Tournament Disk

This is a sub-page of Proto:Sonic Adventure (Dreamcast).

This prototype is documented on Sega Dreamcast Info.

This prototype is documented on Hidden Palace.

The Tournament Disk is a version of the game used for a special Sonic Adventure tournament held during the Sega Dreamcast Mobile Assault Tour, a 22-week tour sponsored by IGN that was used to promote the upcoming Dreamcast console.

This version consists of Sonic's Emerald Coast with a 2-minute time limit. The other stages exist in the files, but are identical to the final version.

Differences#

There are no major differences, since this build predates the final by only 2 days. Minor differences include:

• The title screen uses the version of Open Your Heart that plays during the cutscene where Sonic transforms into Super Sonic in the final story:

• The title version of Open Your Heart is present, but unused.
• The title screen lacks the animation and rippling effects of the final, instead just fading in.
• While the English voice and text localization files are finalized, the German, French, and Spanish ones are not.
• The ADX files present in this build correspond to the final Japanese version, being in 44kHz bitrate, instead of the 32kHz bitrate of some music files in the US version.
• The NIGHTS_A.ADX, SSRACING.ADX, and NIGHTS_S.ADX music files used by the DLC are absent.
• The TGS_SOUSA_x.PRS files are left over from the Japanese version. They were removed for the final US version.
• Resources for the website are not present.
• The demos that play after idling on the title screen do not exist.
• The disc has the same Extras as the Japanese version.
• When the stage is cleared or the timer runs out, the scoreboard doesn't disappear until Start is pressed.
• Some ADX files that are present in both the Japanese and US releases are absent.
• The file 1ST_READ.BIN (which contains the program to execute and load the game) is slightly different than the final's.
• The PRS files are slightly different due to the minor changes in 1ST_READ.BIN, though there are not enough byte differences to indicate major changes.
• There is a bug in which Sonic gains significantly more air momentum than he is supposed to during his descent after a homing attack. This happens if you keep holding the same direction on the analog stick before and after the move.

Notes#

• The game starts in Emerald Coast with Sonic having all of his upgrades.
• When the timer hits 1:55:00, numbers start flashing on the screen counting down from 5 to 0.
• when the timer reaches 2:00:00, the screen freezes and the scoreboard is displayed. If the player beats the stage in time, the victory animation will play and the camera will zoom out after a few seconds, then it will fade back to the title screen.
• There isn't a mission complete card, even though a "Rescue Tails!" card appears at the start of the stage.
• Sonic doesn't say "Yeah, not bad!" when the stage is over.
