Well, you think I am wrong, that is your opinion. And you think it is Copylock, that doesn't mean it really is.
IFW has reversed and implemented this copy protection inside the CTA analyser, so yes it's a copylock. Anco mostly used this protection on all of its games. On the Atari ST, and the Amiga.
The CTA analyser engine detects exactly when a protection is known. The result here is crystal clear : it's the copylock "Anco", 12 sectors per track, spanned from track 2 to 6. (by the way, the Amiga version of this protection is also called "Copylock Anco". It works the same way).
Pick any games : kick off 2 and all its releases, Tip Off, and most other Anco titles, they use the same scheme.
As I said, I am aware that you (SPS) call this protection as a Copylock variant. But I never seen or heard any evidence that the NFA (strongbits) protection is related to Rob Northern in anyway. If you want to keep arguing I am wrong, please provide some actual evidence.
Well, If IFW has found that it was a copylock variant, then he is right. (it has indeed the NFA, i saw the same thing as you did, but i don't see where it could not be possible coupled with a Copylock).
I wonder why you react like this, do you have any problem with him ?
There are no such confirmation indeed. But you seems to forget what you wrote just a couple of posts above.
I did not forget anything, you can have a disk dump where 3/4 of the disk is good, and the remaining bad. It's not the first time i see that.
But here i have nothing yet to confirm what i see either with aufit and the CTA.
If you have said that the dumps shows noise in a few tracks, that might indicate a possible problem with the disk or the dump, then I would have agreed with you 100%. But you said that something went wrong ... your disk is damaged ... and that that's the reason the write back fails. Which doesn't make any sense at all.
I have already seen a game with this kind of geometry. It was Primal rage on Amiga 1200. The Disk 4 in revision v1.2 has a mastering error, with half the tracks not mastered on side 1. So yes it could be a problem. Since i can't determine yet if the dump is OK or not, i wait for a 3rd dump.
