Introduction

NOTE: The Sega Saturn emulation is currently experimental and under active development. By default(and for the official releases for Windows), Saturn emulation is only compiled in for builds for some 64-bit architectures(x86_64, AArch64, PPC64). The separate SSF playback module does not have this limitation.

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).

Enabling CD image preloading into memory via the cd.image_memcache setting is recommended, to avoid short emulator pauses and audio pops due to waiting for disk accesses to complete when the emulated CD is accessed.

A list of known emulation bugs(with workarounds in some cases) in Saturn games with Mednafen is available at https://forum.fobby.net/index.php?t=msg&th=1357

Mednafen's Sega Saturn emulation should not be used in lieu of a Sega Saturn for authoritative game performance/FPS review purposes. The emulation will generally run Saturn games with less slowdown than on a real Saturn, even when more accurate emulation modes are enabled via internal databases.

If a game is not found in the database when auto selection is enabled, then the cart used is specified by the "ss.cart.auto_default" setting, default "backup"(a backup memory cart).

Cache Mode

This database is used to automatically select cache emulation mode, to fix various logic and timing issues in games. The default cache mode is data-only(with no high-level bypass).

The cache mode "Data-only, with high-level bypass" is a hack of sorts, to work around cache coherency bugs in games. These bugs are typically masked on a real Saturn due to the effects of instruction fetches on the cache, but become a problem when only data caching is emulated.

Full cache emulation is not enabled globally primarily due to the large increase in host CPU usage.

Horrible Hacks

This database is used to automatically enable various horrible hacks to fix issues in certain games.

Note that slowing down VDP1 command execution due to SH-2 reads/writes isn't a horrible hack per-se, but it's activated on a per-game basis to avoid the likelihood of breaking some games due to overall Saturn emulation timing inaccuracies.

Settings Reference

Caution: Any settings that change emulation behavior as seen from the emulated game are shown with the setting name bolded in the table. One should be conscious of these settings if one has changed them from the default values when using network play or movies, as they can cause desychronizations if not set the same among hosts(or between the recording emulator and the playing emulator).

1Correct 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.scsp.resamp_qualityinteger0 through 104SCSP output resampler quality.

0 is lowest quality and CPU usage, 10 is highest quality and CPU usage. The resampler that this setting refers to is used for converting from 44.1KHz to the sampling rate of the host audio device Mednafen is using. 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.

goat
noneEnable 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.

0Force 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, unless it's set to "blend" or "blend_rg". 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.

noneEnable 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

  • 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.xresinteger0 through 655360Full-screen horizontal resolution.

A value of "0" will cause the current desktop horizontal resolution to be used.

ss.xscalefsreal0.01 through 2561.000000Scaling factor for the X axis in fullscreen mode.

For this setting to have any effect, the ".stretch" setting must be set to "0".

A value of "0" will cause the current desktop vertical resolution to be used.
