Proto:Sonic Heroes/Mario Kart: Double Dash!! Bonus Disc
This is a sub-page of Proto:Sonic Heroes.

As a reward for pre-ordering Mario Kart: Double Dash!!, customers received a bonus disc containing demos and videos of various upcoming games. One demo was Sonic Heroes (also known as Sonic Heroes: Trial Version as shown on the title screen), containing some major differences from the final. Despite being closer to the final, some content appear to be from an earlier build.
Contents
Technical Differences
- This is currently the only known build where all voice clips in the AFS archive are located to a different file, which is called SH_VOICE_TGS_E.afs. The Tokyo Game Show demo never uses the English voice tracks, as the Japanese ones were used instead.
- All of Team Rose and Team Chaotix' files have been completely removed since they aren't playable in this build.
- The only audio files related to the levels that are present on the disc include Seaside Hill, Grand Metropolis (which is shown below), Ocean Palace, Rail Canyon, and Bullet Station.
- The cutscenes, bosses, and every other levels are missing from the disc, unlike the 9.28 prototype.
General Differences
Startup Screen
- It's STILL possible to skip the startup screen until the stage select screen (similar to the E3 version), which is something that you can't do in the final.
- This demo still uses the E3 Sega and Sonic Team logo, despite the "ADX" logo using the final version.
- The demo sequences from the previous builds have all been removed at this point in development.
Graphical Differences
Title Screen/Logo
| Trial Version | Final |

This demo has the final title screen, but there are a few differences to note about here:
- Sonic, Tails, and Knuckles' graphics were split into their own textures in the final.
| Trial Version | Final |
|---|---|

   |
- The "TRIAL VERSION" logo is displayed on the title screen.
- The "PRESS START BUTTON" graphic was changed to "Press START" in the final release. This was also seen in some older builds of the game.
- The title screen lacks "Licensed by Nintendo" (which is also in the GameCube's E3 version).
Cutscene Differences
Opening Cinematic
| To do: A video is needed. |
Although the opening is now included, it lacks sound effects. This is actually identical to the one shown at Tokyo Game Show (only here the logo is in English), which can still be found unused in the 9.28 prototype.
Menu (Stage Select)
| E3 2003 | Trial Version |
|---|---|
 |
 |
There are only two teams and two levels playable: Team Sonic (Seaside Hill) and Team Dark (Bullet Station). The stage select screen resembles the earlier E3 2003 demo:
| E3 2003 | Trial Version |

|

|
As such, Bullet Station uses Rail Canyon's icon, despite that level not being playable in this demo.
Hint Box
| Trial Version | Final |
|---|---|

The blue semi-transparent rectangle box from the E3 demo for the subtitles has been removed, but the subtitles retain the additive blending.
"Coming Soon!" Screen
Similar to the E3 prototype, beating either stages or getting a game over will give you the "Coming Soon!" screen and take you back to the title screen. There is one other way to see this:
- The game will automatically reset after the player is inactive for a short while.
Unlike the E3 version, however:
- The timer counts up, something that was unused in the E3 build. This no longer limits the gameplay sessions to just be 10 minutes.
Level Differences
 | This page or section needs more images. There's a whole lotta words here, but not enough pictures. Please fix this. Specifically: There's a lot that needs to be compared, some of which match/are similar to the earlier E3's layouts. |
- Some level objects have been rearranged.
Bullet Station
| Trial Version | Final |
|---|---|
 |
 |
Because there are no Special Stages in this demo, the Key was replaced by a Shield.
| Trial Version | Final |
|---|---|

There is a Floating Item Box that was removed in the final since there's no way to reach it. In addition, a Klagen can be seen at the end of the level of this demo.
| Trial Version | Final |
|---|---|
 |
 |
A Goal Ring replaces the Case that would normally take you to the next section. Due to this, Team Dark's Bullet Station is a lot shorter than the final version.
Audio Differences
Sounds
 | Unfiltered Omega's Voice Sounds familiar, actually. |
 | This page or section needs more audio. There's a whole lotta words here, but not enough audio. Please fix this. Specifically: Please rip the audio from this demo and compare some of them to the final (P.S. The Goal Ring sound.) |
- Some sounds are different.

Unused Area
Extended Bullet Station
Although Bullet Station is accessible in this demo, an area before the second giant cannon for Team Dark can't normally be reached, as the level ends a lot sooner than how the final version does. Due to this, the infinite flight cheat for getting over the inaccessible area is required. It's rather unfinished, as there's very few objects present.
Unused Voice Clips
Some voice clips go completely unused in this demo due to that level not being accessible for that team. Team Sonic can't access Bullet Station, and Team Dark can't access Seaside Hill. In addition, Ocean Palace, Rail Canyon, the select screen from the final, and the 2-player mode are completely inaccessible for both teams in this build. As such, nearly all of Omega's voice clips as shown in his page above are not used. However, using the "Klagen Lock" glitch in Bullet Station will trigger one of Team Sonic's voice clips. This glitch was fixed in the final.
Grand Metropolis
Present on the disc is Knuckles' second hint voice clip of Grand Metropolis, a leftover from the Japanese version. Not only is that level not at all playable for either teams, but the English voice tracks relating to it are also completely absent from the disc. How this even got here is anyone's guess.
