Snes9x is a portable,
freeware Super Nintendo Entertainment System (SNES) emulator. It basically
allows you to play most games designed for the SNES and Super Famicom Nintendo
game systems on your PC or Workstation; they include some real gems that
were only ever released in Japan.
Enable sound CPU emulation
and sound output. (Default)
-ns, -nosound
Disable sound CPU emulation and
sound output, useful for the few ROMs where sound emulation causes them
to lock up due to timing errors.
-sk <0-3>, -soundskip <0-3>
Sound CPU skip-waiting
method. ONLY USED IF SOUND IS DISABLED. Default: 0
-ra 1+, -ratio 1+
Ratio
of 65c816 to SPC700 instructions. Default of 2 is fine for most games, but
3 gets Fifa 96 and games written by the software house Human working. 5
gets The Empire Strikes Back working. There will be others. Default: 2
-h
<0-200), -cycles <0-200>
Percentage of CPU cycles to execute per scan line, decrease
value to increase emulation frame rate. Most ROMs work with a value of 85
or above. Default: 100
-nh, -nohdma
Turn off the H-DMA emulation. Pressing ’0’
during a game toggles H-DMA on and off.
-ha, -hdma
Turn on the H-DMA emulation.
Pressing ’0’ during a game toggles H-DMA on and off. (Default)
-n, -nospeedhacks
Turn off a couple of speed hacks. The hacks boost the speed of many ROMs
but cause problems a few ROMs.
-sh, -speedhacks
Turn on a couple of speed
hacks. The hacks boost the speed of many ROMs but cause problems a few ROMs.
(Default)
-p, -pal
Fool ROM into thinking this is a PAL SNES system and adjust
frame time to 20ms (50 frames per second)
-ntsc
Fool ROM into thinking this
is a NTSC SNES system and adjust frame time to 16.7ms (60 frames per second)
-f <count>, -frameskip <count>
Set this value to deliberately fix the frame skip
rate and disable auto- speed regulation. Use a larger value faster emulation
but more jerky movement and a smaller value for smooth but slower screen
updates. Use ’+’ and ’-’ keys to modify the value during a game. deal for some
Super FX games that confuse the auto-adjust code or for games that deliberately
flash the screen every alternate frame.
-fh, -hr, -hirom
Force Hi-ROM memory
map for ROMs where the Hi-ROM header test fails.
-fl, -lr, -lorom
Force Lo-ROM
memory map for ROMs where the Hi-ROM header test fails
-hd, -header, -he
Force
the detection of a ROM image header. Some ROM images have been hand-edited
to remove unused space from the end of the file; if the resultant image
size is not a multiple of 32k then Snes9x can’t auto-detect the presense
of a 512 byte ROM image header.
-nhd, -noheader
Force Snes9x into thinking
no ROM image header is present. See -header above.
-l, -layering
Swap background
layer priorities from background involved in sub-screen addition/subtraction.
Can improve some games play-ability - no need to constantly toggle background
layers on and off to read text/see maps, etc. Toggle feature on and off
during game by pressing ’8’. Not used if transparency effects are enabled.
-nl, -nolayering
Swap background layer priorities from background involved
in sub-screen addition/subtraction. Can improve some games play-ability - no
need to constantly toggle background layers on and off to read text/see
maps, etc. Toggle feature on and off during game by pressing ’8’. Not used
if transparency effects are enabled.
-tr, -transparency
Enable transparency
effects, also enables 16-bit screen mode selection. Transparency effects
are automatically enabled if the depth of your X server is 15 or greater.
-nt, -notransparency
Disable transparency effects.
-hi, -hires
Enable support
for SNES hi-res. and interlace modes. USE ONLY IF GAME REQUIRES IT (FEW DO)
BECAUSE IT REALLY SLOWS DOWN THE EMULATOR. The window size will be doubled.
-y, -interpolate
Enables ’TV mode’, hires support, 16-bit internal rendering
and transparency effects. TV mode scales the SNES image by x2 by inserting
an extra blended pixel between each SNES pixel and 80% brightness ’scan-lines’
between each horizontal line. The result looks very nice but needs a fast
machine. Use with the full-screen X mode and a 15 or 16 depth X server, or
the SVGA port for fastest operation.
-sc, -scale
Stretch the SNES display
to fit the whole of the computer display. Linux X Window System full-screen
mode or SVGA port only. Use only if you have a very fast machine.
-16, -sixteen
Enable 16-bit internal screen rendering, allows palette changes but no transparency
effects.
-dfr, -displayframerate
Displays the current framerate in the left
bottom corner.
-s, -sw, -swapjoypads
Swaps the both joypads.
-i, -interleaved
Force interleaved ROM image format.
-i2, -interleaved2
Force alternate interleaved
format (i.e. most Super FX games).
-ni, -nointerleaved
Force non interleaved
ROM image format.
-noirq
Disables IRQs. Ignores SNES´ IRQs. Do not use it. It
is implemented mainly for debugging.
-nw, -nowindows
Disable graphics windows
emulation. Use ’backspace’ key during a game to toggle the emulation on and
off.
-windows
Enable graphics windows emulation. Use ’backspace’ key during
a game to toggle the emulation on and off. (Default)
-gg <code>, -gamegenie
<code>
Supply a Game Genie code for the current ROM. Up to 10 codes can be
in affect at once. Game Genie codes for many SNES games are available from:
http://game-genie.nvc.cc.ca.us
-ar <code>, -actionreplay <code>
Supply a Pro-Action
Reply code for the current ROM. Up to 10 codes can be in affect at once.
At the moment, codes which alter RAM do not work.
-gf <code>, -goldfinger <code>
Supply a Gold Finger code for the current ROM. Up to 10 codes can be in
affect at once.
-ft <time_in_ms>, -frametime <time_in_ms>
If auto-adjust frame
skip option is in effect, then the emulator will try to maintain a constant
game and music speed locked to this value by skipping the rendering of
some frames or waiting until the required time is reached. Increase the
value to slow down games, decrease it to speed up games. During a game the
value can be adjusted in millisecond steps by Pressing Shift ’-’ or Shift
’+’. Default: 16.6ms NTSC games and 20ms for PAL games
-e, -echo
Turn on sound
echo and FIR filter effects. Processing these effects can really slow down
a non-MMX Pentium machine due to the number of calculations required to
implement these features. (Default)
-ne, -noecho
Turn off sound echo and FIR
filter effects. Processing these effects can really slow down a non-MMX Pentium
machine due to the number of calculations required to implement these features.
Enable mono sound output. Faster,
but doesn’t sound as nice.
-ex, -envx
Enable volume envelope height reading
by the sound CPU. Can cure sound repeat problems with some games (e.g. Mortal
Kombat series), while causing others to lock if enabled (eg. Bomberman series).
-nc, -nsc, -nosamplecaching
Disable decompressed sound sample caching. Decompressing
samples takes time, slowing down the emulator. Normally the decompressed
samples are saved just in case they need to be played again, but the way
samples are stored and played on the SNES, it can result in a click sound
or distortion when caching samples with loops in them.
-nmv, -nomastervolume
Disable emulation of the sound DSP master volume control. Some ROMs set
the volume level very low requiring you to turn up the volume level of
your speakers introducing more background noise. Use this option to always
have the master volume set on full and to by-pass a bug which prevents the
music and sound effects being heard on Turrican.
-sy, -soundsync
Uses another
method to sync the game and the actual sound.
-sy2, -soundsync2
Uses yet another
method to sync the game and the actual sound.
-is, -interpolatedsound
Enable
sound interpolation.
-ts, -threadsound
If this option is given, snes9x uses
generates another thread, which handles the sound.
-alt, -altsampledecode
If given, Snes9x uses an alternative method to decode the sound.
-nosfx,
-nosuperfx
Forces snes9x to disable SuperFX emulation. By default snes9x
autodetectes if it is needed.
-sfx, -superfx
Forces snes9x to enable SuperFX
emulation. By default snes9x autodetectes if it is needed.
-nodsp1
Forces
snes9x to disable DSP1 emulation. By default snes9x autodetectes if it is
needed.
-dsp1
Forces snes9x to enable DSP1 emulation. By default snes9x autodetectes
if it is needed.
-nmp, -nomultiplayer5
Disables Multiplayer TAP Support.
-mp,
-multiplayer5
Enables Multiplayer TAP Support.
-nm, -nomouse
Disable mouse
emulation.
-mo, -mouse
Enable mouse emulation.
-nss, -nosuperscope
Disable SuperScope
emulation.
-ss, -superscope

-po <port>, -port <port>
Specify what port to connect to. Default: 6096
-srv <hostname>, -server <hostname>
Name of the s9xserver to connect to.
-net
Enable Netplay.
-l <freezegame>, -loadsnapshot
<freezegame>
Load snapshot file and restart game from saved position.
-nojoy
Disable joystick support.
-joydev1 <device>
Supply device for joypad number
1.
-joydev2 <device>
Supply device for joypad number 2.
-joydev3 <device>
Supply
device for joypad number 3.
-joydev4 <device>
Supply device for joypad number
4.
-joymap1 <8 numbers>
You can assign the buttons by giving eight number from
0 to 7. Default Map is: 0 1 2 3 4 5 6 7, which corresponds to A B X Y TL
TR Start Select.
-joymap2 <8 numbers>
You can assign the buttons by giving
eight number from 0 to 7. Default Map is: 0 1 2 3 4 5 6 7, which corresponds
to A B X Y TL TR Start Select.
-joymap3 <8 numbers>
You can assign the buttons
by giving eight number from 0 to 7. Default Map is: 0 1 2 3 4 5 6 7, which
corresponds to A B X Y TL TR Start Select.
-joymap4 <8 numbers>
You can assign
the buttons by giving eight number from 0 to 7. Default Map is: 0 1 2 3
4 5 6 7, which corresponds to A B X Y TL TR Start Select.
-nms, -nomodeswitch
The Linux X Windows System port can change the screen resolution when switching
to full-screen mode so the SNES display fills the whole screen. Specify this
option to stop it if causes you problems.
-fs, -fullscreen
Starts up Snes9x
in Fullscreen, if possible.
-b size, -bs size, -buffersize size
Sound playback
buffer size in bytes 128-4096.
-keymap <keymap.ctl>
Use another keymap. Snes9x
tries to load various keymaps, if no parameter is given: /path/to/rom/romname.ctl
(if you used a zip file, it looks inside), ~/.snes96_snapshots/romname.ctl,
/path/to/rom/snes9x.ctl, ~/.snes96_snapshots/snes9x.ctl and if it still hasn’t
found one /usr/share/snes9x/snes9x.ctl.
Snes9x was written by Gary Henderson and Jerremy Koot. It also includes
code from Ivar (Ivar@snes9x.com), zsKnight and _Demo_ and many others. This
manual page was written by Stephen Crowley <crow@debian.org>, for the Debian
GNU/Linux system (but may be used by others). It has been brought up to
