The original “400-in-1” cartridge was a masterpiece of misdirection. No pirate cart from the 1990s actually contained 400 unique games; the NES’s technical architecture—with its limited ROM space and lack of a hard drive—made that impossible. Instead, these carts relied on a clever form of redundancy. A single game, like Super Mario Bros., might be listed a dozen times, with minor graphical palette swaps or altered starting levels disguised as “new” adventures (e.g., “Mario 7” or “Crazy Mario”). Others featured “hacked” versions where the player’s character was invincible or the gravity was reversed. The remaining slots were filled with glitchy demos or unplayable duplicates. The promise of “400” was a marketing lie, but it was a lie born of necessity and aspiration. For a child who could only afford one cartridge a year, a multicart offered the illusion of infinite variety—a slot-machine experience of scrolling through a menu of possibility.
