Game Description:
Sonic the Hedgehog 2 is a platforming action video game. Developed by Sonic Team and Sega Technical Institute in 1992, it introduces new mechanics to the series, and the lovable young fox known as Miles "Tails" Prower. The massively successful sequel to the original Sonic the Hedgehog, Sonic 2 stands as the second best-selling Sonic game in history, and is considered by many fans as the best Sonic game.

A 2-D side-scrolling platformer, you control Sonic, a blue-colored hedgehog that runs pretty darn fast across the stages (zones as they are called in the game). Alternatively, the player can also play as Tails, who either functions identical to Sonic. Scattered throughout the zones are golden rings that Sonic can collect, which allows him to not only take damage, but allow access to special stages. The special stage, which is now a pseudo-3D tube, involves collecting a certain amount of rings and avoiding bombs.

Returning from his previous defeat, Dr. Ivo Robotnik plans world domination once again by kidnapping and converting animals into robots, and collecting the seven Chaos Emeralds. Unlike his previous frenzy with Sonic, Robotnik has built the Death Egg, a giant battle station orbiting the Earth, and intends to conquer with it. Sonic (now followed by Miles "Tails" Prower) set off to collect the Chaos Emeralds and defeat Robonik once and for all.
Hack Description:
This is a hack which adds a boss attack which features all the bosses from Sonic the Hedgehog and Sonic the Hedgehog 2 for Genesis. The hack is based on Sonic the Hedgehog 2 for Genesis. The hack takes place in Death Egg zone and the objective is to get a good time and ranking. There are two modes, time attack and survival mode. Time attack mode grants infinite lives and has rings placed in-between battles. Survival mode has only three lives and has no rings whatsoever.

The patch is in xdelta format due to shifted data resulting in IPS patches containing original code. The ROM should be in BIN format.
