[A83] Re: Quick quistion about djnz




Everyone says "speed is important", but very rarely is it really important.
If two t-states are going to be called 100,000 times a frame, then maybe
it's important, otherwise, no.  And in this case, it's not faster anyway:

 djnz label   ; 13

 dec b          ; 4
 jp nz,label   ; 10
                   ; = 14
