And I'd like to add one more, maybe obvious thing - you don't have to play music in interrupt routine
You can do it anywhere in your code, just do it during each frame. Some purists may say that if you call music player sometimes at frame beginning and sometimes at frame end then there would be loss of music quality. But I did it in my games before and nobody noticed and complained

The Z80 CPU will only detect a maskable (normal) interrupt when it samples the /INT pin at the end of an instruction (assuming that /RESET, /BUSRQ and /NMI are all inactive
Tut-tut. Use the Force (of BBCode), Mark. It’s
INT,
RESET,
BUSRQ, and
NMI.
Yeah, I know
But I composed this post off-line in a text editer. Then had to post in a rush, as channel 4's formula 1 coverage was about to start and I had a few other things to do before sitting down to watch it and eat lunch...

You humans are so weird. You watch TV and each lunch. So bizarre.
