Audio Differences

This is a sub-page of Proto:Sonic Heroes/GameCube prototype 10.8.

Every voice clips are available, all of Omega's voice clips are filtered, and the soundtrack is a lot further along compared to the 9.28 prototype, but digging deeper reveals that the audio is still in an unfinished state. Although some tracks also sound closer to the final than the version from an unknown build, most were either unchanged or contain more differences.

Music/Song Differences#

Changed Tracks#

There are numerous songs in this build that have differences to their final counterparts, from subtle to obvious. The versions of Seaside Hill, Sea Gate, and Rail Canyon that can be found in the E3 2003 prototype and 9.28 prototype (albeit without Sea Gate) have been updated and sound more or less identical to the final by this point.

Unused Tracks#

Because you can't listen to any music in the sound test menu in this prototype, the following tracks are present on the disc, but go unused as they can never be heard in-game:

Even though "Follow Me (Theme of Team Rose)" does properly play, it's only partially used, as the song gets cut off due to the credits ending too early.

Missing Tracks#

Not all tracks from the final are present in this build. The following ADX tracks that are missing/don't exist in this build are listed below:

SNG_BTL04.adx
SNG_BTL05.adx
SNG_E0017.adx
SNG_E0117.adx
SNG_E0404.adx
SNG_STG24TC.adx
SNG_STG24TR.adx
SNG_STG24TS.adx
SNG_SYS2.adx
SNG_SYS3.adx
SNG_SYS4.adx

While all of these would remain unchanged in the final game, there are two noteworthy entries:

• SNG_SYS2 had its audio swapped with SNG_SYS1 in the final (which is shown above).
• SNG_E0404 uses the rest of the verse from SNG_V01_MAIN (which is also shown above and used as the opening theme in the final) for the credits theme in the retail version.

Sound Differences#

General#

To do: Particularly everything.

• A lot of the sound effects are jittery.
• Some of the dialogue tends to either lag or get cut off (rendering some lines unused entirely).

Voice#

A number of changes can be found within both some of the early cutscenes and the AFS archive, from identical to notably different.

Omega#

To do: Find the remaining Omega voice clips that get cut off by buzz sounds.

Omega's voice clips are largely identical to the final, except now some of his lines get cut off by buzz sounds. Somehow, one slips by in the final PlayStation 2 version for Casino Park.

Metal Madness#

Similar to the prototype before it, all English voice clips for Metal Madness and Metal Overlord do not have echo effects yet, so there are numerous differences compared to the final.

Metal Overlord#

Some of his lines get cut off in-game, therefore making some of his audio go unused. Weirdly enough, certain lines get cut off by buzz sounds, similar to Omega above.

Neo Metal Sonic#

At this point in development, most of his English audio have been filtered in the cutscenes and are more or less identical to the final version. However, during the cutscene for when Neo Metal Sonic transforms to Metal Madness, none of his audio there are filtered.

Unused Voice Clips#

Certain voice clips never get used in this prototype for one reason or another.

Team Select#

As with the 9.28 prototype, the voice clips that would play for when the player selects a team can all be found on the disc, but since the game goes right straight to the cutscenes/stages, these go unused.

Finalized Cutscenes#

The finalized cutscene voice clips for Charmy, Dr. Eggman, and Neo Metal Sonic are present in the AFS archive. Since the early cutscenes are used instead, it's completely the other way around.

Omochao#

Just like the 9.28 prototype, all of his menu voice clips are present on the disc. Due to his menu hints not being implemented in this build, these never get heard in-game, rendering them unused.
