About APU emulation

[Boolean]

Hi, everyone.
I implemented graphics emulation using Win32 CreateBitmap and BitBlt functions successfully last year, though stupid.
Now, I intend to use Win32 waveOutXXX functions to implement sound.
I have learned about APU registers and am going to implement square1 & 2, but I don't know how to start it.
Help please

First, do you know how to generate a square wave? Try opening waveOut and filling the buffer with a hundred +4000 values, then a hundred -4000 values, then repeat.

Thank you.
I made it.
