Sonic 1 Remastered is a hack of Sonic the Hedgehog (16-bit) for the Sega Mega Drive/Genesis by Puto. Unlike most other hacks, the officially released version 1.1 isn't a level art/palette/layout hack as much as an "additional features" hack done in ASM. One of the major additions to the game is added with the choice of using Sonic or Tails throughout the game (selecting a character is done at the title screen). There also exists a version 2 hack which was leaked without Puto's permission, although he later gave permission to upload it onto the wiki.

Sonic Time Of Changes

Sonic: The One Ring is a hack of the original Sonic the Hedgehog game for the Sega Mega Drive / Genesis, created by Mercury. Its defining (and titular) feature is that in each Act, all rings but one have been removed, and Sonic cannot complete the Act without this One Ring in his possession. Thus, in each Act, Sonic must search for the One Ring that will afford him the opportunity to progress. Several alterations have been made to the game, to somewhat balance the lack of rings, and allow backtracking during the search.
