# NCAA Football 14 Recompiled

A native Windows and Linux port of NCAA Football 14 (Xbox 360), made with
the [ReXGlue SDK](https://github.com/rexglue/rexglue-sdk). You need your own
disc image. No game content is included here or in the releases.

## Playing

Download from the Releases page.

- **Windows:** extract the zip anywhere and run `ncaafootball14.exe`. Windows
  will say it protected your PC because the build is not signed: More info,
  then Run anyway.
- **Linux:** make the AppImage executable and run it.

On first run the launcher asks for your disc image (`.iso`) and extracts it.
It then offers College Football Revamped if you have the mod's files: one
folder holding its six archives with `DLC.rar` beside them. The launcher
unpacks and installs the packages. After that it opens straight to PLAY.

Requirements: 64-bit Windows 10 or newer with a Direct3D 12 GPU, or a
Linux distribution with glibc 2.35 or newer (Ubuntu 22.04, Debian 12,
Fedora 36, SteamOS 3.5 or anything more recent) with a Vulkan GPU; a
processor with SSE4.2.

Everything the game writes lives in `%LOCALAPPDATA%\ncaafootball14` on
Windows and `~/.local/share/ncaafootball14` on Linux.

## Building from source

The build needs the SDK from the `ncaa14` branch of
[LegendaryDoors/rexglue-sdk](https://github.com/LegendaryDoors/rexglue-sdk),
CMake 3.25 or newer, Ninja, Clang 18 or newer, Python 3, and your own disc
image. The two checkouts sit side by side.

**1. Build and install the SDK.**

```sh
git clone -b ncaa14 https://github.com/LegendaryDoors/rexglue-sdk.git
cmake -S rexglue-sdk --preset linux-amd64 -DREXGLUE_ENABLE_TRACY=OFF
cmake --build rexglue-sdk/out/build/linux-amd64 --config Release --target install --parallel
```

**2. Take the game's executable from your disc.**

```sh
cd NCAAFootball14Recomp
python3 tools/extract_iso.py "NCAA Football 14 (USA).iso" game
mkdir -p assets/game && cp game/default.xex assets/game/
```

Only `default.xex` goes there, never the title update's `default.xexp`: the
update moves every address in the program, and this recompilation, like
College Football Revamped on the console, targets the disc's version
`0.0.0.2`. The disc's `default.xex` is 31,870,976 bytes, SHA-1
`f2d268ae652c92bb5650a7d9c2d227f325a409c7`.

**3. Generate the recompiled code and build the game.**

```sh
../rexglue-sdk/out/install/linux-amd64/bin/rexglue codegen ncaafootball14_manifest.toml
cmake --preset linux-amd64-release -DCMAKE_PREFIX_PATH=../rexglue-sdk/out/install/linux-amd64
cmake --build out/build/linux-amd64-release --target ncaafootball14 --parallel
```

On Windows, `tools\win_build_sdk.bat` and `tools\win_build_app.bat` run
the same steps with the Windows presets; a release build passes
`-DCMAKE_C_FLAGS=-march=x86-64-v2 -DCMAKE_CXX_FLAGS=-march=x86-64-v2` to
both, which is where the SSE4.2 requirement comes from.
`tools/release_linux.sh` builds the release AppImage inside an Ubuntu 22.04
container, and `tools\release_windows.ps1` builds the Windows zip.
