I recently made a (Sonic 3D Blast Sega Saturn) Music replacement.
It has all OGG changes.
You just copy the folder and go to Data> then replace Soundtracks> folder with this folder.
You will get all the music from the Sega Saturn Version of Sonic 3D Blast with some slightly new themes also added in.*

^Here is the new Soundtrack Folder.
I made this because I like this game so very much.*
