First of all, thank you for your report, sir.

It occurs because of optimization fault of Visual Studio (2008). I can prevent 
this
regression by putting '#pragma optimize("", off)' at the top of cpu.cpp. 
However, I
think it's not a real fix, so I'm investigating what line causes such a strange 
issue.

For now, use revision 61 instead of the latest one. The difference isn't so 
large.

The cause is in memmap.h, it seems.

More accurately, getset.h

I don't know why, but the glitch occurs because of S9xGetWord. To help 
investigating
for the details, I dumped the optimized assembly by using code listing option of
VC2008. http://pastebin.ca/1589620

I fixed the issue in revision 69 without hacky optimization switch.
