There oughta be a WiFi Game Boy cartridge.
It took a while, but I finally managed to create my own Game Boy cartridge. With WiFi! At this point, it can only demo a simple telnet-style communication and access Wikipedia articles, but I am confident that I will showcase more in the future. For now, the interesting and surprisingly tricky...

Before you waste your time with this article, I should probably make clear what this cartridge can do and, maybe more importantly, what it cannot do. 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 this article, 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 article1, then fetches the “extract” of that article and displays it.
