Thomas Harte
979186e71d Transcribes the English-language versions of the outstanding tests. 
Passing these will make me willing to call the 65816 functionality provisionally done, other than making sureI signal VPA, VDA, VPB, etc, correctly.
 2020-10-14 13:56:37 -04:00
Thomas Harte

Thomas Harte
6a47571d17 Stops truncating tests by two bytes. 
Not that it seems to have been problematic.

Thomas Harte
f529eadbec Corrects 16-bit read-modify-write. 
Subject to the TODO proviso on 'correct'; has my 6502 prejudice pushed me into unrealistic bus signalling?
 2020-10-12 18:36:09 -04:00
Thomas Harte
5dc3cd3a2f Starts using Jeek816 for a basic native-mode audit. Fixes absolute long addressing. 2020-10-11 22:02:46 -04:00

 2020-10-11 17:56:55 -04:00
Thomas Harte
8eaf1303a3 Attempts proactively to ensure proper RTI behaviour on the 65816. 2020-10-11 15:25:13 -04:00
Thomas Harte
20cbe72985 Ties to 8- or 16-bit those instructions that aren't M/X-dependent. 
This is technically redundant for PEI, PEA and PER since they have dedicated bus programs anyway, but it's good to be explicit.
 2020-10-11 14:38:35 -04:00
Thomas Harte
071ad6b767 I don't think RTL is needed; JML looks like it covers it. 2020-10-10 22:16:35 -04:00
