Proto:Sonic Adventure 2 (Dreamcast)/The Trial/Unused Content

From The Cutting Room Floor
Jump to navigation Jump to search

This is a sub-page of Proto:Sonic Adventure 2 (Dreamcast)/The Trial.

While most of these are used in the final, they go completely unused in this build, though there are some straight up unused ones.

Leftover Data

  • Examining 1ST_READ.BIN reveals that early animation data, start and end positions for half of the stages, and placeholder ranking information for Mission 1 exist within the game. Every main character (Sonic, Shadow, Mech Tails, Mech Eggman, Knuckles, Rouge, Tails, Eggman) has an animation list dedicated to them, but the internal IDs for said animations and their character models are different.
  • The internal stage list referenced by the characters' positioning data and ranking information reaches up to ID 28 (Pyramid Cave). Notably, Lost Colony's stage ID - 27 - is not referenced in either the placeholder ranking information or in Mech Eggman's start/end position values. Knuckles also references ID 53 in his positioning data, which is the stage ID for King Boom Boo in the Dreamcast version.
  • Ranking information for each stage aside from City Escape lists the following values:
Rank Score
D Rank 2,000
C Rank 5,000
B Rank 10,000
A Rank 15,000
  • Egg Quarters and Pyramid Cave do not have placeholder ranking information, despite being referenced in Rouge and Sonic's positioning information, respectively.

Unused Graphics

Seeing as this demo is only a sliver of the final, there are bound to be unused graphics. Most of these are used in the final, but are only in the demo because they're grouped with textures that are needed for the demo.

City Escape Map

SA2TheTrial CityEscapeMap.png

Available as a simple bitmap image file on the ROM is a map of City Escape. This map is used for geometry culling when entering specified areas of the level, a feature that is present in all versions of the game.

Capsule Graphics

SA2TheTrial Knuckles.png SA2TheTrial Tails.png SA2TheTrial Shadow.png SA2TheTrial Rouge.png SA2TheTrial Eggman.png

SA2TheTrial Bomb.png SA2TheTrial Life.png
Various icons for item boxes from other stages that aren't used in the demo.

SonicAdventure2 RandomRing.png
This one is unused in both the demo and the final though.

Two-Player Win Indicator

SA2TheTrial 2Player.png

The graphics that display on the bottom of each player's screen during two-player are on the ROM. 2 Player Mode exists but can't be accessed normally. The second graphic is slightly transparent, so a black background was added for visibility.

Other Unused Graphics

Hmmm...
To do:
See what's here.

There are more textures used on things outside of the City Escape stage, including the Mystic Melody door, the hint computer for Knuckles/Rouge stages, and the textures for an upgrade point.

Unused Text

Early Level and Boss List

An unreferenced stage list can be found in TEXT_E.PRS and TEXT_J.PRS:

BASIC TEST
KNUCKLES TEST
SONIC TEST
GREEN FOREST
WHITE JUNGLE
PUMPKIN HILL
SKY RAIL
AQUATIC MINE
SECURITY HALL
PRISON LANE
METAL HARBOR
IRON GATE
WEAPONS BED
CITY ESCAPE
RADICAL HIGHWAY
WEAPONS BED 2P
WILD CANYON
MISSION STREET
DRY LAGOON
SONIC VS SHADOW
TAILS VS EGGMAN
SAND OCEAN
CRAZY GADGET
HIDDEN BASE
ETERNAL ENGINE
DEATH CHAMBER
EGG QUARTER
LOST COLONY
PYRAMID CAVE
NO NAME
BIG FOOT
HOT SHOT
FRYING DOG
King Boom Boo
GOLEM(an assumed name)
THE BIOHAZARD(an assumed name)
CART
EXTRA GAME:CART
CHAO GARDEN

This remains in the final, unused, but there are some differences to note:

  • Wild Canyon is listed without the "2P" suffix.
  • In the final, Weapons Bed 2P is just listed as Weapons Bed again.
  • Egg Quarters is listed as Egg Quarter.
  • Tails vs. Eggman 2 lacks an entry, suggesting it hadn't been implemented at this point.

Mission Entries

Although City Escape's first mission is normally the only seen mission entry, other missions have entries in MISSIONE.PRS; seems like none of the actual entries (including the used one) were ready yet since they are all just <NO MISSION> when English is the set language.

Mission text exists for the Japanese language setting in MISSIONJ.PRS and is in a more complete state, though aspects such as certain time limits for the available Mission 4 strings are different from the final version. The mission text list contains space for 250 entries, but the last filled entry in the file is the 145th, which corresponds to Pyramid Cave's Mission 5 text. Mission text that would correspond to the Kart levels and Crazy Gadget's second mission do not exist in this file.
