Sonic 1 Alt is a layout hack of Sonic the Hedgehog for the Sega Mega Drive by Ell678. It is notable for sporting barely any ASM edits, with the main focus being on the level layouts. 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.
