Thomas Harte	aca1fa0577	Returned some video output. Enough significantly to reduce my paranoia.	2016-11-17 13:37:53 +08:00
Thomas Harte	1f91d29434	Progressed to usage of an array builder and a texture builder up to the point of a successful build.	2016-11-17 12:26:04 +08:00
Thomas Harte	0f3b02edb7	Switched to postfix underscores and gave this class ownership of a texture builder and an array builder, though it presently uses neither.	2016-11-17 11:00:11 +08:00
Thomas Harte	57f0648742	Fleshed out first implementation of ArrayBuilder, albeit that I need to implement exhaustion properly, as soon as I think of a sensible way to handle synchronisation.	2016-11-17 10:39:30 +08:00
Thomas Harte	324a1de43d	Started pulling out array construction as a separate task.	2016-11-17 09:20:49 +08:00
Thomas Harte	c04a116a05	Fixed comment.	2016-11-16 23:14:56 +08:00
Thomas Harte	edeafd4d94	Wait, OpenGL textures go the other way.	2016-11-16 23:14:15 +08:00
Thomas Harte	6ac20e0066	Pushed responsibility for submitting texture contents up to the texture builder, simplifying the interface.	2016-11-16 23:13:06 +08:00
Thomas Harte	5c5e44874f	Even better: why include the 'Input' prefix when there's only one?	2016-11-16 22:57:17 +08:00
Thomas Harte	04b2688683	Attempted to reduce allocations.	2016-11-16 13:25:50 +08:00
Thomas Harte	c1a509910d	Documented this interface, albeit that the English could do with a second pass, and very sightly simplified inline with current usage.	2016-11-16 13:15:50 +08:00
Thomas Harte	4d0d5eb919	Renamed the 'input buffer builder' to the 'input texture builder' to be explicit about what sort of buffer, and killed the prefix since it's namespaced. Also switched to std::vector.	2016-11-16 12:31:32 +08:00
Thomas Harte	4ee4400801	Removed dead code.	2016-11-16 11:57:22 +08:00
Thomas Harte	6cb4950db4	Improved run-off area.	2016-11-16 11:53:15 +08:00
Thomas Harte	9ee11d7765	At the expense of API simplicity, at least for now, resolved the most glaring cause of dirty lines.	2016-11-16 11:34:05 +08:00
Thomas Harte	44d3fd6d5b	Fixed mistimed reset of the target output line. Now all that's left is occasional noise.	2016-11-16 11:22:12 +08:00
Thomas Harte	7a737e0790	Both pathways start with a buffer that clears to black. So no need to keep going on about it.	2016-11-16 11:12:08 +08:00
Thomas Harte	f63e849092	Sought completely to eliminate the outgoing concept of 'clearing zones'.	2016-11-16 11:10:34 +08:00
Thomas Harte	311f8c0b47	Restored audio.	2016-11-16 11:10:07 +08:00
Thomas Harte	294adde344	Eliminated zoned clearing, in favour of a complete buffer clear on each load and attempted to reduce locking. But imperfectly.	2016-11-16 10:59:12 +08:00
Thomas Harte	ccedb6bea6	Introduced an intermediate buffer that collects lines before flushing them to the output buffer.	2016-11-16 10:49:18 +08:00
Thomas Harte	ba2adf8bb1	Normalised on std::vector rather than std::unique_ptr<uint8_t *> as (probably?) more idiomatic. Improved structure slightly. Introduced a container for line data, albeit one that isn't yet used.	2016-11-16 10:34:54 +08:00
Thomas Harte	f84a28b566	Merge pull request #76 from TomHarte/Disassembler ... Introduces a first attempt at 6502 disassembly	2016-11-15 19:52:12 -05:00
Thomas Harte	97811fe590	Made minor fix to ensure that a header that appears to extend beyond the end of an Oric .TAP doesn't create an ostensibly endless tape.	2016-11-15 12:02:03 +08:00
Thomas Harte	8b40ae03ca	Extended analysis to spot IRQ and NMI vector changes, for titles that simply adjust those then exit. Ensured Oric emulator can type and load quickly on an Oric 1 just as well as on an Atmos.	2016-11-15 11:05:53 +08:00
Thomas Harte	e2cdfae8a7	The emulated Oric now has access to both versions of the BASIC ROM and picks between them based on the static analyser's recommendation.	2016-11-15 10:39:16 +08:00
Thomas Harte	ab64731d51	Fixed off-by-one recording of disasssmbled addresses; added logic to the Oric static analyser to try to guess between BASIC 1.1 (the preferred option in a tie-break or if no information is found) and BASIC 1.0.	2016-11-15 10:31:47 +08:00
Thomas Harte	1bffc70494	In theory that's a full disassembler, at least as far as I want to go for now. Time to test.	2016-11-15 08:19:57 +08:00
Thomas Harte	a5fc45e66e	Started fleshing this out; addressing modes are completely decoded, along with a bunch of opcodes, but appropriate address advancement isn't in yet, and neither is filling in derived metadata.	2016-11-14 12:19:09 +08:00
Thomas Harte	f08e87c6c1	Merge branch 'master' into Disassembler	2016-11-11 20:32:18 -05:00
Thomas Harte	7eeaac23e7	Reversed myself. I once again do not think the clock is divided by 256 for envelopes.	2016-11-11 20:31:48 -05:00
Thomas Harte	1b66847647	Started trying to implement something sufficient of a 6502 disassembler.	2016-11-11 20:10:58 -05:00
Thomas Harte	4ba39d13b5	Merge pull request #75 from TomHarte/AudioUpdates ... Reintroduced a separate thread for audio processing and made various AY fixes	2016-11-10 20:32:57 -05:00
Thomas Harte	77987bf31e	Decided to go with divide by 256 for the envelope counter after all.	2016-11-09 21:51:56 -05:00
Thomas Harte	77ce200fbb	Simplified/corrected AY tone/noise mixer logic, and made a new guess at the effect of reading registers that are smaller than 8 bits.	2016-11-09 21:21:17 -05:00
Thomas Harte	9c550c594a	Moved audio work back into its own thread, but this time it queues up an all happens only upon a flush. Hopefully to resolve synchronisation cost concerns.	2016-11-09 21:17:50 -05:00
Thomas Harte	f3c8c57043	Merge pull request #74 from TomHarte/WaveLengthOric ... Switches to Oric tape parsing by full-cycle length only	2016-11-09 06:41:56 -05:00
Thomas Harte	fce48b9b8c	I am instructed that the Oric actually catches only positive transitions, and compares the distance between those to a threshold. So here's an altered version of the tape parser that does that.	2016-11-09 06:37:10 -05:00
Thomas Harte	79dd062941	Merge pull request #73 from TomHarte/TapeClasses ... Clarifies that a tape parser does not own a tape, it is merely lent one	2016-11-07 22:04:37 -05:00
Thomas Harte	64827931bf	Switched the Oric implementation simply to rely upon the Storage-level tape parser. So now there's only one, authoritative one of those.	2016-11-07 21:57:58 -05:00
Thomas Harte	c257e7f58d	Implemented better sync-to-zero and discovered a header counting bug plus, probably, a misleading representation of gaps in the Oric TAP decoder.	2016-11-07 20:17:06 -05:00
Thomas Harte	80702616ea	Had a quick go at using the Oric parser for static analysis. Found out that synchronisation is lost. Need to investigate.	2016-11-06 22:56:38 -05:00
Thomas Harte	7205c3f82b	Made an attempt to build in Oric slow/fast detection.	2016-11-06 21:31:10 -05:00
Thomas Harte	d1ef2f7c63	Made an attempt to consolidate what I learnt of Oric encoding while building this hastily and untidily directly into the Oric implementation. ... (while adding support for the slow tape encoding mode)	2016-11-06 19:22:09 -05:00
Thomas Harte	353c1c8ea3	Shifted ownership of PETSCII -> string conversion down to the storage layer, where it's useful for tape parsing.	2016-11-06 18:43:51 -05:00
Thomas Harte	1b15bc3a6c	Started relocating the tape parsers down from static analyser to storage, to signify that they may be used by the emulation (if fast loading is supported on that machine).	2016-11-06 16:13:13 -05:00
Thomas Harte	093eb55fc6	The parsers no longer own a tape, merely taking one as an argument. So they can be an adjunct.	2016-11-06 15:25:18 -05:00
Thomas Harte	bc83a8f2d0	Merge pull request #72 from TomHarte/RefactoredTyper ... Attempts to clean up the Typer code, reducing duplication and improving per-platform readability	2016-11-05 15:29:26 -04:00
Thomas Harte	45b169f341	Made a few mapping fixes, clarified where the default reset code lives, ensured the Oric and Vic clear their keys when the typer ends.	2016-11-05 15:28:03 -04:00
Thomas Harte	c21bef4283	Project cleaning.	2016-11-05 15:08:22 -04:00
