A Custom Cartridge Makes YouTube Work on a Game Boy Color
Throaty Mumbo built a custom GBCTube cartridge to play YouTube video on a Game Boy Color's 160×144 display. The project progresses from displaying images and video to streaming over the link cable, then adds custom Wi-Fi-capable hardware.
The video demonstrates playback on real Game Boy Color hardware and covers the cartridge electronics, battery and enclosure built for the project.
There are countless easier ways to watch YouTube, but this one starts by building a Wi-Fi cartridge for a handheld that originally did not even have a backlit screen. The setup is more elaborate than the viewing.
