Dark Cloud freezes on boot as of r547

[GoogleCodeExporter]

This issue is in response to a problem reported by Arcum42, starting with
r547, where-by Dark Cloud hangs during boot-up.

I have attached two patches, one or both of which are likely to fix the
problem.  I'm interested to know what the exact cause is however, so I
would like for the first patch tested first and then the second patch *if*
the first fails to work.  (if the first patch works then the second will
certainly work since it is a combination of the first patch plus extra
rollbacks).

My hunch is that the problem is the EE's counter exceptions, the vsync
exception in specific.  I have encountered some problems with
immediately-handled vsync exceptions crashing games and at this point I
haven't the foggiest clue why.

Try the patches and let me know the results.  :)

I'm on my way out the door, but wanted to let you know that I tried both 
patches.
Unfortunately, neither seemed to do it. And I also checked over my settings, and
verified against a copy of 546, just in case I was misremembering where the 
break was...

Freeze up should be fixed for now, although I don't like the hackish nature of 
the
fix very much.  Seems like there's something amiss in the exception handler, or 
some
instruction that's supposed to be disabling interrupts.  I'm not sure which.
