Sonic Adventure 2 (2012)

Prototype Info Bugs

Differences from Previous Versions#

Menu Differences#

GameCube	2012

The menu was completely overhauled in this version:

• The "Options" button was renamed to "Help & Options".
• Button prompts have been added to the bottom of the menus.
• The Omochao tutorial was replaced with a tutorial resembling a manual.
• The text language option is now a part of the launcher. Though the voice language option is still a part of the options menu.
• Somehow, the music has somehow gotten even louder.

• When the game is saving data, the message that appears on the top right is slightly different.

Graphical Differences#

• Some HUD graphics were remade in HD, which is done by storing them in .PAK files and patching them on the fly.
• 16:9 aspect ratio support was added, though some cutscenes still display in 4:3 due to using video effects.
• All references to SOAP shoes were removed for copyright reasons due to SOAP's licensing agreement with Sega being expired.
• Omochao's hints from Sonic Generations were added between loading screens.

Dreamcast/GameCube	2012

• The recap backgrounds seen when resuming an unfinished story were redone in the 2012 version. Although it's barely visible, Sonic's artwork in the background was updated to the SOAP shoes' version, whereas the Dreamcast and GameCube versions are instead based on an alternate version of his portrait that isn't wearing the SOAP shoes.

Dreamcast/GameCube	2012

• The health icon was changed from a cross to an 'H', likely due to the ICRC being notoriously strict about how their emblem is used in entertainment since the original's release.
• All artwork previously portraying Sonic wearing his classic shoes were replaced with the SOAP shoe versions.

Stage Differences#

• All of Big's cameos in levels that were removed in the GameCube version are restored, except for ones in Wild Canyon and the multiplayer mode.

Route 101#

• The billboards that were present in the Dreamcast and GameCube versions are strangely absent in the 2012 version.

Dreamcast/GameCube	2012

Unused Graphics#

Unused Font#

Used for debugging purposes.

Title Screen Demo Texts#

The background for the title screen includes text for trial versions. While they are used in the console versions, the PC version doesn't have a trial version.

Scene Select Icon#

The icon for the Hero Story's Sonic vs. Shadow 2 scene from the Dreamcast version was given a new icon in this version despite it still going unused.

GameCube Version Leftovers#

As mentioned above, the .PAK files are patched in on the fly to display the HD HUD and remove SOAP shoes references; deleting these files will make the game use the original PRS files, which were left unmodified from the GameCube release.

Platform Differences#

Iron Gate Lighting#

Xbox 360/PS3 (Shown: GameCube)	PC

A bug in the PC version causes Eggman's flashlight to illuminate the entire stage in Iron Gate and Lost Colony. The stages themselves are identical to the GameCube version, which can be seen on the Xbox 360/PS3, where the bug isn't present.

Stage Select Background#

Xbox 360/PS3	PC

The ARK section of the stage select map has difficulties displaying in 16:9 due to its narrow size. The PC version stretches the image to the size of the screen, but it doesn't apply to the transition between the two sections of the map, resulting in a notable snap before and after.

Background Text#

Dreamcast	Xbox 360/PS3

The Dreamcast version's scrolling text for the main menu background was remade, but it only shows up in the console versions. It isn't used in the PC version, but the code for displaying it is still there and it still appears in the in-game manual's screenshots.

Options#

Dreamcast	GameCube

Xbox 360	PS3	PC

The buttons in the options menu is different for each version. Interestingly, the Dreamcast, GameCube, and PS3 versions read "OPTIONS" on the top left. On Xbox 360 and PC, it reads "SETTINGS".

Memory Card Select#

Dreamcast	GameCube

Xbox 360	PS3	PC

The Memory Card select screen on all versions differ. The Dreamcast version allows you to choose 8 VMUs, allowing up to 88 main save files per console, assuming nothing else is stored on the VMUs. The GameCube version allows you to choose 2 Memory Cards, which allows a different amount of save files depending on the type. The Xbox 360 version allows you to choose between multiple storage devices. The PS3 version will, by default, save to the HDD. The PC version will save the game data to the game installation.

Xbox 360	PS3

The Xbox 360 and PS3 version have a warning about auto-saving. The Xbox 360 displays the message after selecting a storage device. The PS3 displays the message when the game is starting up. All other releases do not have this.

Leftovers from Previous Versions#

Tutorial Menu#

Previous versions of the game had a Tutorial option in the Extras menu where Omochao would provide the player with a guide on how to play the game. This tutorial was replaced in this version, but the original Omochao version (as well as the option for it) are still in the game. This tutorial menu is identical to the one used in the GameCube version.

Original FMV Format#

In the Steam port, all FMVs are stored in the MPEG Sofdec (SFD) format, but the original MPEG (M1V) files are still present. Format aside, the videos are identical.

GameCube Memory Card#

To do: Find out if the GameCube model still exists.

In the Steam version, Data_DLL.dll's cardObj export contains a list of four models of GameCube memory cards in a box with a slot indicator above them, one each for Slot A and Slot B in English and Japanese. Additionally, fileSelect.prs, fileSelect_e.prs, fileSelect.pak, and fileSelect_e.pak contain textures for the GameCube model that appears in the back of the GameCube version's save file select screen.

Debug Menu#

For some bizarre reason, the Debug Menu for the Dreamcast and GameCube versions is still present. The code to display the text was removed, but the options still function.
