Thomas Harte	3c8bf52fb8	Believing my 64kb memory map not currently to work, temporarily disabled reference to it in the static analyser.	2017-07-21 20:43:56 -04:00
Thomas Harte	238348c885	Performed the initial wiring to announce that this application supports TZX files and to route them to the ZX80/81 static analyser. The TZX class itself does not yet do much beyond basic validation. I think it'll be easiest if it follows in UEF's footsteps in queuing up pulses ahead of time, so some factoring out is now required.	2017-07-16 21:33:11 -04:00
Thomas Harte	fc8313430a	Added an early exit if what was read as a header turns out pretty much certainly not to be a header.	2017-07-13 21:26:45 -04:00
Thomas Harte	33d16ae0cd	Fixes: individual static analysers reset tapes, for potential successors. The ZX81 file analyser no longer overruns its buffer upon receiving a file that is shorter than 11 bytes.	2017-07-12 21:34:08 -04:00
Thomas Harte	368bff1a82	Added a shell class that will one day be able to parse CSW files, plus the logic and metadata to instantiate it when a CSW presents itself.	2017-07-10 21:43:58 -04:00
Thomas Harte	ac59dd8b1d	Added enough typing to issue a load command. No thoughts as to running yet though.	2017-07-09 22:07:12 -04:00
Thomas Harte	77aa3c187e	Rebranded ZX80O as ZX80O81P, with an eye to making it accept ZX81 .p files. Adjusted the initial selection part of the static analyser appropriately.	2017-06-11 21:38:32 -04:00
Thomas Harte	8116f85479	Allowed the static analyser to specify a ZX80 or 81, and a memory model. Neither is respected yet in the machine.	2017-06-11 19:12:20 -04:00
Thomas Harte	7e10c7f9d8	Relocated the ZX80/81 concept of a 'file' out from Tape into Data, given that it's an exact duplicate of memory.	2017-06-08 19:09:51 -04:00
Thomas Harte	350b36df25	Wired in an attempted usage of the new tape parser.	2017-06-07 17:30:53 -04:00
Thomas Harte	d2637123c4	Added necessary support to get as far as an empty window when attempting to load a piece of ZX80 software.	2017-06-04 17:55:19 -04:00
Thomas Harte	02b7c3d1b0	Added the necessary wiring to get into a ZX80/81-oriented part of the static analyser, which could in principle post a ZX80 target.	2017-06-04 17:04:06 -04:00
Thomas Harte	655809517c	Ensured that there is a subclass of file that is entrusted to load .O/.80 files, and that the code routes such files to it, noting that it should consider whether a ZX80 is required.	2017-06-04 16:37:03 -04:00
Thomas Harte	df4d4467b3	Ensured GCR parser spins the disk.	2017-05-16 20:53:06 -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	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	e01f3f06c8	Completed curly bracket movement.	2017-03-26 14:34:47 -04:00
Thomas Harte	a6897ebde0	Added an attempt to distinguish the MegaBoy (now with proper capitalisation) and a test for it.	2017-03-13 20:43:12 -04:00
Thomas Harte	582da14a14	Added an enumerated type and detection of Pitfall 2.	2017-03-13 08:15:36 -04:00
Thomas Harte	a9964ee0c8	Simplified CommaVid test.	2017-03-12 22:14:39 -04:00
Thomas Harte	b671df9906	'Perfected' the Activision stack paging detector.	2017-03-12 22:11:58 -04:00
Thomas Harte	0bcf9c30de	Added an attempt, at least, at spotting the Activision titles. Which reduces back to only the one breakage, but this is getting a bit too much like spotting the hard-coded bytes.	2017-03-12 21:14:12 -04:00
Thomas Harte	8c5e39c0c5	Adjusted Super Chip test to look for two portions of 128 bytes. It now spots Dig Dug and doesn't acquire any further false positives amongst the tested set. So failure to spot the Activision stack-based paging mechanism is now the only remaining failure.	2017-03-12 20:39:45 -04:00
Thomas Harte	cae48aaa95	Added an MNetwork test. Reduces failures to two of the set that I have: Dig Dug, which uses a Super Chip but has inconsistent bytes in its image, and Decathlon, which uses the Activision stack paging mechanism for which I don't yet have detection code.	2017-03-12 18:54:49 -04:00
Thomas Harte	37f4f6ba14	Cut down to one disassembly, now I know a bit more about how the non-Atari schemes work.	2017-03-12 17:50:24 -04:00
Thomas Harte	62b3c9dda8	Corrected 8k Tigervision test, putting detection failures below 10 (i.e. at 9) for the first time.	2017-03-12 15:41:48 -04:00
Thomas Harte	af9b7fbc30	Switched to a voting method for classifying 8kb ROMs.	2017-03-12 15:36:01 -04:00
Thomas Harte	de347ad7c8	Improved CBS RAM Plus and Super Chip detection exclusion, reducing error count to 15.	2017-03-12 14:03:17 -04:00
Thomas Harte	a4bba8a92e	Made a couple of lookup table fixes and corrected RAM region detection windows; failures now down to 19.	2017-03-11 23:18:30 -05:00
Thomas Harte	c7e973aab4	Extended test set a little, corrected current failures.	2017-03-11 20:51:25 -05:00
Thomas Harte	1c9dffe41f	Added an earlier exit.	2017-03-11 19:38:05 -05:00
Thomas Harte	bce5abd33b	Made an attempt to spot Tigervision paging requests.	2017-03-11 13:12:23 -05:00
Thomas Harte	33bda2d40c	Switched to image inspection for RAM guesses rather than disassembly. Which fixes the other Parker Bros titles.	2017-03-11 13:04:23 -05:00
Thomas Harte	2b5e3a600e	Made a first attempt at implementing the Parker Bros pager within the emulation.	2017-03-11 12:43:12 -05:00
Thomas Harte	8dbf9fd302	Started adding an attempt to distinguish between Atari and Parker Bros paging schemes.	2017-03-11 11:41:18 -05:00
Thomas Harte	abd4d2c42a	Extended has-RAM test to check all banks.	2017-03-05 11:58:52 -05:00
Thomas Harte	2a81ae1dec	Now required: at least four stores for RAM to be detected.	2017-02-28 20:28:14 -05:00
Thomas Harte	8f8b103224	Slightly tidier. Also in the interim: confirmed no remaining false positives or negatives from the existing published set.	2017-02-27 08:42:43 -05:00
Thomas Harte	1af415a88e	Okay, this is a bit desperate, but worth investigation.	2017-02-27 08:39:53 -05:00
Thomas Harte	fe07cd0248	Made another attempt to distinguish.	2017-02-27 08:06:57 -05:00
Thomas Harte	a3d339092e	Corrected callers of the 6502 disassembler.	2017-02-27 07:56:59 -05:00
Thomas Harte	837216ee9a	Adjusted semantics to allow for more complicated mappings, e.g. whereby supplied data repeats itself within a range.	2017-02-27 07:49:33 -05:00
Thomas Harte	0273860018	Sought to weed out further false positives on CommaVid, partly by introducing a record of internal calls, to pair with the now confusingly named outward_calls.	2017-02-26 21:58:09 -05:00
Thomas Harte	82c089cde4	Factored out paging type detection and, from that, took out 2k cartridge detection. Added an attempt at a CommaVid detector, which does not currently work.	2017-02-26 21:24:54 -05:00
Thomas Harte	8b1ec827e0	Made an initial, very naive attempt to recognise two types of expanded cartridge: those with a superchip and those with a CBS RAM+, in both cases by looking for instructions that appear to write into cartridge space.	2017-02-26 17:11:57 -05:00
Thomas Harte	153525f23d	Extended quality of known address read/write/modify mapping, and started recording internal accesses in addition to external.	2017-02-26 17:10:33 -05:00
Thomas Harte	87afa9140e	Took some provision steps towards paging type autodetection and communication. But I think this is a distraction.	2017-02-20 17:44:36 -05:00
Thomas Harte	7ab6023a0c	Ensured no attempt to call strcmp on null if a file name without an extension got into here.	2017-02-11 13:36:36 -05:00
Thomas Harte	f3d9aec8fc	Fixed Electron's support for automatically booting floppy disks.	2017-01-08 14:47:41 -05:00
Thomas Harte	e5cc77f22d	Added an extra sanity check.	2016-12-30 17:29:51 -05:00
