Way back in 2012, Google "released" an 8-bit version of Google Maps as one of the company's then-annual April Fool's Day jokes. There was a low-res 8-bit style of Google Maps to play with, but the company didn't deliver on its promise of a cartridge you could pop in your old Nintendo Entertainment System. However, some nine years later, someone figured out how to pull this off, with the help of a heavily-modified NES system and the previous work of other hackers before him.
