Ported from RP412: RIOBase split out of the serial RIO (L4RIO.h),
rioPointer is RIOBase* (L4CTRL.h), PAD token -> new PadRIO() speaking
the RIO surface from an XInput pad + keyboard (L4PADRIO/L4PADBINDINGS,
vRIO bindings.txt grammar, hot-plug), KeyLight RGB mirror TU
(BT412KEYLIGHT, /std:c++17 per-file).
BT-side fixes PadRIO forced into the open:
- Both keyboard input bridges (mech4.cpp, mechmppr.cpp BT_KEY_BRIDGE)
stand down when a RIO device exists -- they overwrote the engine
controls push every frame. M/X conveniences stay live.
- Mapper attribute chain OFF BY ONE (latent real-pod bug): the DOS
chain below MechControlsMapper carried two base attributes, WinTesla
carries one, and AttributeIndexSet::Find is positional -- the .CTL
stick mapping wrote throttlePosition. Pad slot + binary-locked enum;
gotcha ledgered (reconstruction-gotchas #11).
Verified: PAD throttle lever ramps + sticks, stick turns with the
authentic speed-vs-turn clamp (61.5 -> 22.0 u/s), mech drives; keyboard
fallback intact (BT_FORCE_THROTTLE harness). New diags: BT_CTRLMAP_LOG,
BT_STICK_LOG. (Phase 2 of docs/BT412-ROADMAP.md)

The v143 linker refuses to emit an image with unresolved externals even
under /FORCE, so the dead offline-tool ladders in mech3.cpp
(Mech::CreateSubsystemStream / SubsystemDefaultData -- never called at
runtime, resources ship prebuilt in BTL4.RES) are compiled out behind
BT412_OFFLINE_TOOLS (default off). The exe links /FORCE:MULTIPLE only:
a genuinely unresolved symbol is now a hard link error instead of a
hidden runtime AV. No other source changes needed for v143.
Verified: clean build; solo DEV.EGG runs; two-instance loopback MP via
btconsole.py -- mesh forms, mission runs both sides, master + replicant
tick in each world. (Phase 1 of docs/BT412-ROADMAP.md)

Identity pass (README/CLAUDE.md/CMake project bt412), the steamification
roadmap (docs/BT412-ROADMAP.md), and the living context topic
(context/steamification.md). Forked at BT411 4e72f0c; origin is
VWE/BT412.git only -- this repo never touches the BT411 remote.

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.
