History Trivia / SonicTheHedgehogCD

** Most hilarious of all, the "dash zone"'s that are found in Stardust Speedway are translated as "zonas de putos", or "fuck/fucker zone".

** While ''Sonic CD'' itself has since become more accessible thanks to its PC port in 1996 (which was also included in ''[[CompilationRerelease Sonic Gems Collection]]'') and the remastered port by Christian Whitehead in 2011, the original Sega CD version has yet to see an official rerelease on any platform and copies of the original game tend to go up for [[CrackIsCheaper extremely high prices on online stores]]. There were plans to include it in ''Sonic Mega Collection'', however the lack of documentation for the Sega CD led to Creator/SonicTeam cutting it out from the lineup.

* PromotedFanboy: Whitehead, who did the downloadable remake. He was responsible for creating the Retro Sonic engine, a number of fangames, and is also a member of the Sonic Retro community.
* ScrewedByTheLawyers: The vocals for the Japanese soundtrack were replaced with instrumentals for the HD remake due to unforeseen legal issues regarding the rights to them. Fortunately, this doesn't appear to be a problem anymore, as ''Sonic Origins'' adds them back in.

* ChristmasRushed: Spencer Nilsen's sound team was given a meager ''two months'' to compose an almost entirely new soundtrack for the game's American release. They were so pressed for time that they weren't even able to replace the Past songs, due to the more complicated programming involved (i.e., the tracks being directly coded into the game instead of being stored as ordinary CD audio tracks).

* {{Blooper}}: The French portion of the European manual refers Sonic himself as “Sonic the Hedgehog CD” at one point.

** Cut ''segments'' of songs exist, as early prototypes had what appeared to be unused in-game music loop pieces that would apparently inconspicuously play while the CD track ends and re-loads from the beginning. May have been removed due to time or inability to perfect this feature, but it was restored in the 2011 remake.

** Some assume that ''Sonic CD'' was either originally a CD port of ''Sonic 2'' or that both were originally one and the same. However, Naoto Ohshima has stated that ''Sonic CD'' was never meant to be ''Sonic 2'', but rather a CD version of the original ''Sonic the Hedgehog''. He does state that the team behind ''CD'' may have had more fun with creating the game, as they weren't under the pressure of making ''the'' second ''Sonic'' game.

** On May 2022, the 7th generation console ports and Steam version of the game was delisted from their respective platforms in preparation of ''Sonic Origins'', however, the mobile version on Google Play Store and Apple App Store are available.

* ShrugOfGod: Creator/SonicTeam and Creator/{{Sega}} have taken an overall nebulous position on the game's chronological placement and have [[FlipFlopOfGod flip-flopped]] on the position numerous times. One [[https://shmuplations.com/soniccd/ 1993 interview]] implied that the game seemingly takes place between ''VideoGame/SonicTheHedgehog1'' and ''VideoGame/SonicTheHedgehog2'', pointing out the notable absence of both Tails and Super Sonic from the game, though the former ended up making a cameo. This was more clearly [[https://sega-memories.blogspot.com/2011/12/sonic-cds-secret-strategy-guide.html stated]] in Brady's ''Sonic The Hedgehog 3'' Full Color Action strategy guide. A decade later, [[https://sonicretro.org/2011/08/27/sega-staffer-speaks-sonic-cd-details-revised-as-sonic-4-prequel/#more-4520 another interview]] reportedly stated that the game took place after ''VideoGame/Sonic3AndKnuckles'', but before ''VideoGame/SonicTheHedgehog4'', only to [[https://sonicretro.org/2011/08/28/corrections-video-interview-with-ken-balough-on-sonic-cd-sonic-4/ then re-clarify a day later]] that ''CD'' is a standalone adventure that doesn't have a concrete place in the canon, other than it took place sometime before ''Sonic 4''. However, this would flip flop yet again with the ''Sonic Encyclo-speed-ia'', which once again implies that ''CD'' takes place between ''Sonic 1'' and ''Sonic 2''. ''VideoGame/SonicOrigins'' seems to have finally settled this once and for all by having it be between ''1'' and ''2'' on the game selection menu and its story mode, confirming its status as an {{Interquel}}.

* FlipFlopOfGod: Regarding the game's placement in the timeline-- in an October 1993 interview with the magazine ''BEEP Mega Drive'', Special Stage designer Yasushi Yamaguchi (also known for being the lead artist for ''VideoGame/SonicTheHedgehog2'') stated that ''Sonic CD'' [[https://archive.ph/QJTcX "falls in between Sonic 1 and 2 in terms of chronology"]], making it an {{Interquel}} of the first two games. More recently, however, game director Naoto Ohshima has stated that [[https://twitter.com/YinTheAkuma/status/1516795423847075846/photo/3 Metal Sonic is an "evolution"]] of the Mecha Sonic seen in ''Sonic 2'', a sentiment [[https://twitter.com/Mazin__/status/1227808240127205377 repeated by level designer Masato Nishimura]], implying that it must take place sometime after it instead. That being said, Ohshima has also stated in the aforementioned sources that ''CD'' wasn't originally designed with a definite timeline placement in mind, anyways, and ''VideoGame/SonicOrigins'' follows Yamaguchi's claim regarding it taking place before ''Sonic 2''.

* GodNeverSaidThat: Sega had never stated at any point that the ''"CD"'' in the game's title retroactively stands for "''Chrono Distortion"'' as of the 2011 port.

* WordOfGod: Naoto Ohshima has stated that ''Sonic CD'' was never meant to be ''Sonic 2'', but rather a CD version of the original ''Sonic the Hedgehog''.
--->'''Ohshima:''' Sonic CD wasn't Sonic 2; it was really meant to be more of a CD version of the original Sonic. I can't help but wonder, therefore, if we had more fun making CD than they did making Sonic 2 [because we didn't have the pressure of making a "numbered sequel"].

* WhatCouldHaveBeen:

** Naoto Ohshima originally wanted the time travelling to be done in real-time, inspired by ''Film/BackToTheFuture''; however, the programming team deemed this impossible and compromised with the Time Warp loading cutscenes in the final game. Ohshima believed that if Yuji Naka, known for his incredible coding skills, were developing ''CD'' instead of ''Sonic 2'' at the time, it could have been possible.
** Fully-animated cutscenes that acted as transitions between stages were planned, but due to budget reasons, only the intro and both ending cutscenes were animated.
** Originally, there was a ruins level that would have been in between Palmtree Panic and Collision Chaos. However, due to dissatisfaction by the team and it not meeting quality standards, it was cut very early in development with the only traces of the zone left being DummiedOut leftover files discovered when going through the game’s files on a PC (under the name R2, or Round 2), [[http://info.sonicretro.org/images/thumb/1/1d/SCDconcept-R2RainbowWaterfalls.jpg/320px-SCDconcept-R2RainbowWaterfalls.jpg early concept art]], [[http://info.sonicretro.org/images/d/d0/R2Sprites.png leftover enemy and boss sprites]], its [[http://info.sonicretro.org/images/2/23/SCD_R2GIF.gif appearance in the ending sequence]] and one of its tracks, which would be used as the default track in the "D.A Garden" menu.
** The UpdatedRerelease was going to have two brand new levels: "[[ShiftingSandLand Desert Dazzle]]", inspired by Round 2, and "[[TrueFinalBoss Final Fever]]". Time constraints, as well as Creator/SonicTeam [[ExecutiveMeddling feeling that it shouldn't deviate too much from the original game]], resulted in both stages being cut. [[http://i.imgur.com/LxkCq.png?3613 A glimpse of Desert Dazzle]] can be seen by entering "32" and "8" into the respective slots on the Sound Test menu (which, incidentally, also unlocks the level select for Tails), while half finished early attempts of the levels can actually be found in the games via hacking. Whitehead later released a hypothetical [[http://www.tssznews.com/wp-content/uploads/2012/05/Picture-7.png screenshot of Final Fever]] as well as a [[http://forums.sonicretro.org/index.php?showtopic=26302&st=2955&p=686737&#entry686737 description of how the level and boss battle would play out:]]
--->'''Whitehead:''' Yeah, it's colourful since it was intended to be an all Time Stones boss (good future only). Time flows freely, and Eggman's machine is essentially invincible. The idea being Sonic can reach warp speed at any opportunity (instead of getting the warp posts) and must do so to "wind back the clock" to damage the boss. Some parts are running, some areas the screen is locked. I was slightly worried the idea of running to warp might not be self evident (no warp screen, the level and boss would change in real time with some neato effects).
** While Whitehead was still pitching the game's digital port, Simon "Stealth" Thomley[[note]]Known for ''Sonic Megamix'' and his famous ''Sonic 1 GBA'' proof of concept.[[/note]] [[http://www.headcannon.com/hchc/SonicCDDS/ began work on a port for the]] UsefulNotes/NintendoDS, but the project was abandoned once Whitehead's pitch was accepted.
** One of the pieces of concept art for the final boss shows Eggman in a mech suit, though with the panels from the final design still present. This concept eventually became the basis for the final boss of ''VideoGame/SonicMania'', the Phantom Egg.
** On October 26, 2019, a prototype of the game shown off at a Sega World event in 1992 was dumped online. Only Palmtree Panic Zones 1 and 2 are playable, then known as "Salad Plain" (possibly hinting that the rest of the titles would have used food puns rather than {{Alliterative Name}}s). Every other round, including the elusive "Round 2" (notably this is the only known prototype to reference the level, meaning it was scrapped very early on), is listed in the Time Attack menu but is not present on the disc. There were two monitors that were cut from the final version: a Blue Ring monitor which basically acts as invincibility (in later builds, it acted like a triple-layered shield) and a Clock monitor that would stop time. Past themes were also seemingly going to use clearer Red Book audio like the Present and Future themes, instead of the Sega CD's own PCM audio chip. Finally, playing with a second controller would spawn a second, playable Sonic.
** According to [[https://twitter.com/Mazin__/status/1251712173337800705 Masato Nishimura]], Wacky Workbench was originally titled "Crazy Toy Box".
** [[https://mobile.twitter.com/Mazin__/status/1104381096282619904 Also according to Nishimura]], the Metal Sonic projections in the past zones are a leftover from an scrapped idea in which the animals would attack Sonic, due to them mistakenly [[MistakenForAnImposter thinking he was Metal Sonic]].

** ''Sonic the Hedgehog CD'' was reportedly a Sega CD-enhanced port of ''Sonic the Hedgehog 2'', but it was redeveloped as a separate game after ''Sonic 2'' [[GermansLoveDavidHasselhoff flopped in Japan]] (to Creator/YujiNaka's chagrin).

** Within the CD audio tracks of the American version, there's a duplicate of the title theme.
