The Nintendo Game Boy had long been a symbol of success for the Japanese gaming company for many, many years, and it goes without saying that many of us who grew up in the 1990s had our fair share of fond memories of the Game Boy.

Of course, this is not to say that there has been no Game Boy emulators running on mobile devices thus far, but those have tended to be unofficial emulators.
