Thomas Harte	3b71d1a309	Switched to a variable-length buffer based on attempting to hit approximately a certain quality of service.	2016-06-16 21:35:22 -04:00
Thomas Harte	2ee78d42b9	Made an attempt also to trigger updates upon audio packets being returned, and significantly to reduce the size and quantity of those. This should get down to 11ms latency if the output wave is 44100; I might need to scale up the buffer size as the sampling rate increases or this is going to get crazy at 192Khz.	2016-06-16 20:51:35 -04:00
Thomas Harte	00a9f1bf24	Fixed best-effort updater actually to run, finally moved clock rate announcement into the C++ side of things, started working on a mechanism to allow clock rate to be updated.	2016-06-16 20:39:46 -04:00
Thomas Harte	1921a6c469	Rewired the existing cause-an-update route from the OpenGLView through the best-effort updater.	2016-06-16 18:19:23 -04:00
Thomas Harte	e0baaf17f1	Added class prefix.	2016-06-15 08:07:25 -04:00
Thomas Harte	0b221e773f	Fixed ROM naming and sizes, ensured machines without sound outputs don't end up with an audio queue.	2016-06-05 11:20:05 -04:00
Thomas Harte	b29b2a5d08	Added forwarding of a loaded PRG from the Swift document to the wrapper. So I think that possibly completes the Swift side of things?	2016-06-05 09:01:32 -04:00
Thomas Harte	8052ce9223	System ROMs are now supplied to the Vic-20 wrapper, though they stop there. I also factored key forwarding out of the ElectronDocument and into the superclass, depending upon the child conforming to CSKeyboardMachine.	2016-06-05 08:53:05 -04:00
Thomas Harte	363e14a92f	Reorganised system ROMs out of the Mac-specific folder, adjusted Mac code to expect to find them organised hierarchically (as how many os.roms am I going to have?) and added readme files to explain what's missing from the Git repository.	2016-06-05 08:33:01 -04:00
Thomas Harte	06e1db8c85	This now gets as far as missing selectors.	2016-06-04 21:49:03 -04:00
Thomas Harte	404873fe58	Started sketching out infrastructure for Vic-20 support.	2016-06-04 21:43:50 -04:00
Thomas Harte	68a8851c52	Increased parallelism, allowing a simplification in the GL view.	2016-06-02 22:29:09 -04:00
Thomas Harte	8623dc2833	Consolidated a little more within the common code, adding sampling rate selection based on querying the machine.	2016-06-01 19:04:07 -04:00
Thomas Harte	50543e9676	Minor factoring up: the audio queue is now pushed universally by MachineDocument.	2016-05-31 22:36:53 -04:00
Thomas Harte	c773c3a66c	Started trying to clean up and consolidate on the Swift side of things but time is up for the day.	2016-05-31 22:32:38 -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	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	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	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	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	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	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	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	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	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	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	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	0527888b15	Endeavoured to ensure safe shutdown.	2016-02-12 22:30:06 -05:00
Thomas Harte	b5bcadb8d3	Reinstated clipped CRT output, with more appropriate ownership of the decision.	2016-02-07 22:18:55 -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	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	4554abb755	Made an attempt to be more rigorous in display generation on the Electron, to make sure I deal with mid-line changes to/from blank line mode. Even if it turns out that they generate pixels.	2016-01-29 21:14:13 -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	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	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	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	650077feac	Pulled a few things out as constants, zoomed in a little. Still in a 4:3 window though.	2016-01-11 22:18:34 -05:00
Thomas Harte	e93dbdb463	Implemented keyboard input.	2016-01-11 19:48:31 -05:00
Thomas Harte	a900bfed65	Fixed to ensure that frame rendering wraps around, and to properly connect the Electron to its view. Now I need a working pixel shader.	2016-01-09 20:34:22 -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	c69b3256ba	Slightly simplified Swift usage.	2016-01-04 23:44:36 -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
