Shifted ownership of PETSCII -> string conversion down to the storage layer, where it's useful for tape parsing.

Started relocating the tape parsers down from static analyser to storage, to signify that they may be used by the emulation (if fast loading is supported on that machine).

The parsers no longer own a tape, merely taking one as an argument. So they can be an adjunct.

Factored out Commodore is-a-ROM test, allowing it to be used from the Commodore analyser and thereby allowing ROMs to get as far as the machine again.

Made a first stab at enabling multi-disk machines and thereby obeying (some of) the Plus 3's status register.

Renamed class, intending to turn a Disk::Drive into literally just that, and have a thing with a PLL that consumes events be a Controller.

With minor cleaning, this should now do Commodore disks correctly (?)

The Commodore analyser now at least hands off to somebody else a chance to parse disks.

Made yet another guess at Commodore analysis. Elevated fast tape-related unnatural speed up to the OS-side mechanisms.

Implemented seeking on tapes, mucked about a bit more with the Commodore analyser, at least temporarily removed cropping from the Vic emulator.

Sought to be more intelligent in handling cases where the two parts of a header or data field don't match — if either looks good then use it in isolation.

The error flag is no longer directly exposed. I also tweaked the Commodore import numbers just a touch. But I think I need proper calibration.

Added reminder, ensured the couldn't-find-data case doesn't cause a crash. Though it should imply some manual investigation.

Added logic to try to spot when the first program is BASIC and, if so, what the correct memory model is, then to get that information to the Vic. Though it currently then gets overwritten by the view controller. Grrrr.

Pulled the strands together provisionally to complete Commodore ROM-format tape parsing. Things are going to get complicated if or when I need to tackle turbo loaders.
