ZSNES by zsKnight, _Demo_, and pagefault with help from Pharos, Teuf, theoddone33 and stainless http://www.zsnes.com ZSNES is a Super Nintendo Entertainment System emulator written mostly in assembler. 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.)

This software also must not be distributed with ROMs. --------------------------------------------------------------------------- 3.) System Requirements --------------------------------------------------------------------------- - Fast Pentium processor strongly recommended - 32MB of RAM - Windows 95/98/ME/2000 or compatible - DirectX 8.0 or higher Recommended System for SFX support : - Fast Pentium processor (P200 - P2-300 (depending on the game)) - 32MB of RAM - Windows 95/98/ME/2000 or compatible - DirectX 8.0 or higher Recommended System for SA-1 support : (Mario RPG) - Fast Pentium processor (P200 or higher) - 32MB of RAM - Windows 95/98/ME/2000 or compatible - DirectX 8.0 or higher Requirements for netplay: - WinSock 2.2 (Included with most Windows versions, or from http://www.microsoft.com/windows95/downloads/ ) Please note that while 32 MB is a recommendation for minimum RAM, additional RAM may be beneficial, especially for 40 or 48 megabit ROMS, or games that require decompression packs. *An FPU is required for DSP1 emulation *You can download directx at www.microsoft.com/directx/ --------------------------------------------------------------------------- 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 - Several special chip emulation routines (SA-1) have unknown bugs to them - 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, Snapshot Format, and FPS counter are available through a menu by pressing F1 during emulation - Screen Snapshot currently saves as Image.BMP (65536 colors). Also, a PNG mode is available that saves in 32 bit ARGB color, as <rom name> <date> <time>.png - FPS counter currently only works when auto frame rate is on. - 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. - There are still many bugs left in ZSNES so don't expect it to run all your favorite games. - 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.) Current Progress --------------------------------------------------------------------------- The following are implemented : - complete 65816 instruction set - SRAM support - LoROM and HiROM support - SlowROM and FastROM support - Full DMA support - HIRQ/VIRQ/NMI Interrupts - Support for most snes file formats - Multi file format support (.1,.2,.3,A.,B.,C.) - Interleaved format support - PAL/NTSC timing support The following are implemented in the new graphics engine 8 bit : - Combination of line by line and tile based graphics engine - Graphic Modes 0,1,2,3,4,5,6,7 - 8x8, 16x16, 32x32 and 64x64 sprite support (flipped in all directions) - 8x8 and 16x16 tiles - 32x32,64x32,32x64,64x64 tile modes - Full HDMA effects for wavy backgrounds, interesting mode 7 effects, etc. - Mode 7 rotating and scaling effects - BG priorities - Sprite Priorities - Add/sub of back area - Mosaic Effects - Offset per tile mode (mode 2/vertical only, Mode 4) - High res 512 resolution and 448/478 vertical resolution - Windowing effects - High res Mode 7 (only in 640x480x256 video mode/disable Eagle/Scanlines) The following are implemented in the old graphics engine : - Line by line based graphics engine - Graphic Modes 0,1,2,3,4,5,6,7 - 8x8, 16x16, 32x32 and 64x64 sprite support (flipped in all directions) - Mosaic effects - 8x8 and 16x16 tiles - 32x32,64x32,32x64,64x64 tile modes - Full HDMA effects for wavy backgrounds, interesting mode 7 effects, etc. - Mode 7 rotating and scaling effects - Single and Dual Windowing Routines - BG priorities - Sprite Priorities - Add/sub of back area - 16-bit graphics support - offset per tile mode (mode 2/vertical only) - High res 512 horizontal resolution (missing in 16x16) Following are present in 16-bit graphics mode : - Palette changing in the middle of a screen - Screen Addition (full and half) - Screen Subtraction (full) - Fixed Color Addition/Subtraction - Window clipping for Fixed Color The following are implemented in the new graphics engine 16 bit : - All of old graphics engine 16bit - Combination of line by line and tile based graphics engine - High resolution mode 7 - High resolution 16x16 tiles for mode 5 - full 15bit color transparencies (instead of the previous 13bit speed hack) for improved picture quality (MMX compatible CPUs only) The following are present in sound : - 16bit digital stereo sound - SPC700 Sound CPU - DSP Sound Processor - Echo Effects - FIR Filter - ADSR volume effects - GAIN volume effects - Noise effects - Pitch Modulation The following are extra features emulated : - Super NES Mouse Support - Super NES Super Scope Support - SuperFX support (Still has a bug or 2 left) - MultiTap (Multiplayer 5) support (4 players on a single computer, 5 players remote (ipx/modem)) - DSP1 emulation (incomplete) - SA-1 emulation (not complete) - OBC1 emulation (still may have bugs) - S-DD1 emulation (through decompression packs) - SPC7110 emulation (also via decompression packs) The following are the features present in ZSNES : - Game State Save (F2=Save, F3=Select, F4=Load). Warning : A state file takes 260 kbytes of HD space! - Auto frame rate to give you constant Super Nintendo speed up to 9 frame skips - configuration file support (ZSNES.CFG) - 2 player support w/ Joystick and Gamepad support The following features are missing : - Pseudo 512 snes horizontal resolution (Haven't seen any game that uses them yet) - Some modes in Offset Per Tile Mode - Some Direct Color Modes (Haven't seen any game that uses them yet) - True SPC7110/S-DD1 decompression What will not run (or not play properly) : - Some Super FX games such as Dirt Trax FX or Winter Gold (causes instability) - Games with unknown co-processors - Games with other special chips such Street Fighter Alpha 2, Momotarou's Happy Train that do not yet have decompression packs. (S-DD1/SPC7110) - Games which doesn't have a valid header - Games that hit a severe bug in the 65816/PPU/SPC700/DSP routines - Games that require special timing - Games that use functions not yet supported by the DSP-1, or that use other flavors of the DSP chip (ex. Top Gear 3000) --------------------------------------------------------------------------- 6.) 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 A,B,X,Y : X,Z,S,A L,R : D,C Start, Select : Enter, RShift ----------------------------...
