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

occurs in some games with sound enabled
- Several sound volume fixes
- Sorry about those new problems in v0.941c. We traced some of the

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

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

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.

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

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

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

- 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.

16 bit old graphics engine (Mode2/8x8 only)
- Implemented Horizontal offset per tile mode in 8bit new graphics
engine (Mode2/8x8 only)

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

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)

- 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

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!

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

- 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)

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

- 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
