Sonic the Hedgehog 2: Sonic 2 Long Version

This is a hack which adds levels that were scrapped from Sonic the Hedgehog 2 for Sega Genesis. The levels in the hack are listed below:

*Emerald Hill Zone
*Chemical Plant Zone
*Aquatic Ruin Zone
*Casino Night Zone
*Hill Top Zone
*Wood Zone: (scrapped from final release)
*Dust Hill Zone: This version switches between both desert and winter settings. It's probably meant to be a fusion of Dust Hill Zone and the Winter level. (scrapped from final release)
*Oil Ocean Zone
*Genocide City Zone: Original graphics. (scrapped from final release)
*Hidden Palace Zone: (scrapped from final release)
*Metropolis Zone
*Sky Chase Zone
*Wing Fortress Zone
*Death Egg Zone: (original level)

The archive contains two patches, one for Sonic and Tails, and one for Knuckles as playable characters.

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

Sonic 2 Long Version is a more complete version of Sonic 2, which makes it somewhat similar to Sonic 2 Delta. This hack features four levels originally scrapped during Sonic 2's development. Few levels have been changed, four are added. This hack was written in hex, without the aid of any special hacking programs, because the creator uses a Mac, and no hacking tools had been released on that platform at the time of development.

==Levels==
In order according to the level select menu, Sonic 2 Long Version's levels include:

*Emerald Hill Zone
*Chemical Plant Zone
*Aquatic Ruin Zone
*Casino Night Zone
*Hill Top Zone
*Wood Zone: The graphics are similar to what is seen in the Simon Wai prototype. It uses different background music (2 player Emerald Hill Zone). The boss is the same as Aquatic Ruin Zone's boss, but the stone columns are replaced with wooden totem poles and an extra pit has been added.
*Mystic Cave Zone
*Dust Hill Zone: Uses graphics similar to the mockup screenshot of Dust Hill Zone which was featured in many magazines. This version switches between both desert and winter settings. It's probably meant to be a fusion of Dust Hill Zone and the Winter level. The BGM used is from 2 player Mystic Cave Zone. The Emerald Hill Zone boss is reused for this level with no alterations, other than the animal ribs on the ground which act as spikes.
*Oil Ocean Zone
*Genocide City Zone: The graphics used are completely original to a Sonic game. The level has a night time setting with water on the bottom to replicate an underground city sewer. The BGM is different than what was on the Nick Arcade prototype (it is in fact the 2 player Casino Night Zone). This level is actually only one act repeated twice, with a boss at the end of Act 2. The Chemical Plant Zone boss is reused with no alterations made to him.
*Hidden Palace Zone: The graphics and layout are the same as those found in the Nick Arcade prototype. The BGM used is the same that was used in the Final version of Sonic 2. The Mystic Cave Zone boss is reused with no alterations made.
*Metropolis Zone
*Sky Chase Zone
*Wing Fortress Zone
*Death Egg Zone: Act 1 and Act 2 use the exact level layout and graphics from Chemical Plant Zone, but with a space background. Act 3 is Act 1 of the released version.
