More or less rewrote, to use a filled-per-chunk buffer of upcoming pulses rather than working them out as requests come. Which is more straightforward — all the code for a particular chunk goes in exactly one place — and much easier to extend. So threw in a provisional 0104 implementation.

If loading automatically, assume that whatever was in the machine target set up the machine and don't override it. Too dodgy? More thought required.

Added logic to try to spot when the first program is BASIC and, if so, what the correct memory model is, then to get that information to the Vic. Though it currently then gets overwritten by the view controller. Grrrr.

CRCs are just stored reversed. Of course. So this should be sufficient to load each chunk of an Acorn file.

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.

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.

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?
