ISS Real-Time Tracker
This NES ROM is an International Space Station tracker. ISS location data is sent to the console over the controller ports and displayed on the screen.
I wrote a blog post titled "International Space Station Tracker for the NES" that goes into more details about this project.

The project was also written about in a VICE article titled "Hack Lets You Track the International Space Station With an NES" written by Patrick Klepek

The source code was written back when I was grabbing and serving ISS tracking data from a NASA web page that is no longer available, so it will not be trivial to get this project running. I recommend looking into my Sattrak project instead. Either way, the ISS Real-Time Tracker ROM and source code are linked below.
