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
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
