So, how is the reframing handled in software? Is there a loop that scans the data for 8 different shifted versions of the sync, then shifts all the data enough bits to reframe them?

Greetings.
I bought a copy of La_Crackdown off Ebay which supposedly uses vorpal-newer.
I dumped it with nibtools and loaded it up in winvice sps and to my utter amazement, the game actually worked, Nibtools just seems to dump the so-called "syncless" tracks with ease.
My setup is a a machine with windows xp sp3, open cbm 0.4.99.93 built sept 2011, an original 1541, a Parallel port using the xap1541 setup, and multiple versions of nibtools.
I used mnib 0.45.1 for the dumping of this title because I find it dumps some protections better than others.

Just got hold of a copy of Legend of blacksilver and all I can say is... wow. No wonder it's impossible to dump with nibtools. when I examined the troublesome track 2, I counted only 4 or 5 sync marks throughout the entire track.
The fewer sync marks there are, the more difficult the track is to nibble.
La Crackdown is one of those hit&miss titles. Most times you'll get a good read of the disk, but no such luck with Blacksilver.
