Thomas Harte	9b64f64db7	Attempted to normalise some style decisions.`	2016-04-24 22:32:24 -04:00
Thomas Harte	884755c560	Ensured the GL context is available when switching Atari 2600 output, and that it locks the output.	2016-04-24 20:56:21 -04:00
Thomas Harte	d221c712b0	Ensured GL context is active when destructing CRTOpenGL.	2016-04-24 20:34:25 -04:00
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	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	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	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	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	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	e617bd2bb3	Turned audio quality up to the maximum, at least for now.	2016-04-06 21:12:22 -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	fb6fb5d948	Switched to two-phase setup to deal with OpenGL scheduling.	2016-03-20 13:50:13 -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	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	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	3ea0d04a1a	-dealloc now blocks until all audio queue buffers are no longer playing.	2016-02-16 21:47:23 -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	7bc5a43c36	Fixed type warning.	2016-02-12 22:30:22 -05:00
Thomas Harte	0527888b15	Endeavoured to ensure safe shutdown.	2016-02-12 22:30:06 -05:00
Thomas Harte	80e7e5e602	Updated to return old behaviour of drawing only upon changes.	2016-02-04 23:05:47 -05:00
Thomas Harte	8bc3f8046d	This endeavours to move everything into the CRT class except the final version of shader building.	2016-02-04 22:57:46 -05:00
Thomas Harte	e0d51408e4	Onward with carrying this through to the bitter end, this at least results in all the appropriate knowledge and call-ins occuring at the CRT.	2016-02-04 22:28:50 -05:00
Thomas Harte	0efe4b312c	Disabled my various bits of rate interchange debugging; improved test for when to call update_display due to a RAM write.	2016-01-21 22:16:52 -05:00
Thomas Harte	de7218cdf0	Added a lot of commenting to the CPU6502 definition, simplifying its construction. Added missing nullability modifier to CSElectron. Fixed bad-habit Objective-C style naming on the Electron's Interrupt enum.	2016-01-20 21:55:38 -05:00
Thomas Harte	e65cd4cf06	Some data is marginally reaching the CPU from the tape.	2016-01-19 22:05:34 -05:00
Thomas Harte	956b90e203	Attempted further to improve latency; added view adjustment for non-4:3 output aspect ratios. The 4:3 is currently hardcoded, so further work will be required.	2016-01-18 23:55:52 -05:00
Thomas Harte	90eef1df74	Tightened to provide lower latency audio, hopefully.	2016-01-18 20:01:06 -06:00
Thomas Harte	03f683d588	Gave the audio queue something a lot like a spin lock on waiting to pipe out audio.	2016-01-18 19:57:18 -06:00
Thomas Harte	5a39e42413	Wired up enough such that some basic attempt at parsing a UEF occurs.`	2016-01-18 17:06:09 -06:00
Thomas Harte	2779f0e569	Statred working on support for at least the most fundamental file format.	2016-01-18 15:46:41 -06:00
Thomas Harte	b70fdc2de8	Switched to being explicitly careful about not wrapping around and stomping on data not yet output.	2016-01-18 13:56:20 -06:00
Thomas Harte	ddcc34740b	Added lots of debugging output while I attempt to locate the source of audio scratchiness, also simplified manner of dealing with wraparound within the AudioQueue wrapper.	2016-01-18 13:50:19 -06:00
Thomas Harte	781249acf7	Fixed crash.	2016-01-14 20:35:36 -05:00
Thomas Harte	38ffcaa262	Here, at last, is _some_ audio output, at least.	2016-01-14 20:33:22 -05:00
Thomas Harte	afde8dac49	Closed the loop such that audio manages to bubble up into Objective-C.	2016-01-13 22:38:59 -05:00
Thomas Harte	d9a7ef9e46	Edging towards audio output; the speaker is given appropriate input and output rates, and then updated with current divider and enabled/disabled status.	2016-01-13 21:03:43 -05:00
Thomas Harte	d28abdc037	Made an attempt at correct timing, adding support for additional paged ROMs, added file association for .rom.	2016-01-12 22:34:26 -05:00
Thomas Harte	3437781abd	Started sketching out an interface for sound generation. Which made me realise that the CRT in CRTDelegate was redundant, since C++ has namespaces.	2016-01-12 16:54:09 -05:00
Thomas Harte	49a36ec9ac	Added F12 as break.	2016-01-11 22:35:52 -05:00
Thomas Harte	e93dbdb463	Implemented keyboard input.	2016-01-11 19:48:31 -05:00
Thomas Harte	ce916ebd6a	Fixed runaway frame generator.	2016-01-10 23:32:57 -05:00
Thomas Harte	b4f31edea3	Made an attempt to get RGB output mode up and running, and showing at least a box where pixels would be.	2016-01-09 21:32:56 -05:00
Thomas Harte	716bb3281b	This at least now connects up a CRT, though it never talks to it.	2016-01-07 22:26:49 -05:00
Thomas Harte	47a7654c00	Added just enough that this is probably a successful boot. I guess I'm going to need to get invested in graphics next? Hmmm.	2016-01-07 21:01:13 -05:00
Thomas Harte	0db8938d27	Added the option for the CSCathodeRayView to show only a subsection of the full scan area. Zoomed in a little on the 2600. Put in enough piping to give the Electron sight of its ROMs at least.	2016-01-06 23:14:36 -05:00
Thomas Harte	616dc0b57c	Okay, so this is the absolute bare minimum about of refactoring and wiring necessary to get the [unimplemented] Electron machine pumping.	2016-01-04 23:40:43 -05:00
