The blocking identity is settled: DamageZoneClassID == 78 == 0x4e, computed from our own VDATA enum, so the binary's collector filter selects DAMAGE ZONES and the blast is shared across the mech's zones. Landed: AmmoBin::AmmoBinSimulation -- a Performance the class never had, installed under the same master+dynamic gate the binary's ctor uses -- and AmmoBin::CookOff. A bin whose fed weapon reaches heat failure latches a randomised fuse; when it burns down the bin is destroyed and its remaining rounds go off inside the mech, damage scaled by rounds remaining and SHARED across the zones, every victim announced. Correcting my own 5.3.136 write-up: heat clearing does NOT cancel the countdown. Both the arm gate and the cancel read the same cell -- the ammo alarm settled on spent -- so once armed, only spending or destroying the bin calls it off. Letting the gun cool does not save you. Live on the rig: three bins arm, the fuse spread sends them off on different frames rather than together, 20 rounds x 25 = 500 damage over 22 zones from one bin and 16 x 50 = 800 from another, feeding straight into the existing destruction cascade -- Searchlight and ThermalSight destroyed as a consequence. [T1] recorded: the per-round charge is a stand-in. The binary reads it from the bin's streamed explosion record, in the block our cookOffState reserves and nothing parses yet; we use the fed weapon's authored per-shot damage until that record is read. And a mistake worth keeping in the notes: the first attempt sourced the charge from heatPerRound, a heat figure of about 3e-9, so the detonation computed 4.8e-08 of damage and did precisely nothing -- a mechanic that fires, announces itself, and is silently inert. Only printing the arithmetic caught it. Log the numbers, not just the event. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Tesla Release 4.10 — Tesla:BattleTech & Tesla:Red Planet
Source code and game content for Tesla:BattleTech and Tesla:Red Planet, the two games that ran on the Tesla-generation simulator cockpits built by Virtual World Entertainment, Inc. (VWE). Source file headers are dated 1994–1996; this tree corresponds to release 4.10 of the Tesla software.
This repository is an archival snapshot. The tree is preserved byte-for-byte as
found (see .gitattributes — no line-ending conversion is applied).
See emulator/PLAN.md for the implementation plan to run these games on the surviving cockpits' Windows 10 computers via a VPX-board HLE device in DOSBox-X, with the cockpit RIO (COM1) and plasma display (COM2) passed through to the game's original drivers.
See HISTORY.md for findings from a recovered VWE developer hard drive that accompanies this tree (excluded from the repo), including Division renderer source, runnable game builds, unreleased prototypes (Star Trek, Hull Pressure, Renegade Legion, and the Starship Troopers pitch that became DisneyQuest's "Invasion!"), and an analysis of whether these games can be rebuilt from the sources in this repository (summary: the engine can, the games cannot — most game-logic sources are absent from this cut).
Target hardware
Each Tesla cockpit was driven by a server-class Pentium Pro machine running Novell DOS. Graphics were split across two adapters:
- The main (out-the-window) display was rendered by one of the first
pixel-pipeline 3D accelerator cards ever made, driven through Division Ltd.'s
dVS/DPL libraries (
libDPL— DPL, dsys, dvs, and the VPX headers; Division copyright 1995). - An S3 video adapter drove the other six cockpit displays (instrument
and gauge screens — see the
GAUGEcontent directories and thePCPIC.INC/L4GAU*gauge code).
Other hardware/OS interfaces:
- Audio: HMI SOS (Sound Operating System) —
sos/libraries, with variants for Borland (bc4) and Watcom (wc). - Networking: pods were networked over Ethernet using WATTCP (DOS TCP/IP, with BOOTP) via VWE's NetNub layer.
- Input: joystick/pedal/panel I/O in assembly (
JOYSTICK.ASM) and theL4CTRL*control modules.
Toolchain
- Borland C++ 5.0 (
BCC) with TASM32 for assembly — see the.MAKmakefiles (original build tree lived atD:\TESLA_RP\andD:\BC5\). - Precompiled-header discipline throughout (
.CSMheaders,#pragma hdrstop). VSSVER.SCC/MSSCCPRJ.SCCfiles are remnants of the original Visual SourceSafe source control.- File extensions:
.CPP/.HPPC++ source/headers,.TCP/.THPC++ template source/headers,.MAKBorland makefiles.

Both games share the same architecture: a portable simulation engine (MUNGA, VWE's in-house engine) plus a hardware layer (MUNGA_L4, the "L4" Tesla pod platform layer), with game-specific code and a game-specific L4 layer on top.
CODE/BT/ Tesla:BattleTech
BT/ Game logic: mechs, weapons (PPC, Gauss, missiles),
damage tables, teams, missions, scenario rules
BT_L4/ BattleTech pod application layer (app modes, arena,
radar, playback, version)
MUNGA/ Engine bricks: math (matrices, angles, splines),
containers, file streams, audio manager, events
MUNGA_L4/ Pod hardware layer: video renderer manager, keyboard,
mouse, audio hardware, warehouse (resource loading)
LIBDPL/ Division Ltd. dVS/DPL graphics library (headers +
LIBDPL.LIB + VREND*.BTL renderer modules)
NETNUB/ WATTCP-based pod networking (headers + WATTCPLG.LIB)
SOS/ HMI Sound Operating System libraries + drivers
CODE/RP/ Tesla:Red Planet (same structure)
RP/ Game logic: VTV (hover racer) power/subsystems,
pickups (booster, blocker, crusher, thruster)
RP_L4/ Red Planet pod application layer

original build (preserved as found)
Note: the BT copies of MUNGA/MUNGA_L4 are partial (69/68 files) while the RP copies are complete (351/231 files) — the BT tree appears to hold only the files that diverged from the shared engine.
