Actually, I myself, find the rom calls easy, but some of the z80 language is
alien to me. But that's mainly due to me not having too much experience with
programming with other lower level languages. (and Yes I should get off my
butt to learn the z80 language, but at the moment I don't have the time).
But that's just me.
