Thomas Harte	8545707b54	Reinstituted the playfield. Probably needs more buffering though. Time to look into delays.	2017-01-30 21:38:58 -05:00

Thomas Harte	92754ace7a	Some mild fixes get me up to having a rolling screen of vertical lines. Which is what I was hoping for right now!	2017-01-29 22:16:23 -05:00
Thomas Harte	1cc13b2799	Merge branch 'master' into TIAImprovements	2017-01-29 16:13:46 -05:00
Thomas Harte	38f944bc34	This needs to be a memmove as the areas may overlap.	2017-01-29 16:13:33 -05:00
Thomas Harte	427175b9c0	Added an extra flag to avoid potential race condition on is_full_, being reset from the background despite a write area not having been allocated.	2017-01-29 16:13:28 -05:00

Thomas Harte	9c3597c7e3	Attempted to reintroduce enough logic to handle [most of] line timing, such that WSYNC works. Initial objective is to get back to having a working background.	2017-01-29 13:47:36 -05:00

Thomas Harte	a246530953	Supposing the TIA were implemented, this is (more or less) what the Atari 2600 would now look like.	2017-01-28 21:46:40 -05:00
Thomas Harte	0ffded72a6	Created a placeholder class for a factored-out TIA. There's a bit more it'll need to do, like vending (or receiving) a CRT but this is the full hardware stuff, I think.	2017-01-28 16:19:08 -05:00

Thomas Harte	99fcbb55d1	Attempted to improve layout.	2017-01-12 22:11:25 -05:00
Thomas Harte	6f78ecd12b	Added a small pictorial example. Hardly the best, but a step in the right direction.	2017-01-12 22:06:45 -05:00
Thomas Harte	ced644b103	It seems likely that an AY divides its clock by 8, not 16. I had conflated wave frequency and counter clock.	2017-01-11 22:03:01 -05:00
Thomas Harte	be1cb2a551	Fixed NTSC phase.	2017-01-11 21:31:24 -05:00
Thomas Harte	b4159295f6	Switched to using quads for intermediate draws. The specific concern is the flexibility offered in the GL spec as to line drawing algorithms. And even if a driver implements exactly to spec then it should omit the final pixel.	2017-01-11 21:18:41 -05:00
Thomas Harte	d0a93409e6	Made an attempt to simplify in-shader phase calculation, now that output position is a direct multiple of phase.	2017-01-11 08:18:00 -05:00
Thomas Harte	4c3669f210	Reduced precision of input phase, but I'm not necessarily persuaded by it as a move. However it's clear that something is off in that whole area. But if phase is locked by output position, do I need to retain this level of complexity? Also ensured that intermediate buffers prior to the final are sampled using the nearest sampling mode, also to reduce precision errors.	2017-01-10 22:08:07 -05:00
Thomas Harte	eeb646868b	Switched off filtering, at least temporarily, to try to ensure that sampling is all where it should be.	2017-01-08 19:53:08 -05:00
Thomas Harte	3d789732a2	Switched back to full buffer clearing. Until I can figure out the source of noise.	2017-01-08 19:50:31 -05:00
Thomas Harte	d2a7d39749	Ensured the output lock isn't held while talking to the delegate.	2017-01-08 19:49:21 -05:00
Thomas Harte	9521718120	Colour phase is multiplied by 255, not 256.	2017-01-08 17:21:26 -05:00
