Sonic Heroes lets you play as four teams of three, all consisting of a Speed, Fly, and Power type character, across 14 stages with varying layouts and objectives for each team.

It's the last 3D game in the series to feature the Adventure era's English voice cast before they switched to the 4Kids crew, the first time the rest of Team Chaotix showed up in a game since the mid-90s (minus Mighty), and is generally seen as one of the quirkiest games in the series. Its reception is very divisive, with people either loving or hating it.

Also notable for being the first mainline Sonic game to be released for the PlayStation 2 and Xbox.

Hmmm...
To do:
Bugs page begging to be made for this game. One note for when that's made is that the Team Blast quick build-up glitch (done by pressing Attack and switching to another teammate while using the Fly character at the same time) doesn't work on the PC version. Also, in the cmn_effect.txd file in the PC version, the blue crescent particle, "ef_solid", is missing and Espio's shuriken explosion would disappear with the particles being invisible as a result.

Unused Techniques

SH Amy Original Tornado.png SH Espio Green Tornado.png
Amy and Espio originally shared Sonic and Shadow's Tornado Jump techniques before they were given their own unique moves. These Tornado Jumps were far enough into development to have unique colors (pink for Amy, green for Espio) and corresponding voice lines.

SH E3 Espio Original Tornado.png
In the E3 prototype version, leaves still float around Espio when using the original Tornado Jump.

This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: How do you enable this for other teams, and can Sonic/Shadow do this too?

Additionally, Chroma Camo can be enabled for other characters besides Espio.

Unused Textures

The textures can be accessed similarly to Grand Theft Auto III. By using the Magic.TXD editor one can view, edit, and create textures for all platforms Sonic Heroes was released on.

indirect_test.txd

SonicHeroes-Tikan 01.png
This tile texture was used to test the indirect shader before applying it to an object or a part of the level geometry.

stg06.txd

Textures meant for fireworks in the casino levels. However, no firework models were placed in those levels, leaving them unused.

stg09.txd

SonicHeroes-D pow64.png
A texture meant for objects that emit powder particles, such as the mushrooms in the jungle levels. They use "ef_p00" from "cmn_effect.txd" instead.

s12.txd

Used (from the stage effect txd archives) Unused (from s12.txd)
SonicHeroes-M11 ef01.png SonicHeroes-M11 ef01 s12.txd.png

A smoother, more smudgy looking version of Mystic Mansion's teleportation particles.

stg73.txd

GameCube/Xbox/PC PlayStation 2 Xbox (unused)
SH d frogc2 stg10.png SH d frogc2 stg10 ps2.png SH d frogc2 stg73 xb.png

Stored only in the Xbox build for 2 Player Frog Forest, is a color variation of the black poison frog with less green in RGB value compared to the one found on Lost Jungle, normally used for the PlayStation builds, except in higher quality 256x256 resolution.

e3Adv.txd

Included in the textures for Stage 14, Final Fortress, is a 512×512 version of the sky texture. Only the 256×256 version is used in the stage and subsequent boss fight. The TXD file also includes the contents of "indirect_test.txd", "e3Adv.txd", and "play_ground.txd".

Strangely, the PC version is essentially "padded" with duplicate texture files, such as "event____.txd" files. Also, "comsoon.txd" is empty.

Teleporter switch textures were also in "s71.txd" for Xbox.

Unused Objects

Careful, you'll lose an eye.
This page or section needs more images.
There's a whole lotta words here, but not enough pictures. Please fix this.

There are several stage objects that go unused (located in the dvdroot folder):

  1. stg06_kw_hanabi_blue.one - Blue Fireworks
  2. stg06_kw_hanabi_green.one - Green Fireworks
  3. stg06_kw_hanabi_purple.one - Purple Fireworks
  4. stg06_kw_hanabi_red.one - Red Fireworks
  5. stg06_kw_hanabi_yellow.one - Yellow Fireworks

adv_ef_warpb.dff

Used Unused
SonicHeroes-Adv ef warpa.png SonicHeroes-S11 switch effect.png SonicHeroes-Adv ef warpb.png
Used (In-game) Unused (In-game)
Warp effect commonly used for most teleportations. Orb switch warp effect used for the castle themed levels. Used in-game after hacking the codes in "Tsonic_win.exe" for PC.

An unused silver swirl warp effect found in the "comobj.one" archive of the dvdroot folder. Unlike the two other warp effects, this one rapidly permeates the screen and quickly teleports the player to another position. It can be enabled in the PC version by hex editing the byte at an object offset such as 717FB from 58 to 60 and 71967 from 54 to 5C. For the orb switch, their codes are 68 at 103132 and 64 at 10333D.

For the GameCube version, use this code to replace the gradient warp with the swirl one:

Demo Gameplay

SH Demo Gameplay.png
The gameplay demo that would play after idling long enough on the PlayStation 2 and GameCube versions' prototypes were left out of the PC version. It can be re-enabled by replacing the original array at 5698A with 80 F9 06 0F 4D CB. If done correctly, the gameplay demo will play after the opening movie.

Transparent Magician Effect

Hmmm...
To do:
Add codes for other versions.

SH Magician Transparent.png SH Bishop Transparent.png
For the Magician/Bishop Robot that appears in castle-themed levels, there are material opcodes in the PC version starting at 212D5F (612D5F in RAM) which render the robot transparent with additive alpha blending which was never used by any of the enemy's techniques. However, editing the byte array at 210F83 from 00 00 80 3F to a lower float code in little endian may render a transparent version of the robot after it appears on the placed location.

For GameCube, apply the Gecko codes below:

10.8 USA
48000000 800030C8
DE000000 80008180
300815C8 D00302AC

C0210000 38210004
60000000 00000000
E2000001 80008000

There are also several material flags that aren't used in the game, of course including ones from unused objects, including the Fireworks object at 0xB4AC3, the hint collision (which is a 72 flag pointer) at 0x75137, the green thunder at 0x48A700 and the three powder objects at 0x468ED4 (Green), 0x468EE4 (Pink), and 0x468EF4 (Yellow) on PC.

Inaccessible Areas

Hmmm...
To do:
Many stages have inaccessible areas that have yet to be documented here. This channel has several videos showing Rose where they shouldn't be. Based on the Seaside Hill video, some areas also seem to have unique object placement variations that go unseen since you never go to them.

Due to how the levels are structured, all four teams can theoretically access every area in a level - including those that are "exclusive" to one team. This is most evident with Team Rose, as their levels are the shortest and either cut out roughly the first third of it (such as Power Plant) or physically block them from proceeding at a certain point (such as Lost Jungle).

However, with the use of glitches and/or hacks, teams are able to go to places they weren't meant to. And oddly enough, several of these areas have remnants of them being able to go there normally, such as unique object placements or otherwise unused lines of dialogue.

Team Sonic

Sonic Heroes MM Inaccessable area.png
Team Sonic in Team Chaotix's final area of Mystic Mansion, accessibly only through using hacks. There doesn't seem to be any way to leave due to the lack of a teleport flower, let alone a way to open it.

Original Rail Canyon Team Chaotix mission

Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: It's a bit confusing what the text is even talking about. And are there any other differences aside from this small area? Are there other stages like this?

These codes restore the original Rail Canyon used for other teams aside from Chaotix on the team's stage mission.

PC:

  • 0x4B69C: 0x08000000
  • 0x55894: 0x08

Hidden Setting

In the PC version, adding the line

Charmy_Shutup 1

to "%AppData%\SEGA\SONICHEROES\sonic_h.ini" will disable all voice clips that do not have accompanying subtitles (such as attacks, idling, and scoring).

Oddities

Hmmm...
To do:
Some of this and the next section should probably either go into the Platform Differences sub-page, the Bugs page if it's ever made, or potentially a Regional Differences sub-page if there's enough undocumented differences.

As seen here, there's a self-destruct switch out of the wall in Team Rose's Final Fortress, to the left of where it normally is. If you fly next to the left wall, you'll be able to see it, and you can actually press it if you use glitches.

Voice Clip Oddities

Hmmm...
To do:
Rip the clip.

A lot of voice files in the PC version are empty for unknown reasons, most notably Cream's A-rank line. In the versions that don't have this problem, she says "I'm so happy, I want to tell everyone!". The subtitles for most of the other empty voice clips will still appear, however.

There are some clips in-game for when the characters explain the bobsled controls. However, these explain that if the Flight character is thrown off, the bobsled won't be able to jump. The order for character removal is Speed, Power, Flight, so when the Flight (i.e. last remaining) character is thrown off a life is lost. This hints that previously, the order for character removal was different or random.

When fighting Metal Madness, the Hint Orb at the right makes Team Rose say that the boss will shoot fire if you grab his right arm (the flame-shooting arm). Maybe this battle was different earlier in development, because you can't do anything even remotely close to grabbing in it, and the moment he decides to shoot flames appears to be random.

Final Fortress Laser Muzzle Flash

SH FF Laser Front.jpg SH FF Laser Behind.png SH FF Laser Side.png

While it's impossible to see normally, the lasers fired in Final Fortress at the rails actually do have a muzzle flash effect while firing. However, because of backface culling set by the effect's world render pass, the direction of the normals, and how briefly the laser appears before it goes offscreen, the player can never see it.

Regional Differences

Sonic Heroes PS2 - TV Setting Screen.pngSonic Heroes PS2 - TV Setting Test.png

Present only in the European versions of PlayStation 2 and GameCube is a unique screen that allows the user to switch between 50hz and 60hz (with a compatible television), as well as a Test option (for the European version of PlayStation 2 only) previously seen in the Dreamcast versions of Sonic Adventure and its sequel. Interestingly, the artwork for Ocean Palace in the background can be found in the E3 prototype, albeit as an unfiltered PNG file. The GameCube and Xbox versions lack this feature, instead setting the resolution by checking the console's internal region.

  • The American and Japanese PS2 versions are the only versions to have a voice language setting, which lets you choose between the Japanese and English dub as well as being able to change the language for text. The GameCube, Windows, and (European-only) PlayStation 2 versions only have a menu to change text language. The Xbox version has both voice languages present, but has no language menu and uses the set console language.
  • The European PS2 release (when set to 50hz mode) has a glitch where the game sometimes registers two button presses instead of one, which can cause issues during gameplay (e.g. doing an air dash instead of jumping, not selecting the wanted character, etc.).
  • The European GameCube version provides the option to play in 60hz. However, this just takes the 50hz mode (which already plays at the right speed and only skips frames) and forces it to run at 60hz, instead of properly adjusting the gameplay speed.
  • In the PS2 version, the Cross (X) and Circle (O) buttons were not switched from their Japanese functions (being no and yes, respectively) in the North American version. The button assignments were switched in the European release.
