Update to bsnes v033r09? release.

New WIP, probably not worth downloading.

For the sake of completeness, I finished optimizing the SPC7110 code.
I've converted the pixel buffer rotation from swaps to moves, which
should double the speed of the slowest part. I've also added reverse
morton lookup tables (2x8-bit and 4x-8-bit deinterleaving), which are
8-10x faster than doing it using pure bit logic, I removed the
redundant comparisons from the pixel context lookup (though a compiler
would've done the same anyway), and lastly I've cut the mode2 context
table in half, since the refcon add bit was only set on context 1
anyway. I could've replaced the other half with 5-6 if/else
statements, but I didn't see much of a point in that since it'd only
make the code harder to understand.

That results in a 1-2fps speedup, at best. Really, the code is simply
not a bottleneck. It's pointless to optimize anymore, as any changes
from this point on will just make it harder to understand what's
happening. I only added the morton tables because it does seem to aid
readability.

Also added translate[] wraps around all the new status messages, and
moved the two checkbox options on the paths window to the advanced
options list. No sense cluttering up the UI with near-useless
settings.

Heh, yeah. I never understood the floating point multiplier setups in
some emulators. I guess it's useful if you want your video output size
to be π x _e_.

I thought about the "Are you sure?" thing, it'd be nice if you
accidentally close the emulator, so you don't lose your save. But I
quickly realized that despite using emulators for ten years, I've
never _once_ actually done that. The only point where it might be
appropriate is if I add mouse / SS support, since you may want to have
the cursor near the top right of the window with the menubar off in
windowed mode (though you're just asking for trouble at that point,
honestly.)

To be fair though, you helped design at least half the bsnes GUI, so
obviously you should like it :P

Super Power League 4 seems to die after an inning or two with a S-SMP
crash. I still need to try screwing with the CPU/SMP scalars and try
substituting with anomie's DSP core to see if it still dies. If
neither of those affect it, it could very well be due to a timing
issue with not emulating the delays of the SPC7110 chip or something.
If someone wants to rule out the DSP core, they could try playing a
SPC dump from the game in one of the plugins that use blargg's core. I
doubt it's that, personally.

The usual rules about special chips apply, but you can list it as a
bug if you like. I probably will with a note. Maybe I can figure it
out before release. Probably not, but who knows.

Sigh, it's always the god damn baseball and golf games, isn't it? I'd
probably half-ass the game too, if it were my job to work on one.

Ah, thanks. Updated the license file. Decided against listing all the
libraries there for now, as they're getting quite numerous.

As for credits, mudlord is already listed in the source file, and the
contributors list is for people who have submitted code to the core of
the emulator. It's not a good system, I admit. That obviously excludes
you and tetsuo55, despite the fact that your testing has been one of
the most helpful things I've received.

It's not that I mind listing people, but I don't want that window to
become cluttered with 100+ names of everyone up to and including
people pointing out spelling mistakes in WIPs. That would make the
window really onerous to look at.
I really don't want to come off as rude here, I'm really truly
grateful to everyone who has helped out even a little, and I'm happy
to thank them all in some perpetual fashion (eg website thank yous
tend to disappear as the news falls off the page.)

That's the second time someone's brought that list up. I was afraid
that adding such a list would just end up causing problems. Maybe I
should just remove the contributors list on the about screen, and put
everyone in the readme.txt file, so that everyone who ever contributed
anything is listed?
