Thomas Harte	6be46ae921	Mostly restores Atari 2600 output. PAL colours need work.	2018-11-29 18:26:05 -08:00
Thomas Harte	be01203cc1	Starts to expand the range of supported 6502s. ... This fully implements the NES 6502 because, well, it's virtually no extra work, and ensures that RDY takes effect on write cycles on 65C02s.	2018-08-13 22:17:22 -04:00
Thomas Harte	76a73c835c	Forces 6502 consumers to declare which model — the original, 65C02 or 65SC02. ... All present machines use a regular 6502.	2018-08-06 20:06:07 -04:00
Thomas Harte	5d6b5d9f10	Eliminates all emdashes in cross-platform code.	2018-05-13 15:34:31 -04:00
Thomas Harte	0b771ce61a	Removes all instances of the copyright symbol.	2018-05-13 15:19:52 -04:00
Thomas Harte	1100dc6993	Opens up .bin and .rom to all cartridge platforms, and adds a confidence estimate to the Atari 2600.	2018-03-07 14:26:07 -05:00
Thomas Harte	ac80d10cd8	Separates the component parts of running an audio stream: task deferral, filtering and generation. ... Walking towards improving opportunities for composition.	2017-12-17 21:26:06 -05:00
Thomas Harte	2e15fab651	Doubles down on <cX> over <X.h> for C includes, and usage of the namespace for those types and functions.	2017-11-11 15:28:40 -05:00
Thomas Harte	ee71be0e7e	Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.	2017-08-21 21:56:42 -04:00
Thomas Harte	360c8a99a3	Adjusted Atari2600 actually to use the nominated type of bus extender.	2017-08-16 12:57:32 -04:00
Thomas Harte	06e31f5102	Consequential to the 6502 change, severs the Atari 2600's cartridge container from its former attempt at runtime polymorphism, in favour of each cartridge's specific hardware being defined as a 'bus extender'.	2017-08-16 12:39:15 -04:00
Thomas Harte	42b5b66305	Remove the 6502's use of runtime polymorphism in favour of ordinary templating.	2017-08-16 11:56:52 -04:00
Thomas Harte	4abd62e62b	Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.	2017-07-27 22:05:29 -04:00
Thomas Harte	279c369a1f	Switched to Cycles as the result from the 6502 perform_bus_operation, helping slightly to clarify what you're intended to return and reducing type jumping within the 6502 implementation.	2017-07-25 22:21:09 -04:00
Thomas Harte	d9c6b3bcf7	Corrected TIA's WSYNC lookahead to accept Cycles.	2017-07-25 22:13:41 -04:00
Thomas Harte	40339a12e1	Formalised the use of a cycles count with a divider, bringing a few additional plain-int users into the fold.	2017-07-25 07:15:31 -04:00
Thomas Harte	90bf6565d0	Reduced int/Cycle conversions in the Electron and on the Atari 2600, where the current framework makes it possible to do so.	2017-07-24 22:53:13 -04:00
Thomas Harte	2ff157cf7a	Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that.	2017-07-22 22:17:29 -04:00
Thomas Harte	83628b285b	Experimentally turned the 6502 into a clock receiver. No problem encountered.	2017-07-22 21:52:21 -04:00
Thomas Harte	eb8a2de5d6	Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80.	2017-05-15 07:38:59 -04:00
Thomas Harte	0808e9b6fb	Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair.	2017-05-14 22:08:15 -04:00
Thomas Harte	a26b87f348	Fixed: mistake was failure to count ready cycles.	2017-03-20 20:44:03 -04:00
Thomas Harte	c3d82f88a5	Tidied up and commented on the Activision stack implementation.	2017-03-18 21:01:58 -04:00
