WAVE 4 (standalone readouts) -- Sensor(0xBC3)/Searchlight(0xBD8)/
ThermalSight(0xBDE)/AmmoBin(0xBCB) un-stubbed via Create<Class>Subsystem
bridges + Torso-style de-shim (drop cross-family shadow fields, redirect
accessors to the real inherited base, static_assert layout locks).
- FIX: Searchlight/ThermalSight ctors gated their Performance on the shadow
segmentFlags(=0) so it NEVER installed; switched to owner->simulationFlags.
- AmmoBin: retype ammoAlarm HeatAlarm->WatcherGaugeAlarm(0x54) + drop the
statusState@0x40 shadow -> exact 0x22C layout.
- Guard HeatWatcher::WatchSimulation against the unresolved watchedLink
(null-deref exposed once these sims run; faithful fix = resolve the link).
- Heat-leaf branch (Sensor) is not byte-exact -> overflow-lock only.
WAVE 6 (Myomers 0xBC6, mover-coupled) -- structural un-stub, gated
BT_MYOMERS (default on; =0 -> Actuator stub). Wired INERT: MyomersSimulation
early-returns (advanced-damage gate stubbed) + no-op mover feed, so the live
JointedMover is untouched and the gait cannot regress. De-shim drops the
owner*/segmentFlags shims to fit the exact-0x358 alloc. Authentic mover/heat
coupling deferred (needs messmgr 0xBD3 + reconciling the mover feed with the
gait cutover).
Verified: BLH tick 20->27, Mad Cat 24, combat DESTROYED un-regressed,
locomotion un-regressed, 0 crashes, 0 heap detections under BT_HEAPCHECK.

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.
