Sonic - The Lost Land is a hack of Sonic the Hedgehog for the Sega Mega Drive by Shadow Fire. The game is comprised of 7 levels, each filled with traps and badniks intent on bringing down Sonic once and for all. There is also a special realm consisting of 6 Chaos Emeralds. If you have collected at least 50 rings by the time you finish the level, you will see a giant ring. Jump into it to be taken to the secret realm. A dynamic palette system is set up , making each act load its own palette (à la Knuckles' Chaotix), as well as a dynamic music system, allowing each act to load its own music.

Initial response to the new layouts was positive, though the altered palettes were less well received and so have been reverted for the next release.
