8cbef669b1 northstar: Fix after decoder change. 
Recent changes to the decoders broke North Star.

d69944dd8c Micropolis: Add support for MZOS checksum. 
Vector MZOS uses a different sector checksum than the standard
Micropolis checksum used by MDOS, CP/M and OASIS.  Automatically
detect the checksum on the disk by default, but allow the user
to force the use of a specific checksum using the
--decoder.micropolis.checksum_type parameter.

a25111e411 Micropolis: Improve decode. 
* Discard a partial sector at the end of the track.
    * Do not seek to the index mark for the first sector.
    * Use a 64-bit pattern to match the SYNC.
    * If SYNC is found too early, search for a subsequent SYNC.
    * While decoding the sector record, enforce the SYNC pattern
      and track ID.

0d7de7bbc0 Add support for ignoring certain sectors (needed for FastCopy disks on the 
Atari ST).

f6b1d9c493 Fix a regression in the MX decoder. 2022-02-12 23:37:20 +01:00

c539debc84 Fix the Amiga decoder, which got broken with the decoder change. Also fix the 
encoder which was always broken (but Amigas apparently didn't care).

e8d1c90182 Fix, hopefully, the rest of the decoders. 2022-02-12 15:02:42 +01:00
David Given
0933dc1afa Partially complete rework of all the decoders to avoid seeking inside the 
fluxmap. This requires resetting the FluxDecoder, which loses any pending
state, resulting in bad reads for (some) formats which don't have gaps between
sectors --- the DVK MX is the main victim.

89688394f8 Replace the upgradefluxfile builtin with a seperate upgrade-flux-file tool. 
This allows us to remove all the SQL stuff from the main program, and restores
the ability to upgrade from version 2 SQL files.

b15fd05e8d Add support in the IBM decoder for trackdata protos, and then configure the IBM 
profiles to know about which sectors it should see in the result image to allow
retries if sectors aren't found.

3d1ee7a43e Don't spin in an infinite loop if the decoder tries to find a data record and 
the matcher fails to find anything, leaving the seek point unchanged.

18d90c44dd Rework the flux decoders to add a desync opcode for separating multiple reads 
in a flux stream. Finally add a unit test for the flux decoder.

ce5fcaf172 Micropolis raw 275 byte sectors 
These are used by formats like VGI since the ECC varied per machine and
the 10 extra bytes of user data may contain useful information.

29e8c99b4f Hopefully get the imagereader/imagewriter and IBM encoder/decoders using sector 
IDs.

8b115f8156 Convert the IBM encoder/decoder to use lists of sector IDs rather than 
sector_skew strings.

c087539eb7 swap_sides isn't symmetrical for the encoder and the decoder. On the encoder, 
it affects which logical side is being written to which physical side. On the
decoder, it modifies the logical side bit in the sector header itself.

786b35fee2 Fix swap_sides on the ibm encoder/decoder to work; remember to specify it for
