I got it working by info in this other thread:http://www.fpsece.net/forum2/viewtopic.php?f=39&t=2664&hilit=heart+of+darkness
Enabling spu sync. I read this before, but it didn't seem to take unless I save the setting as the default and reload. Does this setting affect other games and am I correct taht settings must be saved to take effect?
Also this other thread says he couldn't switch to disc 2. Does this support multi-disc games or is it an issue with heart of darkness?
It works with Phaedrus Nine advice but problem is that impossible is continue game on with second cd ((( I hope someone will fix that
