Correct the audio digest in wintesla-port.md + project-overview.md: the "no sound ever" root cause was that BOTH engine/lib backend DLLs were no-op stubs (libsndfile ordinal-only sf_open->NULL; OpenAL32 imports only KERNEL32). Now real OpenAL Soft + LoadWavPCM; soundbank cracked (241 samples). Only remaining gap = game triggering (AudioEntities). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Project Overview
|
|
|
|
Port VWE's arcade **pod** games (Tesla platform, release 4.10, ~1995-96) to modern Windows and,
|
|
ultimately, the actual arcade pod hardware. Primary target: **BattleTech (BT)**; **Red Planet
|
|
(RP)** shares the engine. Full detail: `docs/PROGRESS_LOG.md §1-3`.
|
|
|
|
## The stack
|
|
- Two games, one engine: BT + RP. Engine = **MUNGA**; HAL = **L4** (`MUNGA_L4`). Game logic =
|
|
`CODE/BT`, `CODE/RP`. [T1]
|
|
- Original platform: **32-bit DOS** under a **DPMI32** extender, Borland C++ 5 + TASM32, on Novell
|
|
DOS pods. 3D by a proprietary Division **IG image-generator board** (dual EISA), driven by the
|
|
closed **`libDPL.lib`** (binary + VREND microcode). [T1]
|
|
- **The port replaces the IG board/libDPL** with a `dpl_*` → Direct3D9 shim (done in WinTesla as
|
|
L4D3D). Pods now run Windows 10 + a Voodoo/Glide wrapper. BT was abandoned (MechWarrior 4 runs on
|
|
the current pods); this project revives BT. [T1]
|
|
|
|
## People / goals
|
|
- **arcattack** (user): doing the port. NVIDIA 3060 + A6000 dev GPUs.
|
|
- **Nick:** owns the pods + the software license (porting is authorized). Runs the pod hardware. The
|
|
gating dependency — the missing BT source likely lives on his backup drives (see [[source-completeness]]).
|
|
- **Goal:** run on (a) a modern dev box and (b) the fixed pod hardware. Multiplayer (pod-to-pod) wanted.
|
|
|
|
## Repo orientation (bt411)
|
|
This is the **clean standalone bt411 repo**. `README.md` + the top-level `CMakeLists.txt` are the
|
|
build of record. Tree: `engine/ game/ content/ docs/ reference/ tools/ context/`. Historical
|
|
sections in `docs/PROGRESS_LOG.md` cite old `C:/git/nick-games/...` paths — treat as provenance;
|
|
they map into this repo (reconstructed BT → `game/reconstructed/`, engine → `engine/MUNGA{,_L4}/`,
|
|
content → `content/`, raw decomp → `reference/decomp/`). [T2]
|
|
|
|
## Current state (2026-07)
|
|
`btl4.exe` boots, renders the world + a skinned mech, and runs a full **drive → animate → target →
|
|
fire → damage → destroy → respawn** single-player loop (task #52). **2-node MP is verified
|
|
end-to-end** — replication, cross-pod targeting/damage/kill, beam visuals, replicant gait (tasks
|
|
#46-#51, [[multiplayer]]). All 8 cockpit canopies are authentic + the horizontal-FOV fix (task #55,
|
|
[[cockpit-view]]); the Gyroscope is live byte-exact with hit-bounce (task #56); the **gauge system
|
|
is complete** ([[gauges-hud]]). The engine/renderer/HAL are done (WinTesla); AUDIO backend is now REAL
|
|
(the repo's OpenAL32.dll + libsndfile-1.dll were both no-op STUBS — replaced with real OpenAL Soft +
|
|
an in-tree WAV loader, 2026-07-15) and the 241-sample soundbank is cracked from AUDIO1/2.RES + loading;
|
|
the ONLY remaining audio gap is game-triggering (no AudioEntities fire PlayNote yet), so gameplay is
|
|
still silent apart from a proof-of-life hook (see [[wintesla-port]] Audio). The active work
|
|
is reconstructing each BT subsystem's authentic behavior from the binary. Remaining: pod-LAN
|
|
config, Mech-level update records, per-subsystem waves. [T2]
