Switched to std::ostringstream to avoid the need to make a string length count (and I was one off when loading a disk).

Added an attempt to distinguish the MegaBoy (now with proper capitalisation) and a test for it.

|
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 |

|
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.
|
2017-02-26 21:24:54 -05:00 |

|
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 |

Extended quality of known address read/write/modify mapping, and started recording internal accesses in addition to external.

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

Ensured no attempt to call strcmp on null if a file name without an extension got into here.

|
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.

Dragged multibyte primitives and signature checks up to the base class. Implemented support for Oric MFM-style .DSK, at the file format level.

|
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.

ab64731d51
|
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.
