Switched to clocking the 6522 by the half-cycle. Very trivial test now passes.

Started endeavouring to sketch out the boilerplate for writing a 6522 test harness. Added a default implementation of synchronise to the 6522 too, since not everybody is going to want one.

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.

Increased buffering range of audio as a quick fix for now. Basically means: increased latency as a short-term fix.

Hacked my 6522 to work. Mistake is in not returning output as input when appropriate — i.e. that I'm ignoring data direction. Also fixed K and L keys.

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.

Added forwarding of a loaded PRG from the Swift document to the wrapper. So I think that possibly completes the Swift side of things?

System ROMs are now supplied to the Vic-20 wrapper, though they stop there. I also factored key forwarding out of the ElectronDocument and into the superclass, depending upon the child conforming to CSKeyboardMachine.

Back to asynchronous updates and drawing, to try to improve guarantees on audio latency; experimenting with whether other parts of the approach are fundamentally flawed; added a broad-phase for scheduled updates on the 2600.

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. Added a method to ask it what a good output frequency would be.
