OK, so my memory isn't too hot. Given that this code will probably execute in screen time, is it quicker to do:
LD A, (HL) = 7 cycles AND &EE = 7 cycles LD (HL), A = 7 cycles or RES 0, (HL) = 15 cycles RES 4, (HL) = 15 cycles NB The "cycles" here are raw z80 figures. Obviously on first glance the first method is 9 cycles quicker... but IIRC ASIC contention slows down memory access, the question is how much? It seems that method 2 runs quicker. I'd like to know why :) Cheers G
