Fire VISUALS wave: the authored firesmoke sheet, vertex-alpha effect cards, the case-4 wreck dressing
The "fireballs like the demo vids" arc, decomp/content-grounded end to end,
plus the live-play UX batch verified over the same sessions:
FIRESMOKE SHEET (the PFX fireball fix): every firesmokeN_scr_tex in BTFX.VMF
maps the SAME 64x64 tileable noise image bintA (variants differ only in SCROLL
rate) and firesmoke1_mtl colours it through the "fiery" ramp (0.3,0.1,0.1)->
(0.9,0.7,0.3). The particle layer now bakes ramp(lum(bintA)) as its sprite
colour (noise detail in alpha) and SCROLLS it at firesmoke1's authored rate
via a texture-transform; the port's radial soft-edge mask moved to a second
CLAMPed stage so the WRAPPED scroll rolls flame through the sprite without
scrolling the edge away. Old grit x radial bake kept as the no-BINTA fallback.
Impact hits, damage-band smoke and death booms all ride this layer.
AUTHORED TEXTURE SCROLL in the model path: the BMF TEXTURE records carry
SPECIAL " SCROLL u0 v0 du dv" (tag 0x2037); the draw path always supported
per-op scrolling (SetTextureScrolling) but the BGF loader never parsed it, so
every scrolling material rendered frozen. Wired TexRef -> MatInfo -> batch ->
L4TEXOP.doScroll: the flame cards (flamebig/fire5) now roll fire noise.
VERTEX-ALPHA EFFECT CARDS (the "twisted drill bit of fire" fix): FLAMEBIG's
verts carry authored float RGBA -- white-hot base (1.0,0.99,0.97) -> dark-red
tip fading to alpha -0.2 (the DPL clamp convention). The loader kept a flat
batch colour and drew it OPAQUE = a solid orange spike. Corpus sweep: exactly
14 shipped BGFs carry vertex alpha, ALL effect cards (flames, MUZFLASH,
EXDISK_A/B/C, TMST_A/B/C, beam models, DECLOUDS). Such batches now keep the
authored per-vertex gradient and route to the alpha-blend pass, unlit,
colour = texture x gradient, alpha = the vertex fade; sky objects excluded
(drawAsSky + alphaTest passes NEITHER pass filter -- DECLOUDS stays in the
sky pass). MUZFLASH/EXDISK render correctly for free when the muzzle-model
work lands.
WRECK DRESSING (the 1996 ExplosionScripts case-4 transcription): pieces spawn
HIDDEN and reveal 0.25s after the boom (the InstanceSwitch delay, behind the
dnboom flash); flamebig hangs over the pile, Y-BILLBOARDED at the camera
(SetOffsetYaw + a camera-pos getter -- the dpl_SetDCSReorientAxes analog);
the MakeDCSFall settle arms at the reveal with the two authored rates (hulk/
debris -0.025 t^2, fires -0.01 t^2 -- the flames ride above the sinking pile
and die with it at burial). EMPTY-PLACEHOLDER hulk guard: THRDBR.BGF is a
153-byte zero-geometry stub that "loads fine" -- vertex-count check now routes
it to the gendbr fallback (a Thor wreck was invisible). Hulk content census
recorded: AVADBR==MADDBR==VULDBR geometry (palette-only prefix diffs),
RAPDBR==SNDDBR==STIDBR byte-identical -- wreck variety is materials + the
dressing, not unique piles.
LIVE-PLAY BATCH: muzzle resolve uses the named segmentIndex (raw +0xdc read
was layout garbage); forward launch frame (authored MuzzleVelocity +Z vs the
mech's -Z facing); dock-bottom single window (gauge strip appended below the
world viewport, 1100x600 default, BT_DEV_GAUGES_WINDOW=1 restores the separate
window); portrait sec surface unrotated CW; ammo counters live via typed
bridges (BTAmmoBinCountPtr/BTAmmoBinFeeding/BTWeaponAmmoBin -- raw bin+0x180
and a hand-rolled link walk were garbage); fourth fire key ('4' = Pinky);
panel/arc probes de-aliased (%61 prime).
KB: rendering.md (vertex-alpha card family + scroll), combat-damage.md (hulk
census + THRDBR stub), gauges-hud.md (ammo bridges).

MP live-play wave: collision economy, missiles, radar transform, panel polarity, comm ticker
The interactive 2-node playtest wave -- every fix decomp-grounded and live-verified: COLLISION ECONOMY (the ram one-shot): StaticBounce mutates worldLinearVelocity per contact and ProcessCollisionList walks EVERY touched solid per frame; with 2007 terrain-as-solids the reflections compounded x4-x40 within one frame and a walking bump one-shot a pristine mech for 112,375 pts (62-pt authentic economy). Fix: frameEntryWorldVelocity restore per contact (damage always priced at the real approach speed -- all the binary's physics ever saw); Mech::Reset zeroes the mover motion (respawn = teleport); [collide-tx]/[mp-hdlr] telemetry. Gotcha #16 (engine-facility drift class). MISSILES: peer-visible salvos (the launcher record extension carries a salvo counter + aim point; ForceUpdate actually enqueues it -- the dirty flag alone never serialized), the authentic arc (authored MuzzleVelocity vector + the Seeker's 200m/0.1/300 loft + gain-4 steering, decoded from @004beae4/@004bef78), world-impact bursts (rounds detonate on cave geometry instead of phasing through), contact-only damage (flight-cap expiry = fizzle, no more teleport damage), live re-lead, and ballistic (unguided) shells for autocannons. projweap's stale BTPushProjectile extern (the /FORCE signature trap, gotcha #6 corollary) crashed the Avatar's first AFC100 shot -- fixed + sweep rule recorded. RADAR: two transcription bugs made the scope permanently empty -- FUN_0040b244 is the affine INVERSE (not a copy) and FUN_0040adec writes ONLY the 3x3 rotation (never the translation); worldToView now Invert(view) built rotation-first. CulturalIcons sorted out of the moving grid (the phantom red pips were map props), visible-radius culls on all three draw passes, live pip verified at |delta| x ppm px. Gotcha #17 (verify the FUN_ body, not its call shape). WEAPON PANELS (the frozen-dial hunt): the binary's *(subsystem+0x40) means FAILED -- the recon's 'operating' name was backwards, inverting the destroyed-X lamps, the panel look, the children enable and the ready-lamp gate (which had NEVER executed). Polarity chain corrected end-to-end (failedState, fed by real damage saturation). Root cause of the freezes: MFD page-mode gating -- the dev composite shows ALL pages at once, so off-page dials legitimately stopped; under BT_DEV_GAUGES the 15 page-plane bits stay active (the exclusive secondary trio untouched). The SEH gauge guard now names its kills; repaint-heal resets the incremental arc after panel repaints; [panel]/[arc] probes added. COMM/SCORE: MessageBoard LIVE (the engine already shipped the whole Player__StatusMessage queue; wired the binary's one producer -- the kill branch, victim's name, 6s -- plus the consumer bridge and a lazy source bind); MP DEATHS counted via the observed-death tally (each node scores every pilot from locally observed events, the same model as the KILLS credit) and the -2/-1 engine seed clamped for display. DEV UX: node-tagged window titles (-net port), gauge panel reworked (1320x480, true 4:3 MFD cells, the portrait secondary UNROTATED upright, linear filtering, BT_GAUGE_SCALE), fixed close spawns via BT_SPAWN_XZ, Boreas flies an Avatar (first second-chassis live outing).

platform profile + gauge dev-composite (Milestone A: gauge renderer woken)
PLATFORM PROFILE (-platform pod|dev / BT_PLATFORM / run.cmd pod; default dev): an env-preset selector, NOT a code fork -- it picks which environment the existing video/gauge/input code reads. dev = single 800x600 window + keyboard (the working build); pod = RIO input + (on real hardware) the multi-surface gauges/MFDs, mirroring content/SETENV.BAT (the pod path -- FindBestAdapterIndices / SVGA16 -- is left untouched). The multi-surface needs the pod's 2 video cards, so -platform pod does NOT auto-enable L4GAUGE on a dev box (stays bootable, single-window). Also fixes a real engine bug: SVGA16::BuildWindows PostQuitMessage'd on a CreateDevice failure but fell through to a null-device deref (segfault) -- now breaks (inert on the pod). GAUGE DEV-COMPOSITE, Milestone A (option B; opt-in BT_DEV_GAUGES, default OFF): wake the (dormant) gauge renderer so its CPU-rastered pixelBuffer can later be composited into the dev window, WITHOUT touching the pod SVGA16 output path. SVGA16 does no per-surface D3D in this mode (a DevGaugeComposite() gate forces the no-surface path + short-circuits Update/Refresh). Waking the never-exercised gauge subsystem exposed 4 latent reconstruction bugs, each guarded: SVGA16::Update / Refresh (empty mSurfaces[]), LBE4ControlsManager::MakeLinkedLamp (NULL lamp manager), L4GaugeRenderer::NotifyOfNewInterestingEntity (garbage warehouse chain). It now boots STABLY; the gauge reconstruction is incomplete (shadowed lamp-manager + warehouse members) -- Milestone B (the composite pass) will reveal whether the content is real. See docs/GAUGE_COMPOSITE.md. Verified: default DEV un-regressed (combat DESTROYED, 0 crashes); pod path untouched; BT_DEV_GAUGES boots stable.

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.
