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 GAUGE content directories and the PCPIC.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 the L4CTRL* control modules.

Toolchain

• Borland C++ 5.0 (BCC) with TASM32 for assembly — see the .MAK makefiles (original build tree lived at D:\TESLA_RP\ and D:\BC5\).
• Precompiled-header discipline throughout (.CSM headers, #pragma hdrstop).
• VSSVER.SCC / MSSCCPRJ.SCC files are remnants of the original Visual SourceSafe source control.
• File extensions: .CPP/.HPP C++ source/headers, .TCP/.THP C++ template source/headers, .MAK Borland makefiles.

CODE/

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
  MUNGA/                Engine (fullest copy — 351 files incl. all .CPP)
  MUNGA_L4/             Pod hardware layer (fullest copy, incl. JOYSTICK.ASM)
    libDPL/, NetNub/, sos/   as above
  */opt/                Compiled Borland C++ 5.0 object files from the
                        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.

CONTENT/

CONTENT/BT/             Tesla:BattleTech content
CONTENT/BT3025/         Parallel BattleTech content set (3025-era variant;
                        mostly identical to BT/ with a different mech roster)
CONTENT/RP/             Tesla:Red Planet content

Per-game content directories:

ANIMS	.ANI — animations (BT only)
AUDIO	.MID MIDI music, .SCP audio scripts, .BNK/.BLD banks
