Horray
Ive figured it out!!!!!!!!!!!!!!!!!!!!!!!!
i did some research and found out that the version of soniccd that i have is the BETA510 (very rare) the first sonic cd version(i think).
forget using the CD, you have to use the ISO format.
You have to find the soundtrack mp3 files on the internet(make sure that they are for version of the game.if you have the beta, then you need the beta mp3 files)and rename them accordingly.
If your Iso image is named soniccdb.iso then rename the mp3 files soniccdbxx.mp3(xx=track number) (example take track 2 and rename it
SONICCDB02.MP3(IF IT IS A SINGLE DIGIT TRACK THEN MAKE SURE TO PLACE THE "0" INFRONT OF THAT NUMBER)
Once you have renamed them correctly create a folder and name whatever you want to name it and place sonicCDb.iso into that folder place then place all of the renamed MP3 file inside that folder also (the beta version has 32 tracks)
now run Gens and select OPEN ROM and find the directory with the ISO and MP3 files inside them select sonicCDb.iso and click on open
(remember the mp3 files have to be in that folder also for the music to play)
I know this works because i tested it myself with both the beta and the US final versions
