How a local video game studio gave Atari its first new cartridge release since 1990

Video games were once synonymous with cartridges. A St. Louis game developer, Graphite Lab, is turning back the clock with its release of “Mr. Run and Jump.” Out on modern consoles from Playstation, Xbox and Nintendo, a version of the game is also being released for the Atari 2600 — and, for the first time since 1990, Atari is releasing the new game on a cartridge. Graphite Lab developer John Mikula reveals how he created “Mr. Run and Jump” as a passion project and what happened after Atari took notice.
