MAME 0.78 represents a snapshot in time before the project shifted its philosophy. In the early 2000s, MAME was primarily about playability. By version 0.78, the emulator had successfully documented the vast majority of the "Golden Age" of arcade gaming. It includes virtually every major hit from the 70s, 80s, and 90s: Pac-Man, Donkey Kong, Street Fighter II, Mortal Kombat, Galaga, and Robotron .
