I've never used GBAGuy's tutorials, but the general consensus around here is that they're no good.

Check out the link on NESDEVWiki for the APU:

http://nesdevwiki.org/wiki/index.php/NES_APU

It is mainly based on the following document:

http://nesdev.com/apu_ref.txt

This document also discusses sound:

Hope that helps!

I'm getting blank pages back from nesdevwiki.org.

tepples: The wiki is working for me.

cea-six: Also, take a look at the NES101 tutorial on the main NESDEV page. I really like it, and it does show you how to generate a simple square wave tone.

Good luck!

It's working for me, but only as an anonymous user who is not allowed to edit. I've taken further discussion to the appropriate forum.
