This week, I'm sharing another of my harebrained hobby projects and show you how it's possible to use the Ext port on a Sega Genesis to communicate with a PC over serial. As well, we'll give a look at my memory-swapping ROM cart that can be used to upload and execute ROM images over serial on-the-fly.
Or at least that's the theory. Stay tuned for the surprise ending
