Poke me on IRC about the Broderbund apple2 stuff; I have a working RWTS18 discferret flux decoder, though it has to be manually hacked to skip the garbage before the first sector at the track gap. I've corresponded with Roland Gustafsson about it, but he didn't have access at the time to the source code used for originally mastering the disks and producing that 'sync hider garbage' used as (and in addition to custom-by-title sector headers) a per-title key.
