- Fixed up a display problem in the F1 menu in 256 color mode
- Fixed an echo delay bug
- Hopefully fixed the random beep encounter bug that occurs in some games with sound enabled
- Several sound volume fixes
- 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
- Added Increment Frame Only option to the F1 menu
- Made some minor changes to the Sound Blaster routines

- 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!

- 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
