Entering the world of game development can feel a bit like stepping into a fantastical arcade filled with endless possibilities. If you’re excited to explore the Nintendo Learning Environment, this guide will lead you through the essentials to kick-start your game-building journey!

Step 1: Build the C Library

Before you can dive into the games, you need to build the Game Boy shared library. This library contains the necessary tools to interact with your game files.

make gameboy.so

Step 2: Run the Front End via Python

With the library successfully built, you can now run the virtual Game Boy using a Python script. This will allow you to interact with ROM files seamlessly.

python gameboy.py --rom PATH_TO_ROM

C and Python Dependencies

• No C dependencies required.
• Python dependencies: Numpy, CFFI

Troubleshooting: Gameboy.so Not Found

If you encounter an issue where gameboy.so cannot be found, a simple fix is to set the library path in your terminal:

export LD_LIBRARY_PATH=.

This command tells your operating system to look in the current directory for the library file.

Usage: Example Command

To see your games in action, you can run the provided Python wrapper, generating GIFs while you play!

python gameboy.py --rom .gb_roms/Micro_Machines_(USA,_Europe).gb --framelimit=500000 --write_gif_every 30 --write_gif_duration 50

This command runs the environment for 0.5M steps and produces a GIF every 30 seconds. The results will look something like this:

Output:

time: 00h 00m 30s, frames 0.06M
time: 00h 01m 00s, frames 0.12M
time: 00h 01m 30s, frames 0.18M
time: 00h 02m 00s, frames 0.24M
time: 00h 02m 30s, frames 0.30M
time: 00h 03m 00s, frames 0.36M
time: 00h 03m 30s, frames 0.42M
time: 00h 04m 00s, frames 0.48M

GIF Generation

Every 30 seconds, you can generate GIFs of your gameplay, making it easy to share your gaming highlights!

Here is an example of GIFs generated from your ROM:

Advanced Usage: Creating GIFs and NPY Files

If you’re looking to generate numerous frames and save them as GIFs or NPY files, use the following command:

python make_gifs.py --rom PATH_TO_ROM

By running something like:

python make_gifs.py --rom .wario_walking.gb

You will get a file like this:

Standalone Game Boy with GLFW Support

If you prefer a more hands-on approach, you can also build a standalone version of the Game Boy with GLFW support:

make

To play, enter the following command in the terminal:

.gameboy PATH_TO_ROM

Control the game with the following keys:

• Enter – START
• Space – SELECT
• Z – A
• X – B
• + Arrows – directional controls (Left, Right, Down, Up)
• SHIFT – turbo mode

Conclusion

With these steps, you’re ready to unleash your creativity and start making your own games with the Nintendo Learning Environment. Don’t forget to share your projects and enjoy the journey!
