ZSNES is an emulator for the Super Nintendo video game console. It is written in a combination of x86 assembly, C, C++, and PSR. It is currently available on Windows, DOS, x86 Linux, x86 Mac OS X, and x86 BSD.

Visit http://www.zsnes.com/ for the latest updates.

Note: Many of these options can also be set in the GUI.

-zs #

Auto load specified save state on startup, where # is a numerical value from 0\[en]99

romname

Name of ROM to auto\[hy]load romname is of the format filename.ext, where .ext is one of SMC, SFC, SWC, FIG, MGD, MGH, UFO, BIN, GD3, GD7, USA, EUR, JAP, AUS, ST, BS, DX2, 048, 058, 078, 1 or A. You can also load ROMs which have been compressed with GZip, Zip or JMA.

ZSNES

The main program.

~/.zsnes

This is the directory where ZSNES configuration files are stored. By default, it is also the directory where save states, screenshots, SPC dumps and ZMV movie files are stored, but you can change this behaviour by editing zsnesl.cfg. This directory is created by ZSNES.

~/.zsnes/zsnesl.cfg

This file is where configuration settings for ZSNES are stored. It is in a human\[hy]readable format and can be edited by hand. It is created by ZSNES.

~/.zsnes/zmovie.cfg

This file is where settings specific to AVI dumping are saved. It is created by ZSNES.

~/.zsnes/zfont.txt

This file allows you to customize the fonts in the GUI. Enable "Use Custom Font" in the GUI Options menu. It is created by ZSNES.

~/.zsnes/zinput.cfg

This file is where input configuration settings for ZSNES are stored.

If for some reason you update your version of ZSNES and it keeps crashing before you can do anything, you should try deleting the above .cfg files and let ZSNES create new ones.

Many games on the Super Nintendo used custom CPUs in addition to the main SNES CPU. Some of these CPUs have not been fully reverse\[hy]engineered, and games that use them may either not work or may experience strange bugs.

You can find more information about these special CPUs at:

http://users.tpg.com.au/advlink/dsp/

http://nsrt.edgeemu.com/INFO/chipinfo.htm

Some games based on the SPC7110 chip, such as Far East of Eden Zero, can use special graphics packs to work around unemulated portions of their custom CPU. These graphics packs must be stored in individual directories within the save directory, which is specified in zsnesl.cfg. By default, this is ~/.zsnes. The directory name of each graphics pack must be capitalized and all files within that directory must be in lowercase.

The proper directory name for a given graphics pack can be found in the readme file included with that pack.

NOTE: As of version 1.40, games which use the S\[hy]DD1 chip (Star Ocean and Street Fighter Alpha 2) do not require graphics packs.
