Update to bsnes v025r10? release.

Yeah, even if we still don't have the S-DD1 100% understood, we can at
least get all known software working properly. And now we at least
have all the registers understood, just the edge cases that need to be
tested. I'm honestly glad I was incorrect in that the original patch
worked on hardware. Given it will never be updated again, this means I
won't have to get bug reports from now unto infinity about it.

 I posted a new binary WIP. If anyone wants to play through a few
levels of SFA2 or dungeons in SO and look for corrupted graphics, it'd
be appreciated. I'm sure it'll be fine, though. Oh, and the speedhit I
reported a few days ago was wrong. The old builds ran at the same
speed. Seems I have a ~6-8fps variance in that game per reboot.

 New WIP also starts the BS-X mapping. You can map in a cart now, but
it immediately freezes because the flash I/O registers do not respond.

             ---

             Also, I'd like to get serious about emulating the
SPC7110. But to do that, I need custom-made hardware.

 I asked someone about this already, but I may as well throw it out
there publicly in case anyone else would like to help.

             Here is the PCB for one of the SPC7110 games:
             http://nsrt.edgeemu.com/INFO/chip-pix/SPC7110.JPG

 What I would need is for the top two ICs to be desoldered, and socket
IC connectors to be placed on them instead. I would also obviously
need lots of compatible EEPROMs to connect to it (just two would
suffice, more would be better as it's quite possible I'd wear out the
write cycles with lots of intense testing, or bend up the pins like I
usually do when removing socket ICs).

             I would also need software+hardware to actually flash the
EEPROMs, as I don't have anything like this presently.

 More complex solutions, such as a ROM emulator with a parallel/USB
interface to the PC would be acceptable as well. So long as it's
something I can reprogram at my relatively low skill level.

 One cart would suffice, but again, the more carts the better in case
of failure. And I'd also like to see about sending one to another
person who's been interested in the SPC7110 for a while. So, three or
four preferred.

             I can supply the cartridges and money for time +
shipping. I'd prefer someone who _knows_ they can do this well try, so
that we don't ruin any unnecessary cartridges and so that the test
cartridges are as durable as possible. Especially since they most
likely won't be encased anymore.

             So, any takers?
