Extended analysis to spot IRQ and NMI vector changes, for titles that simply adjust those then exit. Ensured Oric emulator can type and load quickly on an Oric 1 just as well as on an Atmos.

The emulated Oric now has access to both versions of the BASIC ROM and picks between them based on the static analyser's recommendation.

Moved audio work back into its own thread, but this time it queues up an all happens only upon a flush. Hopefully to resolve synchronisation cost concerns.

Switched the Oric implementation simply to rely upon the Storage-level tape parser. So now there's only one, authoritative one of those.

Made a few mapping fixes, clarified where the default reset code lives, ensured the Oric and Vic clear their keys when the typer ends.

Made the typer much more able to help out, and thereby tidied and separated the Oric's typer.

Implemented typer for the Oric, and I'm starting to think the code is a bit too repetitious. Refactoring will be forthcoming. Added CLOAD"" as the loading command for all Oric software.

This appears to be it. The secret? Don't worry about the stop bits. They're just processing time. Latch onto the next start.

This is an initial attempt at reading actual tape data. It loses sync though.

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

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.

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