Random #SuperMarioBros3 #NES memory. Because the game didn't have a battery to save, you had to leave it running between sessions if you didn't want to lose progress.
I remember leaving my console to get dinner one time and for the entire duration of the meal I could hear this in the distance... (why-oh-why didn't I turn off the TV? lol!):
@peejay hearing this music is when you knew you had a good run going
