Sorry for the wait I should be on this in the next couple of days I have mostly finished what I was doing though (that I was re-compressing/renaming my Dreamcast GD-Rom set that has taking an age to do) it is still missing a few files but not many now, but at the moment I can't find any public shares with the updates to the set and not is any great rush to get that sorted either to be honest.
This post is more of a reminder for myself to look at this next
EDIT
Finally got round to a test of this and seems to work just fine (though only let the demo mode play though due to not having a pad plugged in), you need to use ePSXe SPU Core instead of D-Sound
Sound drivers that work with CDDA are:-
ePSXe SPU core
Eternal SPU Plugin (Lite and Full)
Sound drivers not working with CDDA are:-
Ion's DirectSound Driver (Lite and Full)
Kazzuya DirectSound Audio driver
P.E.Op.S Dsound audio Driver
Seal Audio Driver
Not much choice there to be honest, I found that the ePSXe SPU core produced the best sounds
Myself if I was to emulate this game would be via an Arcade emulator instead of a PSX emulator
