What's New :
------------

v1.17, Win v0.85
      - Added slow-down key.  You can configure it in Misc -> Game Keys
      - Invulnerability bug of the 3rd boss in Demon's Crest in the
        good checksum roms is fixed through rom mirroring
        I also noticed that this fix is the same as what the author of
        SNEeSe told me before about on some MegamanX1 roms, but I never had
        that rom so I never added this until now.  Guess that rom
        is also fixed too.
      - Changed memory initialization values - Lost Viking 2 works again
      - 65816: Fixed WAI instruction timing with HIRQ's
        Top Gear 2 - 2 player mode works now
      - Improved IRQ re-execution timing precision
      - Starfox 2 beta now runs with sound!
      - Fixed flickering problem in Starfox 2 beta
      - Added Mode 2 16x16 tile offset per tile mode
      - (Win32) Improved the timestamps on UDP headers.  This should
        (hopefully) solve those out of sync (where both sides see different
        things) problems with certain connections (ie. T1/LAN connections) in
        netplay.
      - (Win32) Added a big notice in netplay.txt.  For all of you who used
        netplay and had poor experiences with a ping time of less than
        300ms, read it!  Also added a more realistic system requirements
        description for decent netplay in netplay.txt rather than a cpu
        speed estimate.
      - Changed reverse stereo method to become invisible to the sound
        registers in emulation

v1.14, Win v0.80
      - Fixed configuration files from removing spaces from directory names
      - (DOS) Fixed 640x480 vesa2 scanline+interpolation display problem
      - (Win32) Improved Windows speed in 32-bit windowed mode.  Should
        give around an 18% speed increase in FPS.
      - (Win32) More netplay improvements.  Shouldn't be as jumpy when
        one side lacks input.
      - (Win32) Starting netplay will now force the max frameskip to 3
        if it is less than it and also force on auto frameskip.
      - (Win32) MMX optimised netplay with back buffer enabled.
      - (Win32) Fixed load state in netplay to load properly instead
        of sometimes stalling for no reason
      - (DOS) Accidently deleted the code to initialize IPX.  Fixed now.
      - Fixed a configuration loading problem when loading ZSNES from
        a different directory.
      - (Win32) Attempted to fix those out of sync problems (although
        I don't know if it's fixed now since those problems rarely happen
        to me)
      - (Win32) Displayed the current filename in the load window
        for those files with extra long names.
      - (Win32) Added nickname support to NetPlay.  There's a 9 character
        nickname size limit.
      - (Win32) Added actions to chat (similar to how mIRC works - use
        /me <action> )
      - (Win32) Nicknames can be changed in the windowed chat by typing
        /nick <new nickname>
      - Added a small buffer to the in-game chat to allow up to 5 chat
        strings displayed at once.
      - Local chat strings now appear in that buffer
      - Thickened black borders on the 5x5 font
      - Extended in-game chat length by around 30 characters
      - Fixed up Interpolation

v1.12, Win v0.74
      - (Win32) Hopefully fixed up those green display bugs in
        scanlines/2xSaI in 1:5:5:5 16bit modes.
      - (Win32) Improved lost packet recovery time and reduced the
        number of lost packet stalls in UDP netplay (should produce
        more fluid netplay)
      - (Win32) Fixed up crashing bug in Tales of Phantasia with a 512
        byte header
      - Extended filename length of the Quick Menu
      - (Win32) Hopefully fixed up the mouse wheel support for certain
        mice
      - Temp .ZIP directory is now cleared if it exists prior to another
        .ZIP file being loaded.
      - (Win32) Improved DirectInput error handling

v1.11, Win v0.72
      - (Win32) ZSNESw won't crash anymore if you don't have a soundcard
        or if DirectSound fails to initialize.
      - (Win32) Fixed a nasty performance bug with certain types of
        joystick/drivers installed, causing the FPS to be slower for
        no reason.
      - (Win32) Wrote an MMX optimised blitter for 16bit non-D windowed
        and full screen modes.
      - (Win32) Added simple wheel mouse support.

v1.10, Win v0.70
      - Fixed games that turns on the x239 resolution (eg. Chrono Trigger
        battles) when scanline mode is enabled
      - (Win32) Fixed up crashing bugs on extra long filenames with
        underscores
      - (Win32) Hopefully fixed the odd colored interpolation in 1:5:5:5 16bit
        color settings
      - (Win32) Hopefully won't crash anymore when the temporary directory
        exists prior to unzipping a .zip file
      - (Win32) Fixed loading of .zip files with more than 2 '.'s in the
        filename.  Thanks to DCX for helping us troubleshoot this.
      - (Win32) Fixed up short filename saveram/save states loading when
        the long filename has spaces in it.
      - Added TCP/IP Support.  It is recommended that for playable netplay,
        you'd have an average ping time of less than 300ms (type
        ping <ip address> in dos) and that packet loss is minimal for TCP/IP
        (not UDP).  At the moment, you cannot have more than 2 connections
        Thanks for all the testers for testing this, especially DooMStalK,
        GreenImp, and TeleKawaru!  Also added back buffer support.  This
        will sacrifice cpu power for netplay to make it much more playable.
        WARNING: High cpu speed recommendations (~450mhz+).
                 Please see netplay.txt for details.
      - Added save states to netplay (just use them like you normally do)
      - Save Ram is now defaulted to load/save on the server's side
        Save Ram are not supported in SA-1/SuperFX games due to their size,
        but you can use save states instead in that case.
      - Increased chat line length in the out-of-game chatbox by a lot
      - Partly increased the chat line length in-game
      - in-game chat text now stays longer on-screen by 2 seconds
      - Added reset in netplay
      - Fixed up movie recording feature
      - (Win32) Mouse shouldn't get stuck on the left side anymore.
      - (Win32) Video mode 3 (256x224FS) shouldn't crash anymore.  Thanks
        to kode54 for his assistance on the above 2 bugfixes.
      - (Win32) Fixed the instability bug where the window can sometimes
        start shaking for no reason and takes away windows resources.
      - (Win32) Re-wrote keyboard character input routines
      - Fixed up FF2(4)'s music in lower sampling rates
      - (Win32) Coded in the UDP protocol as a replacement for TCP/IP.
        Some network configurations won't work with UDP.  However, it is
        strongly recommended that you use UDP if you can because of the
        speed increase.  In order to disable UDP and use TCP/IP, both sides
        must de-select UDP.  
      - (Win32) Added a small multiplayer game list (multi.txt)
      - Added an updated Windows FAQ, courtesy of TuxedoMsk of VGNetwork
        who updated it.
      - Added a more user friendly input selection routine (changed Direct
        Input to Keyb/Joystick and it also auto-sets keyb/Joystick when you
        set a key)
      - Hopefully fixed up the sprite priority problems (eg. FF2/4's
        damage points)
      - (Win32) Added rewind support for up to 8 levels (in 8 second
        intervals) (NOTE: Windows Port only! - Sorry DOS Port users).  In
        order to activate this, assign a key to the Rewind Key in the
        Misc -> GameKeys option.
      Note: Netplay plays really nice as long as the net connection is not
            unstable, both sides have a fast cpu  (speed requirements depend
            on the game), and at least have a 28.8 connection.
      *** PLEASE READ ZSNESW.TXT IF YOU ARE STILL HAVING PROBLEMS WITH
          THE WINDOWS PORT

v1.01 - Fixed a problem with offset per tile mode with MMX2 in
        the new 16bit engine
      - Fixed crashing problem in MMX2 (Win port)
      - Removed clock option (Win port)
      - Disabling the new graphics 16bit engine is now properly saved
        in the configuration files
      - Added the win port version number to the about box (Win port)
      - Fixed the % of execution problem in IPX/Modem modes

v1.000  - Implemented C4 emulation :
            - C4 Sprite structure -> OAM conversion routines
            - Sprite Rotate/Scale ability
            - Sprite disintegrate function
            - All in-game used math co-processor functions (hopefully)
            - Both wireframe modes
            - There are still some problems with C4 emulation, but I'd
              consider them to be quite minor to just leave them there.
            Thanks to StarCreator for recording a bunch of movies off
              of the real snes for me to compare!
        - Tweaked ADSR a bit
        - Decreased envelope when key on is issued while sound
          is still playing.  This fixed static/popping sound bugs that
          affected many games.
        - Added the ability to select the Add-on device
          (Snes Mouse/Super Scope) from the GUI through the Add-on option
          in the Config Menu
        - Added a hack to allow the mouse to control the cursor in
          Lethal Enforcers (Press '7' 4 times to activate or select
          it from the Add-on option in the Config Menu).  Unfortunately,
          this method has problems (ie. mouse moves things that it shouldn't)
          but it should be good enough, especially for those who asked for
          this.  I doubt this works in LE2, however.
        - Added a manual load entry box so that you can type in the
          filenames/directories manually or type in part of the filename
          and the GUI will seek to whichever filename contains or
          closely contains that part
        - Pharos coded a water effect, getting help from Scott Scriven's
          water effect code.
        - You can enable/disable the Water Effect and Snow Effect from the
          GUI Options (MISC Menu in the GUI)
        - Implemented Sprite Windowing to the new gfx 8bit engine.  This
          completes all the features that I have planned for that engine.
        - Fixed a really nasty stereo bug that caused volume levels/pans
          to sound completely off on one of the speakers
        - Added player 5 as a normal player instead of just being available
          in modem/ipx play
        - Implemented an option to turn in-game messages/fps display to
          be transparent
        - Added a Set Keys feature to the Input Routines in the GUI that
          allows you to set all of the standard SNES keys all at once
          instead of clicking on the inputs separately to set them
        - Ported the new graphics 8bit engine to 16bit:
            - All the standard snes features from the 8bit engine
            - Works with all 16bit resolution modes/effects
            - Ported high resolution Mode 7
            - Added proper main/sub screen support and windowing support
            - Added all transparencies modes
            - Added Direct Color Mode7
            - 2xSaI and 50/75% scanlines can now co-exist with high
              resolution modes
            - This is now the default engine for 16bit.  Some games won't
              work well with this engine such as some SuperFX games (eg. Stunt
              Race FX in the menus).  You can switch back to the old graphics
              engine by pressing the '8' key.
            - Implemented a dual cache system in the tile modes.  I don't
              know how much of a speed increase this gives since my system
              can already run the old graphics engine at full speed and
              framerate.
            - Full 15bit transparencies for MMX cpus only.
        - High Resolution Mode7 can be toggled on/off in the Video Options.
          It is disabled by default since this feature requires a fast CPU.
        - Added 48khz sound sampling rate
        - Tweaked VBlank timing  a bit
        - Tweaked 65816 CPU cycle execution a bit
        - Added Kreed's Super 2xSaI engine.  It's written in C,
          so it requires a really fast cpu to run it.
        - Added picture preview to the save states in the F3 window.
          Newly created save states will contain a small picture in
          them.  Pictures will not appear in old save states, however.

v0.991  - Disabled 2xSaI/Super Eagle when in the GUI
        - Fixed up cheat code search (Got broken in v0.990 during port
          preparation)

v0.990  - Added speed hack for Kirby Super Star (US)
        - SPC700 (Sound cpu emulation) is now enabled by default whether
          sound is enabled or not.  Emulation will now be slower than normal
          if you usually run with sound off, but the compatibility is
          higher.  However, you can disable this through the options
          window in the GUI if speed is of your concern.  Also, a few
          games only run with it disabled so this option may be useful in
          those cases.
        - Decreased cheat code description length by 1 since the last
          letter was causing some corruption to the next cheat code
        - Added an option to raise the pitch level to the pre-v0.989
          pitch levels, mainly for non-Creative brand sound cards.
        - You can now change the sound settings (Enable Sound, Stereo,
          Sound Frequency) with immediate effects without re-starting
          ZSNES.  However, there seems to be some problems with stereo
          switching on SB Live!'s.
        - Configuration is now saved whenever you exit the GUI instead
          of just exiting the program
        - Lots of port preparation done on the source.
        - Memory/Commandline fix on the C version.  A version should
          not be needed anymore (hopefully)
        - The GUI is now using the standard in-game video blitter rather than
          it own.
        - Fixed up SnapShot key in 8bit mode
        - Implemented 4-point gaussian interpolation.  This is the
          interpolation used by the actual snes!  Many thanks goes to
          Neill Corlett for his work on finding this info!
          Of course, this routine takes up an extra cpu load so emulation
          will slow down a bit if your computer isn't fast enough, but
          you can always disable interpolation through the sound options.
        - Fixed up Pitch Modulation method.  Thanks again, Neill!
        - Pitch modulation was modulating from the wrong channel.  Fixed.
        - Tweaked SuperFX timing.
        - Added a move window feature to the F1 menu
        - Expanded filename length in the GUI display for long filenames
          by 3, but had to decrease the directory name by 2.
        - Added support for % codes in long filenames

v0.9891c - Slightly changed SB16 initialization
        - Forgot to remove DSP1 debug code
        - Fixed a pitch modulation bug when Voice 0 modulates Voice 1.
          Thanks to kode54 for this fix!

v0.989c - Fixed some SA-1 sudden slowdowns. This does slow down the overall
          emulation speed in SA-1 games though.
        - All sounds were being played at the wrong pitch (slightly higher
          than normal.  It's now fixed so Zsnes should sound better now.
          Thanks to kode54 for helping out here!

v0.988c - Added some SA-1 speed hacks (Kirby DX/Parodius 3)
        - Implemented SDD-1 MMC.  But none of the SDD-1 games run properly yet
          because of the compression chip.
        - Fixed up some slowdown problems in SA-1 games
        - Fixed up dirty CPUID fix for Cyrix CPUs so that you don't have to
          re-run Zsnes twice every time.

v0.987c - Forgot to re-enable pitch modulation after disabling it for debugging
          purposes.

v0.986c - Re-added Sound Buffering.  I was hoping to re-write it, but
          later found out that it wasn't worth the trouble.
        - Fixed some Triple Buffering bugs, but I can't figure out that
          flicker glitch on NVidia cards
        - Added Simulated Triple Buffering for cards without VESA 3.0 Hardware
          triple buffering.  This method does some lose frames, but should be
          faster than v-sync.  This only works on VESA 2.0 modes.
        - Fixed up directory sorting to always put ./.. at the top.

v0.985c - Added some more speedups to the SA-1
        - SA-1: Fixed a branch problem with the BRL instruction
        - Implemented Save Ram support into netplay.  Thanks to
          The Minder for help testing this!
        - Added a hack to get Mario Paint trainered rom with the trainer
          removed to work with the snes mouse instead of the keyboard/joystick
        - Prevented Joystick Keys/Buttons to be selected as the diagonal
          keys in the GUI
        - Fixed some crashing problems with the Modem Mode
        - Implemented a key combination editor in the GUI
        - Sped up V-Sync
        - Fixed an SA-1 memory map bug!  Fixes DBZ:HD.
        - Added an small speed hack for DBZ:HD
        - Implemented SA-1 Super MMC
        - Finally, after many, many hours of hacking.  Figured out
          what caused the odd noise sounds!  So far, simulated noise
          is implemented since the true nature of how this noise
          is produced is unknown so it will sound somewhat off compared
          to the original sounds.  There is also a slight chance that
          some sounds will become noise incorrectly and vice versa.
        - Fixed up Pitch Modulation
        - Fixed SNES Mouse/Super Scope support when Pl3/4 as Pl1/2 option
          is enabled
        - ADSR/GAIN overhaul (Sound DSP) :
            - Fixed several GAIN bugs
            - Implemented Increase Bentline/Decrease Exp GAIN modes properly
            - Rewrote Decay/Sustain modes in ADSR
            - Fixed a restarting ADSR bug
        - Removed Sound Buffering.  I don't think it's worth losing the
          quality of the sound for a small amount of speed boost.
        - Implemented an option to disable the Noise Simulation for those
          games that aren't working properly because of it
        - Implemented Triple Buffering.  You can enable this through the
          Video Options in the GUI.  Unfortunately, Triple Buffering
          won't work with 2xSaI/Super Eagle engine at the moment since they
          rely on the previous screen for updating nor will it work
          properly with high resolution games in the old gfx engine.
          Thanks to GreenImp for patiently helping through testing!
        - Implemented Full Screen Interpolation.  Only works on MMX CPU's
          at the moment.
        - Implemented Cheat Code Reflector (See Guinotes.txt for details)
        - Any proper VESA 2 error messages now doesn't exit the program
          when in the GUI but instead display the error message in a
          box and allows the user to continue.
        Thanks to Daniel for lending me his copier which helped me hack the
          SNES Sound Noise/ADSR stuff!

v0.963c - Fixed DMA position reader to fix the high sample rate problem
          in SB-Live! cards.  Thanks to ShihTzu for helping us with this!
        - Removed SB16 only message under stereo option in commandline help.
          Shouldn't really be there since v0.600.
        - Low Pass Filter is now disabled by default.  But you can still
          enable it through the GUI.
        - Implemented an option in the GUI to not allow Zsnes to change
          the current start-up game path in the configuration.  You can
          access this in Config->Options.
        - Joystick calibration values have been reset since there seems
          to be some problems with it.  You may have to re-calibrate your
          joystick if it doesn't respond correctly.

v0.962c - Exit text now only displays when text mode is 80x25
        - Used hardware DMA counter to determine which sound block to
          write to rather than assuming it always starts at the first one
          for the sound routines.  This should hopefully fix all those
          nasty sound static problems many people seems to have.
          Many thanks to Crono for the code and for his help!
        - Removed Re-Init Every 30 Second option.  Shouldn't be needed anymore
        - Added the ability to disable the Low Pass Filter
        - Implemented Diagonal Keys
        - Implemented some SA-1 speedups

v0.960c - Modified header reader a bit
        - DSP/SPC700: Modified EndX register usage to fix some compatibility
        - DSP/SPC700: Fixed up timing registers
        - DSP/SPC700: Fixed a sample looping bug causing many sounds to not
          sound correctly
        - SPC700: Fixed a small bug in TCALL.  Not sure if it fixes anything
        - Added small optimisations to the MMX video copy routines
        - Fixed an adsr -> gain switching bug
        - Extended maximum number of cheat codes from 75 to 255
        - Altered .spc format again, this time to suit the ID666 format
        - Worked a bit on SDD-1 emulation.  Don't think we can go
          any further since we can't seem to figure out the compression
          algorithm used in that chip.
        - DSP/SPC700: Added low-pass filter by kode54.  Thanks kode54 for
          the code!  This enhances bass in some games.
        - SA-1: Fixed memory map access problems with several stack
          instructions and d-page instructions
        - SA-1: Minor fix to the timing
        - SA-1: Fixed a load state problem which causes Zsnes to crash
          sometimes
        - SA-1: Fixed a small problem with the cpu communication register
        - SA-1: Added a small speed hack for Kirby 3
        - Added some transparency hacks (Kirby3, FF3)
        - Added an sram fix hack for Donkey Kong Country 2 trainer
          version
        - GUI now displays a message when SAVE CFG is selected
        - Added on-screen messages to the Background/Sound channel toggle keys
        - Added the missing video mode descriptions in the .cfg and
          commandline help

       - Sorry about those new problems in v0.941c.  We traced some of the
         problems to the dos extender zsnes was using (thanks Maxim- for
         some help on this!) so we spent some time rewritng the file system
         so that it would be compatible with other extenders in pure dos.
       - Fixed Save Snapshot + Increment frame enter key affecting the
         game bug

       - You can now quickly modify the currently selected cheat code's
         value by typing a 2 digit hex number in the cheat code enter space
       - Added a hack to Chrono Trigger to prevent the screen from flashing
         before battles
       - Fixed a 16-bit mode 7 windowing distortion/crashing bug
       - Fixed a read memory leak bug in the 16-bit old gfx engine.
         Interesting that this bug plagued ZSNES all this time, but its
         effects didn't show until the recent versions.

v0.941c- Fixed a small newly created timing bug
       - Fixed flicker bug in 320x480x65536 video mode during high
         snes resolution mode

       - Fixed an offset per tile mode bug
       - Optimised SuperFX plot instruction.
       - Implemented a hack to get Winter Gold working.  Thanks to
         Gary Henderson for this fix!
       - Fixed a flag setting bug in the XCE instruction (65816).
       - Fixed another HIRQ bug
       - Seems like a sprite cache bug that was fixed in v0.800 re-appeared
         in v0.900.  Fixed now.
       - Fixed an SA-1 arithmetic calculation result timing bug

       - Added hi-res mode 7 hack to 320x480x256 video mode
       - Implemented 2xSaI engine for ARGB cards.  Thanks to Kreed for
         the updated source!
       - 2xSaI was missing a couple lines at the bottom.  Now fixed
       - 320x480 modes can now be selected in version A in the GUI
       - properly cleared 320x480x256 video mode
       - F3 menu should now be correct during hi-res mode 7 

v0.910c- The bug where enabling auto-cheat load, having an Sram directory,
         and loading a rom without a .cht file which results in Zsnes changing
         the loading directory to the sram directory is fixed.
       - Fixed cheat search engine in version A
       - Tweaked HIRQ timing to fix some flickering in some games
       - Fixed screen shot capture in ARGB cards in 640x480x65536 mode
         with scanlines enabled
       - Implemented adjustable time interval for the sound reinitialization

         Super Eagle engine for now

v0.900c- Fixed another sprite priority bug
       - HBlank is supposed to be noticed during VBlank
       - Fixed an IRQ bug that occured between v0.715 and v0.800
       - Fixed a 65816 DPage usage bug that occured between v0.715 and v0.800
       - Rewrote 65816 flag handling system.
       - Optimised SA-1 emulation
       - Optimised the 65816 main loop.
       - Implemented Surround Sound.  It is defaulted off since it seems
         to create some bad static in some games.  Thanks to Crono for
         info!
       - Wrote Interpolation in MMX.  MMX cpu is required.
       - Implemented MMX auto-detection for MMX Interpolation and MMX Copy.
       - Fixed an 224HDMA line bug, thanks to Gary Henderson!
       - Optimised 320x240x16b and 640x480x16b for ARGB cards.
       - Removed Snow
       - Clock option is now visible to anyone.  You can enable the in-game
         clock through the GUI in Config->Options.
       - Altered method of writing to file in Movie Recording mode, hoping
         that it will fix some problems after recording movies for a long
         period of time.
       - Altered data alignment size in source
       - Fixed a VESA2 divide by 0 bug in Banshee cards by checking the
         scanline length instead of setting it immediately.  Thanks to
         Crono for some help!
       - Altered sound echo volume
       - Added sound interpolation based on Crono's code.
         Thanks to Crono for his help!
       - Added an option to turn off sound interpolation for speed
       - Implemented Pitch Modulation, thanks goes to Gary Henderson for
         clarification info!
       - Implemented an option in the GUI (Config->Options) to allow the
         Fast Forward key to act as a toggle (disabled by default)
       - Fixed a bug that prevented high resolution to sometimes not display
         in a 16bit video mode
       - Fixed a game stalling bug when pressing F3 during games that are
         sensitive to changes in the ENVX DSP register (Bomberman Series)
       - Added a hack for the graphic glitches in Dragon Quest 6
       - Fixed up in-game clock in the new gfx 16bit engine
       - Fixed a nasty bug in the ADSR engine.  It was sometimes using
         an incorrect decay value, causing the sound to stick instead
         of fading out
       - Slightly fixed ADSR by completely skipping the attack stage when
         the attack duration is 0
       - Fixed a GAIN decrease->increase bug
       - Implemented a safe recovery feature for those computers that don't
         support the CPUID instruction (used for MMX detection).  If ZSNES
         crashes at the very start, just re-run it.
       - Fixed a fixed color dual windowing bug in the subscreen which
         caused transparency to sometimes shift unexpectedly when the
         background scrolls
       - Implemented 50% Scanlines (Lance McKay's idea) and 25%
         Scanlines (Similar to Snes9x TV-Mode's scanline intensity)
         in 640x480x65536 video mode.  These modes don't work on videocards
         with an ARGB setting yet.
       - Added MMX Support to 50% and 25% Scanlines modes
       - Implemented back buffer clear in MMX
       - .CHT files now saves to the proper save directory
       - Implemented the 2xSaI graphics engine (MMX Only).  Many thanks
         to Kreed for this wonderful engine and source code!
       - Implemented Kreed's Super Eagle engine.  Note that for both
         2xSaI and Super Eagle, you need an MMX processor, enough RAM for
         the new gfx 16bit engine, and also be in 640x480x65536 video mode.
       - Implemented an option to auto-load a .cht file whenever a game
         is loaded.  You can find this option at the bottom of the Cheat
         Window in the GUI.
       - Optimised Non-MMX Interpolation
       - Fixed a bug that caused save states to not save correctly after
         attempting to load a non-existing .cht file
       - Added a Quick SnapShot Key.  You can set this key in the
         Misc -> GameKeys menu in the GUI.  This key allows you to take
         a snapshot with just a press of a key.
       - Implemented .ZIP support.  Thanks to Jean-loup Gailly, Mark Adler,
         and Gilles Vollant for the ZIP routines!
       - Fixed a bug where pressing PageUp/PageDown in the cheat window
         went over by 3 entries.
       - Implemented longer cheat descriptions.  The cheat window and the
         .cht file format had to change a bit, however, ZSNES automatically
         converts any old formats to the new formats when it detects it.
       - Allowed the IRQ to be executed more than once on the same line
         through HIRQ.  Fixes the flickering problems of Doom/Offroad Baja.
       - NMI now executes at line 225 instead of 224.
       - Saving/Loading the state causing the control to stop or skip has
         been fixed again.
       - .ZIP files can now be run from the commandline
       - Implemented an option for ZSNES to automatically save the save data
         approx. 5 seconds after it detects writes to it.  This will not
         work for SuperFX or SA-1 special chip games, however.  This option
         is disabled by default and can be enabled through the option window.
       - Implemented an option in the sound window to re-initialize the sound
         card after every 25-30 seconds.  Hopefully fixes the problems where
         the sound gets staticy after a certain amount of time.
       - Newest Save Slot will now appear as orange in the Save State
         Select (F3) window
       - Fixed a spc700 <-> 65816 sync bug during movie (.ZMV) playback
       - Implemented an option to enable Old Gfx Engine Mode 2 (Accessible
         through the options window in the GUI).  This mode fixes many
         transparency problems in 16bit modes, but can also create some
         and is also at times slower than the original engine.
       - Implemented 640x480x65536 VESA 1.2 support.  Currently supports
         Full Scanlines and Smallscreen modes.  However, it is strongly
         recommended that you only use VESA 1.2 support if your card cannot
         support VESA 2.0 (w/ linear framebuffer) since VESA 1.2 runs slower.
       - Implemented an option to disable Pitch Modulation
       - Sound card is now not re-initialized whenever a state is saved/loaded
         since some sound cards seems to have problems with it.
       - Implemented Single Windowing in the New Gfx 8bit engine, 8x8
         and 16x16 tile modes only
       - Fixed 64k SRAM support when loaded from the GUI
       - Optimised high resolution new gfx modes in 640x480x256
       - Fixed the graphic glitches in x488 snes vertical resolution modes
         in 640x480x256 new gfx mode
       - Optimised 640x480x256 Eagle Engine
       - Fixed the GUI background display bug in the new gfx engine
       - Fixed .SPC capture in the new gfx engine
       - Added an option to start with the newest save state when the game
         is loaded.  It can be enabled in Config->Options window in the GUI
       - Slightly optimised new gfx 8bit engine
       - Fixed several Mode 7 problems in the New Gfx 8bit engine
       - Changed DSP1 variables to use double instead of floats for a small
         speed increase.  Thanks to Gary Henderson for this tip!
       - Fixed up the Mode 7 slowdown bug when the scale ratio becomes small
         in most graphics modes
       - Optimised some Mode 7 transparency modes
       - Implemented EXTBG mode 7 into the newgfx 8bit engine
       - Fixed the 'FIX' feature in the cheat menu.  Seems like it wasn't
         writing any value to memory when it was clicked.
       - Game Genie codes are now defaulted to the 'FIX'ed mode.  Seems like
         most of the codes needs this.
       - Implemented windowing to Mode 7, New Gfx Engine 8bit
       - Added support for .SPC v0.2 format
       - Added an option in zsnes.cfg to disable configuration saving for
         those who want to store zsnes.exe in a read-only storage area
       - Fixed GameKeys display in the GUI for certain keys (such as the
         snes parallel adapter keys)
       - Implemented hi-res mode 7 (vertical expand only).  Currently only
         works in 640x480x256 newgfx engine (w/ Eagle and Scanlines disabled).
       - Fixed an offset per tile mode bug in the new gfx 8bit engine
       - Implemented dual windowing modes into the new gfx 8bit engine
       - New Gfx 8bit engine is now the default graphics engine in 256 color
         modes.  It still lacks sprite windowing and also has some sprite
         flicker issues, but it's overall more stable, faster, and has
         more features.  You can still switch back to the old gfx engine by
         pressing '8'.
       - Looks like Pitch Modulation was causing more sound problems than
         what it's worth.  It's now disabled by default, but you can reenable
         it through the GUI.
       - Added auto save/load state feature where ZSNES will automatically
         loads back the previous state when you last properly exited ZSNES.
         This feature is disabled by default.
       - Compressed the executable using UPX

v0.800c- Fixed up sound speeds.  Timers were computed incorrectly.
       - Fixed a sprite priority bug
       - Fixed up a bug that prevented the gui to be disabled
       - Fixed up SPC capture
       - Fixed a bug when VIRQ is set on the same scanline as NMI
       - Implemented an automatic .IPS patcher.  Just rename your .IPS
         file to the rom filename with the .IPS extension and ZSNES will
         patch the rom realtime without modifying the rom file's contents.
         Thanks to Neill Corlett for most of the .IPS info!
       - Snapshot capture/skip 2 frames option now returns back to
         the proper menu item
       - Fixed a calibration bug with 6/8button joysticks
       - Fixed up display in 640x480x8 new gfx engine
       - Fixed up hi resolution displays in all 640x480x8b modes
       - Fixed up a bug where Mode 7 becomes corrupt after selecting
         Save CFG from the GUI
       - Fixed a memory map bug in lorom DSP1 games
       - Fixed a potential DSP1 crashing bug where a negative value is
         being square rooted
       - Hopefully fixed the modem bug when using an IRQ that is bigger than 7
       - Fixed up an ADSR bug for games that changes ADSR mid-sample
       - Fixed up echo emulation (possibly slowed down emulation)
       - Fixed up a sprite caching bug
       - Fixed up a DSP1 byte check stall bug
       - Implemented a commandline to disable spc700 speed hacks (-7)
         Might help with some compatibility
       - Implemented SA-1 support (most functions emulated)!  Unfortunately,
         it's still buggy.  Thanks to the snes9x team for providing info!
       - Fixed a bug when selecting drive A/B while a disk is not
         in the drive caused a long check sequence
       - Implemented Keyboard support to most of Option, Sound, and GUI
         Option configurations in the GUI
       - Changed sound init code a bit.  Hopefully improves sound card
         compatibility, but might also ruin it.
       - Implemented off by 1 line fix (-9).  This may help compatibility and
         fix some minor graphic glitches, but may also ruin some too.

v0.715 - Fixed a crashing bug when 16bit back window clipping was using
         an undefined windowing clip buffer
       - Added spc program counter check to the spc stall detection to
         reduce false alarms
       - Tweaked IRQ processing a bit
       - ZSNES.CFG and ZGUICFG.DAT are now fixed so that they will use
         the current directory when the SET CMDLINE detection fails
       - Fixed several mode 7 bugs in the new graphic engines
       - Implemented an option to save the configuration files in the
         MISC menu
       - Added a shadow to the in-game text displays
       - Fixed a bug created in v0.700 where pressing F3 while sound
         is disabled crashes zsnes
       - Fixed up player 4 and player 5 so they now work again
       - Fixed up color a bit in the old graphics 16bit engine
       - Added gamma control to 16bit old graphics engine
       - Fixed a cheat code bug where pressing the down key in the
         browser overflows by 3 rows
       - Fixed up a bug where any memory allocation below 48mbit support
         crashes
       - Added out of memory error when loading a file from the gui
       - Fixed a minor off by 1 pixel windowing bug
       - Fixed up memory requirements in the readme.txt.  It seems like
         compiling with C takes up 3.0 more megs.  It shouldn't though.
         An asm only version will be release later without dsp1/ipx support
         unless the reason is figured out.
       NOTE : It seems like IPX mode randomly loses packets in certain
              configurations so IPX isn't recommended to use yet.

v0.700 - Fixed another offset per tile mode bug
       - Fixed up joystick button update rate
       - Fixed a bug that caused sound buffer dump option to crash
       - Fixed a minor sound initialization bug
       - ZSNES now compiles with C code!
       - Fully rewritten commandline parser routines
       - Partially rewritten SET BLASTER/SET CMDLINE detection
       - Implemented partial DSP1 support.  Seems to have some
         precision problems.  Thanks to the snes9x team for the info!
       - Fixed a mode 7 nonrepeat mode off by 1 tile bug
       - Implemented snapshot/increment by 2 frame feature in the F1 menu
         for those interested in producing animations
       - Added variable sound buffer size to reduce static in higher
         sampling rates
       - Changed method of reading the mouse cursor position in the GUI.
         Hopefully, this fixes those mouse crash problems when zsnes is
         run in pure dos and sometimes win95.
       - Added a commandline to disable palette 0 (back color) modification
         in 256 color modes
       - Implemented Turbo Buttons for buttons A,B,X, and Y.  Use the GUI to
         define those keys
       - Added the ability to toggle Turbo Change speed to 30hz instead
         of 60hz in the Options menu
       - Started C4 chip emulation.  Nothing is playable yet.
       - Fixed up SET CMDLINE detection.  Hopefully, zsnes.cfg and
         zguicfg.dat will now end up in the correct directory.
       - Started Modem Support (direct modem to modem).
         DOS-Compatible modem required!  Thanks to Dark Force for helping
         out on getting a bug that kept USR's and other modems from working!
         Also thanks to The Minder for a lot of help testing!
         Note : Modem mode isn't free of bugs
       - Added in-game chat key to the GUI keys for modem/net support.
         Currently defaulted to 't'
       - Forgot to add EMMS after any MMX routines that seems to cause
         any FPU instructions to crash
       - Fixed an interrupt re-enable bug in the Gamepad Pro code which
         seems to have eliminated the locking bugs when it's not set on
         GrIP mode
       - Implemented keys to adjust Frame Rate up or down during
         gameplay.  You can define them through the GUI under Gamekeys
       - Implemented keys to slide the volume level up or down during
         gameplay
       - Fixed a small HDMA screw up bug when using Save/Load states
         which caused the screen to flicker once in many games
       - Finally fix up 48mbit mapper support!  Many thanks to Dark Force,
         Mike Gilroy, and Frank Hughes for a lot of help on this!
       - Several fixes to register 4211h
       - Rewrote IRQ timing handler (not perfect, but better)
       - Implemented Fossil Driver support to the modem support.
       - Fixed an IRQ reenable bug
       - Increased default cycles a bit
       - Fixed some major mode 7 rotation bugs
       - Added support for uninterleaved 48mbit roms
       - Added a FIX option to the cheat code to correct incorrectly
         converted codes
       - Implemented Mode 7 horizontal flip
       - Implemented primitive IPX support.  It is very primitive at
         the moment and may not work since it isn't really tested much.
       - Optimised some 65816 direct page addressing modes
       NOTE : .ZMV (Movie) files recorded under v0.635 has good potential
       on becoming obsolete in this version because of the timing changes
       NOTE : IPX support and Modem support may be buggy since it hasn't
       been tested on multiple types of connections yet.

v0.635 - Sidewinder fix options are now swapped since the majority seems
         to work better with the other sidewinder routine.
       - Implemented EXTBG mode7 in 256 color old graphics engine.
       - Fixed a DSP Sound bug where some sound effects weren't played in
         certain games
       - Tweaked joystick routines again
       - Fixed up a bug where sometimes loading a game after playing
         another game screws up emulation
       - Optimised 640x480x8, 512x384x8, and 512x384x16 video modes
       - Implemented EXTBG mode7 in 65536 color old graphics engine.
       - Fixed an offset per tile mode range clipping bug
       - Fixed up offset per tile mode in new gfx 8bit engine
       - Fixed a bug which caused a crash when a state is loaded while
         playing/recording a movie file
       - Optimised new gfx 16bit non-transparency mode
       - Implemented SPC700 stall detection/recovery attempt
       - Fixed up a new header detection bug in v0.625
       - Modified memory allocation routines.  Hope this fixes those
         random crash problems that some people seem to have
       - Fixed a sound bug where the song leaks after it ends,
         sometimes producing an unwanted beep
       - Optimised new gfx 16bit transparency modes
       - Multiple DSP sound bug fixes
       - Implemented transparencies in high res 16x8 tiles
       - Implemented a command line to disable the sound DSP (-dd).  Use
         -s and -dd if you want spc700 emulation to be enabled without sound
         to improve compatibility
       - Fixed a bug where joystick support makes the emulation slow
       - Had to remove some memory allocated variables and convert them
         to arrays since they were causing random crashes on specific
         computers.
       - Fixed up pressing save state/load state in game so that it doesn't
         clear any key presses

v0.625 - Fixed up a major speed drop bug by just adding some empty space.
         Most likely a cache/alignment problem.
       - Used an older version of wdosx because the new version sometimes
         crashes during compiling
       - Executable is now uncompressed.  It's 3 megs, but it provides a
         much faster start up time.
       - Seems like EPACK can only support a maximum of 6 commandlines.
         Fixed after executable is decompressed
       - Fixed a bug where buttons 7 and 8 of 8 button joystick support
         sticks once pressed
       - Swapped button 5/6 and 7/8 in the default joystick configuration
         for 8 button joysticks
       - It seems like 16bit HDMA < 5 was causing problems with some
         sound cards.  It now reroutes back to 8bit DMA like how v0.400
         did it.
       - Implemented a new offset per tile mode engine into the old
         graphics engine (mostly transferred from 8bit newgfx engine)
       - Implemented Horizontal offset per tile mode in both 8bit and
         16 bit old graphics engine (Mode2/8x8 only)
       - Implemented Horizontal offset per tile mode in 8bit new graphics
         engine (Mode2/8x8 only)
       - Tweaked sidewinder routines.  Hopefully, this will help those who
         have troubles using sidewinder support
       - For those with sidewinder pads who has troubles with the tweaked
         routines, a 'Sidewinder Fix' option in the GUI is added in the
         Config/Options menu
       - Commandline -i now uninterleaves an incorrectly interleaved rom
       - Tweaked GamePad Pro routines.  Not exactly sure if this will help
         those with 2 GPP joysticks though
       - Fixed up sticky buttons in the GUI cheat menu when no cheat
         codes are present
       - Fixed a bug where using -1 and -2 in the commandlines didn't
         activate the joystick movement/buttons
       - Fixed an offset per tile mode wrapping bug
       - ZSNES will now not crash when zsnes.cfg and zguicfg.dat are
         write protected files
       - Fixed up the GUI when 239 y resolution is used in the game
       - Optimised some minor mode 7 routines
       - SNES Header display in the GUI now displays the filename for
         blank headers.  This will fail for headers with garbled header
         names

         at the end of the address
       - Removed the blank line from the .PCX and .BMP snapshots
       - Implemented Joystick Calibration for non digital joysticks
       - Fixed a bug where parallel port LPT2 player 2 wasn't selectable
         in v0.605
       - Stabilized the joystick code a bit
       - Fixed up a cheat code bug where using a PAR code that accesses
         RAM doesn't freeze when the .cht file is loaded
       - Added a small delay to play a note when a key on is issued from
         the sound DSP.  Not sure if this fixes anything though
       - Fixed some sound compatibility problems when RESET is used
       - Implemented Movie Record/Playback support.  Read GUINotes.txt
         for details.
       - Added a small detection for long filenames and prevented users from
         selecting it when it isn't detected
       - Fixed a bug where max frame skip didn't save
       - Fix a timing bug where running a game off the gui ran 1 less
         line in the 65816 than running off the commandline
       - Implemented FPS at start option in the Config/Options menu
       - Fixed a bug in the newgfx16bit engine where 8bpp tiles displayed
         incorrectly
       - Reduced the filesize by 1200k through many changes in the code
         (filesize is now 2.0 megs)
       - Fixed some VIRQ bugs that caused certain games to crash
       - Added DMA area execution for IRET
       - Added a 'Bugs Section' in the readme.txt
       - Show all extensions is now disabled when snes header view is
         selected in the GUI
       - Implemented partial Direct Color mode in Mode 7 (no transparencies
         yet, only works in 16bit old gfx engine)
       - Improved header detection a bit
       - Fixed up a sprite bug in games which changes the address in
         the middle of the screen

v0.605 - Fixed up a FPS display bug when switching between auto frame rate
         and manual frame rate in the GUI
       - Cheat Codes can now be toggled ON/OFF by double clicking on them
       - Tab key now switches from the Cheat Code enter box to the
         Description box
       - Fixed a Save State/Load State bug in the menu where it saved
         in the load directory instead of the save directory
       - Implemented 8button joystick support (Not tested)
       - Implemented an option in the .cfg file to enable reversed
         stereo sound (ReverseStereo)
       - Implemented an option in the .cfg file to share Player 1 and
         Player 2 controls with Player 3 and Player 4's controls.  This
         option allows you to use 2 devices (Joystick and Keyboard) for
         both player 1 and player 2, but this also disables MultiTap
         support. (Pl34to12Share)
       - Added Reverse Stereo to the GUI under config/sound
       - Added Player 3, Player 4 to use as Player 1, Player 2 in the
         GUI under config/options
       - Compiled under a new version of wdosx.  Hope this doesn't cause
         any problems

v0.601 - Fixed up a sound card deinit bug that sometimes caused ZSNES to
         crash in certain sound cards
       - Disabled Autoinit mode when a low sampling rate is used in 8bit
         sound.  Probabily was also causing problems in some cards

       Note : The offset per tile mode in the 16bit oldgfx engine seems
         to randomly crash sometimes for an unknown reason.  If 16bit mode
         crashes for you and 8bit doesn't, press the '0' key in 16bit mode
         to disable that mode.

v0.600 *** ADDED A NEW MEMBER TO THE ZSNES TEAM! ***
       Welcome Pharos to the team, his role is currently a coding assitant.
       So far, he helped us objectize the zsnes source code which greatly
       helped in the compile time, provided assembly help, and helped us
       prepare on linking C code to zsnes (not completely there yet).

       Note : It is strongly recommended to not use the 16-bit new
              graphics engine yet because of bugs and speed concerns.  It
              is enabled only in 320x240x65536 for those who are interested.

       - Added partial 65816 execution in the DMA registers (doesn't seem to
         fix mucht due to some other problem) Thanks to Alucard for this
         info!  This also slowed down emulation a bit.
       - Implemented sprite priority correction into the new graphics engine
       - Implemented mosaic into the new graphics engine
       - Implemented true 512 horizontal resolution into new graphics
         engine (both 16x8 and 16x16 tile modes)
       - Implemented interlaced 448 vertical resolution into new graphics
         engine
       - Implemented offset per tile mode into the new graphics engine
         (Mode 2/Vertical only).  More accurate compared to the old
         graphics engine. (seems to be a bug where the game gets very
         slow sometimes though)
       - Started 16-bit new graphics engine
       - Implemented sprite priority correction in 16bit new gfx engine
       - Implemented palette raster effects in 16bit new gfx engine
       - Fixed a minor bg enable/disable bug in the new gfx engine
       - Multiple SPC700 bug fixes.  More games run now!
       - Implemented SPCPlay sound engine into zsnes :
           - Echo & FIR Filter Support (Slowed down emulation, but
             gives better sound) Thanks to feenix65 for info on FIR Filter!
           - Volume fixes
           - Rewrote ADSR/GAIN engine
           - Added Adjustable Volume through the commandline and zsnes.cfg
           - 16000 and 32000 extra sampling rates
           - Many other bug fixes
       - Fixed a minor HDMA bug
       - Fixed an old style joystick read bug that prevented the joypad
         from functioning in certain games
       - Several optimisations on Echo & FIR Filter
       - Several Sound DSP Fixes
       - Temporarily fixed a V-latch bug in some games that don't update the
         display at every frame
       - Add/Removed some game hacks for compatibility
       - Modified Song Start Search in .spc capture.  Should be much better now.
       - Fixed a sprite window clipping bug where it was used when it's not
         supposed to be.
       - Modified memory allocation technique in zsnes.  This should now
         eliminate some random crash errors.  Thanks to Y0SHi for this
         info!
       - -c now does full screen instead of small screen in 640x480 modes.
         For small screen, use -cc
       - Fixed a back area 1/2 addition bug which caused the background
         to be sometimes darker than usual
       - Fixed a mode 7 transparency bug
       - Added 8-bit stereo sound and 8-bit sound high speed mode support
         (high speed mode support is just the implementation of 8bit 44100khz
          or 22050khz stereo)  Thanks to Crono for a lot of help on this!
       - Fixed up sound blaster deinit code
         Thanks again to Crono!
       - Wrote an entirely new GUI :
           - Mouse driven GUI/Menu Based
           - Full Keyboard Support in all the Quick (Arrow Menu), Load,
             and Cheat menu items
           - Ability to display load names under 8.3 filename format, snes
             header name, and win95 long filenames
           - Support for Save State, Load State, and Select State through
             menu items
           - Quick Load Menu (Arrow menu) which allows you to quickly load
             the last 10 games loaded
           - Ability to Freeze or Clear the Quick Load Menu
           - An Options menu which allows you to configure settings such
             as video mode, sound settings, frame skip, etc.
           - Added the ability to customize the game keys such as
             the save state key, misc toggles, etc.
           - Ability to use those keys as joystick buttons
           - Customizeable background palette displacement
           - Several minor GUI customization features
           - Ability to quickly exit/enter the GUI with the right
             mouse button (Disabled by default)
           - Ability to Enter Game Genie, Pro Action Replay, or Game
             Finger Cheat Codes
           - Ability to browse the cheat codes and Toggle or Remove
             the codes
           - Ability to Save/Load Cheat Codes (saves them as .CHT files
             in the same directory as the .SRM/.ZST files)
           - Ability to Select Input Devices for each joypad
           - Ability to Define Keys/Button configuration for each joypad
           - Joypad can now move in the GUI (disabled by default)
           - Added some future reserve menus (Netplay, Cheat Search Engine)
             But they are NOT implemented in zsnes yet.
       - Fixed a bug when clearing the screen in 640x480x65536
       - Implemented full add, half add, full subtract, and
         half subtract into the new 16bit graphics engine
         Not sure why, but some transparency modes are actually slower
         than the old engine.  Most likely flushing the cache a lot
         somewhere.
       - Implemented background transparencies into new 16bit graphics engine
         (implemented incorrectly at the moment.  Some transparency modes
         also is slower than the old graphics engine, but that will change
         in the future)
       - Implemented fixed color transparencies (very incorrect because of
         lack of windowing)
       - Fixed a minor bug in the fast forward routines
       - Rewrote most of the 65816 speed hack.  It should now be a lot
         more friendly with games (reduced graphic glitches/increased
         compatibility).
       - Fixed a bug in Mode7 with Windowing and Transparency enabled
       - Allowed 16bit HDMA sound blaster values less than 5 to be used.
         Not exactly sure if this works though.
       - Implemented Mouse Disable Command Line (-j)
       - Rewrote Input Device Routines (Keyboard, Joystick, SNES Mouse,
         and Super Scope Handlers)
       - Added GamePad Pro Support (Don't know if it works on a standard
         GrIP system though).  Thanks to Marius Fodor for the code!
       - Added Snes Parallel Port Support for both LPT1 and LPT2.
         Thanks to Karl for the code!
       - Added MultiTap (Multiplayer 5) Support!  (Only up to 4 players at
         the moment though)
       - Joystick Port 209h support
       - Fixed an overflow caching bug in the new gfx engine where a few games
         run very slow
       - Added some C -> ASM converted DSP1 functions.  Some functions
         were unable to convert properly so no DSP1 games are playable until
         the actual C code is in
       - Executable is now compressed using epack
       - Implemented sprite transparency into the 16-bit new graphics engine
       - Implemented mode7 transparency into the 16-bit new graphics engine
       - Higher memory requirements (Sorry, but this is unavoidable as long
         as ZSNES keeps expanding)
       - Implemented Echo Disable in the zsnes.cfg for those who want some
         extra speed in return for lost sound quality
       - A bunch of other fixes that we forgot to list

v0.400 - Fixed a dual windowing bug in mode 7 in 65536 color mode
       - Re-added FPU Copy due to a demand
       - Implemented MMX Copy.  Use -om to enable.  Thanks to Angels Holocaust
         for this info!
       - Fixed a bug when writing to .bmp files
       - Added (buggy) SuperFX support (9.5MB memory required)
         Special thanks to the snes9x team for all the info and help!
       - Fixed up sprite windowing.  Should hopefully be correct now
       - Added a commandline to show all file extensions through the GUI
         Use -sa to enable
       - Added Noise to the Sound DSP
       - Added a Fast Forward key.  Use the Tilde Key (~) located at the
         top-left of your keyboard.
       - Added Sprite Priority Correction
       - Fixed a tile caching bug that caused some tile corruption
       - Fixed a 65816 bug in XCE on the x flag.  Thanks to ]SiMKiN[ for this!
       - Implemented Interleaved format and a simple auto detection.  In case
         autodetect fails, use -i.  Thanks to feenix65 for this info!
       - Improved header detection.  Should now work better with demos
         and games with weird filesizes
       - Added a new graphics engine in 256 color mode.  It should be much
         faster in areas that don't use mode 7, but lacks a lot of features
         such as windowing, mosaic, and sprite priorities so it is disabled
         by default.  It can be enabled by pressing 8 during gameplay.
         (~40-100% faster)
       - Optimised Mode 7 in 256 color mode
       - Implemented dual windowing to color window clipping
       - Fixed several color window clipping bugs
       - Added full resolution screenshot capture in 640x480x65536 mode
         To activate while in that mode, hold backspace and press F1
       - Fixed several transparency bugs
       - Added NewGfx to zsnes.cfg which determines if the new graphics
         engine is enabled at start
       - Added CopyMethod to zsnes.cfg which can default the copy method
         as either fpu copy or mmx copy
       - Allowed systems with 5.5MB of RAM free to load 2mbit roms
       - Fixed sidewinder support when sound is set at a high sampling
         rate.  Thanks to Marius Fodor for the source!

v0.393 - Whoops!  Forgot to remove the debug variables in v0.391
       - Fixed another sprite clipping bug
       - Fixed clipping in Mode7 16-bit mode
       - Removed FPU Copy since it didn't seem to speed up emulation
       - Added .USA and .JAP rom extension into the GUI
       - Added Save SPC Data which saves the contents of the SPC700/DSP
         of the beginning of the next song (Future Reserved)
       - Add Sound Buffer Dump which dumps the decompressed sound buffer
         as raw pcm.  This can become quite inaccurate due to the way how
         zsnes stores its decompressed sounds.
       - Added MenuItem Sound Buffer Dump into the F1 Menu
       - Added MenuItem Save SPC Data into the F1 Menu
       - Added a key to disable offset mode.  Press 0 key to
         activate/deactivate
       - Added small screen support in 640x480VESA2 modes.  This mode
         should be much faster for those who use 640x480.
         Use the -c commandline to enable this when in 640x480.
       - Added an option for centered small screen.  Use the -cc commandline.
       - Fixed up 320x240x65536 support for ARGB cards again.  It now
         should be working. (No, seriously!)
       - Removed some static from the sound.

v0.391 - Fixed a bug in DMA from v0.390
       - Fixed some sprite windowing clipping bugs
       - Fixed an OAM overflow bug.  Thanks to DJRob for some help on this!
       - Fixed a save state bug where running a game off the commandline
         and having a save directory specified prevented more than 1 save
         state
       - Fixed a transparency bug from v0.390

v0.390 - Fixed a bug which caused 320x240x65536 to display incorrectly
         on video cards with an 16-bit ARGB setting
       - Fixed a minor screen add/sub bug
       - Fixed a minor sprite priority bug

       - Implemented 64k sram files
       - Implemented Sprite VRAM address changing in the middle of the screen.
         Should fix some games such as Lufia 2
       - Added some hacks to get some games working better
       - DSP : Fixed a divide by 0 bug when key on is set without any sound
         variables initialized
       - Increased default cycles executed in FastROM.
       - Added ZSNES.FAQ .  Read this if you have troubles!
       - Added a key to disable/enable Windowing.  Press 9 to
         activate this.
       - Implemented EAGLE algorithm in 640x480x256 video mode.  Use
         -y to enable.  Thanks to A CoolMan for the algorithm!
         Later on, we'll implement his code which has MMX acceleration!
       - Implemented FPU copy.  Use -o to enable.  Used only when copying
         buffer to video in 320x240 vesa2 modes.
       - Re-wrote Windowing routines for speed and expandability
       - Added Dual Windowing on BGs in all logic modes
       - Added Dual Windowing on Sprites
       - Added some minor stuff to the header displayer
       - Added partial offset per tile mode. (Mode 2/Vertical/8x8)
         Thanks to the feenix65 for some help on this!
         Implementation still a bit buggy.
       - Sorry, but memory requirements had to increase by a bit.
       - Fixed a tile graphics wrapping bug
       - Clean up and optimised 16-bit graphics code
       - Fixed up a display bug when switching from 239 to 224 y resolution

       - Minor optimisations to the 65816
       - Improved color intensity in the back area
       - Fixed a sram directory bug where the save state didn't save in the save
         directory when the game is specified from the command line
       - Fixed a keyboard bug when left-shift is selected as a key.
         Thanks to Pharos for help on this!
       - Some DMA speedups
       - Some optimisations to OAM/VRAM write
       - Sorry, but SuperFX emulation is disabled for this public version.

v0.305 - Fixed a snes ppu multiplication bug.  Thanks to Lord Esnes!
       - Hopefully fixed 6-button joystick support.
       - Fixed a little memory overflow bug which caused some games to not
         work
       - Forgot to clear NMI wait substitute variables when another game
         is loaded from the GUI
       - Changed sound processing engine back to v0.297.  If for any reason
         you want to go back to v0.300 sound engine, use -x as a command line
       - Added Cursor Mode Button to the Super Scope.  Never thought it was
         necessary until recently.  Use the =/+ key.

v0.300b - Fixed a bug that causes sidewinder support to crash.
