Archival snapshot of the Virtual World Entertainment Tesla cockpit software, 1994-1996: MUNGA engine and L4 pod layer source (Borland C++ 5.0), BT/RP game code, and game content (models, audio, maps, gauges, Division renderer data). Includes third-party libraries: Division dVS/DPL graphics, HMI SOS audio, WATTCP networking. Files are preserved byte-for-byte (.gitattributes disables all line-ending conversion). README.md documents the layout, target hardware, and toolchain. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
