ZSNES by zsKnight, _Demo_, and Pharos ZSNES is a Super Nintendo Entertainment System emulator written mostly in assembler. It runs commercial games and even with sound. However, it still lacks compatibility and the sound still has bugs. We would really like to thank the snes9x team for all their help and also for an excellent snes emulator. We also wish them the very best of luck! --------------------------------------------------------------------------- Table of Contents --------------------------------------------------------------------------- 1.)

Disclaimer --------------------------------------------------------------------------- zsKnight, _Demo_, and Phaors are not responsible for any damages caused by the use of this software. This software also must not be distributed with ROMs. --------------------------------------------------------------------------- 3.) System Requirements --------------------------------------------------------------------------- Absolute Minimum System that ZSNES can run on (but strongly not recommended) : - 386 processor (486 processor required for new graphics engine) - 11.5MB of RAM (You need at least 9.5MB free) - VGA card Somewhat Recommended System : - 486/100 processor - Min 11.5MB of RAM (min 9.5MB free, only can run 2MB rom images) - VGA card - Sound Blaster or 100% compatible Strongly Recommended System : - Pentium processor (P100 or higher) - 16MB of RAM (min 14.0MB free) - SVGA card - Sound Blaster 16 or 100% compatible Recommended System for 65536 (16-bit) color mode : - Fast Pentium processor (P166 or higher) - 16MB of RAM (min 13.0MB free) - SVGA card which supports 320x240x65536 or 640x480x65536 colors - Sound Blaster 16 or 100% compatible Recommended System for SFX support : - Fast Pentium processor (P200 - P2-300 (depending on the game)) - 16MB of RAM (min 13.0MB free) - VGA card - Sound Blaster 16 or 100% compatible Recommended System for SA-1 support : (Mario RPG) - Fast Pentium processor (P200 or higher) - 16MB of RAM (min 13.0MB free) - VGA card - Sound Blaster 16 or 100% compatible - You need 13.0MB of RAM to run 48mbit(6megabytes) roms. - You need 14.0MB of RAM to use the new graphics 16bit engine. - An FPU is required for DSP1 emulation For SuperFX and SA-1 emulation, 13.0 megabytes of free memory is required to run. --------------------------------------------------------------------------- 4.) Things you should know about ZSNES --------------------------------------------------------------------------- - You can use both keyboard and joystick for player 1 or 2 with some configuration adjustments. Refer to zsnes.faq for details - If your sidewinder support doesn't work, a quick way of getting it to work is to fully disable the windows driver from the control panel - For modem mode, if you don't have a 16550A UART compatible modem (It will tell you when the modem initializes), chances are that both sides will go out of sync. - IPX support seems to randomly lose packets in certain network configurations which causes both sides to go out of sync - Several special chip emulation (SA-1) have unknown bugs to them - Transparency effects are only available in 65536 color mode - Using 320x240 resolution modes are faster than 640x480 modes. Use 640x480 modes only if you can't run 320x240 modes or if you want the added features of 640x480 modes - New Graphics 16bit only works on 320x240x65536 mode at the moment - New Graphics 16bit engine is missing many effects so many games won't display the graphics correctly when using this mode. - To view 512 resolutions properly, use 640x480 mode. Only a few games uses 512 resolution. One way to find out is to see if a game has that feature is to look for text that looks squished. - True 512 resolution isn't implemented in 640x480x65536 interpolation, non-scanline mode. - Scrolling in 512 resolution under 640x480 may appear choppy since it alternates between the left and right pixels at each frame. - In 640x480 resolution, the image is scaled so it will look like 320x240 resolution. Only use 640x480 resolution if you want to use scanlines, interpolation, or if 320x240 doesn't work. - SuperFX can be slow because it is an extra 10/20mhz cpu that has to be emulated as well as the snes emulation - Screen Snapshot and FPS counter are available through a menu by pressing F1 during emulation - Screen Snapshot currently saves as Image.PCX (256 colors) and Image.BMP (65536 colors). This may change in the future. - FPS counter currently only works when auto frame rate is on. One for non auto frame rate will probabily be implemented in the future when we have time. - To use the cheat function, be sure to have the ROM which you want to patch loaded already. - If the cheat codes do not work, chances are that you are using a different version of the rom that was originally used to create them or the codes are converted incorrectly from other code formats. - Certain video cards/monitors cannot support ModeQ (default resolution) If your video card/monitor doesn't support it, run ZSNES with -v 0. If -v 0 doesn't work, use -v 2 (vesa 2 required) - 16 bit mode in ZSNES requires a Scitech Display Doctor (v5.3+) to provide high color, low resolution modes. You can obtain this software at www.scitechsoft.com. If your video card already supports lo-res, hi-color, then don't worry about getting this driver. - Full Screen addition/subtraction in 65536 mode uses a 13-bit color palette (8192 colors) instead of a 15-bit color palette (32768 colors) used on a real snes when using full add/sub. - There are still many bugs left in ZSNES so don't expect it to run all your favorite games. - VSync won't run well unless you specify a frame skip (eg. -f 0) But this feature is highly recommended to be used on very fast machines (eg. Pentium IIs) - The sound buffering is a little buggy at the moment. It is disabled by default and can only be enabled through a command line (-Q). - SNES Mouse support is still missing some features such as speed settings - Pressing the Fast Forward key is equivalent to running ZSNES using -f 9 - If ZSNES doesn't work for you, then don't use it. Use SNES9X, NLKE, SNEESE, or SNEMUL instead! In fact, even if you use ZSNES, use those emulators too! --------------------------------------------------------------------------- 5.)

Future Progress --------------------------------------------------------------------------- This section is removed --------------------------------------------------------------------------- 7.) ZSNES Default Keys --------------------------------------------------------------------------- Here are the default keys while running the emulator. They can be changed through the GUI except for F1 and ESC : Disable Backgrounds 1,2,3,4 = 1,2,3,4 Disable Sprites = 5 Panic Key (enable all) = 6 Enable SNES Mouse/SuperScope = 7 Enable New Graphics Engine = 8 Disable Windowing = 9 Disable OffsetMode = 0 Fast Forward Key = ~ PopUp Extra Menu = F1 Save State = F2 Switch State = F3 Load State = F4 Disable Sound Channel = F5 - F12 Quit = ESC Here are the default keys for the game play (unless modified through the GUI): Player 1 : Up,Down,Left,Right : Cursor Keys on Numerical Pad (You can also use the non-numerical pad, but numerical pad is strongly recommended) A,B,X,Y : Home, End, Insert, Delete L,R : Page Up, Page Down Start, Select : Enter, RShift Player 2 : (You need to enable Player 2) Up,Down,Left,Right : K, M, N, < A,B,X,Y : D, X, S, Z L,R : F, C Start, Select : Ctrl, Alt To run the emulator, just type ZSNES <romname.smc/.sfc/.fig/.1> To run it with sound, type ZSNES -s <romname.smc/.sfc/.fig/.1> To run it in 16-bit mode (VESA2 w/ video card that supports 320x240x65536 required), type ZSNES -v 3 <romname.smc/.sfc/.fig/.1> or with sound, type ZSNES -v 3 -s <romname.smc/.sfc/.fig/.1> --------------------------------------------------------------------------- 8.) Extra Pop-Up Menu (F1 Menu) --------------------------------------------------------------------------- Save Snapshot - Saves a snapshot as either .PCX (8-bit color) or .BMP (16-bit color) Show/Hide FPS - Shows or hides the frame per second display which appears on the bottom-left corner of the screen. This can only be enabled in auto-frame rate mode. Save SPC Data - Selecting this will search for the beginning of the next song and save the data into a .spc file which saves it similarly as a .srm file. To capture a song, it is best recommended to initiate this feature approx 2 seconds before the next song starts. This does have potential to fail though so don't expect it to work all the time. Also, this feature doesn't work in the new gfx engine. Sound Buffer Dump - This dumps the sound buffer in zsnes and also filters out any unoccupied space. The sound buffer contains decompressed samples which are written to when zsnes plays/decodes a sample from sound memory. Because of the way zsnes buffers the sound data, this can produce inaccurate results. Snapshot/Increment Frame - Same as snapshot, but it returns to the F1 menu after a couple frames. Useful for making animations. --------------------------------------------------------------------------- 9.) Configuration File (ZSNES.CFG) --------------------------------------------------------------------------- Almost everything in zsnes.cfg should now be editable through the gui --------------------------------------------------------------------------- 10.) Cheat Codes --------------------------------------------------------------------------- Currently, ZSNES supports Game Genie, Pro Action Replay and GoldFinger codes Here are the steps to get the codes working : 1.) Load the ROM which you want to patch 2.) Exit to the GUI, enter the code of your choice in the cheat menu 3.) After that, you may have to RESET the game to get the cheat code to work. Sometimes, it is not necessary. You also may have to click on the FIX button. NOTE : Some cheat codes are meant to be for different versions of the game. If a cheat code doesn't work and there is one for both Game Genie and Pro Action Replay, try them both. --------------------------------------------------------------------------- 11.) Extra Features (SNES Mouse/Super Scope/SuperFX/DSP1/MultiTap) --------------------------------------------------------------------------- To Enable SNES Mouse, Press 7 once for 1st player and twice for 2nd player To Enable SNES Super Scope, Press 7 three times To disable either one, either press 6 or press 7 until you see a disable message onscreen. Here are the controls for the Super Scope : Fire = Left Mouse button Cursor Mode Button = Right Mouse button Pause = Backspace Key on keyboard Enable/Disable Autofire = =/+ key on keyboard, should be located to the left of the backspace key DSP1 is enabled automatically. Currently, it runs mario kart and some other games, but it does not run pilotwings due to a lack of dsp1 functions that are implemented. Zsnes auto-detects the SFX emulation from the header and enables it when found. Also, take note that the SFX is an additional 10Mhz(Ver1) or 20Mhz(Ver2) chip which also has to be emulated with the snes and will most likely produce a very noticeable slow down in emulation. Sometimes, the Multitap isn't compatible with some games. If that happens, disable Multitap by setting Player3 and 4's input device to 'None' in the GUI IPS patcher : Rename your .IPS file to the rom filename with the .IPS extension (eg. If your rom is SD3.SMC and your rom is SD3V05.IPS, rename SD3V05.IPS to SD3.IPS) and ZSNES will patch the rom realtime without modifying the rom file's contents. --------------------------------------------------------------------------- 12.) Bugs Section --------------------------------------------------------------------------- - Several transparency effects are incorrect in zsnes due to some priority problems that are not easy to implement. If you encounter a problem in transparencies (and make sure you're in 16bpp mode), try changing to the new graphics 16bit engine since it handles the transparencies differently or you can also try switching to the Old Gfx Mode 2 engine which is selectable from the Options window in the GUI. - 65816 lacks correct timing. Although ZSNES bases the timing on a variable cycle/instruction, it does not deduct correct values such as 16bit instructions should deduct 1 more cycle than 8bit instructions. 100% cycles of zsnes isn't 100% cycles of a snes because of that. This means that a lot of games either won't run or will produce horrible displays. Sometimes adjusting the % of execution can fix those problems. - Games sometimes tend to not display things properly because of graphic features that aren't implemented yet - The Sound DSP chip still has its bugs - Several Sound Effects such as Wind , Soft Noises, etc. play incorrectly and tend to sound like beeps or loud howling noises. We are currently unsure on what causes this and it will be addressed once we find out. --------------------------------------------------------------------------- 13.) Contact Information --------------------------------------------------------------------------- The ZSNES homepage is located at : http://www.zsnes.com If you have any questions about zsnes and you have read ZSNES.FAQ, README.TXT, and GUINOTES.TXT to make sure the answer isn't there. And your question is NOT a ROM Request or asking about a newer version, you can post your question at the zsnes www board located at : http://www.zsnes.com/board/ Remember : This board should be mainly used for zsnes related questions. ROM requests (or asking for games, a link to a rom site, or where to find them) are forbidden!!! Be sure to also read the RULES! The link to the rules is located at the top of the page. If you wish to contact the authors, you may contact them through : (Remember - No ROM requests please! and don't send any files without permission!) zsknight@zsnes.com _demo_@zsnes.com pharos@zsnes.com Try not to send a copy of your e-mail to all of us since that will just waste our time. Also, don't expect to get a reply since we are often busy. --------------------------------------------------------------------------- 14.) The Debugger --------------------------------------------------------------------------- Note : The debugger is disabled when you don't enter zsnes with a -d Here are the keys: 1 : Enable/Disable spc700 display 2 : Enable/Disable 65816 display T : Trace (in 65816 opcodes) B : 65816 break point S : SPC break point C : Clear Counter M : 65816 modify A : SPC modify D : Debug Dump (SPC/DSPRam Dump Only) W : Break at signal (Used only by the programmers) F1 : Exit debugger and return to Game F2 : Save State F4 : Load State ESC : Exit entire program --------------------------------------------------------------------------- 15.) Error Codes --------------------------------------------------------------------------- Unable to Initialize VESA2 : VBE not detected - ZSNES Failed to detect any VBE interrupts (Your video card doesn't support VESA) VESA not detected - ZSNES Failed to detect any VESA extensions (Your video card doesn't support VESA) VESA 2.0 or greater required - Your video card supports VESA, but it has an old version of VESA. You may want to use SDD (www.scitechsoft.com) to upgrade your vesa driver unless you have an S3 video card which you can get a vesa 2 driver from www.s3.com. VESA2 mode does not work on your video card/driver - Meaning that the resolution you chose does not exist in the supported resolutions of your video card. Chose a different resolution or upgrade with SDD which can sometimes help increase the number of resolutions supported Unable to initialize video mode - A VESA 2.0 driver is found, but the video mode failed to start. Possibly an error on the video card setting or a defective hardware Linear Frame Buffer not Detected - Meaning that your video card does not support linear frame buffering which is required for ZSNES' vesa 2 routines Modem Mode : Modem Response Timeout - If this appears, then either your modem isn't configured properly (Even though your COM port is set up properly, chances are your IRQ isn't), some other application is using the modem (such as an internet connection), you don't have a DOS compatible modem, or your baud rate isn't set up to the speed of your modem (this isn't required for all modems though, but for some, it's required) Cannot Init Driver - This means that you have the FOSSIL DRIVER option checked, but no fossil drivers are loaded Carrier Detected (When you're not connected) - This Probabily means that you have set your COM Port/IRQ incorrectly. This also might mean that you don't have a dos compatible modem or the modem is being used somewhere else such as an internet account. After Connection (Modem and IPX Mode) : Incompatible Version - This means that both sides are using different versions of zsnes. Both sides must use the same version in order for remote play to proceed. Invalid Sound Setting - This means that one side has sound disabled while the other has it enabled. Both sides have to either have sound disabled or sound enabled because the game timings of both settings are different. --------------------------------------------------------------------------- 16.)
