Fight Night Champion Recompiled

Fight Night Champion Recompiled

A work-in-progress native Windows port of Fight Night Champion (Xbox 360, 2011) 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 and Conan Recompiled.

This repository contains no game data. You need your own copy of Fight Night Champion (title ID 45410915). The build extracts your disc and generates the C++ on your machine; nothing derived from the game is ever committed.

Status

Playable. Menus, Champion mode, fights and saving work. Still early: please report anything that goes wrong with fightnight.log (next to the game's exe).

Features

• Native x64 Windows build of the game's own code, no emulator.
• Higher resolutions (resolution_scale 1-3: 720p, 1440p, 4K) with SMAA / FXAA, AMD FSR / CAS or NVIDIA Image Scaling, and 16x anisotropic filtering.
• Frame rate unlock from 30 up to 360 FPS (F6 cycles in game): only the render loop speeds up, the fight simulation keeps the game's fixed 60 Hz.
• Controllers through SDL (Xbox, PlayStation and others), rumble.
• Saves in game\hdd with automatic backups; achievements with pop-ups.
• Settings overlay (F1), screenshots (F12), brightness / contrast / gamma / colour.
• Hold Back on the pause menu to quit to desktop.
• Launcher with settings and one-click updates.

Installing (Windows 10/11, 64-bit)

You need your own Fight Night Champion disc image (tested with Fight Night Champion (USA, Europe) (En,Fr,De)), or the folder of an already extracted disc, and about 15 GB of free space.

1. Download FightNightSetup.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 Fight Night Champion 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/fightnight-recomp.git
   cd fightnight-recomp
   python tools\build.py --iso "D:\path\to\FightNight.iso"
   

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

3. Run build\runtime\FightNightLauncher.exe (settings, then Play) or build\runtime\FightNightRecomp.exe. Problems: include fightnight.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/FightNight_config.toml and config/FightNight_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.
