How To Make A Gameboy Game

Summary: If you’re a lover of classic games, it can be an exciting experience to make a Gameboy game on your own. Though it takes time and effort, making a Gameboy game can be a thrilling learning opportunity for anyone interested in game development. In this article, we’ll go through some basic steps on how to make a Gameboy game.

1. Understanding the Gameboy hardware

The first step in making a Gameboy game is understanding its hardware. It has an 8-bit processor, and the screen size is 160×144 pixels with a limit of 4 colors per tile. The maximum screen area where graphics can be rendered is 20×18 tiles. The sound hardware can play four-channel sounds at different tones. These limitations might require some adjustments from other software development practices.

Additionally, the Gameboy has a memory limit of around 32K. Therefore, managing memory should be a prominent consideration during programming. Each game requires coding, artwork, and soundtracks, and all these elements must be within that small memory limit.

Once you understand the hardware requirements, you can start programming. Generally, people prefer C or assembly code for programming because they are efficient and give more access to hardware.

2. Setting up the environment

To get started, you need a Gameboy emulator, such as BGB or VisualBoyAdvance. They aid programmers to execute and test programs on a PC before uploading it onto a real Gameboy. Installing software like GBDK (Gameboy Development Kit) and RGBDS (Rednex Gameboy Development System) can help you get started on developments.

You also need an Integrated Development Environment (IDE) to program games. An IDE allows you to edit, test, and build the code. Examples of good IDEs for Gameboy Development are Code::Blocks, Notepad++, or Sublime Text Editor. Using an IDE can enhance your development experience by supporting auto-completion and other convenient features that will save you time.

The final step in setting up your environment is artwork software for creating graphics. You can use open-source image editors like GIMP or paid editors like Photoshop.

3. Writing the game code

To write a game code, you need to focus on the game mechanics. At first, develop a simple game: plot the character movement and develop user inputs (jumping, shooting). Applying a sprite to a pixelated character and designing stage backgrounds is fundamental to produce a compelling gameplay experience. Be sure to optimize the graphics to ensure smooth playing action within the small memory limits of the Gameboy.

Incorporating animation into the game improves its gameplay experience. Consider animating moving platforms, enemies, and background elements. Learn how to incorporate sound effects and music. Because the Gameboy sound system produces specific limitations, sounds must be well-thought-out, and they need to blend in with the game’s atmosphere.

Finally, when it comes time to combine all these components, aiming for the smallest possible Gameboy executable file size is mandatory. A large file may cause a Gameboy to crash. Optimize the code as much as possible.

4. Debugging and Testing

Programming is based heavily on trial and error. To test the game, utilize the Gameboy emulator to locate and fix bugs or errors. Furthermore, using the emulator also allows you to simulate gameplay and find any issues in graphics, audio, and code. Ensure that all directions of the device, including buttons and joysticks, perform adequately before real testing.

Once the testing phase is complete, you should create a release version of the game programmed in your native environment and release it on different emulators like Gameboy emulators or hardware like EverDrive, which offers an SD Card Adapter allowing you to run homebrew games on an actual Gameboy console.

The gamers’ feedback can provide ideas for adding features that a player may feel could improve gameplay.

5. Publishing and Releasing the Game

After completing the previous stages, publishing and releasing your work is the most gratifying part of programming a Gameboy game. Sharing your game on platforms like Github will allow others to access and play your creation.

It is also essential to label your game as a homebrew game unless appropriate licenses are obtained. Giving credits to all contributors, including artwork and music contributors, is mandatory. Check legal requirements to ensure compliance with the issued licenses for Gameboy games legally. You wouldn’t want to encounter legal issues that might prevent you from sharing your game with others.

Remember, dedicate time and effort through initial development through to release. With this, you’re sure to produce an exciting Gameboy game that can provide fun and learning experiences for gamers of all ages.


By creating a Gameboy game, you can transform gaming into development pursuit, offering vast exposure to game creation, gaining knowledge about graphic design and sound production. We hope this guide has assisted you in taking your first steps in developing your Gameboy game so that game enthusiasts can enjoy your design, creativity, and efforts.

Making a Gameboy Game can be an exciting activity, turning the game development world upside down. With this useful guide, you now have an idea of how to develop, debug and release your own Gameboy game. Wish you the best luck in creating your very own Gameboy game and enjoying the process while at it!
