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.

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.

It's just RTI and correct decimal SBC left of the official 6502s now, I think.
