The game was developed during the console’s golden years before being shelved when the 2600 died off.

It took Atari two years to develop the game when the typical time frame was six to nine months. Save Mary was initially created by veteran Atari staffer Tod Frye, behind the 2600 version of Pac-Man and the Swordquest series.

Preordering one of these cartridges for $60 nets you a silver collector’s edition box, a full-colour manual, and the game itself. Only 500 of these carts are available, making them an attractive collector’s item for Atari diehards.

Save Mary requires you to save the title character stuck in a steep canyon rapidly filling with water. You use a crane to build platforms to help her escape the dire predicament. Power-ups appear on the cliffside to help you out.

Atari’s founder Nolan Bushnell praised the title in a 1989 interview, saying it was the “first game in which you rely on construction rather than destruction to save the princess.”

Atari has released several 2600 cartridges, many of which are brand-new titles like Mr. Run and Jump or unreleased “lost” games like Aquaventure. Each cartridge in the Atari XP line is “manufactured to exact standards” with some modern flourishes like beveled edges to prevent pin damage and gold-plated connectors. Atari currently sells an upgraded version of the console called the 2600+, which will run them if you can’t track down an old box.
