# FFNx

Next generation modding platform for Final Fantasy VII and Final Fantasy VIII (with native Steam 2013, Steam 2026 Rerelease, GOG and Windows Store support)

## Introduction

FFNx is a continuing evolution of the [FF7_OpenGL](https://github.com/Aali132/ff7_opengl) driver, [made by Aali](http://forums.qhimm.com/index.php?topic=14922.0).

FFNx today in a nutshell:

- Uses an easy, drag-n-drop installation experience, see [How to Install](docs/how_to_install.md)
- Comes built-in with 7th Heaven v2.3 and higher
- Supports the newest video and audio codecs (WEBM, H.265, Ogg, etc.)
- Drastically enhances the gameplay experience compared to the vanilla experience
- Provides four stable rendering backends:
  - DirectX 11 (default)
  - DirectX 12
  - Vulkan
  - OpenGL

## The Team

FFNx is developed by a core team, currently composed of:

- [Julian Xhokaxhiu](https://github.com/julianxhokaxhiu) (TrueOdin, 🇪🇸 Spain)
- [Tang-Tang Zhou](https://github.com/tangtang95) (vertex2995, 🇮🇹 Italy)
- [Jérôme Arzel](https://github.com/myst6re) (myst6re, 🇫🇷 France)
- [CosmosXIII](https://github.com/CosmosXIII) (Cosmos, 🇯🇵 Japan)

We are always open for contributions via PRs, and in case you want to join the core team, feel free to approach us on Discord and we will evaluate on a case-by-case basis.

## How to build

Available build profiles:

- x86-Release (default, the same used to release artifacts in this Github page)
- x86-RelWithDebInfo (used while developing to better debug some issues)
- x86-MinSizeRel
- x86-Debug (prefer it if you want to use a debugger attached to the game)

Once the project is built you can find the output in this path: `.build/bin`

### Preparation

> **Please note:**
>
> FFNx uses vcpkg as a package manager to resolve dependencies. Failing to follow these steps will result in build errors.

0. Clone this repository using the `--recursive` flag, eg. `git clone --recursive https://github.com/julianxhokaxhiu/FFNx.git`

### NuGet

> **Please note:**
>
> This step will speed up your compilation times by avoiding the vcpkg dependencies rebuild.

0. Make sure you have [NuGet CLI installed](https://learn.microsoft.com/en-us/nuget/install-nuget-client-tools?tabs=windows#install-nugetexe).
1. [Create a Personal Access token ( classic )](https://github.com/settings/tokens/new) with the `read:packages` permission.
  This setup is read-only and is only used to consume prebuilt packages.
2. Open a `cmd` window and run the following commands ( replace `YOUR_GITHUB_USERNAME` and `YOUR_GITHUB_PAT` accordingly ):
```pwsh
$ nuget sources add -Name github -Source "https://nuget.pkg.github.com/julianxhokaxhiu/index.json" -Username YOUR_GITHUB_USERNAME -Password YOUR_GITHUB_PAT -StorePasswordInClearText
$ nuget setApiKey YOUR_GITHUB_PAT -Source "https://nuget.pkg.github.com/julianxhokaxhiu/index.json"
$ [Environment]::SetEnvironmentVariable("VCPKG_BINARY_SOURCES", "clear;nuget,github,read;default,readwrite", "User")
```

### Visual Studio

> **Please note:**
>
> By default Visual Studio will pick the **x86-Release** build configuration, but you can choose any other profile available.
> FFNx uses vcpkg as a package manager to resolve dependencies. Failing to follow these steps will result in build errors.

3. Go inside the [`vcpkg`](./vcpkg) folder and double click `bootstrap-vcpkg.bat`
4. Open a `cmd` window in [`vcpkg`](./vcpkg) and run the following command: `vcpkg integrate install`
5. Once installed, open this repository **as a folder** in Visual Studio
6. Choose as preset in the status bar the one you desire
7. Click the `Build` button

### Visual Studio Code

4. Choose as preset in the status bar the one you desire
5. Click the button on the status bar `Build`

### Neovim with clangd (optional)

0. **REQUIRED!** Follow up the steps to install Visual Studio, which will also install the MSVC toolchain
1. **REQUIRED!** Have [Neovim](https://neovim.io/) installed with [clangd](https://clangd.llvm.org/) as LSP
2. Install the extension `Clang Power Tools` in [Visual Studio Community](https://visualstudio.microsoft.com/vs/community/)
3. Open the solution `FFNx.sln` under the `.build` directory with **Visual Studio Community** (**sln** file is generated by the build process)
4. Right-click on **FFNx** solution (under the **Solution Explorer**) then click on **Clang Power Tools** -> **Export Compilation Database**
5. Copy the `compile_commands.json` generated file into the root of the repository
6. Open **Neovim** and enjoy!

To build from the terminal (example with *RelWithDebInfo*):
- For dependency use: `cmake --preset RelWithDebInfo`
- For building the project: `cmake --build --preset RelWithDebInfo`

**NOTE**: Make sure to use the `cmake` executable that comes from Visual Studio
(e.g. `C:\Program Files\Microsoft Visual Studio\2026\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe`)

## Auto-Formatting

### CMake Files

0. **REQUIRED!** Install [Python](https://www.python.org/)
1. Install [cmake-format](https://github.com/cheshirekow/cmake_format#installation) and make sure the binary is available in your PATH environment variable
