Games I made a fruit fly Tamagotchi for the Game Boy Advance using a small FlyWire connectome
I’ve been building a GBA homebrew project featuring an anatomical fruit fly model and a small neural circuit extracted from real FlyWire data.
It includes:
- Animated walking, flight, feeding, grooming, and rest.
- A neural activity viewer with 128 neurons and 2,048 connections.
- A Tamagotchi mode: feed, water, play, clean, sleep, and medicine.
- Health, energy, stress, bond, and age, with SRAM saves.
The body comes from the flybody project. Its articulated 3D model is rendered offline into sprites for the GBA. This is a simplified simulation, not a complete fly brain; the extracted circuit gates feeding through MN9.
The latest release addresses SuperCard/SuperFW boot issues.

I’d love feedback on the fly’s appearance and controls—and hardware reports if you try it on a flashcart!
