Emulator

I forgot to add that I'm using Windows 7 64-bit, sorry.

revision 5365 is what broke it.

Were you using the "RE0 hack" in the dsp hle plugin?

I was not.

iiinteresting...

I agree. I was surprised to see the contents of that revision when I found it to be
the one that caused the problem. I double-checked to make sure that was the right
one as well.

if you can compile, try changing this file back to the way it is on the left:
http://code.google.com/p/dolphin-emu/source/diff?
spec=svn5365&r=5365&format=side&path=/trunk/Source/Plugins/Plugin_DSP_HLE/Src/UCodes/UCode_AX.cpp

Then remove the line
int k = g_Config.m_RE0Fix ? 0 : j;
and replace the two instances of k with j

That fixed it, but I think the sound (which is already really bad) has gotten worse
as a result.

Ok, sound is definitely significantly worse with the change you had me make.
Hopefully some sort of compromise can be found.

I'm surprised it seems worse, since that's what was happening when you were running the game before revision
5365.

Worse than the head revision right now, I mean. Compared to revision 5364, yes,
there's no change.

Using Rev.5402 the sound is amazingly improved from prior versions, however it won't
leave the battlefield.
