Early	Final

In the early renders, certain characters are wearing their Arks of the Cosmos where they would during gameplay. Amy, Blaze, Cream, and NiGHTS (almost entirely obscured) wear theirs as necklaces/chest ornaments, Shadow wears his as an anklet, Amigo decorates a maraca with it, Silver wears it on his right hip (in the final game, he wears it on his left hip,) and Sonic and Billy Hatcher wear theirs on their wrists.

In the final renders, only Sonic wears an Ark of the Cosmos.

Some characters also have different poses and lightning.

Truncated Menu Music/Early Remix#

The song played in the main menu is what appears to be an instrumental of an early Electro Extended remix of Un-gravitify. The song normally loops, but if the looping is disabled through a specialized audio player capable of playing ADX files (like foobar2000), the song can be heard in full, with a proper ending. Disappointingly, the instrumental of Catch Me If You Can heard in the Options menu simply cuts off if looping is disabled and has no ending to speak of.

Version Differences#

Although the game was released only for Wii in Japan, the US PS2 version's language selection includes both Japanese text and audio. The European PS2 version removes these options.
