I have Gens all set up with bios and all. I downloaded a few ROMs from a website for Sega CD. The files are all zips with the first file called "Game XYZ - Track 1.iso" and all other "Game XYZ - Track N.mp3", replacing "Game XYX" with, for example, Sonic CD and Track N with some number. All the .mp3 tracks are obivously the game's CD-DA sound. The games play fine, the problem is all of the CD sound is not recognized nor played (Probably since they are in files other than the iso). How do I get Gens to receive and play them when apropriate?
