Hi, eXo.
I checked the image.
1. It have protection non-cracked, so you need manual to pass it. Privided old underdogs manual will do.
2. I didn't found CD-play from game - but list of tracks on disk hints that it's simply audio, played in external audio player, just as it was guessed. Check it
yourself.
3. Manual could shed light on this mystery - but I wasn't able to locate it. Mentioned underdogs above is from floppy version, while CD completed with "Strategy guide - user manual", as seen for example
there.
