Sonic Adventure 2 (May 7, 2001 prototype)

A late review prototype of Sonic Adventure 2 for the Sega Dreamcast.
==Notes==
* Built almost a month before the final retail versions.
* This build contains all the content from the main game and hasn't been truncated for demo purposes.
* The sound effect cue during the opening cutscene before the title screen is slightly different.
* The final retail release's saved game is not compatible with this prototype. It will load but it won't match the progress you made in the retail version.
* While the English translation is complete, there are various grammar/spelling mistakes throughout the script that still have yet to be corrected.
* All the DLC themes are included and enabled by default.
* The tutorial menus are barely translated and are very broken.
* While it's possible to get 180 emblems in the prototype, Green Hill Zone cannot be activated. However, Green Hill Zone is present in the game and is playable.
* The message after collecting all 180 emblems in this build indicate that new 2P versus mode and action stages (plural) were meant to be unlocked at one point. In the final, it only mentions the availability of a 'secret' stage, which is Green Hill Zone.
* There are some debugging features enabled in this build:
** Hold down X while the game is paused to display memory info.
** Press Y while the game is paused to display player coordinates.
** Press START on Controller 3 while in a Chao Garden to bring up an extensive debug menu. The debug menu can be navigated using the analog stick.
* If you restart after dying on a treasure hunting stage, the emerald locations don't change.
* Stage differences:
** The missle part in Metal Harbor is more difficult in this prototype.
** There's an additional pully added around the area you acquire the air necklace in Aquatic Mine.
** For the driving stages, the cars have collision that cause you to recoil away from them. In the final, the cars tople over when you hit them instead.
** An additional ring was added toward the end of Rogue's driving stage to mark when the stage is supposed to end.
** Various hazards were added around the last key in Pyramid Cave, making this part very difficult. This was changed for the final, making it so you only have to dodge enemy projectiles.
** Final Rush has many different sound effects.
** Additional meterorites were added on the final Sonic/Shadow fight, making it more likely to run into them in the prototype. These were moved further away from the path for the final.
** Green Hill Zone lacks many sound effects. The animal collection sound effect is higher pitched. 
* Chao Garden differences:
** Chao change to their hero or dark skin color faster when petting them in this build. 
** Chao don't seem capable of evolving naturally in this build.
** Chao stay full after eating for a near indefinite amount of time.
** Tails and Robotnik's out of vehicle attack sound effects are different.
** Tails lacks the sound effect when he flies.
