Thomas Harte	8901e94f0f	Fixed: was counting between low->high transitions rather than vice versa by adding low time then checking.	2016-09-06 07:06:46 -04:00
Thomas Harte	149cbb327b	Made something of a first attempt at a parser. Which is failing terribly.	2016-09-06 06:59:51 -04:00
Thomas Harte	8b933182af	Added enough wiring (hopefully) that the Commodore tape's GetFiles should be called when appropriate.	2016-09-06 06:39:40 -04:00
Thomas Harte	cfe8251166	Further documented interface, fixed a potential parsing blockage.	2016-09-05 22:12:52 -04:00
Thomas Harte	963e307d0c	Increased documentation.	2016-09-05 22:06:39 -04:00
Thomas Harte	05c24222d8	Liberated the tape parser template.	2016-09-05 20:02:35 -04:00
Thomas Harte	463b74301d	Sought to reduce the amount of heap nonsense.	2016-09-05 19:59:58 -04:00
Thomas Harte	11850b872d	Sought to emulate 0111 as a longer 0110 to test a particular HQ UEF. Some progress. Not great.	2016-09-05 18:28:43 -04:00
Thomas Harte	6239297212	Fixed off-by-one error on filename lengths and order-of-operations mistake preventing data CRC from being checked.	2016-09-05 18:15:15 -04:00
Thomas Harte	e25fee2332	I'm going back to believing in this test.	2016-09-05 17:55:40 -04:00
Thomas Harte	68874b6080	Fixed accidental implicit assumption that Acorn files will be at least two blocks.	2016-09-05 17:53:57 -04:00
Thomas Harte	93f5b5303e	Factored out the stuff I expect to be common to this tape nonsense, started looking at the one currently-failing tape. More on the latter to do.	2016-09-05 17:17:52 -04:00
Thomas Harte	6f62803814	Resolved dropping of every other file.	2016-09-01 08:35:28 -04:00
Thomas Harte	21e5f407d8	I need to get a bit more definitive on naming but this gets all the way to setting a configuration upon an Electron.	2016-08-31 22:03:42 -04:00
Thomas Harte	9d7962d6c0	Closed the loop on Electron analysis for now. Including loading command detection.	2016-08-31 20:24:13 -04:00
Thomas Harte	d8c0da7ccb	I think this should lead to a full representation of files on an Acorn tape, but subject to is_at_end working.	2016-08-31 19:57:09 -04:00
Thomas Harte	7b5d5858ff	CRCs are just stored reversed. Of course. So this should be sufficient to load each chunk of an Acorn file.	2016-08-30 08:13:40 -04:00
Thomas Harte	b3521ed187	Started working towards capturing everything there is to know about a file. CRC calculation appears to be flawed somehow at the moment.	2016-08-30 07:38:08 -04:00
Thomas Harte	6218f05b8c	This loads the name. That'll do for now.	2016-08-29 22:05:06 -04:00
Thomas Harte	963a479908	Made a quick first attempt at getting a file name from Acorn tape, failing terribly but at least formalising tapes being able to signal their end.	2016-08-29 21:53:06 -04:00
Thomas Harte	0032ad2634	Edging ever onwards; killed forced attempt at uniformity in targets, sketched out the interface for a next-file-from call to Acorn tapes.	2016-08-29 21:10:38 -04:00
Thomas Harte	d1abfc040c	Addressed my dithering here: the file format containers themselves should do nothing but inspect the data to find out whether it is of the correct format. The machine steps are there for machine-specific validation. So it's probably easier to treat a binary ROM image just as a binary ROM image. Therefore, the Acorn-specific .rom detection is now in an Acorn-specific area.	2016-08-29 08:48:49 -04:00
Thomas Harte	d9f0065154	Sketched out just enough classes to get through the get-contents-into-memory step of static analysis.	2016-08-28 12:20:40 -04:00
Thomas Harte	24938326ac	ROMs definitely have no behaviour other than responding to memory accesses. Cartridges might. So picked the more general term. Sketched out a class at least to parse PRG as though it were a cartridge. Hence the static analyser can guess at whether a PRG is a cartridge or an ordinary program.	2016-08-27 18:26:51 -04:00
Thomas Harte	a1b3a18d11	Started forcing a resolution on ROMs by doing. But have immediately misstepped. Rename coming momentarily...	2016-08-27 18:17:40 -04:00
Thomas Harte	56c0d70c1f	Gave disks their own namespace.	2016-08-27 17:15:09 -04:00
Thomas Harte	c0402d0c2b	Gave tapes their own namespace.	2016-08-27 17:09:45 -04:00
Thomas Harte	8c333059a8	Turning this into a slog: gave UEF a more appropriate name, got as far as now having to decide what to do about ROMs as to structure. I guess they're machine specific, so specific classes?	2016-08-27 16:40:21 -04:00
Thomas Harte	55ada536ac	Added a test call, further mutated result structure.	2016-08-27 14:25:16 -04:00
Thomas Harte	e68ff64045	Actually, this is less prescriptive.	2016-08-27 13:42:51 -04:00
Thomas Harte	5ffd9e4f0d	This is probably how the static analyser interface will look?	2016-08-23 21:35:59 -04:00
