Introduction

NOTE: The Sega Saturn emulation is currently 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.

Firmware/BIOS

Place the correct BIOS image files in the correct location. If you don't intend to emulate the arcade ST-V at all, you don't need to provide the corresponding ST-V BIOS files.

The filenames listed below are per default ss.bios_* settings.

Filename:	Purpose:	SHA-256 Hash:
sega_101.bin	BIOS image. Required for Japan-region games.	dcfef4b99605f872b6c3b6d05c045385cdea3d1b702906a0ed930df7bcb7deac

NOTE: The default mapping for the emulated mouse "START" button conflicts with the default mapping for the "Enter" key on the emulated keyboards on all virtual ports, and the default mapping for "START" on the emulated digital gamepad on virtual port 1. If you want to use an emulated mouse with an emulated keyboard, you should probably remap the "START" button to a non-keyboard host device.

ST-V

Mednafen has experimental support for ST-V games that don't require special expansion hardware nor use a decryption or decompression chip. ST-V-specific BIOS files are required. The games should be loaded via ZIP archives, one variant of one game per archive, with all ROM image files in the same directory in the archive, and ideally with no extraneous files that may confuse autodetection. Lowercase MAME-style filenames must be used. For testing purposes, an ST-V game outside of an archive may also be played by loading the first boot/program ROM image file.

Upon loading a supported ST-V game, a suitable emulated Saturn input device is selected automatically, and input data is remapped internally to the form the emulated ST-V hardware needs. For most games, the device selected is the Digital Gamepad("gamepad"), but for "Critter Crusher" and "Tatacot", it is Light Gun("gun").

ST-V Service, Test, and Pause currently cannot be remapped inside Mednafen itself, due to limitations that may be resolved in a future version. They can still be remapped manually, however.

Default Key Mappings:

Bootable ROM Cart

Mednafen supports bootable cart ROM images up to 48MiB in size, with a filename extension of "ss".

The first 32MiB is mapped into A-bus CS0, and the ROM data beyond 32MiB is mapped into A-bus CS1; both are mapped as 16-bit ROM. If the ROM image is 32MiB or smaller, a standard 512KiB of non-volatile cart backup memory will be provided in the A-bus CS1 area instead of ROM data.

Internal Databases

Region

This database is used in conjunction with a game's internal header and the "ss.region_default" setting to automatically select the region of Saturn to emulate when the "ss.region_autodetect" setting is set to "1", the default.

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.

For ST-V games, this database is not used, and instead full cache emulation is always enabled.

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.

For ST-V games, this database is not used, and instead VDP1 command slowdown on SH-2 reads/writes is always enabled.

Game:	ID:	Horrible Hacks:	Purpose:
Albert Odyssey (Japan)	T-1507G	SH-2 reads/writes from/to VDP1 slow down command execution.	Partially fixes battle text truncation.
Albert Odyssey (USA)	T-12705H	SH-2 reads/writes from/to VDP1 slow down command execution.	Partially fixes battle text truncation.

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).

Setting:	Value Type:	Possible Values:	Default Value:	Description:
ss.affinity.vdp2	integer	0x0000000000000000 through 0xFFFFFFFFFFFFFFFF	0	VDP2 rendering thread CPU affinity mask. Set to 0 to disable changing affinity.

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.scsp.resamp_quality	integer	0 through 10	4	SCSP 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.

ss.slend	integer	0 through 239	239	Last displayed scanline in NTSC mode.

ss.slendp	integer	-16 through 271	255	Last displayed scanline in PAL mode.

Setting:	Value Type:	Possible Values:	Default Value:	Description:
ss.debugger.disfontsize	enum	5x7 6x9 6x12 6x13 9x18	5x7	Disassembly font size. Note: Setting the font size to larger than the default may cause text overlap in the debugger. 5x7 - 5x7 6x9 - 6x9 6x12 - 6x12 6x13 - 6x13. CJK support. 9x18 - 9x18; CJK support.

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 "ss.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, unless it's set to "blend" or "blend_rg". When enabled, it may be prudent to disable the scanlines effect controlled by the "ss.shader.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, for a sharper image, though the "autoipsharper" shader may provide better results. 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.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 "ss.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 "ss.stretch" setting must be set to "0".
