Made minor fix to ensure that a header that appears to extend beyond the end of an Oric .TAP doesn't create an ostensibly endless tape.

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.

Fixed off-by-one recording of disasssmbled addresses; added logic to the Oric static analyser to try to guess between BASIC 1.1 (the preferred option in a tie-break or if no information is found) and BASIC 1.0.

In theory that's a full disassembler, at least as far as I want to go for now. Time to test.

Started fleshing this out; addressing modes are completely decoded, along with a bunch of opcodes, but appropriate address advancement isn't in yet, and neither is filling in derived metadata.

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.

I am instructed that the Oric actually catches only positive transitions, and compares the distance between those to a threshold. So here's an altered version of the tape parser that does that.

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

Implemented better sync-to-zero and discovered a header counting bug plus, probably, a misleading representation of gaps in the Oric TAP decoder.

The parsers no longer own a tape, merely taking one as an argument. So they can be an adjunct.
