87a021ec2d Made further attempt to get as fas as having the Z80 attempt to do something. 2017-05-16 22:19:40 -04:00
Thomas Harte
189317b80c Added enough of a Z80 test machine to bridge up into Swift. 2017-05-16 22:05:42 -04:00
Thomas Harte
4f0775cc7c Imported the Zexall.com tester, as a first thing to throw at the Z80 to be. 2017-05-16 21:37:09 -04:00
Thomas Harte
7190f927b7 Factored out the stuff that both all-RAM processors would share, rather than duplicating it. 2017-05-16 21:28:17 -04:00
Thomas Harte
d559d8b901 Continued edging towards getting the absolute basics of a testable Z80, for test-driven development. Corrected old-fashioned instance naming issues with the corresponding 6502 class and removed an unnecessary source file while at it. 2017-05-16 21:19:17 -04:00

Corrects infinite loop when performing GCR analysis
 2017-05-16 20:54:24 -04:00
Thomas Harte
df4d4467b3 Ensured GCR parser spins the disk. 2017-05-16 20:53:06 -04:00

Formalises reasoning for the colour phase clamp and offset...
 2017-05-16 20:47:20 -04:00
Thomas Harte
2ee8a7056e Corrected TIA no longer to assume phase is an automatic quarter askew. 2017-05-16 20:43:28 -04:00
Thomas Harte
a5075d9eb5 Formalised the reasoning behind the colour phase fix-up and made it an opt-in per-caller value. Only the Oric currently needs to opt in. 2017-05-16 20:31:39 -04:00
Thomas Harte
50bb4f0142 There's finally a loop in here, at least. 2017-05-15 22:25:52 -04:00
Thomas Harte
df80c37adb Renamed TestMachine to TestMachine6502 since there's going to be multiple of them. 2017-05-15 08:18:57 -04:00
Thomas Harte
7da51602d5 Moved flush, added run_for_cycles, which does nothing right now. 2017-05-15 07:59:21 -04:00
Thomas Harte
5152517887 Added the boilerplate stuff necessary to query registers. 2017-05-15 07:55:53 -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
f2a1a906ff Adapted what negligible amount there is of the z80 as per the new CPU namespace. 2017-05-14 22:15:16 -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
b81a2cc273 First tentative steps towards adding a Z80 implementation. 2017-05-14 17:46:41 -04:00

Formally withdraws the 'load automatically' option for the Vic
 2017-05-14 17:03:33 -04:00
Thomas Harte
8e35e913bb Formally withdrew the 'load automatically' option for the Vic, having removed that option elsewhere. 2017-05-14 16:59:24 -04:00

81c5f4ab19 Merge pull request #122 from TomHarte/16bit6560 
Increases VIC-I intermediate format to 16 bit and corrects output colours
 2017-05-13 22:03:08 -04:00
Thomas Harte
e270b726b3 Tweaked blue, increased saturation. 2017-05-13 22:01:02 -04:00
Thomas Harte
c2b5a9bb1f Minor fix: given that phase is now a function of position, stop nudging position. 2017-05-13 21:50:48 -04:00
Thomas Harte
44ce7fa54c Corrected luminances across the board, and PAL colours. 2017-05-13 21:50:09 -04:00
Thomas Harte
b0142cf050 Made an updated stab at NTSC colours. 2017-05-13 14:29:36 -04:00
Thomas Harte
a340331229 Introduced 1-bit of saturation, returning black and white as black and white. 2017-05-11 21:31:58 -04:00
Thomas Harte
b14c892740 Switched to a safer RAII approach to this lock. 2017-05-10 21:29:39 -04:00
Thomas Harte
15d17c12d5 Switched the 6560 to two bytes per pixel, since one isn't sufficient for precision and because mixing up the implementation might help me to figure out what's amiss. 2017-05-09 21:22:01 -04:00

Permits ROM-area located PRGs that are not a power-of-two in size
 2017-05-08 22:18:47 -04:00
Thomas Harte
5d91a2600d Permitted ROM-style PRGs that are not a power-of-two in size, and added extra safety checks on loading data from a tape. 2017-05-08 22:15:35 -04:00
Thomas Harte
cb66c7e2dc Performed some minor tidying. 2017-05-08 21:05:35 -04:00

58488c93be Merge pull request #120 from TomHarte/Vic20Colours 
Corrects — and improves — Vic-20 tape loading
 2017-05-08 20:59:29 -04:00
Thomas Harte
61f8f2f18c Switched to a more straightforward way of exiting from tape data loading. 2017-05-08 20:58:55 -04:00
Thomas Harte
7b43ae0a92 Implemented a catch for loading the data portion of files. 2017-05-07 22:22:59 -04:00
Thomas Harte
2807e3134f Implemented speedy header finding. So that's half of it. 2017-05-07 20:32:48 -04:00
Thomas Harte
0771363f3b Removed one piece of unnecessary logging. 2017-05-06 22:22:03 -04:00
Thomas Harte
1f56e85f6d Centralised resetting of tape files within the static analyser, having implemented it patchily. 2017-05-06 22:19:08 -04:00
Thomas Harte
2edf73908c Temporarily disabled the existing fast loading implementation in pursuit of another, and started trying to correct the lack of connection between the userport VIA and the tape drive. 2017-05-06 22:00:12 -04:00
Thomas Harte
6a37a02eee Switched to std::ostringstream to avoid the need to make a string length count (and I was one off when loading a disk). 2017-05-06 19:55:42 -04:00
Thomas Harte
5998123868 Added some consts, for a minor safety improvement. 2017-05-06 19:53:24 -04:00

26cb903b08 Merge pull request #119 from TomHarte/C11 
Ejects the deprecated OSAtomicTestAnd[Re]Set test-and-[re]set in favour of C11's atomic_flag.
 2017-04-15 21:45:48 -04:00
Thomas Harte
92a8b68859 Dumped Mach-specific test-and-set in favour of ordinary C11. 2017-04-15 21:41:59 -04:00

4127350abe Merge pull request #118 from TomHarte/HighResolutionAtariAudio 
Introduces a higher source sampling rate for Atari audio
 2017-04-15 21:21:58 -04:00
Thomas Harte
ed6b135015 Made final switch to permit high-sampling rate Atari audio. 2017-04-15 21:18:00 -04:00
Thomas Harte
f95015c7f6 Pulled out the divisor for audio. 2017-04-03 21:16:39 -04:00
Thomas Harte
defec2c9b0 Fixed: operation reads now fulfil the promise of seeding the value to be read with 0xff. 2017-03-26 20:56:27 -04:00

04921e64de Merge pull request #117 from TomHarte/AudioRace 
Works around what appears to be a bug in Apple's AudioQueue.
 2017-03-26 20:29:41 -04:00
Thomas Harte
bdd432fe1d Added an ugly workaround for the empirical sound shutdown issues. 2017-03-26 20:28:04 -04:00
Thomas Harte
6e9ab9f330 Merge pull request #116 from TomHarte/YarsBug 
Fixes a bug in which TIA access during the border would flush all motion steps.
