Now that the game's successfully been dumped, there's an NSF rip of NTDEC's "War In The Gulf" out there now on Gil Galad's site. You can find it in the 03-03-2011 pack (which he's mislabeled as 03-03-2010) on
his news page.
Anyway... Check out the seventh song in it (tune #6, for players that start counting at 0).
Why, yes, that is indeed a chiptune version of the Scorpions' "Rock You Like A Hurricane". It's... surprisingly recognizable, actually.
Now I'm wondering whether any of the other tunes are classic heavy metal tunes I'm not recognizing. They sure sound like they ought to be, and several of them sound incredibly familiar but I can't place them.
