Factors out paging, implements a bit more of the BD500.
...
That is, enough seemingly fully to work, if I force the drive to report ready.

Makes Jasmin autoboot optional, adds a Jasmin reset key, adds the Jasmin to File -> New... .
...
Also finally implements KeyNMI.

Fixed: the issue was failing to propagate motor control.
...
Also it seems to be incorrect to have the Jasmin paged at initial boot.

Thomas Harte
533729638c
It seems like Jasmin paged in at boot, and button = page back in and reset works?
...
At least, that gets me a 'boot failed' error. Which is something.
2020-01-05 20:34:15 -05:00

Attempts to implement most of a Jasmin disk interface.
...
With one obvious omission: there's no way to start it? The real interface had a dedicated button, but I don't yet know what that button did. Research needed.

Standardises on read and write for bus accesses.

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

Adds Joystick key code mode, ensures events aren't posted in interrogation mode.

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.

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.

i.e. not the one heading back to the CPU.

Sadly receding it by 3 did not have the effect I was hoping for, of receding Enchanted Land's first register tweaking.

Rejigs the video stream to ensure shifter really is continuous.
...
... and definitively to avoid potential buffer overruns. Or, at least, to have a mechanism in place definitively to avoid them. Which will be tested and debugged as necessary.
Also simplifies the colour burst and border/pixels selection logic.

It's inaccurrate to call this _the_ shifter. So don't.
