     NAME
          2600 - emulator

     SYNOPSIS
          games/2600 [ -a ] [ -x scale ] romfile

     DESCRIPTION
          2600 is an emulator for the Atari 2600.  It executes the
          romfile given as an argument, and controls as if using a
          regular 4-direction 1-button joystick, using space button
          and directional keys.  The q, w, e and r keys correspond
          respectively to the reset, select, player 1 difficulty and
          color mode switches.  Other keys:

          F1   Pause the emulator. If already paused it will step one
               video frame.

          F12  Toggle the emulator's speedometer.  It shows in the
               upper left, off-viewport corner, the ratio between the
               expected and observed time it took to draw 60 frames.

          t    Toggle tracing of the emulator.

          `    It uncaps the 60fps frame rate and lets emulation go as
               fast as possible.

          Esc  Pause the emulator.

          Del  Exit the emulator.

          Command line options:

          -a   Enable audio output.

          -x   Scale the screen to a given factor regardless of the
               window's size.

          A joystick may be used to play the emulator via joy(1).
