8c0e06e645 Adds a test for 0x83 and fixes sign extension.

 2021-01-10 22:55:25 -05:00
Thomas Harte
9ba5b7c1d4 Adds a few more asserts.

Thomas Harte
a15af1df5e Attempts to use the other bit of disk drive control, the 5.25"/3.5" select. 
For the record, the ROM thinks it finds some Smartport devices and then attempts to talk to them. Since none is present, it blocks forever.

bdda84dfde Adds a very basic shadowing test. 
For the record, I'm aware that there's a lot here that I'm not testing. I think the smart move is to get towards a running machine and see which configurations it actually tries to set up, then follow along with appropriate testing; it might cause me to discover a flaw in my comprehension before I've made the same mistake in both the code and a test.

1653abdf88 Adds the .lst; otherwise I'll probably just lose it. 2020-10-19 20:58:24 -04:00
Thomas Harte
b3ab9fff9b Imports a custom-built copy of Klaus Dormann's 65C02 test, with only 65816-compatible parts. 
Thereby fixes another couple of 65816 issues — BRK(, etc) not clearing the decimal flag, and `TRB d` being mismapped.
 2020-10-19 19:27:16 -04:00
Thomas Harte
99eba2f8ba Ensures intended 65816 exception behaviour. 
i.e. the relevant micro-op sequence exists, and its operation isn't lost. Also sets the 65816 by default to jump straight into power-on, not to execute an instruction first. That shouldn't make a functional difference, but it makes debugging easier because it makes startup fully deterministic.

0418f51ef2 Takes a shot at emulation-mode 'exceptions'. 
It's just RTI and correct decimal SBC left of the official 6502s now, I think.
