This version is an unlicensed (Unl) variant of Tengen's Pac-Man, suggesting it was made without official licensing from Namco. Unlicensed games frequently had different graphics, sounds, and potentially gameplay modifications compared to officially licensed versions. This could range from minor differences to major changes. The 'Unl' designation denotes a murky area of the NES game market, showcasing the widespread practice of unlicensed game creation.
