Log Message:
Update to 0.4.3. Compiles again on -current.
TODO: /dev/dsp needs to be replaced, haven't got around to that
yet, feel free to do it (simple SUBST* should do it).

Changes:
0.4.3:  (Note:  PCE CD save states created in previous versions will not work 
very well with this release)

        Fixed a compilation problem in cdromif.cpp regarding NULL on *BSD 
platforms by including <string.h>.

        Lynx:  Fixed the constructor and destructor declarations of the C65C02 
class, which should fix a reported
        compilation error with gcc 4.1.

        GBA:  Added a few missing variables to save states.

        GB:  Lines during which time the screen is turned off are now 
cleared(fixes flickering problems at the
        start of games, and during transitory blank screens).   

        Fixed the SDL_net.h include statement in drivers/netplay.cpp.

        PCE:  Fixed a bug with CUE+BIN sector size handling with regards to 
pregaps.  CUE+BIN is still
        officially unsupported. :B

        PCE:  Noise is now rendered at blip_med_quality.

        PCE:  Removed the code that checks to make sure the audio sector to 
play is non-zero.  Fixes "Crazy Hospital".

        Changed the maximum supported playback rate from 96KHz to 48KHz, to be 
able to safely extend the temporal precision 
        of Blip_Buffer further.
        Note that this shouldn't be considered a regression, as there are 
virtuall no benefits to using a sample rate
        above 48KHz in Mednafen(though there may be benefits in other 
applications).
        ***************
        ***BIG NOTE:***  
        ***************
        If you previously set the playback rate above 48KHz, you will have to 
manually edit the text configuration
        file(~/.mednafen/mednafen.cfg) to bring the value in range.  This is 
necessary because of a limitation in the setting
        validation code.


        Updated to Blip_Buffer 0.4.0, which offers improved sound quality over 
previous versions:
                - Improved sound quality by rewriting library to use 32-bit 
internal sample
                buffer, higher phase resolution, and a properly windowed filter 
kernel. Current
                user code should work without changes.

        PCE:  When sprites and background are both disabled, and the VDC is not 
in burst mode, the scanline is now filled with color 0x000 from the palette
        rather than 0x100.  This fixes the "Hurry Up" water effect in the CD 
game "Rainbow Islands".

        PCE:  Fixed the CD-DA amplitude calculating(used the BIOS' CD-DA player 
interface).

        PCE:  Altered VDC line timing slightly.

        PCE:  ADPCM frequency is no longer reset on ADPCM reset, fixes Gulliver 
Boy's dialogue voices during
        gameplay.

        PCE:  Fixed reading from nonexistant audio sectors(by memset()'ing the 
audio buffer to zero).

        PCE:  Implemented sector reading delays, games that use FMV like 
Gulliver Boy work much better now.  It's not implemented 100% correctly,
        and requires a small CPU hack to disable IRQs during a timing-sensitive 
period of emulation.  I don't like hacks, but...it's still better
        than the giant hack of reading all the sectors at once, which was how 
it used to be.

        PCE:  Implemented ADPCM read and write delay.  "Record of Lodoss War" 
no longer locks up at the title screen.

        PCE:  Opcode and operand data reads from VDC register 0x1 will now 
return 0x40, which fixes
        Dragon Slayer 2.  I doubt this is correct, but it shouldn't break any 
other game.

        PCE:  CUE+BIN audio playback no longer locks up the emulator, but 
CUE+BIN is still
        officially unsupported.

0.4.2:
        Fixed sprite hit emulation, fixes problems with VS Duck Hunt and VS 
Hogan's Alley
        that have existed since Nintencer.

        Modified VS Unisystem light gun emulation slightly to be more accurate.

        Fixed the in-emulator sound(nsf,gsf,hes) player's waveform 
visualization,
        broken in 0.4.1.

0.4.1:

        Joysticks initialization is now slightly more verbose.

        Fixed hash calculation in the joystick code, and added a workaround for 
hash
        collisions(which would occur if two extremely similar joysticks are 
used on 
        the same system).

        Video initialization is now more verbose.

        The -<system>.special command-line arguments for selecting a special 
scaler now
        take the short name of the scaler, which is found in the documentation, 
instead of
        arbitrarily-chosen numbers.  However, out of the goodness of my cold, 
black heart,
        arbitrarily-chosen numbers may still be used, though it should be 
considered deprecated.
        Example:
                -nes.special 1  (deprecated, but works, selecting hq2x)
                -nes.special hq2x (good!)
                -nes.special wombat (bad!)

        libsndfile is now used for WAVE recording(instead of the old ugly code).

        Altered the internal floating-point format used to represent audio data 
by changing
        the range to -1.0<=sample<=1.0(previously it was 0.0<=sample<=1.0).

        NES:  Fixed a 1-byte overflow bug in the Barcode World input device 
emulation
        code by changing a strcpy() to a memcpy().

        Added a "-help" command-line option, which prints out command-line 
arguments
        and parameters.

        Fixed the configuration file loading code to exit the emulator if
        invalid data is in the configuration file, instead of just ignoring it
        and the rest of the entries, thus trashing the configuration file on 
exit.

        Changed the default xscale and yscale settings for Lynx to 4.

        Physical mouse buttons can now be assigned to virtual buttons.

        The width and height of the state preview are now saved in save states, 
fixing a problem with broken
        save states if the -nes.clipsides option is used, and possibly in other 
situations(note that this 
        won't fix the problem in old save states, only new ones).

        Fixed a garbage(OSD stuff) problem in screen snapshots and save states 
when they are done after a frame
        that has been skipped(the solution is to delay the snapshot/save state 
until the next frame, which is
        set to not be skip).

        Fixed a typo that broke the hq3x effect(it had weird graphical 
glitches).

        Modified more settings to use the new plain-text configuration file 
format.

0.4.0:
        Various minor code changes I forgot to document.  I hope none of them 
are of the Mednafen-exploding
        variety. ;)

        Added support for saving and loading settings in a plain-text file 
format, and moved many
        settings to use this code.  This file is named "mednafen.cfg" in the 
Mednafen base directory(whereas
        the old binary configuration file is still named "mednafen03x.cfg").

        NES:  Merged RDoPCM() into RDoNoise(), reducing CPU usage slightly.

        NES:  Removed the pedantically high-quality sound mode, and reduced the 
filter order for downsampling
        from 512 to 256, with a larger transition band and smaller passband, 
creating a somewhat subtle low-pass filter
        effect on the audible portion of the signal, and decreasing CPU usage.

        NES:  Made optimizations to the CPU and PPU emulation code.

        PCE:  Added -pce.forcesgx, -pce.ocmultiplier, -pce.nospritelimit, 
-pce.cdbios, -pce.cddaquality, and -pce.compressor
        command-line options

        PCE:  Sound(excluding CDDA in CD emulation mode) is now passed through 
an audio volume compressor.

        NES:  Zero-page and stack memory accesses now go through the normal 
read-write function pointer system.
        This will increase CPU usage slightly, but it's important for future 
plans(readding cheat support,
        and an enhanced sound system through OggVorbis and WAV files).

        Updated to Blip_Buffer and Blip_Synth 0.3.6b1.

        Added special gcc options to configure.ac to get gcc to actually inline 
many functions
        that are specified to be inlined.  Sometimes I wonder if gcc developers 
are sane...

        NES:  Fixed a weird typo(with apparently no effect) in the B2005() 
function in ppu/ppu.cpp

        Fixed scanlines effect when using a special scaler.

        Lynx:  Optimized the sound rendering code slightly.

        PCE:  Added PCE CD emulation.

        NES:  Fixed the AMD64 MMX sound downsampling assembly code.  This bug 
fix fixes staticy sounds and other problems
        with NES audio on AMD64 platforms(only in 64-bit mode, of course :)).

        Removed MDFND_UTF8fopen() and MDFND_UTF8gzopen(), since they weren't 
really doing anything useful, and
        the same functionality could be provided more easily with some kind of 
wrapper library, if it's needed
        in the future.

        Updated the ZIP-file handling code with the newest version available, 
1.01e.

        GBA:  Updated most of the GBA emulation code with newer code from VBA's 
CVS repositoy.

        MDFN_FastU32MemsetM8() no longer tries to use floating-point data 
types, which was causing very bizarre problems on x86_64
        targets when compiled with gcc 4.0, and was probably an illegal thing 
to do anyway, as far as
        portability is concerned(or maybe gcc 4.0's autovectorizer is broken).
        This fixes problems with many GBA games when Mednafen is compiled with 
gcc 4.0.

        Added code to check for SDL_net in configure.ac and error out if it's 
not found, instead of blindly
        trying to compile.

        A negative result for the JACK test in configure.ac will now print the 
result "no".

        Removed the argument to AM_GNU_GETTEXT in configure.ac, effectively 
setting it to "no-libtool".  This will
        force a static library to be made when necessary, instead of a shared 
library, which should fix problems
        some people have been having with missing shared library error 
messages(libintl.so.3 and libintl.dll, for example).
