This hack started as a small joke hack, just to see if I could add something we all love to classic Sonic games; micro-transactions. This was more or less a success, although not as I imagined it. Nevertheless, I found myself just adding more and more random bits for substance, and eventually even found myself playing around with something completely foreign to me on the side. This led me to have an idea for a bossfight, and as such GHZ2 boss was born! And by that, I got an idea; What if I make full hack with new boss fights! And since then I've been pretty much adding anything to my mind comes up with, as well ass lots of bosses.But, what is this hack? Well, I dont know to be honest. It was at one point a joke, then a real hack... And then a joke again? I lost track by now. What I do know, is that none of this makes sense, especially the secrets... err, features in this hack. I would especially like to help following people for their major contributions to making this hack be as good (or bad :V) as it is:Vladikcomper: Sound Driver, Mega PCM, lots of cool music, and help with sound driver issues.djohe: Bug testing, Quality assurance, and help with solving some issues.Ducks: Bug testing, Quality assurance, and lots of neat ideas.Jorge: A lot of help with hardware information and Natsumi screen help.Other people who helped:Betatesting: Vladikcomper, Sonicvaan, TheStoneBanana, MarkeyJester, Animemaster, DA.

Syndicate Wars, or SW for short, is a groundbreaking hack developed by Red Crimson with help from gsaurus and Daors. It allows you to play with any character of the game, including bosses and thugs, PLUS Adam Hunter (Original Sprites by Daors). That's 23 playable characters! No enemy characters are modified, they play as they are in the original. All characters are selectable on the select screen.Syndicate Wars is designed to be fully moddable with the Pancake2 Editor (v1.6 and above, see further below).

Super Sonic in Sonic 3D is a hack of Sonic 3D: Flickies' Island made by Sik. This hack allows the player to turn into Super Sonic in said game after collecting all sevenChaos Emeralds, mimicking its prequels Sonic 2, Sonic 3 and Sonic & Knuckles. The rules are borrowed from the latter two games, so the player must double jump to transform and also must not have a shield in that moment, besides the basic requirements (having all emeralds and 50 rings).All of Super Sonic's behaviour is implemented: a custom palette, a transformation pose with a fading palette, invincibility (with stars), speed shoes and a music change upon transformation. Rings drain while transformed as well. Super Sonic can still be killed by getting crushed by some falling platforms, however, so he isn't completely immune to death.This hack is based off Sonic 3D: No Flickies, and as such it shares the same gameplay rules.

The S Factor: Sonia and Silver is an in-progress multi-level hack created by Aquaslash of Sonic the Hedgehog on the Sega Mega Drive/Genesis. The game allows players to choose between two characters, Sonia, and Silver, and offers several moves attributed to those characters.
