A WiFi Game Boy cartridge #Nintendo #GameBoy @diconx

Sebastian Staacks tackles a rather thorny problem of configuring the circuitry needed to add WiFi to a Game Boy. It sounds easy, but others had failed before.

This is a basic 32kiB Game Boy cartridge with an ESP8266 microcontroller to add WiFi capabilities. With this, you can access data from the internet or your local network on your Game Boy or send data from it. Since the ESP8266 can do a lot of preprocessing for the Game Boy, a Twitter client is just as conceivable as a Reddit browser. If you implement one. This is not a generic browser, but you can relatively easily implement services on the ESP8266 and write simple code that is executed on the Game Boy as an interface.

At the time of writing, I have only implemented two demos: A simple communication demo that allows you to log onto the cartridge via telnet and send and receive text messages. And a Wikipedia client, which allows you to enter the title of an article, then fetches the “extract” of that article and displays it.
