You can find a very handy list of all audio and other games at http://www.pcsgames.net/ Who also sell the packman talks game mentioned earlier, http://www.draconisentertainment.com/ also sell a very addictive packman style game called dynaman wich even gives you the ability to create your own mazes to play in rather than having one standard level as in traditional packman. they also sell a very good space invaders style game, Alien outback, though in that genre I'd also recommend judgement day from http://www.l-works.net/linfo.php
who also have a free remake of the classic duckhunt game.
Then, Usa games are just releasing a great remake of a classic platformer from te 80's, montizumas return (originally Montizumas revenge), which you can find at http://www.usagames.us.
there are also many audio games that while not specific remakes of classic arcade titles, very much follow the same sort of style of gameplay, so I'd deffinately advise checking the Pcs games list and trying a lot of things out. Some of the best arcade style games Imho have been produced by lighttech interactive at http://www.lighttechinteractive.com/webpage/index.php they are also free, which helps.
Finally, My personal favourite racing game is Railracer from blind adrenaline found at http://www.blindadrenaline.com/ Though it's sort of got a futuristic theme, the control and racing style is really involved, and there are also options for things like online play (even entire online tournaments), or creating your own tracks. It does take a litle getting used to, but imho it's well worth it.
I hope with these, and with the above recommendations you can find some of the stuff your looking for.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
