Within the Sonic Spinball BETA there are a lot of small sound effects which do not make the final game, or are only half complete in this version.

Intro.mp3 - When Sonic & Tails fly across the screen their Aeroplanes noises are unfinished, without the sparkle sound following them.

Fallinwater.mp3 - When Sonic falls in the water during the intro, a different fanfare is heard, and sound very tinny.

Spindash.mp3 - Sonic's spindash is different in this version, and doesn't continually speed up.

Getemerald.mp3 - The soundbyte for this is shorter than in the final game.

Getlastemerald.mp3 - The same fanfare from the final game, but it becomes garbled since the background music plays along with it.
