I Play on ipad with a clone called "LEVITAR2", is free, and is nice. Not really the same because it only reproduces one kind of planet (side scroll planet with Y-Axis gravity).
Really is a nice game, and i think one of the few atari vector cabinet you can find at a not very high price (battlezone, lunarlander, starwars, tempest, major havoc....have crazy prices).
Well, all atari vector are beatufull in fact.
