Paula Emulation

[AmiBoy]

Hi All

This is just a quick question about how hard it would be to emulate/pass through Paula audio through a soundcard. Im not talking about emulating AGA as a whole just the Audio. Paula was not that specialsied sound chip was it?
This is just for those games that are RTG compatible but not RTA e.g. Payback and The Shadow of the Third Moon

Thanks
Mark
