Dragged multibyte primitives and signature checks up to the base class. Implemented support for Oric MFM-style .DSK, at the file format level.

Created a base class for the boilerplate fopen stuff, switched as many classes as possible to its use, switched to postfix underscores and non-camelCase names.

Ensured tape-formatted PRGs reach a conclusion.

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

Made a quick first attempt at getting a file name from Acorn tape, failing terribly but at least formalising tapes being able to signal their end.

This has now successfully loaded its first PRG-as-a-tape.

Adopted header/header/data/data pattern. But still not complete joy.

This gets through loading the first(/only?) copy. I tried repeating it with a bit-flipped header, now I'm trying repeating the header with a different file type. More documentation searching to do, I guess.

Fixed parity: now calculated from the actual byte and works the other way around. The Vic now believes it is loading the actual program. So I guess bytes, headers and the lead-in is working.

This proves that bytes are being deposited properly. For the first 36 anyway, and with no announcement.

Lengths I'd taken seem to have been for dipoles, not single poles. So I just doubled the clock rate. Also I was producing each dipole as high then low, when they should probably be low then high. The Vic now at least recognises that something is happening on the tape.

I've obviously misunderstood something as, as far as I'm concerned, this should at least get me a 'LOADING'.

I'm starting to make a little headway, I think: this performs lead-ins and countdowns, though with no actual data or anything as helpful as that.

This likely forms the Commodore dipoles correctly. It just stays stuck in leader tone forever is all.

Made sufficient changes for the Vic itself to believe it can recast a PRG as a tape and insert it that way. So now the ball is in the court of: how the heck are Commodore tapes encoded?
