FNC Reborn

An unofficial native Windows port of Fight Night Champion (Xbox 360, 2011). The game's PowerPC code is statically recompiled to x86-64 with the ReXGlue SDK, so it runs as a normal Windows program rather than under an emulator.

This repository contains no game code or data. You build the game yourself, on your own PC, from your own disc.

FNC Reborn is a fan project. It is not affiliated with, endorsed by or sponsored by Electronic Arts, EA Sports or Microsoft.

Status

Playable. The menus, Fight Now, Legacy mode, Champion mode, Create a Fighter and saving and loading all work, with sound. The game runs at 60 FPS by default (30, 120 and 144 are one setting away) and has its own DISPLAY tab in the Settings screen for frame rate, VSync, resolution scale, anti-aliasing and fullscreen. A camera behind your boxer is one button away (Back on the controller). Older CPUs are covered: the build adapts to the CPU of the PC it is built on.

Known issues

• Fighters can occasionally disappear for a moment after skipping an in-fight cinematic.
• Some menu text flickers slightly.
• The short cutscene right after a fight shows nothing.
• Only the disc version this port was made with is supported. Setup warns if your default.xex is different.

Easy install

Download FNCReborn-Setup.exe from the latest release, run it, choose your .iso or a folder with your game files (the one with default.xex and databigs in it), and press Install.

Setup downloads everything it needs: clang, CMake, Ninja, Microsoft's C++ headers and libraries, and Git if you don't have it. That is about 2.5 GB, all kept in the install folder, and no Visual Studio is needed. Windows only asks for permission if the Visual C++ runtime is missing. Setup then builds the game, adds the DISPLAY tab to the Settings screen and adds an FNC Reborn shortcut. The first build takes 15–60 minutes, depending on your CPU. You need about 25 GB of free disk space.

To update, run Setup again or use the Update FNC Reborn shortcut. Only what changed is rebuilt, and your saves and settings are kept.

Requirements (manual build with setup.bat)

• Your own Fight Night Champion (Xbox 360) disc, dumped to an .iso file.
• Windows 10 or 11 (64-bit) and a GPU with Direct3D 12 support.
• Visual Studio 2022 (Community or Build Tools, both free) with the Desktop development with C++ workload and these individual components:
  • C++ Clang Compiler for Windows
  • C++ CMake tools for Windows
• Git for Windows.
• Optional: Python 3, for the DISPLAY tab in the Settings screen. Without it the game works the same; the settings are then only in dist\FNCReborn.toml.
• About 25 GB of free disk space and 16 GB of RAM. The first build takes 30–90 minutes depending on your CPU.

Building manually

1. Download this repository to a short path, for example C:\FNCReborn.
2. Run setup.bat.
3. Select your Fight Night Champion .iso when asked.

When it finishes, the game is in the dist folder. If a step fails, fix the cause and run setup.bat again; finished steps are skipped. See docs/BUILDING.md for what each step does and for troubleshooting.

Playing

Run dist\FNCReborn.exe. An Xbox controller works as on the console.

Key / button	Effect
Back (View on newer controllers) or F2	Switch between the TV camera and a camera behind your boxer
F11	Fullscreen / window
F1	Frame rate counter

Saves are stored in Documents\FNCReborn.

Settings

Most settings are in the game's Settings screen under DISPLAY. Everything is also in dist\FNCReborn.toml (setup creates it once and never overwrites it). The useful ones:

Setting	Effect
fnc_frame_rate	Frame rate cap: 30 (original), 60 (default), 120 or 144
vsync	true or false
resolution_scale	Internal resolution: 1 (720p) or 2 (1440p)
fullscreen	Start in fullscreen (true) or a window (false)
texture_cache_memory_limit_soft / _hard	Texture memory in MB. Lower to 1024 / 2048 on a GPU with 4 GB or less
fnc_tp_back, fnc_tp_height, fnc_tp_side, fnc_tp_fov	Position and zoom of the camera behind your boxer
fnc_tp_smooth	How smoothly that camera follows (0 rigid to 0.95 very floaty)
fnc_view_boxer	Set to 1 if that camera follows your opponent instead of you
fnc_view_first_person	true turns that camera into a first-person view

How it works

The ReXGlue SDK translates every PowerPC function in the game's executable to C++ and reimplements the Xbox 360 kernel, GPU (on Direct3D 12), audio and input. This repository adds the Fight Night Champion-specific parts:

Path	Contents
config/fnc_manifest.toml	Recompiler configuration: functions static analysis misses
config/FNCReborn.toml	Default settings
project/src/fnc_hooks.cpp	Frame rate unlock
project/src/player_camera.cpp	The camera behind your boxer
project/src/fnc_settings_menu.cpp	Values for the DISPLAY tab
project/src/fnc_fps_overlay.cpp	F1 frame rate counter, F11 fullscreen
project/src/fnc_sampler.cpp	Crash reports and an optional profiler
patches/rexglue-sdk.patch	Changes to the SDK that the game needs
installer	FNC Reborn Setup (the one-click installer)
tools/xiso_extract	Xbox disc image (XDVDFS) extractor
tools/display_tab	Adds the DISPLAY tab to your copy of the game's Settings screen
scripts/setup.ps1	The build script behind setup.bat

docs/HOW_IT_WORKS.md explains the individual fixes.
