Thomas Harte	b5406b90cd	Introduces a new class hierarchy for disk images. ... Increasing independence of format-specific stuff and generic caching without mangling them into a common namespace, and allowing in some cases for a decrease in read/write blocking.	2017-09-22 20:28:11 -04:00
Thomas Harte	6633537fb8	Discovering that there is such a thing as P81 — a ZX81 file without the name omitted — added support for it. Extended FileHolder while I was here to retain the file name and be able to supply its extension, as my quick-fix test-the-last-character approach to o/p/80/81 discrimination stops working with p81 thrown into the mix and this feels like the correct factoring.	2017-07-22 16:02:25 -04:00
Thomas Harte	fa617eac6b	Spotted that pilot and data segments have different encodings — of course! — and attempted to adapt.	2017-07-17 07:34:10 -04:00
Thomas Harte	3b29e6a473	Ensured SSD and ADFs are grown if required.	2016-12-30 18:08:12 -05:00
Thomas Harte	bfe6c0a0c1	Ensured that FileHolder gets a writeable file reference if one is possible, and records whether the file in hand is read-only. So now the SSD class can answer honestly.	2016-12-28 20:09:14 -05:00
Thomas Harte	8499783b14	Dragged multibyte primitives and signature checks up to the base class. Implemented support for Oric MFM-style .DSK, at the file format level.	2016-11-21 20:47:16 +08:00
Thomas Harte	31c2548804	Created a base class for the boilerplate fopen stuff, switched as many classes as possible to its use, switched to postfix underscores and non-camelCase names.	2016-11-21 20:14:09 +08:00
