the audio problem on Phantasy Star 2 is known about and is a problem with the source of Gens that is available. Apparently the audio code changed between the last win32 binary release and the release of the source.
There is a post about it on the Gens forums (gens.consolemul.com) follow the links to the forums and then the Gens development forum. Don't have a direct link to the post I'm afraid.
We'll probably have to wait for the main source to change before this issue is resolved.
Everyone else - thanks for the kind words - hope you're all enjoying the holiday season!!
