Thomas Harte	167ed9b8bb	Added enough to load a PRG as a ROM.	2016-06-11 14:00:12 -04:00
Thomas Harte	d9b001d3fc	Minor clean-ups.	2016-06-11 13:51:04 -04:00
Thomas Harte	3e8d383615	Improved key map. Possibly enough to type some basic BASIC?	2016-06-11 13:19:59 -04:00
Thomas Harte	d1731b1d26	Hacked my 6522 to work. Mistake is in not returning output as input when appropriate — i.e. that I'm ignoring data direction. Also fixed K and L keys.	2016-06-11 13:06:01 -04:00
Thomas Harte	271de23ee6	Ran on in and introduced a bunch more keys, hopefully to help to diagnose.	2016-06-11 12:26:19 -04:00
Thomas Harte	d7c1f5b18a	Made an attempt at hooking up the '2' and '4' keys. A mostly unsuccessful attempt. 2 does nothing, 4 clears the screen.	2016-06-11 11:50:37 -04:00
Thomas Harte	6522530e1c	Actually, I'm dithering over whether the 6522 should be an ordinary class or a curiously-recurring template. But it'll need a file, definitely.	2016-06-06 21:56:02 -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	f922d38ed2	The Vic now captures the ROMs sent to it and has just enough infrastructure to get to a black screen. Progress!	2016-06-05 10:51:07 -04:00
Thomas Harte	12243c40ad	Kicking the ball a little further down the road, ROMs and PRGs now reach the actual emulated machine.	2016-06-05 09:06:59 -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	4c33517228	Added ROMs to the project and ensured they don't get uploaded.	2016-06-04 22:03:38 -04:00
Thomas Harte	b10a06e700	A CRT is still absent but this moves the ball back into the C++ side's court.	2016-06-04 22:00:50 -04:00
Thomas Harte	06e1db8c85	This now gets as far as missing selectors.	2016-06-04 21:49:03 -04:00
Thomas Harte	eff28e95a4	Added XIB file.	2016-06-04 21:45:39 -04:00
Thomas Harte	404873fe58	Started sketching out infrastructure for Vic-20 support.	2016-06-04 21:43:50 -04:00
Thomas Harte	d6e8cd676a	Trimmed and reordered just a little.	2016-06-04 16:02:16 -04:00
Thomas Harte	68a8851c52	Increased parallelism, allowing a simplification in the GL view.	2016-06-02 22:29:09 -04:00
Thomas Harte	e3b95b8d2b	Back to asynchronous updates and drawing, to try to improve guarantees on audio latency; experimenting with whether other parts of the approach are fundamentally flawed; added a broad-phase for scheduled updates on the 2600.	2016-06-02 21:22:55 -04:00
Thomas Harte	11073daee1	Issues appear to be around timing generally. Working on it.	2016-06-02 20:15:48 -04:00
Thomas Harte	253e5a4203	With no regard to performance whatsoever, endeavoured to bring sound to the 2600. It's very scratchy, so something is wrong.	2016-06-02 19:50:16 -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	8dc66167be	Made an attempt to consolidate the Objective-C++ side of things based on the incoming CRTMachine::Machine.	2016-05-31 22:16:20 -04:00
Thomas Harte	5c4f35e13f	Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be.	2016-05-31 21:23:44 -04:00
Thomas Harte	40600b4bcb	Made sprite placement consistent at least. Not necessarily yet correct.	2016-05-18 22:07:24 -04:00
Thomas Harte	3765c5fbb5	Fixed error that would prevent an interrupting frame from ever being drawn.	2016-05-18 21:45:35 -04:00
Thomas Harte	ddfc9910e5	Sought to draw in a standard serial arrangement as and when bandwidth allows it.	2016-05-09 07:17:12 -04:00
Thomas Harte	1bb92550f8	It's 2016.	2016-05-02 22:02:06 -04:00
Thomas Harte	6982e945fb	Fixed those issues breaking GL state, I hope.	2016-05-01 16:17:52 -04:00
Thomas Harte	8538b62ea2	Made an attempt to extract and consolidate the logic behind the intermediate shaders.	2016-04-28 21:04:59 -04:00
Thomas Harte	496d979aca	Made a decision to clean up by creating per-shader classes. Well, more or less. First thing to be factored out: the output shader.	2016-04-27 22:29:54 -04:00
Thomas Harte	416c944f02	Experimental: let's try accumulating history directly in the framebuffer.	2016-04-26 21:41:39 -04:00
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	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
