About

A byte-matching decompilation of the 2001 PC game Sheep, Dog 'n' Wolf (released in North America as Sheep Raider), PAL version, SheepD3D.exe. The README says all 3,305 game functions compile with Visual C++ 6.0 SP5 to the original's bytes, and the whole executable links to a byte-identical file. It says matching is complete but readability is not.

Getting started

Matching and building need the exact SheepD3D.exe with the SHA-1 given in the README; any other or patched executable fails the checks. The README points to tools for building the executable and a separate fixed build, and one generated header comes from your own copy of the game.

History

The README says almost all of the work was done with Claude and Codex coordinating through an MCP mailbox server, with in-game testing and technical knowledge from the Sheep Raider community.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Windows version).

How to install

Get the ready-made mod loader and example mods from the Releases page.

Summarised from the project's README.

Additional notes

Bug fixes: A fixes folder holds bug fixes as patches on top of the original source, built into a separate executable.
Stand in objects: 12 stand-in objects reproduce linker effects for object files whose code the linker discarded.
