Some time ago I downloaded all my soundtracks available from my purchased games on GOG.com, and I noticed that got 3 items from Duke Nukem:

Both titles had a link to "duke_sms_tones" (with 113 tracks) and one of these titles had another link to "SMS_tunes" (with 30 different tracks).

Now I noticed that this SMS_tunes option isn't available on any of both Duke Nukem titles... what's happened?

I just need to know from what game that tracks came from, to rename my "sms_folder" correctly and catalog in my music library.
but... it's apreciated too that this sms tones pack comes back on game extras for future download =)

Thanks

Are you sure you got the second one from gog? I don't recall if there was ever another pack here.
