What you will need ------------------ NLKSNES is quite possibly the fastest SNES emulator in existence. However, you must configure it and your system properly to achieve maximum speed. On an Intel 486DX2-66 will sometimes run up to 60%, or even 70%, depending on the ROM image used. Access to SNES ROM images in *.smc format will also help otherwise you will have nothing to run! Some commercial ROM images are available via the Internet, try following links from: http://moon.inf.uji.es/~pocket Please note it is illegal in most countries to have commercial ROM images without also owning the actual SNES ROM cartridge. Starting the emulator --------------------- From a shell or DOS session just type: nlksnes A command line flag is available: -joy : Support for joystick or paddle -nirq : Disable IRQ See "Compatibility" -frame value (1) : Skip Frames See "Speeding up the Emulation" below -bpatch bank:offset:value : Patch a byte in memory -wpatch bank:offset:value : Patch a word in memory -delay value : Delay a time (Only in NLKSNES!) While the emulator is running: 'Escape' quit the emulator Joy-pad 1: 'up' Up direction 'down' Down direction 'left' Left direction 'right' Right direction 'e' L button 'r' R button 'x' X button 'd' Y button 'z' A button 's' B button 'b' Start button 'v' Select button Now you can define the keys, execute "keycfg.exe" included in the emulator. This version support for one, 2 or 4 button joystick. A patch option has been added for problems with SPC700, see "Compatibility" Speeding up the Emulation ------------------------- 1) Try the following command line flags: -frame (default 0: every frame is rendered and displayed) Increasing this value will speed up the emulator but make screen updates more jerky. 2) Buy a higher processor Spc700 Emulation ---------------- This emulation is being programmed. So, Don't ask us for sound emulation.
