Unused voice clips
In the game, each character would mention the team formation that is needed to be in control at different points. However, in the game files, some voice clips indicate that they were going to mention the formation by calling out the teammates' original names.
Unused Eggman/Neo Metal Sonic's quotes
- "Try coming back in about a million ye—"
- "Team Sonic? You must be joking!"
- "Without me, Team Dark is nothing but a bunch of buffoons!"
- "Rragh! This is no place for little girls or a big fat cat!"
- "You call yourselves "detectives"? Just run along now."
Note: The full transcript for the first line is actually "Try coming back in about a million years, then you might have a chance!" The line gets cut off at "Years".
Final Fortress' lasers
In the game files, there are comments explaining how the lasers work in Final Fortress. These quotes state that the colored lasers fire along the rail of the same color, even though all rails are in the same color. In addition, there are comments about the rails lightning up.
|sky02_h03_sn||Sonic||There are 3 colors of lasers: red, blue, and yellow. Each laser fires at the same rail color!|
|sky02_h03_tl||Tails||Hey guys! There's 3 colors of lasers: red, blue, and yellow. Each laser fires at the rail of the same color!|
|sky02_h03_kn||Knuckles||There are 3 laser colors. Red, blue, and yellow. The color of the laser being fired matches the same color rail!|
|sky02_h03_sd||Shadow||There are 3 laser colors. Red, blue, and yellow. Each laser fires at the same color rail!|
|sky02_h03_rg||Rouge||Hey guys! There are 3 colors of lasers: red, blue, and yellow. Each laser fires at the rail of the same color!|
|sky02_h03_om||Omega||Three laser colors of red, blue, and yellow are detected. Each laser color corresponds to a rail color.|
|sky02_h03_es||Espio||There are 3 colored lasers. Red, blue, and yellow. Each laser fires at the rail of the same color!|
|sky02_h03_ch||Charmy||Hey guys! Did you see red, blue, and yellow lasers? There's three colors of rails too!|
|sky02_h03_vc||Vector||It seems there are 3 laser colors. Red, blue, and yellow. The color of the laser being fired matches the same color rail!|
|sky02_h04_sn||Sonic||The cannon lights up right before it fires. Look at the color of the light and make sure to stay off the same colored rail!|
|sky02_h04_tl||Tails||The cannon lights up briefly before it fires! Look at the color, then make sure to stay off the same colored rail.|
|sky02_h04_kn||Knuckles||The cannon will light up right before it fires! Stay off the rail with the same color or you'll get burned by the laser|
|sky02_h04_sd||Shadow||The cannon lights up for a split second before it fires. Make sure to stay off the same colored rail.|
|sky02_h04_rg||Rouge||The cannon will light up right before it fires! Stay off the rail with the same color or you'll get burned by the laser.|
|sky02_h04_om||Omega||Analyze light emission before the cannon fires. Stay clear of the same colored rail.|
|sky02_h04_es||Espio||This weapon illuminates right before it fires! Look at the color of the light and stay clear of the same colored rail!|
|sky02_h04_ch||Charmy||The cannon flashes before it fires. Stay off the same colored rail.|
|sky02_h04_vc||Vector||See the light from the cannon as it prepares to fire? Stay away from the same colored rail or you'll get tagged by the laser!|
|sky02_h08_sn||Sonic||The rail will lights up right before the laser fires.|
|sky02_h08_tl||Tails||The rail lights up right before the laser fires.|
|sky02_h08_kn||Knuckles||The rail we're on now will light up right before the laser fires.|
|sky02_h08_sd||Shadow||The rail will light up right before the laser fires.|
|sky02_h08_rg||Rouge||The rail lights up right before the laser fires!|
|sky02_h08_om||Omega||The rail lights up as a reaction to the laser right before it fires.|
|sky02_h08_es||Espio||Did you notice that the rail lights up before the laser fires?|
|sky02_h08_ch||Charmy||The rails light up for some reason. Maybe it's because of that laser?|
|sky02_h08_vc||Vector||Looks like the rail lights up right before the laser fires.|
Two unused Japanese voice clips for Shadow can be found in the English voice files:
- "That hedgehog..."
- "Is that so... If that's the case, you have no other choice but to die!"
Weights and Klagens
Every character that is caught under a Weight will say something to describe what they feel when getting slapped by this gimmick. However, the lines they say are different from some written in the game files. This difference also goes when caught by Klagens, but they have lines of when they get teleported from the Golden Klagens.
|all04_e04_sn||Sonic||Let me go! I said let me go!|
|all04_e04_tl||Tails||I can't move!|
|all04_e04_kn||Knuckles||I've been captured!|
|all04_e04_rg||Rouge||Hey, let me go you creep!|
|all04_e04_om||Omega||Mobility malfunction! Mobility malfunction!|
|all04_e04_am||Amy||No! Let me go!|
|all04_e04_cr||Cream||Please let me go!|
|all04_e04_bg||Big||Hey! Let go of me!|
|all04_e04_ch||Charmy||Better let go 'a me!|
|all04_e04_vc||Vector||Release me, I said!|
|all04_e07_sn||Sonic||Hey, where are you taking me?|
|all04_e07_kn||Knuckles||Hey, I need help!|
|all04_e07_sd||Shadow||You're gonna pay for this!|
|all04_e07_rg||Rouge||Hey, what're you doing! Help me!|
|all04_e07_om||Omega||Escape impossible! Requesting rescue!|
|all04_e07_am||Amy||I'm being taken away!|
|all04_e07_cr||Cream||I'm being abducted!|
|all04_e07_bg||Big||Let me out of here!|
|all04_e07_es||Espio||This isn't looking good!|
|all04_e07_ch||Charmy||It's no use! I need help!|
|all04_e07_vc||Vector||Hey, isn't anyone gonna help me?|
|all03_e01_sn||Sonic||Yow! This is heavy!|
|all03_e01_tl||Tails||Eh! H-Help me!|
|all03_e01_kn||Knuckles||Get this thing off me!|
|all03_e01_sd||Shadow||Tugh! This is heavy!|
|all03_e01_rg||Rouge||Don't just stand there! Help me!|
|all03_e01_om||Omega||Unable to move! Request assistance!|
|all03_e01_am||Amy||Ouch! This is heavy!|
|all03_e01_cr||Cream||This is really heavy! Please help me!|
|all03_e01_ch||Charmy||This is too heavy!|
|all03_e01_vc||Vector||I can't move!|
When a character is unavailable, they will be waiting inside a checkpoint. However, they are silent in the final game.
|all03_e00_sn||Sonic||Hey, what took you so long?|
|all03_e00_tl||Tails||Phew! I thought I lost you.|
|all03_e00_kn||Knuckles||Where you guys been?|
|all03_e00_sd||Shadow||Hm. You finally made it.|
|all03_e00_rg||Rouge||Sorry I got so far ahead of you.|
|all03_e00_om||Omega||I didn't expect you to make it this far.|
|all03_e00_am||Amy||It's about time!|
|all03_e00_cr||Cream||Sorry for being so late.|
|all03_e00_bg||Big||Where'd you all go?|
|all03_e00_es||Espio||Area checked and secured.|
|all03_e00_ch||Charmy||Hey... Where'd you go?|
|all03_e00_vc||Vector||Sorry, heh. I, uh, got kinda lost.|
In the game files, there are hidden lines about a gate that belongs to Omochao.
|all03_h06_sn||Sonic||Looks like that Omochao has something to do with this gate.|
|all03_h06_tl||Tails||There's an Omochao symbol on this gate. Maybe we should ask that Omochao.|
|all03_h06_kn||Knuckles||Looks like that Omochao has something to do with this gate.|
|all03_h06_sd||Shadow||It looks like that Omochao has something to do with this gate.|
|all03_h06_rg||Rouge||I don't think I can open this door! What's the meaning of that symbol on the gate?|
|all03_h06_om||Omega||Omochao is the guardian of this gate.|
|all03_h06_am||Amy||It looks like that Omochao has something to do with this gate.|
|all03_h06_cr||Cream||It looks like we have to ask Mr. Omochao to help us out!|
|all03_h06_bg||Big||I think that Omochao has something to do with this gate!|
|all03_h06_es||Espio||Looks like that Omochao has something to do with this gate.|
|all03_h06_ch||Charmy||Wow! A gate with the symbol of Omochao! How cool!|
|all03_h06_vc||Vector||Looks like a key won't open this gate. Maybe that Chao has something to do with it.|
In Battle, each opposing team can use Team Blast without any specific time limits. However, in the game files, each team seem to know when their opponents will use their Team Blast, and will order their teammates to take down one of the opponents to stop the move. This is rather pointless, as it will not prevent the Team Blast.
|bos05_h00_sn||Sonic||They will attack with Team Blast if all 3 of them come together! Take out at least one of them!|
|bos05_h00_tl||Tails||They'll attack with Team Blast when all 3 of them come together! We better take down at least one of them and fast!|
|bos05_h00_kn||Knuckles||Those guys will attack with Team Blast if all 3 of them get together! Get at least one of them!|
|bos05_h00_sd||Shadow||They'll use Team Blast if all 3 of them get together! Hurry and destroy at least one of them.|
|bos05_h00_rg||Rouge||They'll attack with Team Blast when all 3 of them get together! We must hurry and take down at least one of them.|
|bos05_h00_om||Omega||They will attack with Team Blast if all 3 of them get together! Eliminate one of them first.|
|bos05_h00_am||Amy||Those guys will attack with Team Blast if all 3 of them get together! Get at least one of them!|
|bos05_h00_cr||Cream||They'll attack with Team Blast if all 3 of them get together! We have to take down one of them quickly.|
|bos05_h00_bg||Big||They'll attack with Team Blast if all 3 of them get together! We have to take down one of them fast.|
|bos05_h00_es||Espio||They'll attack with Team Blast if all 3 of them get together! Best approach is to take down one of them as soon as possible.|
|bos05_h00_ch||Charmy||Those guys will attack with Team Blast if all 3 of them get together! Get at least one of them!|
|bos05_h00_vc||Vector||They'll attack with Team Blast if all 3 of them get together! We have to take one of them down and fast.|
In the game files, there are also unused quotes for all the characters, beside the Speed Type characters, that describe what they feel about the battle.
Invisible Metal Sonic
- Knuckles: Where'd he go?
- Sonic: He's gone!
- Tails: Watch out everybody!
- Espio: Even when he's invisible, he'll briefly appear when he attacks! Pay close attention so you can locate his position!
Team Chaotix and Team Rose's Stages
Both Team Rose and Team Chaotix use shortened/modified versions of Team Sonic's and Team Dark's Stages. However, within the game's files, one can find several lines said by both teams which are referencing areas within the Stages that are not accessible by normal means. Interestingly enough though the aforementioned lines are actually still left implemented into the gameplay and can still be discovered through glitches/exploits that allow the player to reach these further sections of the Stages where they are located.
Team Rose and Team Chaotix's Team Blasts
Team Rose and Team Chaotix explain how their Team Blasts work. The only point in the game in which this is said is on the final whale island in Seaside Hill, which is not a part of the stage for these two teams.
|all02_h16_am||Amy||Team Blast, "Flower Festival," is activated if the Z/R1/White Button is pressed when the gauge in the top right of the screen is full. Once activated, you will be invincible as long as you have energy in the gauge.|
|all02_h16_cr||Cream||Press the Z/R1/White Button when the gauge in the top right corner of the screen is full to activate Team Blast, "Flower Festival." Once activated, you are invincible until the gauge is empty.|
|all02_h16_bg||Big||To activate Team Blast, "Flower Festival," press the Z/R1/White Button when the gauge in the top right corner of the screen is full. Once activated, you are invincible until the gauge is empty.|
|all02_h16_ep||Espio||Press the Z/R1/White Button when the gauge in the top right corner of the screen is full to activate the Team Blast, "Chaotix Recital." Once activated, defeated enemies are transformed into Rings until the gauge is empty.|
|all02_h16_ch||Charmy||Team Blast, "Chaotix Recital," is activated when the Z/R1/White Button is pressed while the gauge in the top right corner of the screen is full. Bad enemies are turned into Rings until the gauge is empty.|
|all02_h16_vc||Vector||Press the Z/R1/White Button when the gauge in the top right corner of the screen is full to activate Team Blast, "Chaotix Recital." When activated, the defeated enemies turn into Rings until the gauge is empty.|
Note: "Flower Festival" explains only Invincibility and doesn't explain anything about the power cores. Along with that, the Invincibility lasts, like the normal Invincibility time, in the Final game. However, according to these clips, the Invincibility would've had a time limit, having the power up until the gauge is empty, which was changed in the final game.
Chaotix' Lava Room
Team Chaotix' Power Plant ends before the rising lava room, but there are voice clips recorded for when the lava rises. Although it's possible to get in via glitching, it only has a spring, a grate, the final vertical door...and nothing else. The voice clips don't even trigger.
|cty02_e01_ch||Charmy||Whoa! Looks like that lava is rising!|
|cty02_e01_es||Espio||Hmm! Watch out everybody!|
|cty02_e01_vc||Vector||Must be an energy storage tank. Better get out before it gets full.|
Charmy goes alone
There are some clips that indicate that there was supposed to be sections in Rail Canyon where Charmy has to leave his teammates behind:
- "If they can't come over here, then I guess I'm on my own!"
- "Wonder if that switch did anything? Maybe I should check!"
Team Rose's unused lines
Team Rose is the only team in Sonic Heroes without chase parts, so some comments go unused.
- Big: Something big is rolling.
- Cream: It's a giant rock!
- Amy: Aahh! Run!
- Cream: Another rock is chasing us!
- Amy: No wonder Sonic doesn't like being chased!
- Amy: Three rocks?!
- Big: One, two...
- Cream: Three comes after one and two, Mr. Big.
- Big: I'm feeling toasty.
- Cream: Why is there lava in a city?
- Amy: It's an energy storage tank! Let's get out of here before it rises to the top!
- Big: What's that?
- Cream: It's an alligator. Alligators are reptiles, Mr. Big.
- Amy: Why are you so calm when that thing is chasing us?! We have got to lose it!
There are some comments that Team Rose were meant to say after being shot out of the second cannon in Bullet Station. However, that part does not belong in the final game. To top it all off, Amy's voice clip is empty.
- Amy: Phew, that was something else.
- Cream: Yes, it was.
- Big: Wow, that was scary.
Team Rose's Casino Park ends before the V.I.P. room area, but there are still lines recorded for it. These lines can be heard by utilizing glitches to access the area.
- Amy: So this is the V.I.P. room, huh?
- Big: What's a V.I.P.?
- Cream: This room is for special people, Mr. Big!
- Amy: There's supposed to be a really gorgeous room, past these stairs.
- Cream: There's no way we can get in, Amy! Let's go.
In Frog Forest, Team Rose's stage ends just before the giant mushroom section, so some comments go unused.
- Cream: I've never seen a mushroom that big!
- Amy: You're right! It's more like a giant tree than a mushroom!
- Big: Is that a Shiitake mushroom? I'm getting hungry.
- Amy: Is that all you ever think about?
In Hang Castle, Team Rose has to open the door with a switch, so some comments go unused.
- Amy: Aaah!!!
- Cream: Amy, look! The door's opened.
In Mystic Mansion, even though Team Rose can never get to the trials in the pocket dimension, there are voice clips for it.
- Big: We're underwater?
- Cream: I don't think we're underwater, Mr. Big. This is called a pocket dimension.
- Amy: Looks like we have to take on these three altars. Come on.
Even though Team Rose can never get to the three type trials in Mystic Mansion, there are voice clips for how to get past the Speed trial.
- Amy: Maybe we can use Homing Attack on those ghosts to get over there.
- Big: Use Homing Attack on the ghosts to get to the other side.
- Cream: We should use Homing Attack on those ghosts, to get over there.
Bullet dodging sequence
- Amy: They're shooting at us! Dodge the bullets by moving up and down!
- Big: Watch out! Get out of the way of the bullet!
- Cream: We're being shot at! Move up and down to dodge the bullets!
- Amy: Let's get up there!
- Big: Please! Move up!
- Cream: Move up!
- Amy: They're firing at us again! Dodge 'em by moving up and down!
- Big: They're shooting again! Must dodge the bullets: up and down!
- Cream: Here we go again! Just dodge them by moving up and down!
- Amy: Move down!
- Big: You gotta move down, or else!
- Cream: Move down!
There exist unused, alternate comments for when Team Rose is landing on a battleship in Egg Fleet in the game files.
- Amy: Let's land on that battleship!
- Big: I wonder if Froggy is on that giant ship.
- Cream: Let's try landing on that giant battleship!
There is a section in Final Fortress where some of the Egg Hammers and Heavy-Egg Hammers gather for the arguably hardest non-boss fight, as well as the last one. There is a Hint Ring nearby suggesting the use of Team Blast. Team Rose's stage ends before this a bit, but there are still recorded lines in the game files for the team's Team Blast hint.
- Amy: It's time for Team Blast!
- Big: Let's get them with Team Blast!
- Cream: We must attack, using Team Blast!
The self-destruct switch from Final Fortress was replaced with a fan instead, so some comments go unused.
- Amy: Phew! I thought we were goners.
- Cream: That was quite a challenge.
- Big: Why did it explode?
The laser cannons from Final Fortress were seen but they didn't activate, so some comments go unused.
- Amy: Yellow laser, fired!
- Cream: Yellow laser! Look out!
- Big: Uh-oh! The yellow laser!
- Amy: Blue laser, fired!
- Cream: Blue laser! Watch out!
- Big: Uh-oh! The blue laser!
- Amy: Red laser- Pink laser, fired?
- Cream: Look out! Red laser!
- Big: Uh-oh! The red laser!
- Amy: Giant laser cannons? Watch out!
- Cream: We should stay out of Mr. Laser's ways.
- Big: Wow, that laser scared me!
- Amy: Twelve laser cannons?! This is just my bad lucky day!
- Cream: Don't worry, Amy! We'll get past those laser cannons!
- Big: Lasers? Why are there so many of them?
Through hacking, a number of objects were left out of the levels due to some reasons such as bugs and whatnot. These include:
The fireworks object that was intended to be used for the Casino themed levels was not used in the levels. If they are loaded, they will trigger explosion sounds, albeit the animation is not in a smooth rate as regularly rendered in-game. When a player heads away from them, the game will crash.
Unused sound effect descriptions
One of the relocatable files contain the lines displayed during FMVs. The text includes descriptions of various sound effects marked as "(ES)", for example, "(SE) scattering stuff falling of the desk", "(SE) Machine gun fire" or "(SE) Explosion".
Special Stage programmer Hiroshi Iwasaki left a comment about a spline-related function:
- "///////////found a too nervous spline. I'll have to remake this function. please tell me firstname.lastname@example.org///////////"
Original Tornado Jump abilities
Amy and Espio had their original tornado jump ablities when the game was under development. These were replaced with their own tornado jump attacks after the developers came up with the ideas of Tornado Hammer for Amy and Leaf Swirl for Espio. In the E3 build, the leaf particles emit even though Espio had his original tornado scrapped. The tornadoes also play the following voice sound effects that go to these attacks:
|bank3e.pac||Espio||Summoning Ninja Power!||English|
Although the invisibility was programmed for Espio exclusively done using Leaf Swirl and not any other Tornado Jumps, the rendering of other speed characters through it are not used and enemies and frogs will still detect them. Amy's hammer however is also completely invisible. However, on the PC version the rendering function only renders the model if the player character is Espio.
Amy Rose wall cling
While the game was under development, Amy was able to cling on walls with the Triangle Jump with the running animation being used. However, the developers decided to revoke Amy's Triangle Jump maneuver in the final game.
Amy and Espio's Light Speed Dash
While Sonic and Shadow have the Light Dash in their moveset, the move was locked for Amy and Espio's moveset maneuvers in the final game. Like with Amy's wall cling, the running animation was used as a filter to prevent the game from crashing.
When fighting Metal Madness, the Hint Ring at the right makes Team Rose say that the boss will shoot fire if you grab his right arm. There is also an early image for the PlayStation 2 version of the game which shows that Metal Madness was originally going to have a white lower body.
- In the Alpha version of Sonic Heroes, there are several color schemes that differ from the final version. For Big, his belt buckle is black, and for Eggman in Robot Carnival, his goggles and eyes are white.
- In the Alpha version of Sonic Heroes, playable characters have no shadows, unlike the enemies.
- Some images from the Alpha version show Team Rose doing their victory pose at where Team Dark and Team Sonic finish their versions of the Stages, despite Team Rose's Stage ending much earlier than that in the final version.
- In the early Alpha version of the game, the Special Stages were far from finished, being graphically incomplete and only had the basic formations done.
- The Special Stages lack the water effect surrounding the courses which the final version has.
- The Alpha images for the prototype of the game's Xbox version show that Sonic the Hedgehog's Formation Leader icon had the Nintendo GameCube's button, hinting either an error or a placeholder icon.
- Team Sonic appear heavily shadowed for no reason.
- In the Alpha version of Sonic Heroes, Team Rose's Flower Festival lacks the petals and flowers display.
Prototype images of stages
- In the earliest video for Sonic Heroes, the Formation Signals for Fly Types have a wing on them. In the final game, the wings are replaced with the word "FLY".
- Several Formation Signals were removed from the final version.
- The first part of Team Sonic's version of this Stage is littered with Unbreakable Containers and several Dash Rings. In the final version, the Unbreakable Containers are replaced with Wooden Containers and the several Dash Rings were removed.
- Team Rose's Stage originally had more areas to explore.
- In the final game, Team Dark's final stretch to the Goal Ring is blocked and requires the usage of Dash Rings to pass over. In the early version of the game, this stretch of the Stage is more similar to Team Sonic's version. Several platforms have also been altered from the early version on the game.
- In the early version of the game, the enemies' health bars were without a speech bubble.
- In the early version of Team Chaotix's Stage, the player could reach the outmost areas of Seaside Hill like many of the other teams could. Their Stage also originally included some sections from Team Dark's version.
- In the early images for the game, Team Rose would begin Ocean Palace from the same starting point as Team Sonic.
- Some prototype images for Sonic Heroes show the Power Plant with black clouds in the background. However, these clouds were corrected in other images.
- In the final game, when the track breaks apart near the end of the Stage, Team Rose fights two Egg Pawns. In an early video for the game, they fight three Flappers.
- Parts of Team Dark's Stage where the player would have to use a Fan was added to Team Rose's version in the early game. However, in the final version, Team Rose's stage ends before the player can reach it.
- This screenshot, released on 28 August 2003, shows a lot of minor things that have been changed from the final version. Firstly, the Speed Formation Signal has a Power Sneaker icon on it instead of the word "SPEED", similar to how the Fly Formation Signal originally included a wing. Secondly, the Flapper is red instead of green. Also, the second alternate route through this section is missing.
- In the original version of Hang Castle, the player has to find 181 keys. In the final version, the player only has to collect ten Castle Keys in each mission. It is unknown if the object is still a "Key" or another item.
Prototype E3 cutscenes
Several changes were made to the game's cutscenes between the final version and the prototype version shown at E3:
- In an early video from e3.sega.com, the sequence with Eggman bobbing his head while pointing is lacking the machinery and robots found in the final version.
- Another video shows Sonic running through a Green Hill-esque area. In the final version, the checker pattern textures were changed to those of the first Stage.
E3 Demo differences
- If a player has not done anything for about thirty seconds, it will be forced to be sent back to the title screen via the "Coming Soon" screen.
- Sonic and Shadow's tornadoes have slower animation and the trails extend when Tornado Jump is used on an enemy.
- The tornado used for Leaf Swirl and Tornado Hammer are blue colored and was left unused since Team Sonic is the only playable team for the build. The codes to play as other characters were found on the GameCube E3 build by a researcher and can be used using the codes posted on the Sonic Retro thread.
- Because the game did not have complete voice overs at the time of E3, there was no chatter between the characters, and any Hint Ring would just show the text with a blue semitransparent rectangle surrounding it. The text is different in the final game, and the blue rectangle was deleted.
- Because there are no Power Cores in the E3 build, the Level-Up indicators do not appear on the characters' icons. Also, whenever the player passes a checkpoint, they would receive an item. For example, when passing with Sonic, the player got High Speed and when passing with Knuckles, the player would get a Barrier.
- The blue box was created for the interface to make the subtitle text easier to read.
- The Balloon-shaped Item Boxes are much smaller in the demo than in the final version.
- On the city levels (which crashes when accessed using a code), there are several model and texture differences (for example, the cloud texture quality is lower).
- At the very beginning of Seaside Hill, three Dash Rings would appear after a Fly Formation Change Gate, which would let the player fly to the top of a small hill. The final game does not include this.
- In the final version of the game, there are two flat platforms in Team Sonic's version when they first run into the Egg Pawns. The E3 demo does not have these platforms.
- In the E3 demo, there are three Rainbow Rings in the first section of Seaside Hill which can be used to take a higher route. In the final version of the game, they were replaced with a Dash Ring and a stone step
- In the middle of the Stage, where the split beaches can be found, there are nothing on the first beach except for a Cannon. In the final version of the game, columns and Egg Pawns were added.
- In the last part of Seaside Hill on the final version of the game, there would be an additional platform right in front of the arena and four breakable blocks. In the E3 demo, the platform is missing and there are only two blocks.
- Several Badniks and platforms in the final version of the game were not included in the E3 demo.
- The sky and the geometry is completely different from the final release as it only contains the rail collision on the bottom of the concrete train properties.
Egg Hawk Boss
- The rings and the breakable tower objects have not been placed and whenever a shrinking Sonic head transition occurs, the game will crash.
Gamecube's Sonic Heroes Prototype 10.8
The camera is not fully functional in a few minor places and tends to get slightly locked in some instances. This does not occur everywhere, but it is noticeable, as the angle becomes awkward. In some places, the camera is a tad different too, being closer to the characters, almost as if the no pre-scripted camera was present.
- The default language in this prototype is Japanese. However, the player can select English and others languages from the game menu.
- The Menu navigation is pretty strange. For most menus, it is a one-way, linear navigation unlike the free-form navigation in the final game. For the main menus, the player can only use up and down despite there being options to move left and right.
- In Challenge Mode, each character is in a completely neutral stance with blank expressions, and sometimes messes up.
- The Stages and bosses are separated.
- Finishing a Stage in Challenge Mode brings the player back to the start-up sequence, making it impossible to access the Bonus Challenges and Emerald Challenges, thus making Metal Madness and Metal Overlord impossible to access.
- Emblems have a very different, unfinished and unpolished look to them.
- "Special Stages" gives the player emblems. Also, the timer the player has is significantly larger than in the final game, and the amount of points that are gained from some actions is significantly larger than in the final game. The layouts are also quite different. However, "Emerald Challenges" seem unchanged.
- Some of the translations, particularly in the main menu, sometimes showed bad grammar in other languages.
- The game would display glitching and unfinished save/load slots.
- The names of the videos are already unlocked. In the final story, they are called "???" if not unlocked. However, the videos are present on the CD.
- The audio menu is partially in English and fully unlocked. However, the tunes do not work.
- Power Plant is much longer and ends at the bottom of the energy storage tank with a key behind the Goal Ring.
- Ocean Palace starts off where Team Sonic and Team Dark start off.
- The Team Blast for this team is slightly different. It is shorter, the animation is slightly different and it sounds slightly off compared to the final version.
- There are several layout changes in their Stages.
- In Lost Jungle, there are only fifteen Chao, not twenty, even though the objective list states there are twenty. The counter also says "x/15".
- The designers had not yet closed off the natural ending for Team Chaotix in Lost Jungle, allowing the team to get to Team Sonic and Team Dark's ending areas, but with a Back Ring instead of the regular Goal Ring.
- In Seaside Hill, the layout is quite different and the crabs are in different locations. The player also cannot complete the Extra Mission, as there are only nineteen crabs. There is also an end to Seaside Hill based on Team Sonic's path if the player passes the last Warp Flower.
- In Ocean Palace, the Warp Flowers do not exist, allowing the player to enter the turtle section. There are a lot of enemies, albeit they only come in two types. Also, some objects are missing.
- In Grand Metropolis, the final Warp Flower acts as a Back Ring, and there are only 84 enemies, not 85.
- In Bullet Station, the cannon does not work, but if the player dies, the capsules reset, allowing the player to finish the Stage anyways.
- Chaotix Recital is longer compared to the final PAL/NTSC-U release, matching the NTSC-J version of the final release.
- Bobsleds are not fully properly implemented in this version.
- Super Hard Mode contains an almost blank Seaside Hill which is believed to have no object layout; not even the Goal Ring is present, making completion impossible.
- Some Dash Panels are lower than in the final game. They almost look like part of the ground itself, rather than machines placed on the ground.
- Flowers look different, and their opening animation looks mechanical and unnatural.
- Certain lines that were taken out of the final version are present in this version, such as the explanation for using Big the Cat's umbrella.
- Shielded Egg Pawns get their shields suspended in the air when attacked by Tornado Jump or a three Power Cores-enhanced Homing Attack then they shortly disappear.
- Scoring is a lot more strict than in the final version, making an A Rank much more difficult.
- The game may crash upon entering the "Soundtrack Select" on the real hardware in some cases.
- Robot Storm plays the "Faker" music from Sonic Adventure 2.
- After destroying each one of Egg Albatross's three parts, all the playable characters will get sent into the sky for a short time before returning to the ground.
- Camerons can only be killed from certain angles by some of the Power Type characters, due to a bug.
- During the Metal Madness boss battle, the clouds enter the playing field, unlike in the final version. In the very last battle, there are not any clouds in the death animation at all.
- Metal Madness' voice is unfinished/unfiltered. The boss can also glitch if defeated by Chaos Inferno.
- Cutscenes have awkward stripes at the bottom of the screen.
- During the Metal Overlord boss battle, the player starts with 100 Rings. This fight may or may not load, depending on game's settings. The characters also say a phrase that is only achieved for the "A" rank for the Egg Emperor in the final game.
- Even when the Japanese language is selected, there are some lines the characters say in English.
- When the player goes out of range for the objects registered by the game and then back into range, all the objects will re-spawn.
- The tint for the rain effect when a Giant Frog is summoned is different.
- It is possible to use a Warp Flower as Charmy without needing to stand on the flower. This is done by hitting it from the side as it is opening.
- The paths in Grand Metropolis and Power Plant are not working perfectly and will even slow the player down rather than speeding him/her up.
- The Egg Emperor is harder while the Power Cores easy to get, in some cases being placed right in front of the player's start position. Also, the Thunder Shoot does not stick to the Egg Emperor, its animations are very short, it is very fast and the collision boxes for its attacks are noticeably larger. As the boss is difficult, it could have been considered to be one of the final levels for Super Hard Mode.
- Some limbs for Shadow the Hedgehog seem to be made from his parts in Sonic Adventure 2.
- Triangle Dive seems to be faster than in the final version.
Gamecube's Sonic Heroes Prototype 11.18
- The debug menu is accessible by pressing L+R buttons at the same time.
- The title screen looks similar to that for the E3 Demo released on the Xbox.
- All the music and CGI cutscenes are unlocked from the beginning.
- Inside the game, some of the music is changed. For example, Mystic Mansion is missing a guitar while some of the Versus mode tracks are WIP tracks.
- The Blue Tornado and Black Tornado cannot be canceled.
- In Team Chaotix's Seaside Hill, the platform with the block and Spring in the first Cannon area has not been removed yet. The player can see it in Team Sonic's Seaside Hill.
Sonic Heroes/Mario Kart: Double Dash!! Bonus Disc

Early revisions of the songs in Sonic Heroes popped up on the internet before the game was released:
During the development of Sonic Heroes, the team was originally used to edit/test levels when creating levels for each team. Aside from debugging, the team involves members from the Chaotix except that Big the Cat is in place of Vector along with level layouts from Team Sonic outside of Super Hard Mode which Espio the Chameleon cannot perform the Light Speed Dash technique in certain areas with ring paths in-order to move on to somewhere else in the level and the characters are voiceless aside from Hints and it's collisions.
A few side effects when playing this team on level cutscenes, boss level cutscenes, 2 Player races and Emerald challenges include crashing, the first rival boss can properly be loaded albeit Team Sonic will be fought except that Team Dark's name and icons are loaded, the mission text does not appear on the level loading screen in single player mode and using Team Blast results a black background with Espio and Charmy playing the instruments and Big dancing. Also, there is no way to escape from it requiring the player to restart or quit the level in-order to get out of it.
