Sonic the Hedgehog - The Lost Worlds

Hack of Sonic the Hedgehog 2

Description:

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.

Levels

  • Dust Hill Zone: Based off the single mock-up image found in magazines.
  • Rock Zone: Based off info found in a piece of concept art.
  • Wood Zone: Based off the design found in a prototype.
  • Winter Zone: Based off info from an interview. Includes Christmas trees.
  • Hidden Palace Zone: Based off design found in a prototype. Uses the intended music found in the final version of the game.
  • Casino Night Zone: Based off the design found in a prototype. Uses the music found in the prototype.
  • Cyber City Zone: Based off a piece of concept art.

ROM / ISO Information:

  • No-Intro Name: Sonic The Hedgehog 2 (World) (Rev A)
  • ROM/File SHA-1: 8BCA5DCEF1AF3E00098666FD892DC1C2A76333F9
