Here is how you play Sonic 3D Blast on a Windows PC.
I will include links
(I use a Windows 10)
Get a copy of Sonic 3D Blast.
Make a Folder named "Sonic3D", it should be in C:\Sega (If you dont have C:\Sega, make the Folder "Sega" in C:)
Open SegaPCReloaded (It should be included in the Sonic 3D Blast Files in the download link below) and click install then click on Sonic 3D Blast, then click on Existing Files, then go to Sonic3D, and Select that Folder.
Then Rename the File "Music" to "MUSIC".
Get bass.dll and add it to Sonic3D.
If it is Done right, it should work.
Enjoy!
