Title Description Author
Chankast This is the first Dreamcast emulator ever to play commercial games at a decent speed. Be warned though, as a 2GHz processor is recommended. The Capcom hack has now been integrated into the main binary.
DEmul DEmul is a dreamcast emulator capable of running many games at very fast speeds.
DreamEMU Currently shows the Sega opening screen and runs some demos slowly.
Dreamer This is the first attempt at an emulator for the Sega Dreamcast. It only runs several demos. No progress has been made in quite some time.

A-SATURN This Saturn emulator emulates 99% of the main CPUs and various percents of the other chips. It doesn't run any games however.
Cassini Cassini is a new Saturn emulator for Windows that now has a slew of controversy around it. There are claims from many sides about the legality of it and many sides concerning simply the morality and ethics involved. It is a hacked version of GiriGiri. Until this emulator has been deemed illegal, we'll provide a download. Not sure how long that might be, so you may want to get it now. As with all Saturn emulators, a Saturn BIOS is needed.
GiriGiri Debugger GiriGiri the Sega Saturn Emulator, as people like to call it, now runs commercial games! However, it has also become the commercial GiriGiri Saturn, so don't look for the newest versions here.
Hyperion Hyperion is a discontinued emulator that can only display the Saturn menus and the Saturn CD Player.
PC-Saturn PC-Saturn is another Saturn emulator that was discontinued before doing much.
Project Titan This emulator is quite primitive and really isn't useful for much. It's open source though, so you can look at that if you wish.
Sat'On'Em This was a close competitor with A-Saturn, but has been discontinued. Sat'On'Em emulates 89% of both the CPUs, and it fully emulates the memory.
Satan Althogh Satan is nothing more than a Saturn CD header reader, this was the first legitimate Saturn emulator ever to come into existence. Coded by Nakasaki, this emulator has its own install program. It doesn't emulate anything, but can read CD info such as the Virtual Fighter Remix CD.
Satourne This emulator has come a long way, and plays a few games. Definitely give it a try!
Saturnin Saturnin is developed by Runik and is one of the major Saturn emulators out there. It can play some commercial Saturn Roms.
SSE SSE is a Sega Saturn and ST-V emulator that appeared out of nowhere after a year of development and can play several games. Give it a try and visit its official page for more in depth info.
SSEmu This was the first Sega Saturn emulator to actually emulate something. It emulates the Saturn Control Unit (SCU), all three Hitachi processors (partially), and music is emulated (CD-Audio). It has been discontinued, however.
SSF SSF has been in development for quite some time now, and can play many commercial games.
UltraSat UltraSat can't play any games, but can read the copyright information from 15 different games. It has been discontinued.
Yabause Yabause is a Sega Saturn emulator under GNU GPL. It currently runs on FreeBSD, GNU/Linux, Mac OS X, Windows, Dreamcast, and Wii.
Yabause rr Yabuse rr supports a lot of video recording features the vanilla build of the emulator does not.

Genesis / Sega CD / 32X

Title Description Author
Kega Fusion Fusion is a Sega SG-1000, SC-3000, SF-7000, Master System, GameGear, MegaDrive/Genesis, MegaCD/SegaCD, 32X, CD+32X, Pico, and Virtua emulator for Windows, MacOSX, and Linux.
Ages Ages is a SEGA Genesis, SEGA 32X, and Sega CD emulator. Compare it to your favorite SEGA Genesis emulator and send your thoughts to the authors. This emulator has full sound, and has been built from scratch.
DGen DGen has good sound, and runs well on a P2-233 and higher. DGen has pretty good compatability but is greatly out matched in quality by newer emulator suck as Gens and Kega compatibility.
Genecyst Genecyst was once the best Genesis emulator but is now sorely beaten by many others. The only point it its favour is its blazing speed which has become legendry. Well worth a download for some nostalgia.
Generator Generator uses it's own custom 68000 processor emulation which is designed for dynamic recompilation, and uses techniques from this such as block-marking, flag calculation removal, operand pre-calculation, endian pre-conversion etc. There are approximately 1600 C routines generated by the first stage of compilation to cope with the 67 instruction families. These routines are used as a 'backup' when dynamic recompilation isn't supported on your platform or the recompiler doesn't support a particular instruction. The CPU engine is by all accounts very fast, whatever the mode.
Genesis Plus This is a new emulator from Charles MacDonald, the author of SMS Plus. It is an open-source emulator, which supports sound, joysticks, and other fun stuff. Note: The Windows version is significantly less-featured than the DOS version, it doesn't support joysticks or audio yet, and it only runs windowed on a 16-bit desktop.
Genital Genital runs a decent amount of games if you have a PC with a Pentium processor or better. However, it's now discontinued and never got sound support.
Gens Gens has a high compatibility rate and good speed. It also has many nice features including a multi language menu, netplay with Kaillera, great SEGA-CD support and now 32x emulation too! The Genecyst of today. It's either this or Kega.

The DOS version of Gens has a lower compatibility rate, less speed, and the sound only partially works. It's discontinued.

Gens Plus! Gens Plus! is a Sega Genesis / 32X / SegaCD / Master System / Game Gear emulator based on the Gens emulator that has added features.
Gens+ REWiND! Gens+ REWiND! is a Sega Multisystem emulator which supports the following systems:

SEGA Master System (SMS) SEGA Game Gear (GG) SEGA Genesis/Mega Drive (SMD) SEGA Genesis 32X (32X) SEGA SegaCD/MegaCD (SCD)

With the current release Gens+ evolved with the following feature: Rewind

Gens/GS Gens/GS is a version of Gens maintained by GerbilSoft. The main goal of Gens/GS is to clean up the source code and combine features from various forks of Gens.
Gens32 Based on Gens 2.12a and Gens+, Gens32 is a Sega Genesis/32X/SegaCD emulator for Win32. It allows you to play games developed for these classic SEGA consoles on your x86 compatible PC.

It runs under Windows 95/98/ME/2000/XP and requires DirectX 7.0 or above to be installed on your system. Gens32 is currently discontinued since the project evolved into Gens32 Surreal.

Gens32 Surreal A revamped version of Gens32. It has a smoother frame rate and an advanced sound configuration system.
Kega From the author of the amazing DOS Genesis emulators KGen98 comes a brand new Windows Genesis emulators, Kega. It runs under Windows 95/98/ME/2000/XP, has support for Sega CD, and requires DirectX8 or above to run. The KGen of today. It's either this or Gens.
KGen This is the predecessor of KGen98 and Kega. It's not as good as either of them so you may want to skip this.KGen98 is basically a total rewrite of KGen. It's similar to Genecyst but with slightly better compatability and accuracy. Plus, with 8-bit graphics and no VSync, it's reported to be faster than Genecyst. Still, Gens and Kega are better so you may want to skip this too...
Megadrive Discontinued due to a hard drive crash (in pre-ZD times), this emulator is capable of playing Sonic the hedgheog very slowly with no sound and many glitches, and it can do very little else. This isn't worth the download.
Megasis Megasis is a good Genesis emulator, however the speed leaves a lot to be desired. It features proper emulation of some games that other emulators may fall short on (e.g. Warsong). It also has decent sound emulation. If you have a fairly fast computer, you might want to give it a try.
Regen Very good Sega Genesis/MegaDrive emulator runs many games with or very close to 100% compatibility.

A Linux port is also available.

retroDrive Formerly "GenSX", formerly "Vegas", this was the public's first 32x emulator ever. It also runs Genesis games very well. A Pentium II or better is recommended.
SEGAEmu SEGAEmu emulates the Sg-1000, Sega Master System/Game Gear, Sega CD, and SEGA Genesis, but we will keep it here on the SEGA Genesis emulators page for now. Try it out, it might become one of your favourites! You can download plugins for the emulator at www.atani-software.netThe Emulator translated to Norwegian.The Emulator translated to French.
st0rm st0rm is a primitive emulator that has a compatibility rate of less than 50%. There is no sound, and it's very slow.The source is now available, since the project is basically been discontinued.
VGEN Virtual Genesis, or VGEN for short, is a decent Genesis emulator. It has both the PSG and YM2612 emulated, so it has pretty good sound support. It can run a decent number of games, but not as many as Gens or Kega. Some games are very glitched. This was also the first emulator with preliminary Sega CD support. You'll need one of the Sega CD BIOS images to test it out. It can only show the bootup screen. It has been discontinued.
Xega Xega requires DirectX 8.0. It has sound and plays commercial games. Good support for Sega CD and 32X.

Master System/Game Gear

Title Description Author
BRSMS This is a Sega Master System and Game Gear emulator. It runs full speed on a 486 DX-66, and has sound emulated, including voice support. Most games are playable, although a few still do not work correctly. It even has serial cable support! It's definitely worth a download for those with slow computers, as well as those who want a great SMS/GG emulator which does not cost any money.
Calypso Here's the newest of the SMS/GG emulators, and this one (while it doesn't look like much now) has high hopes. The author wants it to become a multi-emulator for all Sega systems in existance. Currently, it has relatively low compatibility, some sound support, and uses the RAZE Z80 engine. Give it a try.
CHASMS This fairly recent emulator, coded by the author of the Verge RPG-creation engine, is a promising new SMS/GG emulator with a GUI that resembles the old NESticle GUI. While it's nowhere as good as MEKA yet, it has a number of features that MEKA doesn't have, such as a Pro Action Replay cheat finder. This looks to be one of the better emulators available.
Cogwheel A software emulator primarily for 8-bit Sega hardware, such as the Sega Master System, Sega Game Gear and SG-1000. The ColecoVision is also supported.

The project uses a modular design based around a Z80 core emulator class library. The rest of the Sega-specific emulation is implemented in another class library, and the user interface is implemented as a separate application. This would allow the main emulator to be easily adapted to different interfaces.

The code is written in C#3 (targetting .NET 2.0). The user interface uses Windows Forms, with SlimDX being used to render the graphical output to the form as quickly as possible.

Dega Dega is a Sega Master System and Game Gear emulator, which runs under Windows 95, NT, 98, 2000, ME or XP.
Emukon Emukon (formerly known as eSMS) is a Sega Master System and Game Gear emulator. It runs on Windows and needs DirectX7.0+. It includes a nice GUI, a cool debugger and some video filters. It runs most games flawlessly if your computer is fast enough.
FoolsSMS Sega Master System emulator written using Marat's old z80 core. The compatibility is high, but the emulator has no sound.
FreezeSMS FreezeSMS is an SMS emulator that already has high compatibility and a reasonable speed.
Gens Plus! Gens Plus! is a Sega Genesis / 32X / SegaCD / Master System / Game Gear emulator based on the Gens emulator that has added features.
GGBoy This is a Game Gear emulator made by Maechiko (author of *Fan emulators) with a nice interface and decent speed. Try it out.
HiSMS This is a Master System emulator with a twist. The goal here is to replace the tilesets of the SMS games with hi resolution recreations of the originals.
Kega Fusion Fusion is a Sega SG-1000, SC-3000, SF-7000, Master System, GameGear, MegaDrive/Genesis, MegaCD/SegaCD, 32X, CD+32X, Pico, and Virtua emulator for Windows, MacOSX, and Linux.
Massage This is the Final release of Massage, it now has some preliminar support for Sega SG computers family. (Rename the files to .SMS).
MasterGear The DOS version of Mastergear was last updated over two years ago, and as such is nowhere near the performance level that the current Windows version is. It has a fair compatibility rate, decent sound, and runs full speed on today's systems. There is a new version, 1.5. MasterGear is shareware, and there is no demo available for this version yet.
Masterlator Masterlator is a Master System & Game Gear emulator project started from scratch in December 2001. Since it is written completely in ANSI C, it needs at least a Pentium II class PC to run smoothly, but it is highly portable across operating systems and processors.
MEKA Zoop's MEKA emulates the Sega Master System, GameGear, SG-1000 and SC-3000 (the last 2 are computers) and also emulates the Colecovision and the Othello Multivision (it's staying in this section for now because SMS/GG is its primary function). It has a KILLER GUI, supports a very wide range of game, has sound support (you have to enable it), and supports many other 'extras' such as joystick support, lightgun emulation, save states, and so much more! I kid you not when I say this: MEKA is the SMS-GG emulator to end all SMS-GG emulators. It's also loaded with hidden 'easter eggs'! Download it now, you won't be sorry!

MEKA has now been ported to Windows as MEKAW. MEKAW is far better for Windows NT/2000/XP users and works on Windows 9x/Me too.

MesaDX This Sega Master System, Game Gear, and Sega Mark III emulator is very good. It's been around for quite awhile now, so give it a try.
MGX I guess everyone knows what DBOY is, so I'll just go ahead and say that this is a Game Gear emulator made by the team behind DBOY. I can't tell you much about it, since the documentation is japanese, but check it out anyway.
NeoSMS This is a new SMS emulator that is already very complete. The compatabilty rate is 96-98%.
Osmose Osmose is a Sega Master System / Gamegear console emulator. The emulator is released as open source project, under GPL license and exists for both Linux and windows.
Past-O-Rama Past-O-Rama is a free Windows9X/DirectX based emulator for the Sega SG1000, Master System, and GameGear systems. It requires at least DirectX 5.0. It plays 99% of tested SG1000 games and many SMS and GG games.
Saya RX-SMS This is a brand new SMS emulator by Kilgamma encoded entirely in OBJ Pascal and compiled with Delphi. It is still in development.
SegaG3 These two emulators are part of a series of japanese *fan98 emulators. They are both for Windows, with SMSFAN98 and GGFan Plus emulating the Sega Master System and GameGear respectively. They are both pretty fast, and should run full speed on a P133. They both have sound support, and I *think* the ability to log MIDIs is included. However, both are shareware, have directional controls disabled, and cost 2000 yen to register. I know nothing else about these emulators, anyone able to translate the documentation, please e-mail me.English documentation is available, courtesy of Issy.
SMaSher This is a new Windows emulator by the same person who brought you the Genesis emulator, Xega. It is still in a relatively primitive state, but it looks promising.
SMS PlusSMS Plus/SDL This is one of the newer Sega Master System/Game Gear emulators around. It runs full speed on any Pentium class machine, and has FM sound support. It has a lower compatibility rate than Massage, but it's still worth checking out for anyone who wants an alternative to Massage.
vbsms+ vbsms+ is an enhanced continuation of the vbsms project by john "brom" casey. It emulates the Sega Mark III, Master System, and Game Gear.
Wakalabis This is a brand new SMS/GG emulator by Adriano Bedeschi & Eduardo Hisashi Sato. It sacrifices speed and performance for compatibility and accuracy. Give it a try!
