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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
