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
Thomas Harte	43ab8bbad5	Okay, so then here's a first shot at the Objective-C -> C++ bridge for the Electron.	2016-01-04 23:16:37 -05:00
Thomas Harte	ab45c1d530	Started working on a shell for the Electron emulation, including factoring out the common CRT delegate -> Objective-C bridging, serial dispatch queue and frameskipping logic from the Atari 2600 shell.	2016-01-04 23:12:47 -05:00
