The alphanumeric strings altered the behavior of the Secret of Evermore game on the Super Nintendo Entertainment System (SNES). These codes, designed for use with a specific accessory, permitted players to modify various aspects of the gameplay experience, such as character attributes, item availability, and other game mechanics. An example includes a code that grants infinite currency within the game world.
The utilization of such codes provided players with increased control over their gaming experience. They could overcome difficult challenges, explore previously inaccessible content, or simply experiment with different game parameters. Historically, these codes offered an early form of game modification and customization before the widespread availability of official patches and mods. They filled a niche need among players seeking a more personalized and, at times, easier gameplay experience.
