Well, I've analyzed it tonight and Bounty Bob definitely uses true halftrack protection. I rewrote n2g and got halftrack support working properly and it now loads further than it did before. It reads about 4 segments, then moves to track 1.5 and then freezes. The disk appears to be mastered such that 1/2 of the track is written out, then the head is stepped out one halftrack and the other 1/2 is written, etc. This is similar to the "Spiradisk" protection on the Apple ][, just not quite as extreme (the Apple could do quarter-tracks). So we're getting somewhere for use in emulators, anyway. It can't be copied without a completely custom routine. |
