The music that plays in Sonic's cutscene starts as he jumps out of the helicopter, much like in The Trial.A likely reason for the change is that cutscenes fail to load if the texture file is too big. Like The Trial, texture files for cutscenes are in one uncompressed PVM rather than set of two PRS files.This does not happen with the Japanese voices. Each cutscene uses the wrong voice clips, as the English voice tracks were not fully implemented yet.The scenes themselves differ from the final game's in many small ways:

Under the game's logo, is added, there is a glow effect behind the logo not present in the final and the text in the bottom left corner is slightly different. The title screen is very close to the one used in the final game. This version is dated Ma3 months before the game's release. The demo includes a level for each character, as well as 2-Player Mode for each type of gameplay. Sonic Adventure 2: Preview is a demo of Sonic Adventure 2 that was sent to the press in order to gain publicity for the game. There's also a few screenshots needed, particularly for showcasing the main menu and early timestamps. There's more object layout differences in the stages.
