A little optimization for Z80 Assembler

2021-12-20T10:32:11Z

SagaDS:

So, you want to optimize your assembler code a little bit ?

Here are some "generic" ways to speed up / shorten your Z80 progs a little bit:

* CP 0 -> OR A
* LD A,0 -> XOR A
* CALL nn : RET -> JP NN
* BIT 0,A : JR NZ,n -> RRA : JR C,n
