Completed proof of theory for fast loading. It's just an around-the-back direct-to-file hack for now though.

Ensured emulation doesn't enter an infinite loop if the user attempts to read beyond the end of a tape.

Ensured AY registers aren't rewritten just because of a synchronise event. A stall prior to figuring out proper bus logic, clearly.

Altered phase so that it now merely accounts for accumulated error across a frame. Can probably do better.

Fixed inverse characters, added an extra per-frame phase change, based on empirical observation, ensured header guard won't become ambiguous.

Ensured propagation of synchronise messages, added enough to do plain tone. Probably. So: noise and envelopes missing. And it's all far too quiet.

Made some AY advances; it's now being polled for samples and collecting more information on what it needs to output.

Added a VIA. Now it's time to find out how poor my 6522 emulation is.

Made an almost complete implementation of video. Just one row of the diagnostics cartridge seems to be off, showing thw wrong character set.

Meaningful text! Albeit with the initial 'O' of 'Oric' missing. I guess control codes and NMIs next?

|
Switched to using a diagnostic ROM for now, as it'll definitely boot without initially requiring either a 6522 or AY. Have some forms appearing which imply I'm not doing badly, at least up to not knowing where I'm supposed to get character pixels from.

That's thread safety, subject to the async task queue being made to work...
