Updated first post with video with a lot of great information on it. I was wrong in thinking the CD32X games would work, but that's fine. Like I said before, there were only a handful. 32X works, but you still need to attach it to the Genesis.
Some things I'd like to reiterate/point out from the video: there's some cool info about the PCM and CDDA audio. PCM seems a bit cleaner than the original, but that also makes the "popping" noise a bit more pronounced, while the CD tracks seem to sound a bit cleaner (at least to my ears) on the Sega CD rather than the MegaSD. If y'all want to listen, check the video out with headphones. I guess it's good to note that a lot of the ISOs would need .mp3s to run together in order for them to work, and .mp3s aren't always gonna sound as clean as audio coming from a CD. So this can just be a problem with the differences in media (bitrates, compression, lossless blah blah, etc), rather than the hardware running the media.
Also mentioned in the video, I'd like to point out that Virtua Racing does not work on it despite the shell being modeled after it. lol
