History VideoGame / SonicTheHedgehogMegamix

''Sonic Megamix'' is among one of the longest-standing [[GameMod Game Mods]] for a UsefulNotes/SegaGenesis Sonic title in development, having been around since [[LongRunners 2005]], and still being upgraded further even with public versions of it already out to be played. It has become such an expansive hack that it was ported from a Genesis format to a UsefulNotes/SegaCD format, allowing it to run Redbook Audio music and even play on an actual Sega CD when properly burned to a CD-R.

On the fateful day of 07/02/2016, however, [[http://forums.sonicretro.org/index.php?showtopic=35614 Stealth declared]] ''Sonic Megamix'' as originally envisioned couldn't be worked on any more due to most of the original team having moved on to other matters. He still plans to eventually release what's been done of the project in a presentable fashion and the game's engine as open source.

* UnwinnableByMistake: The most recent version (the tentative 5.0 version) cannot be completed by anyone except Tails (without cheats), as the layout for Starry Night Zone Act 3 is completely broken.

''Sonic the Hedgehog Megamix'' (also known as ''Sonic Megamix'') is a [[GameMod ROM hack]] of the original ''VideoGame/{{Sonic the Hedgehog|1}}'' game by Team Megamix, led by Simon "Stealth" Thomley. It takes the original game and gives it an extreme overhaul, including new level layouts and graphics, new moves for Sonic that he gets in future games, and 4 more characters besides himself (Tails, Knuckles, [[VideoGame/KnucklesChaotix Mighty]] and even [[CallForward Shadow]]), each of them having their own abilities and [[SuperMode Super Modes]], as well.

Stealth, himself, has released [[https://www.youtube.com/watch?v=mZFJT-0kVlQ a trailer]] that contains even further updates to the game, and letting us know right in the trailer's title that the game is [[{{Vaporware}} Never Cancelled]]. He has also posted [[http://hcstealth.tumblr.com/post/123576317307/sonic-megamix-tech-tease a tech article]] on the current state of the game, and promised that if he gets enough donations through [[https://www.patreon.com/HCStealth his Pateron page]], he'll look into creating a stable version of Version ''4.0b'', which he dubs ''Sonic 1 Megamix'' as the game changed so much since then it was essentially no longer ''Sonic 1''.

* UnderTheSea: Misty Maze Zone, the hack's update to Labyrinth Zone. It replaces Labyrinth's UnderwaterRuins setting with Atlantis-esque seascape from one of ''VideoGame/SonicTheHedgehogCD''[='=]s Special Stages.

* ShoutOut: Several. Because this hack is based on the first game, many moves, items, graphics and even music have appeared from later Sonic games and other games such as ''VideoGame/{{Columns}} 3'' and ''VideoGame/{{Ristar}}''. Even sound effects are ported from other games, such as the title screen confirm sound being ''VideoGame/GunstarHeroes''[='=]s own, the LargeHamAnnouncer from ''VideoGame/StreetFighterAlpha 3'' calling the start and end of boss fights, and even tracks from ''[[CompilationRerelease Mega Man: The Wily Wars]]'' (particularly the Password theme and the famous Wily Stage 1 theme from ''VideoGame/MegaMan2''.

* PaletteSwap: The earlier builds of the game show that the new zones started out as palette swaps of the original ''Sonic 1'' zones. As newer versions get released, more zones end up getting complete makeovers that goes above and beyond this trope. See ArtEvolution above for an example.

* UnderTheSea: Misty Maze Zone, the hack's update to Labyrinth Zone.

** Speaking of Super Sonic, he can also jump dash in any direction the player holds if he isn't near an enemy, just like [[InfinityPlusOneSword Hyper Sonic]] in ''VideoGame/Sonic3AndKnuckles'', and with an S-Monitor, he can fly in a straight path similar to how he could be used in the TrueFinalBoss of that game. Hyper Transformations outright make a return in the leaked "5.0" version via a secret code.

* {{Flight}}: One can control Tails' flight just like in ''VideoGame/Sonic3AndKnuckles''. Super Sonic can also achieve this after breaking open an S-monitor.
* LuckilyMyShieldWillProtectMe: Mighty uses Sonic's moveset from ''VideoGame/Sonic3AndKnuckles'', right down to being able to use Sonic's Insta-Shield and his jump moves of that game's elemental shields. New to this game is Mighty's ability to store up to 4 shields and being able to switch between them on the fly to take advantage of the different immunities and attacks each of them have (the one exception being Sonic 1's which has no additional abilities).

* SuperMode: All 5 characters have one, and can use it after getting 6 Chaos Emeralds instead of 7, since ''Sonic 1'' only had 6 emeralds (though according to the [[http://www.teammegamix.com/index.php?p=mm_story story]], Eggman brought the seventh one along with him). This game allows you to change back to normal in order to conserve rings.
