Audio Phase 1 (AUDIO_FIDELITY F3/F4/F10/F15/F18/F20 + KB): the quick wins
F3 distance: alDistanceModel(AL_NONE); restored the commented authored distance multiply in Dynamic3D::CalculateSourceVolumeScale, added the same override to Static3D, dropped the (now inert) AL_MAX_DISTANCE writes. Far battle audio follows the authored knee/rolloff curve again, and the volume cull / voice steal / ducking chains are distance-aware. F4 volume law: AL_GAIN = volume_scale^2 at all 3 per-frame sites (Direct/ Dyn3D/Static3D) -- the GM CC7 squared curve; linear was ~+6 dB at mids. F10 doppler: alDopplerFactor(0) (AL's model ran wrong constants + sign- inverted velocity: approaching sources pitched DOWN); the AUTHORED dopplerCents (AUDIO.INI range/speed-of-sound model, decomp-proven consumer part_008.c:7466) now adds into the Dynamic3D pitch chain. F15 ConfigureActivePress: published at the MechSubsystem BASE (binary id 2, descriptor @0x50de5c -> +0x110); renamed the misnamed vitalSubsystemIndex member (the weapon ConfigureMappables handler already drives it 0/-1). Removed the invented Sensor/Myomers duplicates and RESTORED their byte- exact layouts (0x328/0x358 allocs + asserts). MechWeapon's pinned-id pad absorbed the +1 chain shift -- which matches the binary's own numbering. F18 cook-off warning: AmmoBin FireCountdownStarted -> the existing cookOffArmed @0x18C (binary table @0x512600); the countdown klaxon can fire. F20 zoom blip: L4MechControlsMapper publishes TargetRangeExponent -> the live @0x1a4 zoom member (own table chained to MechControlsMapper). KB: replaced the bogus divisionParameters+0x10 rate read with SystemClock::GetTicksPerSecond() (FUN_0044e19c is GetFrameRate -- original audio frames were CLOCK TICKS). Regression (35s drive+fire): stable; ConfigureActivePress binds real on all 9 subsystems (idle -1, zero pad redirects); FireCountdownStarted + TargetRangeExponent bind live members; attrnull 53 -> 41; chirp still dead; footfalls still fire (gain now correctly squared).

Fix throttle-detent Abs() macro bug + KB analog-throttle + slide diagnostics (task #50)
Uncommitted work from the speed-model + peer-motion investigation: - btl4mppr.cpp: the L4MechControlsMapper full-throttle detent used the unparenthesized Abs() macro (STYLE.H:118) on an expression -- Abs(throttlePos - 1.0f) mis-expands to -(throttlePos + 1.0f), always <= 0.05, so the detent snapped throttle to full EVERY frame. Diff into a temp first (same class as the |

Cockpit: the CONFIG-MODE weapon-regrouping session + the live-play fire fixes (tasks #6+#11)
TASK #6 -- the pod's in-cockpit weapon regrouping, fully reconstructed and live-verified (hold-configure -> tap fire button -> toggle membership -> release-commit): - MechWeapon handlers id 9 ConfigureMappables @004b9550 / id 10 ChooseButton @004b95b8 (binary table @0x511860; the old "Myomers fns" mislabel swept) + the GetMessageHandlers() accessor chain through Emitter/ProjectileWeapon/ MissileLauncher/GAUSS/PPC (empty per-class sets swallowed dispatch). - Mapper vtable truth: +0x38 EnterConfiguration / +0x3C ExitConfiguration / +0x40,+0x44 AddOrErase evt/dir. No "secondary vtable @0050f498", no "CreateTemporaryEventMappings" virtual (RP-name drift; swept incl CLASSMAP). L4 Enter/Exit rebuilt complete: StartMappableButtonsConfigure (the NonMapping 0x10000 <-> Mapping 0x8000 mode flip + the gauge's active-weapon latch) + the held-button re-arm + the 4 fire-button temp maps; only the RIO mapper implements the toggle (Thrustmaster no-ops = can't regroup). - MechSubsystem +0xE8/+0xEC corrected to controlDestination/controlMessageID (ex hostEntity/subsystemId2 mislabel); MechWeapon ctor defaults the destination to &fireImpulse (@004b99a8). - ConfigMapGauge state loop reconstructed (PE-recovered DAT_00518eb4 table; buttonGroup GetMapState sampler -- the "needs ModeManager" guard rationale was wrong). Finding [T1]: the shipped binary NEVER enables this gauge (no SetColor caller) -- authentically dormant; BT_CONFIGMAP=1 is the dev enable. - Dev harness: HOLD 'G' opens the session (BT_CONFIG_SLOT picks the weapon); BT_CONFIG_TEST scripts a headless verify. @004afbc4 corrected to its real Fail-trap body (the guessed AddOrErase(NULL) body would corrupt groups). - Bonus [T1]: the binary MechWeapon ATTRIBUTE table has ELEVEN entries (PercentDone..WeaponState) -- "TriggerState is the only one" was wrong. TASK #11 -- the user-reported live-play regressions (both real bugs): - PHANTOM FIRE: the mech4 bring-up shot block painted an explosion at the victim on its OWN 0.3s cadence whenever fire was held -- desynced once the authentic recharges landed. Retired (the real impact visual flows from each discharge via the messmgr SubmitExplosion). - WEAPON BRICKING (the "cuts out" bug): the Loading->Loaded snap window (+-0.01 around seekV) assumes the pod's LOCKED 60 fps; one port dt-spike jumps it, the byte-verified >1.0 clamp (_DAT_004ba830=0) zeroes readiness, and the weapon sticks in Loading at level ~10000 forever (observed live). Fixed with pod-frame (1/60s) sub-stepping of the binary's own Loading tick -- also fixes the I^2R integral over-heating generators on big steps. NEW GOTCHA CLASS recorded: reconstruction-gotchas #12 (frame-pacing trap). - Duty-cycle measured (max-rate autofire): generators equilibrate in the degradation band (recharge stretch ~3.5-4.4x), the FailureHeat breaker never trips solo, PPCs sustain ~11.8-damage full-charge fire. The slow kill pacing and recharge gaps are the AUTHENTIC heat economy; the pilot's counters (this regrouping UI, generator reassignment, coolant valves) are the reconstruction queue.

Initial commit: bt411 -- standalone Windows BattleTech (Tesla 4.10 port)
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.
