A digital fruit-fly brain with 139,255 neurons runs on a Pi 5 to play Pokémon

Enthusiast Leetzerzz is running a full simulation of an adult female fruit fly's brain (FlyWire FAFB v783 reconstruction, 139,255 neurons) on a Raspberry Pi 5 alongside mGBA, streaming its Pokémon playthrough on Twitch. Viewers can stimulate reward and punishment neurons to nudge behavior for 10 minutes; game memory feeds wall and character data to looming-detector neurons.

• All 139,255 FlyWire FAFB v783 neurons simulated on a Raspberry Pi 5 with mGBA
• Game memory feeds left/right drive to LPLC1, LC10 and LPLC4 looming detectors
• Twitch viewers zap reward or punishment neurons, with effects lasting 10 minutes
• No image processing or retinotopy — an acknowledged limitation of the setup
