Hawkeye c64 strangeness

Hi there.
I'm trying to get a definitive answer on weather hawkeye is protected.
Does anybody know what exactly the protection is looking for when it checks track 35 of the boot side?
I've tried about 4 copies of the game, some have data duplication protection system data on tracks 36 through 41, others just have the data on the last track, and the last one I tested had none at all. None of these versions move the drive heads beyond track 35.
track 35 appears to be empty apart from the normal CBM dos data. I can even run the game from a d64. This is very unlike thalamus to leave any of their earlier games freely copyable.
Thanks.

Track 35 sector 0 contains the directory for the loader, each entry is four bytes long, the last two bytes of each entry are the starting track and sector. The Data Duplication tracks on one of your copies might be leftovers, it might be a recycled disk. I couldn't find anything which indicates a copy protection.

Later Thalamus releases are not protected, can't recall whether Hawkeye has protection or not. If it has, it's checked before the main menu. I think I had at least two different versions...

G'day
Hawkeye has no protection, but armalyte does, and so does retrograde
I seem to recall hearing somewhere that armalyte was released after hawkeye, September 1988, and Retrograde came out some time in 1989.
So for whatever reason, they decided to put protection on some of their 1980s releases, but not all of them.
very odd.

After the first three releases, iirc, then there's Hunter's Moon (December 1987), Hawkeye (August 1988), Armalyte (October 1988), Retrograde (January 1989), Snare (February 1989).

Armalyte definitely wasn't out by the time the PCW show in September 1988 was on, because the Newsfield stand had it on test play but they hadn't published the review yet in Zzap!64. I asked Gordon Houghton what score they'd given it, and he said it was a Gold Medal game.
