As I mentioned earlier at the moment the only emulator that will run the game is Ages. However, there are some other projects that may run it in the future.
RetroDrive currently emulates 32X and Genesis/Megadrive. The author Tim Meekins mentioned that he was working on getting Sega CD/Mega CD to work. The emulator page is located here
Sega Emu is also an multi-sega-emulator in the works. The page is here.
VGen is another Sega Genesis/Sega CD emulator in progress. The page is here
