The core 'single-player without the operator console' capability: a
zero-argument launch now builds its own mission and plays.
- game/reconstructed/btl4fe.{hpp,cpp}: the BattleTech catalog (8 maps,
8 mechs + variants, colors) and BTFeMission_WriteEgg -- emits the exact
console egg format (verified against content/MP.EGG): [mission],
[ordinals] + the 4 static rank-place plasma bitmaps, [pilots],
per-pilot loadout sections, and [largebitmap]/[smallbitmap] with
GDI-rendered 128x32 / 64x16 pilot-name plasma bitmaps.
- L4APP.H: SetEggNotationFileName / SetNetworkCommonFlatAddress setters
(from RP412) so the front end feeds the standard -egg load path.
- btl4main.cpp WinMain: front-end mode -- no -egg and no -net builds
frontend.egg locally (BTFrontEnd_Run) and boots it. -egg/-net runs
are untouched.
Verified: no-args launch -> '[frontend] built frontend.egg' -> mission
loads and runs; the generated egg is structurally identical to MP.EGG
(32x32/16x16 name bitmaps with real glyph pixels, all sections present).
Remaining in Phase 5 (deferred): the interactive on-screen catalog menu,
the in-process LocalConsole marshal (mission clock + StopMission at
expiry + single-binary loop), and the score-intake/results screen (new
for BT -- no mission-end flow exists yet). (Phase 5 of the roadmap)

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.
