I got the game to run and the music plays fine thanks to VDMS. But when a character talks sometimes I can hear the voice and sometimes I can't; and, when conversation or an action is initiated the loading cursor hangs a bit before the game resumes. Seems to be sometype of random lag. I have no idea how to fix this and would greatly appriciate some help.
