It's funny you used the single-instruction block move as an example. The successor to the 6502, the 65C816, does have a single-instruction block move. Actuall

It's funny you used the single-instruction block move as an example. The successor to the 6502, the 65C816, does have a single-instruction block move. Actually it has two, one for when you want to move from the top down, and another when you wnat to move from the bottom up (in the case where regions overlap).
