Final Rush has many different sound effects. This was changed for the final, making it so you only have to dodge enemy projectiles. Various hazards were added around the last key in Pyramid Cave, making this part very difficult. An additional ring was added toward the end of Rogue's driving stage to mark when the stage is supposed to end. In the final, the cars tople over when you hit them instead. For the driving stages, the cars have collision that cause you to recoil away from them. There's an additional pully added around the area you acquire the air necklace in Aquatic Mine. The missle part in Metal Harbor is more difficult in this prototype. If you restart after dying on a treasure hunting stage, the emerald locations don't change. The debug menu can be navigated using the analog stick. Press START on Controller 3 while in a Chao Garden to bring up an extensive debug menu. Press Y while the game is paused to display player coordinates. Hold down X while the game is paused to display memory info. There are some debugging features enabled in this build:. In the final, it only mentions the availability of a 'secret' stage, which is Green Hill Zone.
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. However, Green Hill Zone is present in the game and is playable. While it's possible to get 180 emblems in the prototype, Green Hill Zone cannot be activated. The tutorial menus are barely translated and are very broken. All the DLC themes are included and enabled by default. While the English translation is complete, there are various grammar/spelling mistakes throughout the script that still have yet to be corrected. It will load but it won't match the progress you made in the retail version.
The final retail release's saved game is not compatible with this prototype. The sound effect cue during the opening cutscene before the title screen is slightly different. This build contains all the content from the main game and hasn't been truncated for demo purposes. Built almost a month before the final retail versions.
