There are currently three main buffers:
- $4000..$77FF: RAW data of a "phase"
- $7800..$93FF: nibble data of that "phase" after analyzis
- $9400..$AFFF: sync info data (records whether nibbles are 32 or 40
cycle ones)

There first two are mandatory, the last one may be discarded (to be
validated) if the image is transferred by serial/ethernet or cassette
port.

I will create a copy of the source and work on a simple extractor:
- one entry point,
- flexible buffers,
- first track, last track and step numbers,
- slot and drive numbers,
- synchronization flag (really necessary ?)
- nibble count flag (really necessary ?)
...and I will send it to you.

IIRC, you like Merlin ;-)
