A hack based on sonic 3.is not a demo version of anything, it's just a collection of boss ideas I had, which were inspired by games from Konami. Keep in mind that these bosses are still difficult and you'll need to spend time studying their pattern to win.There's Quick Start in the game, which is a feature from Contra Hard Corps. It allows for instant respawning without reloading the level.Credits:Programming: - TheBlad768.Music ports: - FoxConED.Graphics: - Mr.Cat, Dolphman.External Credits:Sonic 2 Clone Driver - Clownacy.

Sonic 3 & Knuckles: Pro Survivor it's an palette and layout hack; the point on this one it's to have a extra difficult and hard layout (though fair), with some improved gimmicks.In the last year, I wasn't very happy with the state of the hack, so this one I decided to give it a better effort and polish everything with my best effort (with new content, of course)!Unfortunately, it's still just a demo and not a full version. So the 5 only levels available are:Angel Island Zone, Hydrocity Zone Act 1, Ice Cap Zone, Flying Battery Zone and Sandopolis Zone (unfortunately too, AIZ and ICZ2 isn't ready yet for Knuckles, so I hope you understand).Also, has a new Main Menu and a New mode (up to you unlock), and in the future will have more features.Now let's go to the credits.CreditsHack Author, Layout and Level Design:*NeoFusionBox Team

Sonic 3D: No Flickies is a hack of Sonic 3D: Flickies' Island made by Sik. The game remains mostly unchanged; however, the Flicky collection system (part of the core gameplay of the original game) has been removed, allowing the player to complete the levels without needing to collect all the flickies in the level to advance. This makes it much more similar to traditional Sonic games, where the goal is to simply make it to the end of the level without dying.This hack was later built upon further in the hack, Super Sonic in Sonic 3D, which was also created by Sik.

Sonic & Knuckles (ソニック&ナックルズ Sonikku to Nakkuruzu?) is a 1994 platform video game in the Sonic the Hedgehog series for the Sega Genesis. It was developed in the United States at Sega Technical Institute by members of Sonic Team, and was published by Sega worldwide on October 18, 1994.In addition to being a standalone game, through a system dubbed "lock-on technology," Sonic & Knuckles acts as an expansion pack to both Sonic the Hedgehog 2 and Sonic the Hedgehog 3, the latter with which it was developed in tandem.

Referred to in-game as Knuckles the Echidna in Sonic the Hedgehog 2, the game is largely identical to Sonic the Hedgehog 2, with the exception that gameplay is altered due to Knuckles having separate abilities from Sonic or Tails. Knuckles can glide and climb walls, allowing him to gain access to areas that had been otherwise hidden or unreachable. Conversely, he cannot jump as high, making some situations, such as certain boss fights, especially the final one, more difficult. In this version of the game, the two player mode has been removed.

Sonic the Hedgehog 3 and Sonic & Knuckles were originally to be released as one game,[4] but due to time and financial constraints, it was later split into two separate games. However, Sonic & Knuckles contained "Lock-on Technology", where the Sonic & Knuckles cartridge would be put in the Sega Genesis system, and then another game could be placed onto the top of the Sonic & Knuckles cartridge itself.[4] When Sonic 3 is used in this manner, it enables the player to play through both games as one, titled in-game as Sonic 3 & Knuckles. This features several additions to the games not available otherwise, such as small alterations to the levels, and being able to play through Sonic 3 levels as Knuckles, or Sonic & Knuckles levels as Tails, and the ability to save progress in all of the game's levels.Additionally, this was the only way to collect Super Emeralds, which are earned by accessing Special Stages in the Sonic & Knuckles levels after collecting all seven Chaos Emeralds from Sonic 3. When all Super Emeralds have been collected, Sonic, Knuckles and Tails can transform into Hyper Sonic, Hyper Knuckles and Super Tails respectively, each with unique abilities.
