Update to 0.8.C/0.8.12:

0.8.C:

        SMS:  Fixed the input and reset emulation when the territory was
        set to "domestic"(Japan) and FM emulation was enabled; the emulated 
system was erroneously
        being treated as a Game Gear in a few places when those conditions were 
met.

        GB:  Fixed initialization of "HRAM" on virtual power toggle/reset.

        GB:  Fixed a bug(still many left) in the external RAM handling code, 
fixing an
        emulator crash with "Wizards & Warriors - Chapter X".

0.8.C-rc1:

        NGP: Fixed an unaligned memory access bug in the memory r/w handlers, 
causing crashes on platforms
        that do not support unaligned memory accesses.

        NES: Fixed an intialization bug in mapper 193.

        Added define "ALWAYS_INLINE" to force the compiler to always inline 
speed-critical functions, and added it to
        many emulation functions in that category.  gcc can be a pain in the 
butt.

        GBA:  Fixed a bug that would cause data corruption and the loaded game 
to crash whenever a state was
        saved(but the state itself, and loading it, was fine) on a big-endian 
platform.

        Fixed several instances of mismatches between format strings and passed 
argument types, which could cause
        nonsensical information to be printed on big-endian platforms, and 
perhaps some little-endian platforms as well.

        Fixed the minimum field-width specifier on the statements that print 
the loaded game's CRC32 in several
        places.

        Added the "format(...)" function attribute to the MDFN_DispMessage(), 
MDFN_PrintError(), and MDFN_printf()
        function prototypes to catch format string errors.

        Fixed the order of the sound drivers in the documentation(it was 
erroneously implying that OSS had a higher
        priority than ALSA for the default sound driver), and added various 
notes to explain the sound drivers.

        If an invalid "sounddriver" is selected, Mednafen will now print an 
error message and not initialize sound
        instead of silently selecting the default sound driver.

        SexyAL: Altered the argument order of SexiALI_Convert() to make more 
sense.

                Fixed the broken conversion code used when the frame count 
passed to Write() is greater than 2048.

                Fixed a bug/design flaw in the SexyAL SDL sound driver that can 
cause a crash during program
                deinitialization.

                Added support for "float" output format to the ALSA driver.

                The ALSA driver will now try all formats that SexyAL's 
conversion code supports if the desired
                format is not supported by the output device, rather that 
simply erroring out as before.

                Added support for converting to 24-bit and 32-bit PCM output 
formats from the source format(which
                is still fixed to signed 16-bit).

                The driver function RawCanWrite() is now passed a pointer to a 
uint32_t, which it sets to the number
                of bytes that can be written without blocking, rather than 
returning the value directly, so that
                the return value can be used as a success/failure indicator.

                The driver function RawWrite(), and the "user" function 
Write(), will now return 1 on success, 0 on
                (fatal) error, rather than returning the amount of data written.

                The OSS driver was testing the return value of open() 
incorrectly.  Fixed.

                SexyAL is now compiled as C++(but doesn't use many C++ features 
yet), which necessitated
                adding several explicit casts in various code, and fixing some 
inconsistent function prototypes and
                declarations.

                JACK: Fixed a stereo playback crashing problem(a loop count was 
being calculated incorrectly).

                JACK: Switched to using jack_client_open() instead of the 
deprecated jack_client_new().

                JACK: The "sounddevice" setting is now used, to specify the 
JACK server to connect to.

                JACK: Fixed a possible race condition in RawCanWrite().

                JACK, SDL: Changed the inter-thread ringbuffer setup to be less 
likely to underrun, while not hurting
                latency.

                JACK, SDL: Additional playback position precision is now 
obtained by using
                jack_get_time()/SDL_GetTicks().  This will improve Mednafen's 
performance with larger fragment sizes
                with these drivers, but smaller fragment sizes are still 
preferred for latency-to-underrun-occurrence-ratio
                reasons.

                Renamed the "byteorder" field of SexyAL_format to 
"revbyteorder", and changed it to a boolean type,
                to avoid confusion over what it actually represents.

        Removed erroneous dependency on CD-ROM emulation when WonderSwan 
emulation is enabled in the configure script.

        Added sanity checks to the first track number and total track count 
returned from libcdio, to prevent
        a crash in Mednafen if the libcdio driver fails and returns nonsensical 
values.

        Removed unused file sms/state.h

        Fixed a very-old bug that caused joystick unique ID collisions if more 
than 2 of the same "type" of physical
        joystick were available.

        Fixed a string constant-to-(char *) problem in sms/romdb.h.

        Mednafen is now compiled with -fsigned-char, to prevent any potential 
problems on systems with an "unsigned" char
        type as default.

        The included Tremor is now compiled with "-fvisibility=hidden" to work 
around a dynamic symbol collision
        problem with libsndfile(BUT, -fvisibility is only available in gcc 4.0 
and newer).
        This solution may not be correct...

        Updated Tremor to the latest SVN version.

        PC-FX:  Added a semi-hack to fix a missing background layer problem in 
parts of "Angelique Special".  The
        underlying problem(no emulation of the programmable BG0 subscreen) will 
be corrected in 0.9.0.

        PC-FX:  Removed the unused V810 cache structures(Mednafen 0.9.0 will 
feature cache emulation, however).

        PC-FX:  Added a few CPU variables to save states whose absence could 
have caused netplay/movie desynch.

        PCE:  Fixed virtual power-toggle initialization of VCE and gamepad 
input variables.

        PCE, PC-FX:  Fixed the emulation of SCSI command 0xDE, mode 0x1.  The 
value returned was too small by
        2 seconds.

        PCE, PC-FX:  Fixed the sector count for the last track(which influences 
the leadout track start position/total
        sector count) in multi-track CUE/BIN CDROM images.

        PC-FX:  Fixed the handler address called when a TRAP instruction is 
executed.

        PC-FX:  Fixed the exception code set when an FPU divide-by-zero 
occurs(previously, it was being set to the
        integer divide-by-zero exception code).

        Fixed several problems in file.cpp, including buggy and 
overly-complicated MDFN_read*le() functions,
        and a problem with the const-ness of the return value of strrchr() with 
gcc 4.4.
