A native PC port of Ace Combat 6: Fires of Liberation (Xbox 360), built on top of the ReXGlue SDK. The Xbox 360 PowerPC binary is statically recompiled to x86-64 so the original game logic runs natively on your host CPU, with a fully native D3D12/Vulkan renderer replacing the original Xenos GPU pipeline.

Repository policy

This repository contains source code only.

Do not commit or redistribute:

retail game data
default.xex
disc images, packages, title updates, or firmware files
console keys or any other proprietary Microsoft / publisher material

Users must supply their own legally obtained game files locally.

Prerequisites

Tool	Version	Notes
CMake	3.25+
Ninja	any recent	required generator
Clang/LLVM	any recent	`clang` / `clang++` must be on `PATH`
Windows SDK	10.0.19041+	D3D12 headers (Windows only)

Note

The Linux preset uses clang-20 / clang++-20 directly. Install the versioned binaries via your distro's package manager (apt install clang-20) or via the LLVM APT repository.

Acquiring the game files

Obtain the original Xbox 360 disc image (ISO) by dumping your own disc.
Guides and tools: consolemods.org – ISO Extraction & Repacking
Extract the XEX and game data from the ISO.
Place the resulting files inside the assets/ directory (created manually — it is git-ignored):

assets/
  default.xex        ← required by the codegen step
  media/             ← game data (audio, video, maps, …)
  …

Clone

git clone https://github.com/sal063/AC6_recomp.git
cd AC6_recomp

Note

The ReXGlue SDK (thirdparty/rexglue-sdk/) is vendored directly in the repository. No submodule init is needed.

Build

1 — Generate the recompiled code (first time, and after updating `default.xex`)

cmake --preset win-amd64-relwithdebinfo
cmake --build --preset win-amd64-relwithdebinfo --target ac6recomp_codegen

This step reads assets/default.xex, lifts all PowerPC instructions to C++, and writes the output to generated/. It can take a few minutes.

2 — Build the runtime

cmake --build --preset win-amd64-relwithdebinfo

The executable is placed at:

out/build/win-amd64-relwithdebinfo/ac6recomp.exe

Tip

RelWithDebInfo is the recommended preset — it gives near-release performance with symbols intact for debugging. A full Release build disables assertions and can be used for distribution.

Available presets

Preset	Platform	Build type
`win-amd64-debug`	Windows	Debug
`win-amd64-release`	Windows	Release
`win-amd64-relwithdebinfo`	Windows	RelWithDebInfo ✅ recommended
`linux-amd64-debug`	Linux	Debug
`linux-amd64-release`	Linux	Release
`linux-amd64-relwithdebinfo`	Linux	RelWithDebInfo

Run

./out/build/win-amd64-relwithdebinfo/ac6recomp assets

The single argument is the path to the directory containing your game files (assets/ by default). The runtime resolves all paths relative to it.

Linux

Substitute win-amd64-relwithdebinfo with linux-amd64-relwithdebinfo in every command above.

cmake --preset linux-amd64-relwithdebinfo
cmake --build --preset linux-amd64-relwithdebinfo --target ac6recomp_codegen
cmake --build --preset linux-amd64-relwithdebinfo
./out/build/linux-amd64-relwithdebinfo/ac6recomp assets
