6688f83226 Took a shot at LDIR. 2017-05-20 21:58:24 -04:00
Thomas Harte
01a064dd63 Added an empty ED page. 2017-05-20 17:29:30 -04:00
Thomas Harte
7b234078ae Implemented EX DE, HL and shuffled to allow instruction pages. 2017-05-20 17:04:25 -04:00
Thomas Harte
add02a7897 Added LD (nn), A, and reduced double logging to single for now. 2017-05-19 23:13:28 -04:00
Thomas Harte
19167df692 Consolidated and filled in AND and XOR. 2017-05-19 23:03:34 -04:00
Thomas Harte
6766845e21 Filled in most of the loads. 2017-05-19 22:57:43 -04:00
Thomas Harte
bc3b5f3e35 Added 16-bit INCs and DECs. Which don't set flags, so are easy. 2017-05-19 22:13:36 -04:00
Thomas Harte
5fe23113ec Moved RET to the correct place, implemented POP AF. 2017-05-19 22:03:12 -04:00
Thomas Harte
c55e1c1d17 Implemented POP and therefore RET; corrected timing of PUSH. 2017-05-19 21:59:45 -04:00
Thomas Harte
eae1f78221 Implemented the main page pushes. 2017-05-19 19:28:38 -04:00
Thomas Harte
11d05fb3b8 Expanded a little on operations, added an implementation or two. 2017-05-19 19:18:35 -04:00
Thomas Harte
58efca835f Sought to add a further opcode. 2017-05-18 22:53:43 -04:00
Thomas Harte
99f2060fc1 Further improved macros. 2017-05-18 22:11:54 -04:00
Thomas Harte
5d3ebcb35a Made a first attempt at LD HL, (nn). 2017-05-17 22:42:30 -04:00
Thomas Harte
509d011fbe Implemented JP, my first Z80 operation. 2017-05-17 22:31:41 -04:00
Thomas Harte
17ffd604bf Made an attempt to get the Z80 at least as far as rejecting an opcode. 2017-05-17 21:45:23 -04:00
Thomas Harte
1378ab7278 Ensured initial program counter and stack pointer are correct for Zexall, fixed the Z80 to use a compile-time polymorphic call for bus access. 2017-05-17 07:36:06 -04:00
Thomas Harte
87a021ec2d Made further attempt to get as fas as having the Z80 attempt to do something. 2017-05-16 22:19:40 -04:00
Thomas Harte
d559d8b901 Continued edging towards getting the absolute basics of a testable Z80, for test-driven development. Corrected old-fashioned instance naming issues with the corresponding 6502 class and removed an unnecessary source file while at it. 2017-05-16 21:19:17 -04:00
Thomas Harte
50bb4f0142 There's finally a loop in here, at least. 2017-05-15 22:25:52 -04:00
Thomas Harte
7da51602d5 Moved flush, added run_for_cycles, which does nothing right now. 2017-05-15 07:59:21 -04:00
Thomas Harte
5152517887 Added the boilerplate stuff necessary to query registers. 2017-05-15 07:55:53 -04:00
Thomas Harte
eb8a2de5d6 Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80. 2017-05-15 07:38:59 -04:00
Thomas Harte
f2a1a906ff Adapted what negligible amount there is of the z80 as per the new CPU namespace. 2017-05-14 22:15:16 -04:00
Thomas Harte
0808e9b6fb Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair. 2017-05-14 22:08:15 -04:00
Thomas Harte
b81a2cc273 First tentative steps towards adding a Z80 implementation. 2017-05-14 17:46:41 -04:00
