454c8628c3 Implemented an additional constructor for RegisterStates, pulling it out into file-level scope and implementing Equatable. 2017-05-23 22:05:33 -04:00
Thomas Harte
a23a6db4d6 Tidied up, creating a holder for RegisterState and giving it deserialisation logic. This makes sense because a register state will also need to be taken from the outputScanner, and from the machine. 2017-05-23 08:13:24 -04:00
Thomas Harte
6575091a78 Fixed Z80's ownership of its fetch-decode-execute program, its habit of scheduling invalidly when hitting an unrecognised operation and the test machine's habit of dereferencing invalidly. 2017-05-22 21:50:34 -04:00
Thomas Harte
9e25d014d2 Made an attempt to log bus activity for comparison with FUSE results. 2017-05-22 19:49:38 -04:00
Thomas Harte
41d5dd8679 Added a memory access delegate to the Z80 all-ram processor, to allow access patterns to be captured. 2017-05-22 19:24:11 -04:00
Thomas Harte

Thomas Harte

Thomas Harte
5dcfd85642 Added a compact and copy stage for instruction pages, both [mostly] eliminating the mistake of letting static data structures contain pointers to instance storage and opening the door for addition of the DD and FD pages. 2017-05-21 19:15:52 -04:00
Thomas Harte
c70dfe1b09 Implemented the two variations of loading between (nn) and SP. 2017-05-21 13:20:28 -04:00

Thomas Harte
