Simply. Just mount your CD/ISO at basic mounting level. Then run install.exe and that's it. Music, voices, sound effects - everything is running perfectly. Shadow of the comet doesn't demand high CPU cycles.

Ok, this is ideal situation. If you are trying to run some rip, there might be problems. I don't know, I have not tried it, since I possess full CD version.

I can also say that floppy version works ok.
