Emulating a CPU in C++ #22 (6502) - ADC Addressing Modes

In this video i implement tests for ADC (Add with Carry) to get the rest of the addressing modes working. I also do some tidy up and refactoring of the code from the previous episode.

I suspect that you should be a salesman for GTest. Because you have sold it to me with this video.

7:33 pretty sure you're writing Verilog HDL at this point, with conditionals like that! 🤣

Neat refactoring of the refactoring

[@dbaznr]

Grate job! Perhaps should be better update the A REG using a propriate sub, avoiding so the redundant code about setting FLAGs.

[@jorenheit]

Don't you need (Condition) in the macro? Now it will evaluate to !Flag.D == false, when you meant !(Flag.D == false). Works in this case, but will fail for more complicated conditions. Or did you fix this later perhaps?
