Is there any available doc about the sound part ?
The more I dig, the more I found it's not like explained.
For exemple, I found on the BIOS (0x3384) that you CAN directly write to the PSG registers from the CPU.
It's not mandatory to use a Z80 subcode to do so....
Of course, it's slower and wastes ticks but I found nothing about it for now
