY_BRIDGE force-override honored,
forced harness exempt. One input system per mode: btinput on pod/dev
desktops, PadRIO on glass. The mechmppr/mech4 bridge merges composed clean
(masters negate-once sign fix inside our device-gated bridge). The D1 relay
keeps its own raw sockets by design (an alternative LAN wire; Steam and
relay are separate modes).
Verified post-merge: all 3 configs build; glass boots with [input] binding
engine standing down + PadRIO owning input (30 ticks); pod forced-walk
speedDemand=61.501 with btinput ACTIVE; 2-node loopback MP full 31/31
mission, 76/76 ticks.

4.10 = the 1995 arcade release; 4.11 = the win32 reconstruction; the
build number is the git commit count -- monotonic, zero-maintenance,
and every exe pins to exact source via the short hash ('+' = built
from an uncommitted tree). tools/btversion.cmake regenerates
build/btversion.h on every build (write-if-changed, no rebuild churn);
the stamp shows in the boot banner (btl4.log head, replacing the stale
'v4.10' line) and the window title (incl. the MP node tag).
Verified: build stamps 4.11.311 (980c9cd+), banner + title correct on
a live boot.

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.

NEW gated (BT_STEAM) game/glass/btl4lobby: an ISteamMatchmaking room replacing
the arcade Site-Management screen -- host creates (lobby data btl4=1), members
join by filter, pilots publish name/mech/color, the host ENTER mints the
roster and signals GO.
THE FAKEIP LESSON (live-verified, prior-art assumption DISPROVEN): a fresh
process gets a DIFFERENT FakeIP, so menu-time fake addresses go stale by
mission time -- the first cycle timed out connecting to its own stale address.
Redesign: roster addresses are opaque ipv4-shaped TOKENS (169.254.77.N with
ports 1501/1502) minted by the host at GO, mapped to Steam IDENTITIES;
connections ride ConnectP2P(identity, channel) with console=0/game=1 virtual
ports; the map reaches mission processes via env (BT_FE_MYFAKE +
BT_FE_STEAMMAP); the GetMyAddress seam feeds the pod its own token for roster
self-match; CheckSocket reports peers by token. L4STEAMNET reworked (no
FakeIP allocation at all); the marshal gained the Steam-wire branch.
Verified single-machine (ON/ON, live Steam): menu -> HOST STEAM LOBBY ->
room -> GO -> token map minted -> egg roster carries the token -> mission
process up with 1 roster token incl. self -> pod self-matches -> stock
console ladder -> mission RUNS (46 ticks). Remaining: the live 2-account
cross-machine session (docs/STEAM_TEST.md).

NEW gated (BT_STEAM) TU L4STEAMNET: ISteamNetworkingSockets with FakeIP --
pseudo-SOCKET handles (0x5EA0xxxx) behind the L4NET BTNet* seam; the engine
TCP byte stream rides reliable-NoNagle Steam messages re-assembled into
per-connection rings (nonblocking recv semantics preserved: empty ->
WSAEWOULDBLOCK, peer-closed -> 0); two FakeIP ports mirror the arcade
console/game channel convention; listen sockets + accept queues via the
global status-changed callback; graceful degrade to Winsock at every step.
Seam completions in L4NET.CPP: CheckSocket reports a pseudo-socket peer as
its FAKE ipv4:port (the lobby egg roster matches unchanged); OpenConnection
TCP_OPEN delegates FakeIP targets to BTSteamNet_Connect. WinMain installs
on BT_STEAM_NET=1 (lobby launch path / by hand). CMake: gated SDK include/
lib/dll-copy. Both pumps (SteamAPI_RunCallbacks + sockets RunCallbacks)
drive it -- the FakeIP result rides the GENERAL dispatch (first attempt with
only the sockets pump timed out).
Verified live (ON/ON build, Steam client running): SteamAPI_Init OK,
steam_appid.txt(480) auto-written, FakeIP allocated
(169.254.36.58, console 54464 / game 54465); without BT_STEAM_NET or
without Steam the game stays pure Winsock.

NEW gated dir game/glass/: btl4fe (green-on-black GDI catalog menu -- map/
time/weather/length/mech/color/pilot/mode/port/peers; egg writer emitting the
FULL console egg shape, golden-tested vs MP.EGG: identical section sequence
at identical line offsets, the 4 static ordinal pages verbatim, GDI-rendered
128x32/64x16 pilot-name plasma bitmaps in MP.EGG framing) and btl4console
(the marshal: a worker-thread console CLIENT speaking the btconsole.py wire
protocol verbatim -- 1040-byte chunked egg, 20s settle, RunMission x2,
STAY CONNECTED, own the clock, StopMission at expiry; logs marshal.log).
The engine sees a real connected console and runs the 100% stock ladder --
NO engine hooks (less invasive than planned: the L4APP.H setters proved
unnecessary; launches go through real argv on relaunch).
WinMain (one gated block): zero-mission-arg glass launch -> menu -> relaunch
self with the mission argv (per-mission process relaunch; BT_FE_* env arms
the marshal); post-RunMissions BT_FE_LOOP tail returns to the menu. Menu
relaunches CLEAR the BT_FE_* handoff (found live: the inherited env re-armed
a marshal instead of showing the menu).
Verified end-to-end (synthetic menu drive): menu -> frontend.egg -> relaunch
-> marshal feeds self over loopback -> stock console ladder -> mission RUNS
(58+ ticks) -> 60s clock -> StopMission -> clean menu return, no env leak.

NEW gated TUs: L4PADPANEL (GDI top-level window, all-W APIs: the pod button
banks -- upper/lower aux, 12 secondary, specials/hat/handle, 63 buttons --
clickable via PadRIO::SetScreenButton with lamp-lit faces from GetLampState,
10 Hz repaint; created by the PadRIO ctor on BT_PAD_PANEL=1) and L4PLASMAWIN
(PlasmaWindow : Video8BitBuffered -- the gauge renderer draws the 128x32
plasma into its pixelBuffer through the SAME code path as the serial device;
Update() blits orange-on-black at L4PLASMASCALE, default x4). Gated seams:
L4GREND.cpp L4PLASMA=SCREEN branch; btl4main.cpp -platform glass preset
(PAD,KEYBOARD + BT_DEV_GAUGES + SCREEN plasma + panel; env always overrides;
non-glass builds log+fall back to DEV); run.cmd glass token. MFD surfaces
need NO new code: the existing dock-bottom / BT_DEV_GAUGES_WINDOW=1 /
BT_DEV_GAUGES_DOCK=1 modes are the display story.
Verified live: -platform glass boots GLASS profile, panel + plasma windows
up, pad detected, dev gauges awake, mission loop clean.

L4RIO.h splits the abstract cockpit-control surface (RIOBase: enums, the five
analog Scalars, GetNextEvent/SetLamp, no-op serial ops, NEW IsOperational) out
of the serial RIO (RIO : PCSerialPacket, RIOBase -- byte-for-byte behavior kept,
ctor assigns as before); LBE4ControlsManager holds a RIOBase* and gains the
gated L4CONTROLS=PAD factory arm (BT_GLASS; OFF build logs+ignores the token).
NEW gated TUs: L4PADRIO (XInput+keyboard synthesize the surface; 3s hot-plug
re-probe; focus-guarded keys; per-poll AnalogEvent heartbeat; lampState[] +
static SetScreenButton/GetLampState for the panel) and L4PADBINDINGS
(content\bindings.txt profile, self-documenting default written on first run;
deflect/slew/set axis model; addresses validated against ButtonCount).
Verified live (glass build, L4CONTROLS=PAD): bindings written+parsed 44/10/5,
XInput pad detected, 121 streamed mappings install via stock PrimaryRIO path,
2157 frames clean. Pod build (gates OFF) compiles the split with zero
behavioral delta.

New L4AUDEFX bridge (OpenAL Soft ALC_EXT_EFX): one EAXReverb aux slot at the
authentic AUDIO.INI global_reverb_scale (0.3) + a scratch AL_FILTER_LOWPASS
(params copied at attach).
F9 filters (was: computed then thrown away -- everything full-bright at all
distances): Dynamic3D ExecuteModel drives GAINHF from highFreqCutoffScale x
brightnessScale x maxMIDIFilterCutoff, UNGATED (decomp part_008.c:7496,
7589-7604 -- every moving 3D sound dulls with distance per the AUDIO.INI
knee-60/exp-2.0 model); Static3D from brightness x max (:7831-7884); Direct
inside its existing gated NRPN-rate block. AWE 100-8000 Hz curve -> EFX
5 kHz-reference gainhf via a 2-pole approximation [T3 curve, endpoints exact].
F11 reverb (was: bone-dry everywhere): 3D patch sources attach an aux send at
Start, exactly where the original sent CC91 = global_reverb_scale
(part_008.c:7278-7394); Direct cockpit sources keep CC91=0 -- dry. The
wet-exterior vs dry-cockpit contrast is back.
F12 placement (was: every cockpit sound dead-center): DirectPatchSource
Start places sources by the authored 6-value position enum (front/rear card
+ pan CC10, decomp @00463848/@004638a8) as listener-relative directions,
composed with the zone L/C/R pan. New PatchResource GetBankID/GetPatchID
pass-throughs (the LOD accessor is protected).
Regression (35s drive+fire): EFX READY, stable, deliveries unregressed, no AL
errors.

Root cause of "no sound, ever": the two audio backend DLLs shipped in the repo
are fakes. libsndfile-1.dll exports 15 funcs BY ORDINAL ONLY (no names) and
sf_open() always returns NULL; OpenAL32.dll (72KB) imports only KERNEL32 -- no
dsound/wasapi/winmm -- so it is a pure no-op that returns fake handles
(ctx=0x00000001, alGenSources->0) and never touches the hardware. The whole
render->device->buffer->source->play chain ran clean and silent.
Fixes:
- OpenAL32.dll: replace the stub with the real OpenAL Soft 1.25.2 Win32 build
(imports AVRT/ole32/WINMM, real WASAPI backend). The exe imports the 25 AL
funcs by NAME so it is a drop-in; alGenSources now yields a live source and
alSourcePlay reaches AL_PLAYING.
- libsndfile: DROPPED entirely. It is replaced by LoadWavPCM() in L4AUDRES --
a tiny RIFF/WAVE fmt+data reader that loads our soundbank WAVs (16-bit PCM)
straight into the AL buffer. Removed the .lib/.dll from the link + copy and
git-rm'd the stub. (This also kills the "ordinal 50 could not be located in
libsndfile-1.dll" load-failure popup: adding an sf_strerror import bound to
an ordinal the 2..16-only stub could not satisfy.)
- Soundbank: 241 samples cracked from AUDIO1/2.RES (SF2 v1.0) by
tools/sf2extract.py into content/AUDIO/*.wav + the allPresets[2][128] table
(audiopresets.cpp), replacing the zero-init btstubs stub. All 241 now load
(alErr=0). BT_AUDIO_TEST plays buffer0 as proof-of-life; BT_AUDIO_LOG traces
the chain.
Remaining: in-game triggering (AudioEntities on fire/step/engine/explosion)
so PlayNote fires during play -- next audio wave.

records; also the 2007 call-counter clock stub + two crash fixes
User-reported: peer mechs turn/move choppy ("missing frames"). Measured per-frame
(BT_REPL_HDG): 13% of frames the replicant's heading STALLED, 11% it JUMPED 2-6x.
THREE layered defects found:
1) THE CLOCK STUB (engine substrate): TIMESTUB.cpp's GetRTC/GetHiRes were 2007
`return time++` call-counters -- the "clock" advanced per CALL, not per ms --
and TIMESTUB won the /FORCE duplicate-symbol race over the REAL QPC clock in
L4TIME.cpp (LNK4006). Every Now()-domain consumer (dead-reckon above all) ran
on call-count pseudo-time. Removed TIMESTUB from the build; L4TIME covers every
symbol. [The real clock alone did NOT cure the chop -- but it was objectively
broken and un-gated the two latent bugs below.]
2) TWO CRASH FIXES the real clock exposed:
- legAnimationState@0x3b0 never ctor-initialized (the task-#56 0xCDCDCDCD
family): the type-3 writer re-dispatches SetBodyAnimation(legAnimationState)
on the WRITER; a record emitted before the leg SM's first tick passed raw
0xCDCDCDCD as a clip index -> AV (cdb-pinned, mech2.cpp:233). Init 0.
- Replicants were SERIALIZING update records: the tail WriteSimulationUpdate ran
for every instance, and the port's replicant leg-SM accommodation (task #50)
calls ForceUpdate -> replicants emitted derived/uninitialized state into the
stream. Master-gated; replicant marks discarded (master-authoritative).
3) THE CHOP ITSELF: the master's resync send-gate compares localOrigin vs
projectedOrigin -- the PEER-ESTIMATE mirror -- but the port master never
maintained projectedOrigin (the bring-up drive replaced Mover::Perform; the
engine only updates the projection inside replicant-only DeadReckon). Stale
mirror -> |local-projected| > deadband EVERY frame -> a type-4 re-base record
EVERY frame -> the replicant hard-copied the master's deadband-quantized
heading each frame (the engine lerp never engaged; nextUpdate always behind
till) -> stall/snap beat = the chop. FIX: advance the mirror each frame by the
last-SENT angular velocity (what the peer is extrapolating) and re-base it in
the type-4 writer. Records now flow only on TRUE drift (~1 per 5 frames in a
steady spin), the replicant extrapolates smoothly between them, and the lerp
horizon finally engages. Measured: STALLS 13%->1%, JUMPS 11%->1% (residue: tiny
sub-degree backward corrections on record arrival -- inherent dead-reckon
overshoot the lerp absorbs).
Diag probes: BT_REPL_HDG (per-frame replicant heading + dead-reckon internals),
BT_REPL_TRN (replicant turn/leg state). scratchpad/clockcrash_bp.txt (cdb).

Clean, self-contained extraction of the BattleTech-specific work from the
reverse-engineering workspace -- engine + game + content + build, with nothing
from Red Planet or the raw archive dumps. Builds green (Win32) and runs the
single-player drive->animate->target->fire->damage->destroy loop out of the box.
Layout:
engine/ MUNGA + MUNGA_L4 shared 2007 engine, carrying our BT render/loader
work (bgfload/L4D3D/L4VIDEO: BSL bit-slice decode, LOD/ground/shadow
models) + image codec; the minimal rp/ headers the audio HAL needs
game/ reconstructed BT logic + surviving-original BT source + fwd shims
+ WinMain launcher
content/ full runtime tree (BTL4.RES, VIDEO/, GAUGE/, AUDIO/, eggs, BTDPL.INI)
docs/ format specs + reconstruction ledgers
reference/ raw Ghidra pseudocode (recon source-of-truth) + decomp exporter
tools/ MP console emulator + map/resource scanners
One top-level CMake builds munga_engine lib + bt410_l4 game lib + btl4.exe.
All paths relativized (186 fwd shims + ~437 CMake abs paths -> repo-relative);
DXSDK is the one external, overridable via -DDXSDK. Verified: builds to a
byte-identical 2.27MB exe and runs combat (TARGET DESTROYED, 0 crashes) against
the bundled content.
