 2020-01-29 22:18:41 -05:00
Thomas Harte 0e29c6b0ab On further reflection, I think events should occur after the running period. 
I'm testing this now for sanity in 2/4bpp mode.
 2020-01-28 23:26:37 -05:00

Thomas Harte 7e8405e68a Makes 72Hz horizontal sync independently relocatable. 
... and moves and shortens it, based on my guesswork as to requirements.
 2020-01-27 23:40:01 -05:00
Thomas Harte c8fd00217d Resolves loss of horizontal resolution in 1bpp mode. 2020-01-27 23:08:28 -05:00
Thomas Harte 9d340599a6 Towards ST 1bpp support: puts vsync in an appropriate location, starts experimenting with proper CRT timings. 2020-01-27 23:00:30 -05:00
Thomas Harte a71c5946f0 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.
 2020-01-21 22:28:25 -05:00
Thomas Harte 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.
 2020-01-20 21:45:10 -05:00

Thomas Harte 42ccf48966 Judging by Pompey Pirates Menu 88, vsync should occur a line earlier, ending during line 0. 2020-01-02 20:16:28 -05:00
Thomas Harte 0a12893d63 Shunts vsync back down to top of frame. 
It's guess after guess, basically.

Simplifies around as possible.
 2019-12-29 21:53:45 -05:00

Thomas Harte 93f6964d8a Introduces some preliminary line length unit tests.

 2019-12-28 22:50:34 -05:00
Thomas Harte 13f11e071a Simplifies border colour change propagation. 
I'm not sure it was even technically correct as was.
 2019-12-28 10:45:10 -05:00

Thomas Harte a9d1f5d925 Pulls out address reload as something I can position independently. 
Sadly receding it by 3 did not have the effect I was hoping for, of receding Enchanted Land's first register tweaking.
 2019-12-27 23:47:19 -05:00
Thomas Harte 2757e5d600 Removes untrue comment. 2019-12-27 22:51:11 -05:00
Thomas Harte 5026de9653 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.
 2019-12-27 22:47:34 -05:00
Thomas Harte 5fa8e046d8 It's inaccurrate to call this _the_ shifter. So don't. 2019-12-27 19:03:10 -05:00
