Starts a switch to reflectable-style runtime options.
...
The Amstrad CPC and ZX80/81 have made the jump so far, subject to caveats. The macOS build is unlikely currently to work properly.

Attempts to pull drive ownership into DiskController.

On further reflection, I think events should occur after the running period.
...
I'm testing this now for sanity in 2/4bpp mode.

All these 'override's can be 'final's.
...
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

Removes audio_queue_.flush() calls; I don't think I really need to block. At least, not usually.

Ensures proper manipulation of scan_statuses, leading to the correct result out of a CRTMachine.
...
Possibly with the exception of the TMS, as I appear to have uncovered an unrelated issue there.

d97a073d1b
Adds the necessary routine for all machines to be able to respond to get_scan_status.
...
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.

Standardises on read and write for bus accesses.

Logic being: name these things for the bus action they model, not the effect they have.

This should fix Turrican due to the latter change; I'm not aware of software that uses the former.

Judging by Pompey Pirates Menu 88, vsync should occur a line earlier, ending during line 0.

Thomas Harte

Switches to latching video interrupts until acknowledged.
...
Seems to fix Cisco Heat, at least. I have no idea whether I'm latching the correct thing, whether IACK should clear both or only one, etc.
