      MAME's purpose is to preserve decades of software history. As electronic
      technology continues to rush forward, MAME prevents this important
      "vintage" software from being lost and forgotten. This is achieved by
      documenting the hardware and how it functions. The source code to MAME
      serves as this documentation. The fact that the software is usable serves
      primarily to validate the accuracy of the documentation (how else can you
      prove that you have recreated the hardware faithfully?). Over time, MAME
      (originally stood for Multiple Arcade Machine Emulator) absorbed the
      sister-project MESS (Multi Emulator Super System), so MAME now documents a
      wide variety of (mostly vintage) computers, video game consoles and
      calculators, in addition to the arcade video games that were its initial
      focus.
