Ok people!  Here we are, the place where you can download 2 great Atari 2600 Console emulators and some games for those emulators!

The PC Atari Emulator, or PCAE, is an MS-DOS program designed  to
emulate  the  famous  Atari 2600 Video Computer  System  on  PC's
compatible  with  the Intel 80486 CPU or better. It  accomplishes
this with an emulation engine that is written almost entirely  in
assembly language, with extra features written in Borland  Pascal
7.0 for DOS.

System Requirements

OS:       MS-DOS,  though it will run from within a  Windows  DOS
          prompt. Some users have successfully run it from within
          an  OS/2  DOS  prompt by setting the "Allow  access  to
          hardware timer" flag to ON.

CPU:      Intel  80486  or  greater, for  the  BSWAP  instruction
          (though a Pentium is highly recommended for performance
          purposes)

RAM:      540K  free  low DOS memory (though 590K or  greater  is
          strongly recommended). Also, at least 2Mb of XMS memory
          is  needed  to  store sound samples (setting  a  larger
          sound buffer requires more XMS memory)

Other:    A mouse is  required for single-player paddle emulation
          A 4-button joystick is strongly recommended, ESPECIALLY
          a   Gravis   GamePad.   Two  joysticks   are   strongly
          recommended  for two-player games To use  joysticks  to
          emulate  paddles  two and three, analog  joysticks  are
          required.
          A  special home-built board is necessary for connecting
          real Atari controllers to the PC.
 
Sound:    A   SoundBlaster  or  100%  compatible  sound  card  is
          required  for sound support. To get perfect sound  from
          within  a  Windows DOS prompt the sound  card  must  be
          compatible  with Sound Blasters utilizing DSP  versions
          2.00 or greater
