The Sega Saturn is a 32-bit, fifth-generation console released by Sega in Japan on November 22, 1994 and in the US on May 11, 1995. It was retailed for $399.99 ($869 in 2026). It had 2 Hitachi SH-2 CPUs at 28.6 MHz and it had the VDP1 GPU & VDP2 GPU. The arcade board, ST-V (Sega Titan Video), uses the same hardware except for sound, VRAM, and game storage (where it is stored on ROM cartridges with most games instead of CD-ROM discs).

The Sega Saturn has historically been one of the harder consoles to emulate due to its infamously difficult architecture consisting of 8 processors overall and use of quadrilaterals rather than triangles as polygons, resulting in a lack of good options. However, things are looking up for open-source emulators like Mednafen, and to a lesser extent, Yabause. Recently, a matchmaking service for Saturn has been established.

Comparisons

Mednafen

An open-source, multi-system emulator with an original Saturn core. It's currently the most accurate but runs from the command-line (obviously it'll have video output though) unless using an external frontend like Mednaffe or a libretro frontend like RetroArch. Its goal for accuracy means it only supports the BIOS of one console revision per region, and is also more demanding than any other Saturn emulator (other than MAME). By default, only x86-64 builds have Saturn support, but unofficial x86-64 builds and libretro frontends like RetroArch can surpass this limitation.

SSF

Used to be the emulator of choice for compatible Saturn emulation. However, it is closed-source and only for Windows and Android. Pretty good performance with low-end computers.

• City Connection uses SSF as part of Zebra Engine, the engine behind their Saturn Tribute releases, currently for Switch, PS4, Xbox One and PC. Some games are altered with English translations (Assault Suit Leynos 2) or with censorship from CERO (Idol Janshi Suchie-Pai series).

Yabause

Used to be the first and only option for multi-platform Saturn emulation. It's far less developed than SSF and Mednafen and still has many compatibility issues. Development seems to have stopped, active forks are Libretro core, Kronos and Yaba Sanshiro 2.

Yaba Sanshiro 2 (formerly uoYabause)

A Multi-platform fork by DevMiyax using OpenGL ES 3.X (Android), and Open GL 3.X (Windows). Unlike other forks, it uses the GPU to emulate the VDP1, VDP2, and has a modified SH2 Dynamic Recompiler. It offers good out-of-the-box experience (easy setup and included frontend), but average accuracy.

Kronos

A fork of UoYabause 0.5.2 created by François (French dev. AKA 'FCare'.). Has his own written SH2 Interpreter, and now supports the ST-V arcade in version 1.30, and Higher (All ST-V games are launchable on Linux; most games are still problematic on Windows).

Ymir

An emerging emulator that focuses on ease of use and quickly catching up to established Saturn emulators.

MAME

Has a saturn driver with compatibility on par with Yabause. The driver is marked overall as not working but graphics and sound are OK. It has good compatibility with at least around 50 of the ~70 ST-V arcade games, though performance quality may vary. But versions 0.158. (Jan 2015) to much later have made good advances in performance. Early known work on ST-V hardware emulation was done in various builds of 0.125, 0.133, 0.138, 0.142 & 0.143 (See prior builds) between 2008-2011. Even bug fixes and more graphical improvements were included in the years 2017-2018 (i.e. 0.191, 0.197 & 0.198).

Nova

An up-and-coming emulator still under heavy development focused on being fast, compatible, and user-friendly. Like SSF, it is closed-source and Windows only. From v0.2.1 onwards, it can now emulate the Sega Titan Video (ST-V) arcade hardware (e.g. Guardian Force on ST-V in v0.2.2.).

BizHawk

An open-source, multi-system emulator designed for tool-assisted speedruns. Its Saturn core is based on Mednafen.

Comparisons of several Saturn emulators

• A Deep Dive into the Sega Saturn and Saturn Emulation (By Dolphin tester, JMC47, AKA Justin M. Chadwick. 13 OCTOBER 2017. Tested emulators: Yabause & uoYabause, SSF (unofficial site), and Mednafen. Already outdated the next year by progress in the Kronos fork).

Name		Mednafen	Ymir	Kronos	Nova	BizHawk	SSF	Yaba Sanshiro 2
Controls	Input lag mitigating	?	?
	Mouse injector	✗	?
	Turbo button	?	?
Graphics	Pre-rendering anti-aliasing (MSAA, SSAA)	?	✗
	Resizable internal resolution	✗	✗

	Widescreen hack	?	✗
	Dithering / Transparent Mesh Polygon Rendering	?	✓
Performance	Frame generation technologies (LSFG, DLSS-FG and SM, XeSS-FG, AFMF and FSR FG)	Implementing frame generation technology in an emulator is unfortunately quite challenging and unlikely to be feasible in the near future, however post-processing techniques such as motion interpolation is quite possible. Input latency will be a crucial factor, but its impact likely varies depending on the specific technique employed, it's recommended to use after applying the "Internal frame rate hack". While AFMF or LSFG could be used with Mednafen?, please be aware that some visual glitches and artifacts may occur at this time.
	Internal frame rate hack	?	✗
	Overclock	?	✓
	Preload optical disc image to RAM For users with sluggish multi-platter HDDs or plagued by horrible seek times, this enhancement might offer smoother experience, potentially reduced power consumption; it also shines when disc images reside on a network drive. Although keep in mind that preloading image would take some time, and it will require additional amount of RAM capacity.	✓*	✓
Post-processing	AI-powered filter (Freestyle)	?	✗
	Deinterlacing / Progressive Scan Option to force progressive output for high-res (480i) titles to eliminate interlaced "combing" artifacts.	~	✓*

	Built-in cheat manager	~	✗
	Built-in custom resolution/CRTSwitchRes For using this on Windows OS you need CRT Emudriver. Another option is using EDID editor tool such as "Custom Resolution Utility".	Exclusive to libretro cores and GroovyMAME at the moment. Also there is a project for achieving software emulators like libretro cores and GroovyMAME send the raw RGB data over a network to a core running on MiSTer, it basically turns the MiSTer into a GPU for the emulator allowing for easy setup and use with CRT TVs/Arcade monitors.

	Built-in save manager	?	✓
	Command-line options	?	✓
	Pause/Resume emulation	✓	✓
	Per-game profiles	?	?
	Portable and stealth Useful enhancement feature for non-personal computer use or plug-and-play scenarios. However, the software may still require the necessary prerequisites and dependencies for your operating system if it is not statically linked.	✓	✓
	Streamable compression format	?	✓
	Variable refresh rate	~	✓

Misc.	Ambient sounds simulation Simulation of audio from original hardware and environments, such as mechanical hard drive, floppy diskette, and optical drive noises (e.g., head seeks, spin-up/down, tray loading, disc spinning, and clicking), variable CRT flyback transformer whine (the classic high-pitched "coil whine" that dynamically changes pitch based on screen brightness and content), arcade cabinet effects (e.g., fan hum or button rattles), and other background ambient noises.	✗	✗
	Audio filters and presets Simulation of characteristic playback limitations and coloration of vintage consumer audio hardware, such as CRT television speakers, arcade cabinets, handheld consoles, early PC sound outputs, and low-fidelity integrated speakers. These filters are not intended to be perfectly accurate recreations, but rather to evoke the tonal qualities, distortion, bandwidth limits, resonance, and compression associated with 8-bit and 16-bit era devices. Examples include mono or narrow stereo output, reduced frequency response, speaker cone distortion, mild saturation, aliasing, and preset lo-fi profiles inspired by classic TVs, portable game systems, radios, and retro multimedia hardware.	Exclusive to libretro cores at the moment.
	Debug features	?	✓
	EmuVR support	Exclusive to libretro cores at the moment.
	Free Look Free Look is a enhancement feature that allows manipulation of the in-game camera.	While freecam would be technically possible, it will require per-game patches. Said patches would require a significant amount of time to reverse the game's engine, which means that only someone talented with enough dedication to a single game could do it.
	Netplay Should not be confused with Sega Net Link emulation, see hardware features and peripherals.	✓	?
	RetroAchievements	~	✗
	Rich Presence (RPC) Allows the emulator to share real-time game session details (e.g., current game title, level, boss, playtime, or custom status) with external applications. This enables features such as displaying what you're playing on your profile, inviting friends to spectate, or triggering join-in-progress functionality where supported.	?	?
	Screen translator Using optical character recognition (OCR) and other techniques, this feature can provide live translation of in-game text, text-to-speech for visually impaired users, and more — either on demand or automatically.	You can use RetroArch's AI Service or the standalone offline bquenin's Interpreter.

Video CD Card

Saturn Video CD Card emulation using Nova emulator (partially supported)

Also called the Movie Card in Japan - allows Saturn to play Photo CDs, Video CDs (VCDs) and also hardware playback of MPEG-1 (version 1) video in certain games, leading to higher quality FMV for use in cutscenes (and occasionally, gameplay) (similarly to the Philips CD-i's Digital Video Cartridge). Later revisions of the Video CD Card negate the need for Photo CD Operator software by giving the Saturn native Photo CD support.

See this dedicated page for more information about home media playback support for emulation softwares.

Taisen Cable

Sega Retro: Taisen Cable compatible games

The Taisen Cable is a peripheral which allows two Sega Saturns to connect to each other. It can be seen as a console equivalent to serial networking usually found with computers, where systems are all linked together within a small area. The official Sega-branded Taisen Cable was only released in Japan, however third-party alternatives were released in other territories and a number of non-Japanese games support the device.

Sega Titan Video

Mednafen version 1.31.0 added experimental support for ST-V games that don't require decryption chips or special hardware. Refer to the ST-V section of the official documentation for more details and a list of explicitly supported games.

• MAME 0.289 version is currently one of the best emulator for ST-V emulation but still "Imperfect".
