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.

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.

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.

Adjusted semantics to allow for more complicated mappings, e.g. whereby supplied data repeats itself within a range.

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.

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.

|
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.

Took some provision steps towards paging type autodetection and communication. But I think this is a distraction.

Any Oric-format disks that are inserted now make it all the way to the Oric, along with a request to emulate the Microdisc. It has received a copy of the ROM. The ball is entirely in its court now.

Extended analysis to spot IRQ and NMI vector changes, for titles that simply adjust those then exit. Ensured Oric emulator can type and load quickly on an Oric 1 just as well as on an Atmos.

The emulated Oric now has access to both versions of the BASIC ROM and picks between them based on the static analyser's recommendation.

Fixed off-by-one recording of disasssmbled addresses; added logic to the Oric static analyser to try to guess between BASIC 1.1 (the preferred option in a tie-break or if no information is found) and BASIC 1.0.

In theory that's a full disassembler, at least as far as I want to go for now. Time to test.

Started fleshing this out; addressing modes are completely decoded, along with a bunch of opcodes, but appropriate address advancement isn't in yet, and neither is filling in derived metadata.

Implemented better sync-to-zero and discovered a header counting bug plus, probably, a misleading representation of gaps in the Oric TAP decoder.

Had a quick go at using the Oric parser for static analysis. Found out that synchronisation is lost. Need to investigate.

Shifted ownership of PETSCII -> string conversion down to the storage layer, where it's useful for tape parsing.

|
Started relocating the tape parsers down from static analyser to storage, to signify that they may be used by the emulation (if fast loading is supported on that machine).

The parsers no longer own a tape, merely taking one as an argument. So they can be an adjunct.

Implemented typer for the Oric, and I'm starting to think the code is a bit too repetitious. Refactoring will be forthcoming. Added CLOAD"" as the loading command for all Oric software.
