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
