SpiraDisc Prolog Address

["Bryan Parkoff" <BParkoff@satx.rr.com>]

    Is it true that all SpiraDisc always start at ProLog Address: D5 AA 96
on track $0 and sector $0?  It is because $C600-C6FF PROM is programmed to
start at ProLog Address: D5 AA 96.  After reading track $0 and sector $0,
6502 assembly code instructs to read at a half or quarter track and/or read
at a different ProLog Address such as D5 AA 97.
    Is it how it works?  I understand that Copy II Plus has no way to
duplicate SpiraDisc between source and destination unless we have to change
the parameter.  Does it make sense?
    How do privacy know to crack original disk by reading RAM.  All Apple
II+ and later models have vector reset that prevents us from reading RAM
when vector reset erases whole RAM.  We have to use original monitor without
using AutoStart ROM that we can be able to read RAM without using vector
reset.
    Why do privacy prefer to create binary file from RAM while they give up
reading SpiraDisc scheme?  Why can't they try to read SpiraDisc by using
6502 assembly code instead of cracking software?
    It is my concern that some copy-protected games fail while playing.  For
example, the players go to the high level from low level.  It will fail to
load high level game.  I suspect that privacy takes unused sectors from
track to track by putting privacy picture there.  The privacy picture might
overwrite important data that high level is trying to read.  Does it make
sense?
