REDRIVERPC (Reverse-Engineered Driver PC)

Information

• This is the original Driver (Reflections Interactive, 1999), PC version — an AI-assisted decompilation: the executable is translated back to C function by function, with an AI agent working from the IDA database under the author's review.
• Work in progress. Every function is translated; the code is being verified against the original.
• The code keeps the original platform layer for now (Win32, DirectDraw / Direct3D 6 under the game's own Glide-to-Direct3D layer, DirectInput 5, DirectSound / EAX). A port to SDL and OpenGL comes after the decompilation is complete.
• For compatibility it currently uses the 3dfx Glide 2.x SDK headers (Glide types and constants) and runs through dgVoodoo 2 (DirectDraw / Direct3D wrapper).

How is it done?

• An IDA database of the PC executable with recovered names, types and data layout; the source tree is laid out like the original (game6.4g), and IDA function folders map to its files.
• The REDRIVER2 reconstruction of Driver 2 (same engine) is used for orientation — names and meanings of constants, structure of tangled code. The translation itself is always written from the binary.
• The 3dfx Glide 2.x SDK for the Glide types and constants used by the engine.
• Every function carries its address and status ([D] decompiled, [T] tested, [F] final, [A] altered on purpose), as in REDRIVER2. Details: CLAUDE.md.

Progress:

• WinMain, window and Direct3D initialisation through the Glide-to-Direct3D layer
• splash screens (copyright, GT Interactive, Reflections)
• frontend main menu: texture loading, CPU-drawn 8 bit screen, fonts, DirectInput, menu navigation and the quit question
• next: frontend sub-menus, then the game itself

How to build

Windows, Visual Studio 2022 (MSVC x86) and the Windows 10 SDK.

cd src_rebuild
gen_vc2022.bat          # generates build/OpenDriver1.sln with premake
build_vc2022.bat Debug  # or open the solution in Visual Studio

The game data is not included: point DRIVER_DATA_DIR (default ../data) at an installed copy of Driver; it is used as the working directory. A DirectDraw wrapper (dgVoodoo) from data\dgvoodoo is copied next to the exe, since modern systems offer no hardware Direct3D 6 device. More in docs/building.md.

How can I contribute?

Start with CLAUDE.md and the docs — they describe the workflow (function status marks, build, commit messages) for people and agents alike.

What's next

• Verify the decompilation against the original, then port to SDL and OpenGL.
