Mednafen's Sega Saturn emulation is extremely CPU intensive. The minimum recommended CPU is a quad-core Intel Haswell-microarchitecture CPU with
a base frequency of >= 3.3GHz and a turbo frequency of >= 3.7GHz(e.g. Xeon E3-1226 v3), but note that this recommendation does not apply to any unofficial ports or forks,
which may have higher CPU requirements.
Save states are supported, but the data is not fully sanitized properly on save state load, so definitely avoid loading save states acquired from sources you don't trust(this includes via netplay).
The filenames listed below are per default ss.bios_* settings.
ss.bios_jp | string | | sega_101.bin | Path to the Japan ROM BIOS |
  |
ss.bios_na_eu | string | | mpr-17933.bin | Path to the North America and Europe ROM BIOS |
  |
ss.bios_sanity | boolean | 0 1 | 1 | Enable BIOS ROM image sanity checks. |

  |
ss.cart.ultraman_path | string | | mpr-19367-mx.ic1 | Path to Ultraman ROM image. |
  |
ss.cd_sanity | boolean | 0 1 | 1 | Enable CD (image) sanity checks. |
  |
ss.correct_aspect | boolean | 0 1 | 1 | Correct aspect ratio. Disabling aspect ratio correction with this setting should be considered a hack.
If disabling it to allow for sharper pixels by also separately disabling interpolation(though using Mednafen's "autoipsharper" OpenGL shader is usually a better option), remember to use scale factors that are multiples of 2, or else games that use high-resolution and interlaced modes will have distorted pixels.
Disabling aspect ratio correction with this setting will allow for the QuickTime movie recording feature to produce much smaller files using much less CPU time. |
  |
ss.h_blend | boolean | 0 1 | 0 | Enable horizontal blend(blur) filter. Intended for use in combination with the "goat" OpenGL shader, or with bilinear interpolation or linear interpolation on the X axis enabled. Has a more noticeable effect with the Saturn's higher horizontal resolution modes(640/704). |
  |
ss.h_overscan | boolean | 0 1 | 1 | Show horizontal overscan area. |

Changing Mednafen's output rate, via the "sound.rate" setting, to "44100" may bypass the resampler, which can decrease CPU usage by Mednafen, and can increase or decrease audio quality, depending on various operating system and hardware factors. |

ss.debugger.memcharenc | string | | SJIS | Character encoding for the debugger's memory editor. |
  |
ss.enable | boolean | 0 1 | 1 | Enable (automatic) usage of this module. |
  |
ss.forcemono | boolean | 0 1 | 0 | Force monophonic sound output. |
  |
ss.scanlines | integer | -100 through 100 | 0 | Enable scanlines with specified opacity. Opacity is specified in %; IE a value of "100" will give entirely black scanlines.
Negative values are the same as positive values for non-interlaced video, but for interlaced video will cause the scanlines to be overlaid over the previous(if the video.deinterlacer setting is set to "weave", the default) field's lines. |

ss.shader | enum | none autoip autoipsharper scale2x sabr ipsharper ipxnoty ipynotx ipxnotysharper ipynotxsharper goat | none | Enable specified OpenGL shader. Obviously, this will only work with the OpenGL "video.driver" setting, and only on cards and OpenGL implementations that support shaders, otherwise you will get a black screen, or Mednafen may display an error message when starting up. When a shader is enabled, the ".videoip" setting is ignored. - none - None/Disabled
- autoip - Auto Interpolation
Will automatically interpolate on each axis if the corresponding effective scaling factor is not an integer.
- autoipsharper - Sharper Auto Interpolation
Same as "autoip", but when interpolation is done, it is done in a manner that will reduce blurriness if possible.
- scale2x - Scale2x
- sabr - SABR v3.0
GPU-intensive.
- ipsharper - Sharper bilinear interpolation.
- ipxnoty - Linear interpolation on X axis only.
- ipynotx - Linear interpolation on Y axis only.
- ipxnotysharper - Sharper version of "ipxnoty".
- ipynotxsharper - Sharper version of "ipynotx".
- goat - Simple approximation of a color TV CRT look.
Intended for fullscreen modes with a vertical resolution of around 1000 to 1500 pixels. Doesn't simulate halation and electron beam energy distribution nuances.

ss.shader.goat.fprog | boolean | 0 1 | 0 | Force interlaced video to be treated as progressive. When disabled, the default, the "video.deinterlacer" setting is effectively ignored with respect to what appears on the screen. When enabled, it may be prudent to disable the scanlines effect controlled by the *.goat.slen setting, or else the scanline effect may look objectionable. |
  |
ss.shader.goat.hdiv | real | -2.00 through 2.00 | 0.50 | Constant RGB horizontal divergence. |
  |
ss.shader.goat.pat | enum | goatron borg slenderman | goatron | Mask pattern.- goatron - Goatron
Brightest.
- borg - Borg
Darkest.
- slenderman - Slenderman
Spookiest?
|
  |
ss.shader.goat.slen | boolean | 0 1 | 1 | Enable scanlines effect. |
  |
ss.shader.goat.tp | real | 0.00 through 1.00 | 0.50 | Transparency of otherwise-opaque mask areas. |
  |
ss.shader.goat.vdiv | real | -2.00 through 2.00 | 0.50 | Constant RGB vertical divergence. |
  |
ss.special | enum | none hq2x hq3x hq4x scale2x scale3x scale4x 2xsai super2xsai supereagle nn2x nn3x nn4x nny2x nny3x nny4x | none | Enable specified special video scaler. The destination rectangle is NOT altered by this setting, so if you have xscale and yscale set to "2", and try to use a 3x scaling filter like hq3x, the image is not going to look that great. The nearest-neighbor scalers are intended for use with bilinear interpolation enabled, at high resolutions(such as 1280x1024; nn2x(or nny2x) + bilinear interpolation + fullscreen stretching at this resolution looks quite nice). - none - None/Disabled
- hq2x - hq2x
- hq3x - hq3x
- hq4x - hq4x
- scale2x - scale2x
- scale3x - scale3x
- scale4x - scale4x
- 2xsai - 2xSaI
- super2xsai - Super 2xSaI
- supereagle - Super Eagle
- nn2x - Nearest-neighbor 2x
- nn3x - Nearest-neighbor 3x
- nn4x - Nearest-neighbor 4x
- nny2x - Nearest-neighbor 2x, y axis only
- nny3x - Nearest-neighbor 3x, y axis only
- nny4x - Nearest-neighbor 4x, y axis only

ss.stretch | enum | 0 full aspect aspect_int aspect_mult2 | aspect_mult2 | Stretch to fill screen.- 0 - Disabled
- full - Full
Full-screen stretch, disregarding aspect ratio.
- aspect - Aspect Preserve
Full-screen stretch as far as the aspect ratio(in this sense, the equivalent xscalefs == yscalefs) can be maintained.
- aspect_int - Aspect Preserve + Integer Scale
Full-screen stretch, same as "aspect" except that the equivalent xscalefs and yscalefs are rounded down to the nearest integer.
- aspect_mult2 - Aspect Preserve + Integer Multiple-of-2 Scale
Full-screen stretch, same as "aspect_int", but rounds down to the nearest multiple of 2.

  |
ss.tblur | boolean | 0 1 | 0 | Enable video temporal blur(50/50 previous/current frame by default). |
  |
ss.tblur.accum | boolean | 0 1 | 0 | Accumulate color data rather than discarding it. |
  |
ss.tblur.accum.amount | real | 0 through 100 | 50 | Blur amount in accumulation mode, specified in percentage of accumulation buffer to mix with the current frame. |
  |
ss.videoip | enum | 0 1 x y | 1 | Enable (bi)linear interpolation.- 0 - Disabled
- 1 - Bilinear
- x - Linear (X)
Interpolation only on the X axis.
- y - Linear (Y)
Interpolation only on the Y axis.

  |
ss.xres | integer | 0 through 65536 | 0 | Full-screen horizontal resolution. A value of "0" will cause the current desktop horizontal resolution to be used. |
  |
ss.xscale | real | 0.01 through 256 | 3.000000 | Scaling factor for the X axis in windowed mode. |
  |
ss.xscalefs | real | 0.01 through 256 | 1.000000 | Scaling factor for the X axis in fullscreen mode. For this setting to have any effect, the ".stretch" setting must be set to "0". |
  |
ss.yres | integer | 0 through 65536 | 0 | Full-screen vertical resolution. A value of "0" will cause the current desktop vertical resolution to be used. |
  |
ss.yscale | real | 0.01 through 256 | 3.000000 | Scaling factor for the Y axis in windowed mode. |
  |
ss.yscalefs | real | 0.01 through 256 | 1.000000 | Scaling factor for the Y axis in fullscreen mode. For this setting to have any effect, the ".stretch" setting must be set to "0". |
