89ace671a4 Corrected unload time. Was 8000 times too short. 2017-08-12 09:44:01 -04:00
Thomas Harte
e7db2a2f6d Sought to introduce head loading and unloading delays. 2017-08-12 09:36:21 -04:00

8c33ac71ee Merge pull request #191 from TomHarte/Precache

2d81acb82e Upped C++ standard to C++14 and added an #if that's intended to use the built-in std::gcd when compiled on C++17 or better. Fixed for new signedness warnings resulting for taking the step to C++14. 2017-08-11 19:18:45 -04:00
Thomas Harte
82ca49c840 Adjusted to avoid calls to ::greatest_common_divisor(numerator % denominator, denominator) unless necessary. 2017-08-11 19:05:46 -04:00
Thomas Harte
bfe297052d Picked up another subtlety: disk names may be outside of the ones a user could type, in which case they definitely don't affect the decision. 2017-08-11 18:59:38 -04:00
Thomas Harte
ffb1a14ace Minor: clear status registers before a read data. 2017-08-11 18:56:33 -04:00
Thomas Harte
7e35e44934 Added an extra sanity check on treating system disks as system disks. 2017-08-11 18:46:39 -04:00

0c8769e335 Just to be safe. 2017-08-11 18:41:08 -04:00

83c7d34df2 Switched to populating the sector cache with everything in a track the first time anything on that track is requested. That avoids the problem whereby each request of a non-existent sector costs two spins. 2017-08-11 18:40:16 -04:00

ad3c9842d7 Merge pull request #190 from TomHarte/SingleImplicit
Corrects a couple of CPC static analysis pitfalls
2017-08-11 16:41:03 -04:00

44dace2eef Made an attempt not to interrogate files that definitely don't have the normal header. 2017-08-11 16:34:29 -04:00

a12671010a Sector size is now reported, and CRC failures are merely indicated, not cause for a sector to be thrown away. 2017-08-11 16:23:33 -04:00
Thomas Harte
23c149368b Broadened CPC data disk analysis to spot when there is only one implicitly-runnable file, rather than only one without suffix. 2017-08-11 16:23:00 -04:00

09716d4716 Merge pull request #189 from TomHarte/CPCSystemDisks
Corrects analysis of CPC system disks
2017-08-11 15:56:35 -04:00
Thomas Harte
4b7c504d22 Corrects analysis of system disks — they have a catalogue that is correct read, but can be launched without reference to it. 2017-08-11 15:55:33 -04:00

1e4f9d4eda Merge pull request #188 from TomHarte/AYFidelity
Switches to guessing that the AY doesn't reset its dividers upon frequency changes
2017-08-11 14:50:11 -04:00

0f75525640 Merge pull request #187 from TomHarte/CRCErrors
Extends the built-in [M]FM encoder to be able to produce incorrect CRC values, and adjusts the CPC .DSK handler to request them when appropriate
2017-08-11 14:34:31 -04:00
Thomas Harte
edb088526f Simplified slightly, and updated TODO as to still-missing functionality. 2017-08-11 14:33:34 -04:00

80ebc63101 Updated the SSD file format container to specify sector sizes, now that it's no longer implicit. 2017-08-11 14:30:35 -04:00
Thomas Harte
cf1403bc79 Increased documentation. 2017-08-11 14:27:07 -04:00
Thomas Harte
fcf63a7547 Expands the [M]FM encoder to respect some new Sector flags: it will now wilfully make CRC errors, omit data, include data that is different than the ID's declared length, write deleted data, and can be commanded as to header/data gaps and what should be within them. All based around expanding towards the needs for reproduction of the CPC's .DSK file format. 2017-08-11 14:24:50 -04:00

9c0b75faba Merge pull request #186 from TomHarte/CPCTyper
Introduces typer support for the Amstrad CPC.
2017-08-11 12:35:43 -04:00

1f2bfc9581 Ensured tape loading really begins. 2017-08-11 12:30:36 -04:00
Thomas Harte
14ab03d1e0 Added a further fallback: if all files have an extension but one doesn't, take that one. 2017-08-11 12:27:50 -04:00
Thomas Harte
3831fbaca2 Ensured the ZX80 and '81 also provide the necessary hook for destruction. 2017-08-11 12:11:01 -04:00
Thomas Harte
1d8edf58dd Ensured that a virtual destructor is declared, so that the various automatically-generated real constructors get in on the action. 2017-08-11 12:07:48 -04:00
Thomas Harte
4785e316ff Now with exposition. 2017-08-11 11:36:03 -04:00

44da9de5b0 Tweaked typing timing expectations. 2017-08-11 11:35:28 -04:00
Thomas Harte
4ecd093891 Fixed test for termination of a key sequence; the previous error will have seen this reduce all multi-key sequences to just the one, and expand single-key sequences to "probably" two, posting an out-of-bounds code to the machine at completion. 2017-08-11 11:35:14 -04:00
Thomas Harte
dd4bc87d52 Fixed: should be a full-path #ifdef guard, given that this is one of the classes named relative to its namespace. 2017-08-11 11:21:33 -04:00
Thomas Harte
570d25214e Made an initial attempt at typer support for the CPC. 2017-08-11 11:21:07 -04:00

f0b7e58968 Merge pull request #185 from TomHarte/CPMCatalogue
Introduces a CP/M catalogue parser, as a basic for the CPC's static analyser
2017-08-11 11:00:49 -04:00
Thomas Harte
0411b51582 Added an attempt to deal with 16-bit allocation units, and to ensure middle-of-file holes are respected. 2017-08-11 10:59:37 -04:00
Thomas Harte
dea782cff9 Added a "yeah, I don't know" fallback. 2017-08-11 10:47:45 -04:00
Thomas Harte
388dd99762 Advanced this just enough to suggest a loading command for most things. 2017-08-11 10:47:12 -04:00
Thomas Harte
026101a268 Killed logic_extents_per_physical, since I don't know how to handle it, and instituted tracks, to allow a decision about short versus long allocation units. 2017-08-11 10:46:50 -04:00
Thomas Harte
734099a956 Threw a sector cache into my MFM parser, in an attempt to cut down analysis costs. Also made it aware of multiple heads. 2017-08-11 10:29:13 -04:00
Thomas Harte
6be5851484 Cleaned up. 2017-08-10 22:34:29 -04:00

994179f188 Taking a whole bunch of guesses, this might be correct. 2017-08-10 22:33:08 -04:00
Thomas Harte
6a65c7a52a Started working on a CPC-oriented analyser; for now I just want to be able to make a good guess at the appropriate file to load from a disk. As it turns out, the CPC simply adopts the CP/M format, so a generic parser is appropriate. This is its beginning. 2017-08-10 17:10:21 -04:00

Reduces CRTC counter sizes to match real hardware; introduces a CRT gamma transform
2017-08-10 16:00:39 -04:00
Thomas Harte
62eadbb51a Adjusted gamma ratio to be the correct way around. The PAL midrange should be slightly darker now. 2017-08-10 15:36:27 -04:00
Thomas Harte
ad8c8166bc Built in gamma conversion for all machines, assuming an output of 2.8 for PAL, 2.2 for NTSC. 2017-08-10 15:17:08 -04:00
Thomas Harte
a5593bec79 Threw in support for the light-pen trigger. 2017-08-10 15:00:14 -04:00
