Tech Stack

If you're curious to know it, FFNx is made with:

  • C++ code base
  • Latest MSVC available on Visual Studio 2022 Community Edition
  • vcpkg ( as dependency manager )
  • CMake ( as make files )
  • BGFX ( as backend renderer )
  • BIMG ( for custom textures )
  • FFMpeg with H/W Accelleration support
  • VGMStream using FFMpeg as backend (with loop support!)
  • tomlplusplus ( for the configuration management )
  • StackWalker ( for stack traces in the log file )
  • pugixml ( for the Steam XML manifest )
  • md5 ( for the Steam XML manifest )
  • libpng ( for a better and faster PNG texture support )
  • imgui ( to better debug the in-game engine )
  • xxhash ( to extract an hash from palette game textures data known as animated textures )
  • SoLoud ( as the audio engine used to playback audio, music or voice files )
  • openpsf ( as the MINIPSF emulation engine to playback PSX/PS2 music files )
  • Steamworks SDK ( used to support Steam achievements for the Steam edition of games )
  • mimalloc ( mimalloc is a compact general purpose allocator with excellent performance )

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 build you can find the output in this path: .build/bin


Please note:

FFNx will now use vcpkg as a package manager to resolve dependencies. Failing to follow these steps will fail your builds.

  1. Clone the vcpkg project in the root folder of your C: drive ( git clone )
  2. Go inside the C:\vcpkg folder and double click bootstrap-vcpkg.bat
  3. Open a cmd window in C:\vcpkg and run the following command: vcpkg integrate install

Visual Studio

Please note:

By default Visual Studio will pick the x86-Release build configuration, but you can choose any other profile available.

  1. Download the the latest Visual Studio Community installer
  2. Run the installer and import this .vsconfig file in the installer to pick the required components to build this project
  3. Make sure you select the English Language pack in the language list before clicking Install
  4. Once installed, open this repository as a folder in Visual Studio 2022 and click the build button

Visual Studio Code

  1. REQUIRED! Follow up the steps to install Visual Studio, which will also install the MSVC toolchain
  2. Download and install the latest Visual Studio Code release
  3. Install the following extensions:
  4. Open this repository as a folder in Visual Studio code
  5. Choose as build profile in the status bar CMake: [Release] ( or one of the aforementioned profiles )
  6. Click the button on the status bar Build


CMake Files

  1. REQUIRED! Install Python
  2. Install cmake-format and make sure the binary is available in your PATH environment variable
  3. OPTIONAL! Integrate it in your own IDE ( eg. for Visual Studio Code use the relative extension )
