how to reflect a byte's bit-pattern in assembly?I'm trying to use 16 pixel-wide graphics which are symmetrical around the vertical, i.e. if the left byte is 01001110 the right byte will be 01110010…
I remember that when I started to learn Z80 assembler, I believed there must be a single Z80 instruction that will mirror the byte just like CPL inverts 0s and1s.
It was dissapointing that I had to do it myself :) -
