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

360c8a99a3 Adjusted Atari2600 actually to use the nominated type of bus extender. 2017-08-16 12:57:32 -04:00

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

42b5b66305 Remove the 6502's use of runtime polymorphism in favour of ordinary templating. 2017-08-16 11:56:52 -04:00

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

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

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

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

83628b285b Experimentally turned the 6502 into a clock receiver. No problem encountered. 2017-07-22 21:52:21 -04:00

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

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

a26b87f348 Fixed: mistake was failure to count ready cycles. 2017-03-20 20:44:03 -04:00

4c3cc42c91 This gives a very noisy version of the real audio. 2017-03-20 20:38:29 -04:00
Thomas Harte
f3f4e1a541 Made a first, hacky, attempt at audio. 2017-03-20 19:35:51 -04:00

4722f6b5c4 Fixed sprite disappearance: test should be applied predecrement, not post — it relates to the address being used this access, not the next one. 2017-03-19 18:58:35 -04:00

7d8d1c7828 Fixed 'random' number generator. 2017-03-19 18:54:35 -04:00

4bb70e7d31 Resetting the mask upon low byte write appears to resolve some issues. 2017-03-19 18:49:37 -04:00

321030bb44 Added a slightly faulty but seemingly 'close' version of masking. 2017-03-19 18:28:06 -04:00

6c161b1150 This gives something that might be the correct background. 2017-03-19 17:49:48 -04:00

d5c37c8619 Shushed a little, so as to be able to see a reasonable amount of output during my lifetime. 2017-03-19 17:38:54 -04:00

7c66c36d3f Attempted at least to manage appropriate data storage. 2017-03-19 17:31:08 -04:00

031a68000a Added a class to contain the Pitfall 2 pager and a skeleton of initial work. 2017-03-18 22:08:47 -04:00

c3d82f88a5 Tidied up and commented on the Activision stack implementation. 2017-03-18 21:01:58 -04:00
