I finally got around to running Klaus Dormann's 6502 functional test against the M6502A MPU model for py65. It passed all 6502 tests, including the BCD adc/sbc tests.
I did find two typos in the instruction dispatch table: (1) where I dropped the leading 's' from the python self object reference, and (2) where I somehow deleted '
ro_' from an address mode function call for
abs addressing for the
and abs instruction.
I don't know why I've procrastinated so long on running that code against my python processor model. I used to run regularly against my soft-core model. Guess I didn't want to debug any errors that those tests may have found.
I will have to assemble Klaus' 65C02-specific test routines, and run those sometime soon.
