3D Pinball for Windows – Space Cadet

Summary

Reverse engineering of 3D Pinball for Windows – Space Cadet, a game bundled with Windows.

About the original game

3D Pinball for Windows – Space Cadet is a pinball video game developed by Cinematronics and published by Maxis in 1995. It features pre-rendered 3D graphics and three tables—Space Cadet, Skullduggery, and Dragon's Keep. On each table, there are displays on the side that show the players' score, ball number, player number, a display for various information and a table-specific image.

How to play

Place compiled executable into a folder containing original game resources (not included).
Supports data files from Windows and Full Tilt versions of the game.

Use your keyboard or mouse to control the flipper

Platforms covered by this project: desktop Windows, Linux and macOS.







Source

  • pinball.exe from Windows XP (SHA-1 2A5B525E0F631BB6107639E2A69DF15986FB0D05) and its public PDB
  • CADET.EXE 32bit version from Full Tilt! Pinball (SHA-1 3F7B5699074B83FD713657CD94671F2156DBEDC4)

Tools used

Ghidra, Ida, Visual Studio

What was done

  • All structures were populated, globals and locals named.
  • All subs were decompiled, C pseudo code was converted to compilable C++. Loose (namespace?) subs were assigned to classes.

Compiling

Project uses C++11 and depends on SDL2 libs.

On Windows

Download and unpack devel packages for SDL2 and SDL2_mixer.
Set paths to them in CMakeLists.txt, see suggested placement in /Libs.
Compile with Visual Studio; tested with 2019.

On Linux

Install devel packages for SDL2 and SDL2_mixer.\

Compile with CMake; tested with GCC 10, Clang 11.
To cross-compile for Windows, install a 64-bit version of mingw and its SDL2 and SDL2_mixer distributions, then use the mingwcc.cmake toolchain.

# On Debian and Ubuntu
sudo apt install cmake build-essential ninja-build libsdl2-dev libsdl2-mixer-dev libsdl2-mixer-2.0-0 libsdl2-2.0-0 fluidsynth

# On Fedora
sudo dnf install cmake ninja-build SDL2 SDL2-devel SDL2_mixer SDL2_mixer-devel fluidsynth fluidsynth-libs mscore-fonts g++

# Build
cmake -GNinja .
ninja

Packaging status

Some distributions provide a package in their repository. You can use those for easier dependency management and updates.

Fixing the audio issue: To make music work, you need to export the following envar before launching the game: SDL_SOUNDFONT=/path/to/soundfont On Fedora: SDL_SOUNDFONT=/usr/share/soundfonts/FluidR3_GM.sf2 On Ubuntu/Debian: SDL_SOUNDFONT=/usr/share/sounds/sf2/FluidR3_GM.sf2

On macOS

  • Homebrew: Install the SDL2, SDL2_mixer homebrew packages.
  • MacPorts: Install the libSDL2, libSDL2_mixer macports packages.

Compile with CMake. Ensure that CMAKE_OSX_ARCHITECTURES variable is set for either x86_64 Apple Intel or arm64 for Apple Silicon.

Tested with: macOS Big Sur (Intel) with Xcode 13 & macOS Montery Beta (Apple Silicon) with Xcode 13.

Plans

  • Decompile original game
  • Resizable window, scaled graphics
  • Loader for high-res sprites from CADET.DAT
  • Cross-platform port using SDL2, SDL2_mixer, ImGui
  • Misc features of Full Tilt: 3 music tracks, multiball, centered textboxes, etc.
  • Maybe: Text translations
  • Maybe: Android port
  • Maybe x2: support for other two tables
    • Table specific BL (control interactions and missions) is hardcoded, othere parts might be also patched

On 64-bit bug that killed the game

I did not find it, decompiled game worked in x64 mode on the first try.
It was either lost in decompilation or introduced in x64 port/not present in x86 build.
Based on public description of the bug (no ball collision), I guess that the bug was in TEdgeManager::TestGridBox
