Sonic the Hedgehog - The Lost Worlds is a ROM hack of Sonic the Hedgehog 2 for the Sega Genesis, featuring levels that were cut during development. The game includes recreations of several scrapped zones based on prototypes, concept art, and interviews. Notable levels include Dust Hill Zone, Rock Zone, and Hidden Palace Zone, each enhanced from original concepts.
Despite the hack name, this is a hack of Sonic the Hedgehog 2 for the Sega Genesis and not a hack of Sonic 1. The hack incorporates levels which were scrapped before the game was released. The levels are recreated using information gathered from either prototype ROM releases, scrapped data from the final ROM, information found in interviews, game screenshots, or concept art. Unlike other lost level restoration hacks this hack only incorporates the lost levels and no other levels are included aside from the prototype version of Casino Night Zone.
