This is a hack of Sonic the Hedgehog for the Sega Genesis. It redesigns many aspects of the original and adds new content. There are various cutscenes that play at various parts of the game. Levels are redesigned: there’s new palettes, some new graphics, new music, new level names. Some new features are available such as respawn points after falling into a pit, rings expelling from enemies, and many other changes the author of the hack wants people to discover on their own.

The patch is in xdelta format. The ROM should be in BIN format.
