Thomas Harte	929cfc49cb	Extended window for picking output frequency, attempted to consolidate CRT OpenGL timing uniforms for approprate resetting.	2016-04-24 18:58:31 -04:00
Thomas Harte	082003ed0a	Reintroduced the CRT delegate and the 2600's automatic region switching. Albeit that the CRT itself doesn't adjust properly to new timings yet.	2016-04-24 18:36:22 -04:00
Thomas Harte	80a3169674	Started reviving the Atari 2600 emulation. Put new startup sequence into place.	2016-04-24 06:56:08 -04:00
Thomas Harte	9c89b668ae	Made further attempts to improve synchronisation and interrelated timing between display and machine update.	2016-04-20 22:35:46 -04:00
Thomas Harte	7aa87723a9	Added: key states are all cleared if the window loses focus. Which resolves sticky key issues. Allowing me just to use command+option+O for options and map both command and option as FUNC.	2016-04-19 21:29:10 -04:00
Thomas Harte	d5bac2f04f	Spotted error was in texture target all along. This now gets as far as showing something a lot like the correct display, but precision is way off. Way off.	2016-04-18 21:32:48 -04:00
Thomas Harte	86626bbd72	Switched key that maps to FUNC from command to option. Logic is that command may frequently be used for performing an action which changes the key window, in which case we won't realise if it is released.	2016-04-18 19:20:26 -04:00
Thomas Harte	f89308e913	Set the 'options' windows to hide on application deactivation so that they don't cluelessly sit on top of the rest of the system.	2016-04-18 19:14:58 -04:00
Thomas Harte	bf29c8e2bf	Fixed mismatch in television/monitor selection, ticked view for drawing concurrently, since it can, removed stray space.	2016-04-18 19:01:15 -04:00
Thomas Harte	3d53f157de	Output selection now takes effect. So I can stop accidentally committing changes back and forth.	2016-04-18 08:27:58 -04:00
Thomas Harte	94f148e212	Wired in options, at least getting as far as the Objective-C bridge. Then fast loading makes it to the emulated machine, display output type doesn't.	2016-04-18 08:21:00 -04:00
Thomas Harte	6158275ea7	Started adding an options panel.	2016-04-17 21:43:39 -04:00
Thomas Harte	499f7ace07	Re-enabled working video output for the Electron for the day and consolidated the rough metric I'm using to pick a number of taps for the audio filter.	2016-04-17 20:43:20 -04:00
Thomas Harte	104f44f27f	Attempted to improve deinterlacing, gave the CRT full control over blend mode, switched back to 2000000Mhz audio.	2016-04-14 22:20:47 -04:00
Thomas Harte	2cc72169ff	Ensured machines can nominate their own aspect ratio windows. Switched to 11/10 for the Electron.	2016-04-11 23:12:56 -04:00
Thomas Harte	7276a06cc0	Added a helper to calculate a visible rect based on output timings, used it to scale the Electron output up to the full window size.	2016-04-11 21:47:23 -04:00
Thomas Harte	e617bd2bb3	Turned audio quality up to the maximum, at least for now.	2016-04-06 21:12:22 -04:00
Thomas Harte	28e6517234	Switched away from tracking absolute time to tracking relative.	2016-04-06 20:46:00 -04:00
Thomas Harte	d4be4c4769	Of course, I want min. Not max.	2016-04-06 20:27:48 -04:00
Thomas Harte	fd1f6a7e1f	Expanded on thinking.	2016-04-06 19:35:53 -04:00
Thomas Harte	e885438363	The penny has finally dropped that I can drive the CPU stuff in a manner completely decoupled from the GPU stuff. For much improved parallelisation.	2016-04-06 19:34:34 -04:00
Thomas Harte	4595741ab0	Made an attempt not to interrupt the display link queue too much when emulation is running slowly.	2016-04-04 20:22:33 -04:00
Thomas Harte	3038704977	Attempted to introduce a lowpass filter to the graphics output, reverted 6502 optimisations as seemingly not working.	2016-03-21 22:01:25 -04:00
Thomas Harte	5966ac845f	Switched symbols and updated all-RAM 6502 in order to fix unit test target.	2016-03-20 22:48:56 -04:00
Thomas Harte	902017a962	Fixes: drop any processing backlog, try not to allow an Electron document to close mid-draw, perform a frame grab even if the emulated machine is over-processing, really really don't create a CRT until it's safe.	2016-03-20 18:42:37 -04:00
Thomas Harte	fb6fb5d948	Switched to two-phase setup to deal with OpenGL scheduling.	2016-03-20 13:50:13 -04:00
Thomas Harte	eabc382540	Fixed: of course I can't rely on the pointer to CVTimeStamp not becoming dangling during a queue jump.	2016-03-19 23:02:42 -04:00
Thomas Harte	4c5d66c317	Made sure GL context isn't activated until it's locked.	2016-03-19 22:54:56 -04:00
Thomas Harte	a546277f88	Added the simplest mechanism to decouple emulation from the display link queue.	2016-03-19 22:53:37 -04:00
Thomas Harte	9da7716c72	Attempted to simplify threading, thereby allowing machines to be constructed within a valid GL context, and started adding appropriate GL syncs. Which all oddly drops everything to a negligible FPS. Investigation will follow.	2016-03-19 22:46:17 -04:00
Thomas Harte	4ac1f959e9	A shortcut here and a shortcut there; this allows me at least to determine whether use of a PBO gains anything.	2016-03-19 17:07:05 -04:00
Thomas Harte	4cd0aa3416	Completed FIR filter based audio output.	2016-03-15 23:37:35 -04:00
Thomas Harte	7694297c83	Introduced an adapted version of the previous Clock Signal's FIR filter.	2016-03-15 21:05:20 -04:00
Thomas Harte	1c4acfb599	I think this is a prima facie acceptable implementation of the fast tape hack.	2016-03-13 17:39:53 -04:00
Thomas Harte	bb0cd89574	Got explicit about threading guarantees.	2016-03-13 13:38:03 -04:00
Thomas Harte	cfa616d593	Fixed: timing issue versus supplied test ROM was failure to include the Plus 1 ROM in the mix.	2016-03-12 11:51:20 -05:00
Thomas Harte	bf5747f83e	Made an attempt to chop out all the stuff of building up the OpenGL data from the stuff of parsing input.	2016-03-08 22:40:23 -05:00
Thomas Harte	14b2927275	Made further attempts to tidy up; trying to demarcate between public interface and private.	2016-03-08 20:59:16 -05:00
Thomas Harte	1e5fe2b2c1	Made an attempt to reestablish the Atari 2600 output connection despite various changes (TODO: generalise that stuff), and to start creating the composite shader.	2016-03-07 21:04:04 -05:00
Thomas Harte	41c09f8c3f	Renamed CSCathodeRayView to CSOpenGLView as it no longer has any CRT-related responsibilities. It just does the GL and manages a serial dispatch queue.	2016-03-05 14:45:09 -05:00
Thomas Harte	95efeb1d56	Ensured all delegate and responder delegate messages occur on the same queue.	2016-03-05 14:35:47 -05:00
Thomas Harte	c754a6e45a	Decoupled execution speed and frame rate; cleaned up.	2016-03-03 22:12:31 -05:00
Thomas Harte	60d35fa72b	Requested multisampling, if available, rather than supersampling.	2016-02-27 22:46:31 -05:00
Thomas Harte	c7f54d649e	Switched back down to two samples per pixel. Though one might do it. Need to investigate.	2016-02-18 23:21:25 -05:00
Thomas Harte	3ea0d04a1a	-dealloc now blocks until all audio queue buffers are no longer playing.	2016-02-16 21:47:23 -05:00
Thomas Harte	bbffbb5dc2	Resolved deadlock if an invalidate call was sent to the Electron while it was in the middle of an update.	2016-02-16 20:35:45 -05:00
Thomas Harte	a01f90ff3e	Attempted a switch to the real PAL visible area and to something a bit like a real phosphor decay.	2016-02-14 21:57:23 -05:00
Thomas Harte	7580d192d5	Fixes: now setting correct frame time estimate, properly enabling the timestamp attribute, and ensuring that the Electron flushes screen work at least once per host frame update.	2016-02-14 19:28:02 -05:00
Thomas Harte	eeb0e134fd	Started the transition towards a more natural collection of rolling buffers, with phosphor decay in mind.	2016-02-13 20:52:23 -05:00
Thomas Harte	7bc5a43c36	Fixed type warning.	2016-02-12 22:30:22 -05:00
