pyr0ball 6311ecb69e chore: untrack debug screenshot artifact, ignore future MCP client config 
tools/debug_screenshot_gameplay.png was a one-off capture from testing the
runtime-observation MCP's screenshot tool, not something that belongs in
version control. Also ignore .mcp.json (local MCP server registration) and
future tools/debug_screenshot*.png captures.

Havoc — Preservation & Godot Remaster

Reverse-engineering, asset-extraction, and Godot remaster of Havoc (Reality Bytes, Inc., 1995) — a first-person vehicular-combat shooter for Windows 95/98.

Havoc renders a software-rasterized 3D world (textured terrain, low-poly enemy/pickup models, drivable and flyable vehicles, dithered 8-bit color) into a DirectDraw framebuffer, framed by an elaborate 2D cockpit HUD (mirrors, radar, gauges, weapon icons). Biomes include desert, snow/ice, lava, and ocean.

The original 32-bit executable (DirectDraw + DirectSound, no Direct3D — the 3D is all software) no longer runs reliably on modern Windows (legacy DirectDraw + a 16-bit installer/DirectX setup path). Rather than only emulate it, this project extracts the original data into open formats and rebuilds the game in Godot as a quality-of-life remaster.

Legal: Havoc is 30-year-old abandonware. This repository contains only original reverse-engineering code and documentation. It does not redistribute the game's executables, DLLs, or data files (see .gitignore). You must supply your own copy of the game data to run the tools.

Status

  • Identified binaries: HAVOC.EXE/LAUNCHER.EXE/SETUP.EXE are 32-bit PE (i386), DirectDraw + DirectSound, not 16-bit/DOS.
  • Cracked the .FF ("FlashFile") archive format — see docs/FORMATS.md.
  • Extracted MUSIC.FF: 97 WAV segments + 17 playlist-sequenced songs (verified correct).
  • FL Studio pack: per-song MIDI + sample mapping (tools/ff_extract.py --fl).
  • ogg/mp3 conversion (--convert, needs ffmpeg).
  • Boot HAVOC.EXE on Windows 11 (dgVoodoo2) — NOCD + copy-protection fix, see docs/PATCHES.md.
  • [~] Crack graphics formats: GRAFIX*.DAT done (docs/FORMATS.md); LAND*.DAT, MAP*.MAP, STUF*.DAT next.
  • Decompile HAVOC.EXE (Ghidra) to recover game logic.
  • Godot remaster project (widescreen, higher-res, rebindable input).

Tools

tools/ff_extract.py — extract any .FF archive.

python tools/ff_extract.py MUSIC.FF -o out_music --songs          # raw entries + assembled songs
python tools/ff_extract.py MUSIC.FF -o out_music --songs --convert ogg
python tools/ff_extract.py MUSIC.FF -o Havoc_MUSIC_FLStudio --fl  # FL Studio samples + MIDI
