7ea4e116cc Add a warning if the configured sector size doesn't match the one on disk. 2023-03-26 16:25:40 +00:00

9a8fc80220 Massive overhaul of how the physical/logical layout mapping is done, to make it 
more consistent and bidirectional everywhere and just generally better.
Hopefully this fixes that pesky 1581 problem.

339e9cca10 Hopefully actually fix the C64 side issue, this time, by rethinking how the IBM 
encoder/decoder handles side swapping. We want to be able to swap everything,
or just the side bytes.

c63a761ca4 Actually fix the c64 1581 side issue. Turns out the data's not flipped between 
the two sides, only the bit in the sector header...

clause.

d303067deb Massive refactor to work in logical cylinders everywhere. The logical/physical 
mapping is now done at the last stage and should, ideally, be automatic. I'm
sure there are bugs everywhere.

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

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.

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.

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 
both the encoder and decoder.

efa4c933b3 Made the MFM marker byte detection a lot more robust --- prevents false 
positives; it looks like the new sampler is producing a little bit of wobble
which randomly spoofs a marker byte now and again. This prevents this from
happening (so far).

6af80d1e5e Improve some messaging. A data record is always pushed, even if it's empty (to 
help debugging).

04ff31c348 Add a flag to the IBM decoder to tell it to ignore the logical sector IDs (some 
formats don't use these).
