3f880fa769 Fixed [FD/DD][74/75], which always store H or L, never IXh, IXl, IYh or IYl. 2017-05-29 11:44:26 -04:00

d83dd17738 [DD/FD]36 turns out to be a timing error: offset calculation overlaps with value fetch. So the FUSE test was cutting off my implementation early. Fixed. 2017-05-29 11:40:56 -04:00
Thomas Harte
9ade0dcae3 One failure was just PUSH AF due to throwing away the 5 & 3 flags at the start. Switched to throwing them away at comparison. 2017-05-29 11:06:23 -04:00
Thomas Harte
a329d85697 Instituted memory value checks, flushing out seven new failures. 2017-05-29 11:01:45 -04:00

c322410783 Corrected CP[I/D]R termination logic; all tests now passing to the extent of interrogation. 2017-05-29 10:52:54 -04:00

Thomas Harte
a47b339668 Made an attempt at OUT[I/D]R. 10 failures remaining. None of which, I guess, are due to unimplemented operations. 2017-05-29 10:28:04 -04:00

Thomas Harte

Thomas Harte
76f03900d2 Implemented EX HL, (SP) so as, allowing for indexed pages, to bring issues below the psychological 100 barrier. To 99. 2017-05-28 00:02:14 -04:00
Thomas Harte
035df316aa FUSE seems to have inconsistent ideas about where b3 and b5 come from in more-complicated BIT instructions. So I'm not testing them for now. Within that reality, reduced to 102 failures. 2017-05-27 23:54:53 -04:00
Thomas Harte
9759a04c7d Timing fixes: the fetch-decode-execute pattern is now per-page, since that on [DD/FD]CB not only doesn't increment R but doesn't take four cycles, so is probably a normal read cycle. Adjusted timing all around. 2017-05-27 23:54:06 -04:00
Thomas Harte
c7cb47a1d8 Readded and then disabled my temporary one-test-only patch. Failures are currently at 237. 2017-05-27 21:10:25 -04:00

0d2d04e17b Seeking proper [F/D]DCB emulation: the offset comes before the final byte of opcode, and adding seems to overlap with the opcode fetch, which does not increment R. Also needs to duplicate the result to visible registers. 2017-05-27 21:06:56 -04:00
Thomas Harte
98423c6e41 Accepted FUSE's view of bits 3 & 5 from BIT and RES, reducing to 623 issues. 2017-05-27 16:19:15 -04:00
Thomas Harte
33c3fa21e3 Fixed (HL)/(In + d) CB page modify instructions. Reducing failures to 672. 2017-05-27 15:54:24 -04:00

151b09b5ca Fixed various other obvious cases for indexing. 2017-05-26 23:37:17 -04:00
Thomas Harte
9bc2b48d9b Found a form I like for indexed addressing, applying it only where obvious for now. Which eliminates more than a couple of hundred of remaining failures. 2017-05-26 23:23:33 -04:00

2cadc706e2 Now runs FUSE tests, albeit testing only a subset of the results. But enough to get started. 2017-05-25 21:00:33 -04:00
Thomas Harte
3c6f63abcc Started towards running the FUSE tests. Just need to deal with the memory segments. 2017-05-25 19:12:59 -04:00

00cd7e7e9c After hitting my head against the wall of trying to use [NS]Scanner as a parser some more, have given up and transcoded the two tests files to JSON. 2017-05-25 18:20:13 -04:00
Thomas Harte
055c860b43 Sealed off RegisterState as immutable, and started trying to parse the .expected file. 2017-05-23 22:32:36 -04:00
