Beyond the technical, the FBNeo complete ROMset serves a crucial role in cultural preservation. The physical cabinets and circuit boards of the 1980s and 90s are succumbing to "bit rot"—the gradual degradation of data stored on silicon chips. As these original boards die, the games they hold are lost forever unless they have been preserved in a digital format. FBNeo acts as the vault for this heritage. By maintaining a complete set, archivists ensure that rare titles that never received home console ports—such as unique beat 'em ups or vertical shooters (shmups)—are not erased from history. It captures the ecosystem of the arcade in its entirety, preserving not just the hits, but the commercial failures and regional oddities that defined the era.
