Conan Recompiled

A work-in-progress native Windows port of Conan (Xbox 360, 2007) made by static recompilation: the game's PowerPC code is translated to C++ and compiled for x64, then run on a small runtime that plays the part of the console. Graphics and audio use Xenia's GPU and audio emulation; the recompiler is XenonRecomp.

It is built on the runtime, launcher and tools of WET Recompiled.

This repository contains no game data. You need your own copy of Conan (title ID 545107DA). The build extracts your disc and generates the C++ on your machine; nothing derived from the game is ever committed.

Status

Early release (0.1.x). The game boots, plays its videos and is playable (tested through the first levels) with sound, saves and achievements. Expect bugs; please include conan.log with any report (the launcher's Report a bug... button zips the logs for you).

What's in it:

• Resolution 720p / 1440p / 4K, frame rate 30 up to 360 FPS (or your monitor's), V-Sync, borderless fullscreen and monitor choice.
• Anti-aliasing (FXAA, SMAA), AMD FSR / CAS and NVIDIA Image Scaling, 16x texture filtering, brightness / contrast / gamma / colour.
• Keyboard and mouse (rebindable), any controller through SDL, vibration.
• Button prompts for Xbox, PlayStation or keyboard / mouse (automatic by default).
• Achievements with pop-ups, save backups, shader cache.

Installing (Windows 10/11, 64-bit)

You need your own Conan disc image (tested with Conan (World) (En,Fr,De,Es,It)), or the folder of an already extracted disc, and about 12 GB of free space.

1. Download ConanSetup.exe from the latest release.
2. Run it, choose your disc image (or extracted folder) and a folder to install to, and press Install. It downloads the build tools it needs (Git, CMake, Ninja, Clang, Python), gets this source code, extracts your disc and builds the game on your PC. The first build takes a while (10-30 minutes).
3. Start Conan Recompiled from the desktop shortcut: the launcher has the settings, then press Play. In game, F1 opens the settings overlay.

The launcher's Check for updates / Update now gets and builds new releases; your saves and settings stay.

Building by hand

1. Install Python 3 (tick "Add python.exe to PATH"), Git for Windows, CMake and Ninja (pip install cmake ninja) and the latest llvm-mingw release (llvm-mingw-<date>-ucrt-x86_64.zip from github.com/mstorsjo/llvm-mingw/releases), unzipped with its bin folder on your PATH.

2. Build:

   git clone --recursive https://github.com/zonehammer/conan-recomp.git
   cd conan-recomp
   python tools\build.py --iso "D:\path\to\Conan.iso"
   

   This extracts the disc into game\extracted, recompiles default.xex into generated\ppc and builds everything.

3. Run build\runtime\ConanLauncher.exe (settings, then Play) or build\runtime\ConanRecomp.exe. Problems: include conan.log (next to the exe).

How it works

1. tools/prepare_game.py extracts the disc into game/extracted/.
2. A patched XenonRecomp translates default.xex into C++ files in generated/ppc/, guided by config/Conan_config.toml and config/Conan_switch_tables.toml (tools/fix_switch_bounds.py sizes functions whose jump tables run past the analyser's estimate).
3. runtime/ provides what the console did: guest memory, threads and synchronisation, files, input, achievements and the kernel/XAM functions.
4. The GPU commands the game submits run through Xenia's command processor and shader translator; XMA audio is decoded by Xenia's decoder and played with XAudio2.
