[ Help Needed ] Programming sound effects

Hi, im a great fan of MAME and the 1980's games.
Ive been working on a small game project using a PIC microcontroller and decided to add a sound output so have written a 3 channel square wave PWM tone generator that is functionally similar to the AY-3-8910/8912 sound chips used on many of the older 1970-80s mame games with the exception of the noise channel which I may include at a later time.
The sound works very well but the problem I have is creating sound effects tables that actually sound good (a real pain in the ....), after a few experiments I realize that the programmers of the 80's must have had a hard time creating these and I am amazed at some of the effects they managed.
What I was wondering is that if anybody knows if any of these game sound data tables have been dumped to file so that I could study them or possibly use them with my sound code or if not then a list of sound locations would be fine and I could dump and examine them myself.
I hope that someone out there knows of a link.
Thank You all at mameworld

Ive had an idea how to do this and hope someone can possibly help me
I think that if I patch the mame source to dump the 8910 psg registers to a file during game play then this will give me exactly what I want, tables of sound effects data
Anybody have thoughts on this ?

You'll have to capture the timing too.
