This repository contains several game/multimedia related libraries mostly written in C99/C17 or C++/11.
Core library is the Final Platform Layer (FPL) library that contains various demo applications showcasing its capabilities.
| Name | Description | Platforms | Language | Latest Version | State | Size ~ |
|---|---|---|---|---|---|---|
| final_platform_layer.h | Single file platform abstraction library | Win32/Linux/Unix | C99 | 1.0.0 | Finished | 1500 KB |
| final_dynamic_opengl.h | Single file opengl loader library | Win32/Linux/Unix | C99 | 1.0.0 | Finished | 512 KB |
| final_game_box.h | Single file gameboy DMG/CGB emulator | Independent | C99 | 1.3.0 | Finished | 600 KB |
| final_memory.h | Single file heap memory handling library | Independent | C99 | 1.0.1 | Finished | 24 KB |
| final_xml.h | Single file xml parser library | Independent | C99 | 0.3.1-alpha | Finished | 28 KB |
| final_tiletrace.hpp | Single file tilemap contour tracing library | Independent | C++/11 | 1.02 | Finished | 36 KB |
- All libraries written in C99/C17 are fully C++ compatible.
- Few libraries are still in beta/alpha, even though they are finished.
- Only fully implemented, documented and well tested libraries will leave the alpha/beta phase.

If you want to support any of this library in this repository, you can do this in the following way:
- Compile and test the demos/libraries in several configurations and share your feedback (Platform / Architecture / Compiler / IDE)
- Provide feedback by tickets (features, bugs, improvements, etc).
- Provide new demos to the demos/ folder
- Improve existing demos by pull requests
- Be active in the community, ask questions, help others
- Spread the word / Star the project
You are invited to provide pull quests at any time - helping to improve the libraries and/or demos for me or for others.
However, untested, sloppy generated or poorly designed or broken code will not be accepted!
Code that you provide you must have a certain level of quality:
- Compiles without any errors
- Does not break existing libraries or demos
- Follows the same code style and namings of types, functions, defines, etc.
- Prevents collision of existing functions and types by using prefix and long names
- Good readable documentations of all defines, types and functions
- External library loading and handling supports runtime, static and dynamic linking
- Uses as less memory as possible and focus on data-oriented structures
- Uses existing libraries from root or
demos/additions, whenever possible
Also respect the following rules:
- Prefer
fplMemory*Allocate()/fplMemory*Free()over malloc/free - Use
final_memory.h, when you do lots of memory allocations - Use
final_dynamic_opengl.h, when you need OpenGL functions - Use platform preprocessor guards for platform specific code
- Prefer single translation units over multiple translation units
- Prefer C99/C17 over C++/11
Since 2026, libraries and demos are extensively improved using local and premium AI tools. Every line of code that is/was generated or modified by AI is/was properly reviewed and tested by humans.
Positive examples are:
- PulseAudio backend for
final_platform_layer.h - PipeWire backend for
final_platform_layer.h - Critical audio bugfixes in
demos/additions/final_audio*.h - Fixing seek in
demos/FPL_FFMpeg - Fixing major audio issues in
final_game_box.h - Improving emulation processing in
final_game_box.h - Game Boy Color support in
final_game_box.h
It is allowed to provide AI generated code by pull requests, but those must have a certain level of quality (See section Code Contribution).
You can find more details in the Final Game Tech.
