I need to get a bit more definitive on naming but this gets all the way to setting a configuration upon an Electron.

Added the minor piece that will allow analysis results to be obtained from Objective-C, and exposed to Swift in sufficient detail for it to be able to pass on to the machine.

Addressed my dithering here: the file format containers themselves should do nothing but inspect the data to find out whether it is of the correct format. The machine steps are there for machine-specific validation. So it's probably easier to treat a binary ROM image just as a binary ROM image. Therefore, the Acorn-specific .rom detection is now in an Acorn-specific area.

Added hacky segue into analysis for all Electron formats. Added analyser to try to differentiate Acorn-format ROMs from other things called .rom, which are likely to be numerous.

ROMs definitely have no behaviour other than responding to memory accesses. Cartridges might. So picked the more general term. Sketched out a class at least to parse PRG as though it were a cartridge. Hence the static analyser can guess at whether a PRG is a cartridge or an ordinary program.

Turning this into a slog: gave UEF a more appropriate name, got as far as now having to decide what to do about ROMs as to structure. I guess they're machine specific, so specific classes?

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?

Made a first stab at having automatic loading be optional. But things are currently arranged such that the machine options are communicated too late to have an effect. So work to do.

With a history of three pulses, this can track up a 10% sine variation in a 1010101 stream. So I guess this'll do for now?

Made an attempt also to trigger updates upon audio packets being returned, and significantly to reduce the size and quantity of those. This should get down to 11ms latency if the output wave is 44100; I might need to scale up the buffer size as the sampling rate increases or this is going to get crazy at 192Khz.

Actually, I'm dithering over whether the 6522 should be an ordinary class or a curiously-recurring template. But it'll need a file, definitely.

Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari.

Made an attempt to be more rigorous in display generation on the Electron, to make sure I deal with mid-line changes to/from blank line mode. Even if it turns out that they generate pixels.

Added a lot of commenting to the CPU6502 definition, simplifying its construction. Added missing nullability modifier to CSElectron. Fixed bad-habit Objective-C style naming on the Electron's Interrupt enum.

Started making first moves towards stripping CSCathodeRayView of its responsibilities. If that can be merely an OpenGL view that presents things, things will be a lot more portable.

Attempted further to improve latency; added view adjustment for non-4:3 output aspect ratios. The 4:3 is currently hardcoded, so further work will be required.

You now get an Electron only if you ask for a new file. That'll do for now while it's the only thing that one might want to start without supplying a file. The 6502 now starts from a defined point — being reset. The Electron is starting to grow the absolute most simple buds of its memory map.
