A native PC port of Ace Combat 6: Fires of Liberation built on top of the ReXGlue SDK. The Xbox 360 PowerPC game code is statically recompiled to x86-64, while visible rendering currently remains authoritative in the vendored RexGlue/Xenia graphics backend.

The AC6-specific graphics layer in this repo is now focused on:

frame capture and diagnostics
swap-path inspection and overlay reporting
backend-fix routing for AC6-specific rendering issues
future selective override and modding hooks

The legacy AC6 replay renderer is still present as experimental tooling, but it is not the default render path and it does not hijack presentation unless ac6_graphics_mode=legacy_replay_experimental and ac6_experimental_replay_present=true.

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.

Build

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

The executable is placed at out/build/win-amd64-relwithdebinfo/ac6recomp.exe.

On Windows, use the preset commands above rather than plain cmake -L in the repo root. If you previously configured from an x86 Visual Studio prompt or with the wrong compiler on PATH, delete out/build/win-amd64-relwithdebinfo and re-run the preset from a normal 64-bit PowerShell/CMD window or an x64 Native Tools prompt.

Runtime Defaults

The default AC6 graphics configuration after this pivot is:

ac6_native_graphics_enabled=true
ac6_graphics_mode=hybrid_backend_fixes
ac6_render_capture=true
ac6_experimental_replay_present=false

That means the RexGlue/Xenia D3D12 backend remains the visible renderer by default, while AC6-specific analysis and diagnostics stay active.
