As Mr. Do stated, Mame does not have this yet. However there is a hacked version of it for the Atari 7800 that is pretty neat. I was just playing it earlier this week. It is spot on as what the description says. I played a round or two, and it was pretty fun.
IMO, There is a much more fun version of a 2 player Pac-Man with both players playing simultaneously that is NEAR arcade perfect. It was made for the Amiga years ago, and truth be told, it was one of the main reasons I sold my Atari ST to get an Amiga. It is called Footman. I looked around on the web, and I can not find a 2 player screenshot, but I can tell you it is FANTASTIC. Instead of Ms. Pac-Man, 1 player is the traditional yellow, and the other is green. The Amiga had stereo sound, and one of the coolest things they did was make each players dot sounds come from separate speakers. It also has other cool features like a maze editor (very easy to use) to create your own mazes, a classic (the version you want) and updated (overhead view), and it holds the top EIGHTY high scores! One down side, is there is a new maze and maze color each round. Fun, but I would like to have control of the maze color. Check it out. You will NOT be disappointed.
