===XBAND Modem===
All XB∀ND modems plug into the cartridge slot of the console and require their external power supply and a telephone line to connect to. Similar to the Game Genie and other adaptors, a game cartridge is to be placed on top of the XB∀ND modem for the game to function. XB∀ND is the name of a video game modem/online service offered by Catapult in the mid-1990s.

;[[BlastEm]]
:Aims for cycle accuracy but unlike Exodus, aims for lower system requirements and has substantially higher compatibility. Latest stable release is quite old, use nightly or libretro core. BlastEm's own sound implementation is solid, however [https://old.reddit.com/r/emulation/comments/b6ktic/blastem_genmd_emu_062_released/ejlgfi0/ The "it's still a bit less accurate than Nuked" core that can be optionally used in Genesis Plus GX provides more accurate FM emulation than what's in BlastEm at present] but BlastEm's own implementation is solid too and differences . Differences between them are mostly inaudible. Both though and both are way better more accurate than the widely used old MAME sound emulation, which is the default option on Genesis Plus GX too because it's fastcore.;[[Genesis Plus GX]]:A solid emulator for the Sega Genesis / Sega Master System / Sega CD / Game Gear. Made primarily for the Gamecube, it also has a Wii version and a cross-platform libretro core. The only things it lacks are 32X and Pico support, and a native desktop port. The only way to get this emulator on the desktop is to use the aforementioned libretro core, which allows for all the benefits of libretro like EmuVR support, shader presets, dynamic sync, and other [[#Enhancements|enhancements]]. The version used in [[BizHawk]] adds features for speedrunners but only the version used in [[RetroArch]] supports [https://github.com/nukeykt/Nuked-OPN2 Nuked OPN2 cycle-accurate Yamaha YM3438(YM2612)]. The default option for sound emulation, available in all versions, is the old MAME core, because it's very fast.

:Custom fork of Genesis Plus GX available as a libretro core, it includes support for games with enhanced graphics designed for the Firecore system-on-a-chip made by Digital Media Cartridge Ltd.
;[[higan]] / [[ares]]
:Also developing cycle-accurate Genesis emulation, akin to its own [[Super Nintendo emulators|SNES emulator]] core. v130 version brings [https://github.com/ares-emulator/ares/commits/master/ares/component/audio/ym2612 "YM2612 improvement"] and [https://old.reddit.com/r/emulation/comments/xs5tol/ares_v130_released_multi_system_cross_platform/ support for "Mega Mouse"].

;[[PicoDrive]]
:Strongly prioritizes performance over accuracy. Compatibility and accuracy aren't as good as Genesis Plus GX but it's useful on very underpowered systems like the Raspberry Pi Zero. Currently the first and only cross-platform option for Pico games. Libretro and BizHawk versions don't have a stylus or turn page support, while the obsolete standalone version does.
;[[BizHawk]]
;[[Exodus]]
:Exodus is one of the first emulator achieved emulators to attempt cycle accuracy at the high cost of system requirements, but it is no longer updated and far from complete. It is still somewhat useful as a reference for the Genesis hardware, but users will have a faster and more accurate experience with [[BlastEm]] or [[Sega_Genesis_emulators#Emulators|other recommended emulators for Genesis]].
;[http://aamirm.hacking-cult.org/www/regen.html Regen]
;[[MAME]]
:[https://emulation.gametechwiki.com/index.php/[MAME_compatibility_list#Sega_Genesis.2FMega_Drive |Runs most games fine]]. Some don't work that well, but it's got about a [http://adb.arcadeitalia.net/lista_mess.php?software_list_name=megadriv&compatibility= 95% compatibility rate]. Almost all of the C/C-2 arcade games work well in MAME - only the Print Club games don't work. CD emulation not that good, the extra processors throw in more timing problems and 32X emulation has lots of timing issues. There are also suspected SH2 core bugs that come up more frequently on the 32X due to most games being programmed in assembly instead of C like most other SH2 platforms.
;[[mednafen]]
:Mednafen's Sega Genesis/Megadrive emulation is based off of Genesis Plus and information and code from Genesis Plus GX(old GPL-licensed version). The GPL-incompatible CPU and sound emulation cores in the aforementioned projects have been replaced with GPLed or GPL-compatible alternatives; heavily-modified and improved YM2612 emulation from Gens, and Z80 emulation core from FUSE.
:Sega Genesis/Megadrive emulation should still be considered experimental; there are still likely timing bugs in the 68K emulation code, the YM2612 emulation code is not particularly accurate, and the VDP code has timing-related issues.
;[[GENS]]
:Close to Kega Fusion in features and compatibility, but has largely been surpassed by better emulators. There are many different forks and iterations of Gens, so your experience will differ quite a lot depending on which version you use.
;[[Nuked-MD]]
* Supports online and Local Play (up to 2 players);
* Different games between regions (Japan and International)
===Sound emulation===
There are several options to emulate the sound hardware of the Genesis, some of them are shared by more than one emulator.
* '''MAME''' - The old variant of this core is very popular but somewhat inaccurate, however it's very fast and still faithful enough to enjoy games for players less aware of the audio intricacies of the Genesis, as the overall sound character is still there. There's also a new variant of this core, supposedly more accurate, but still not as widespread.
* '''ymfm''' - The core aiming to strike a balance between accuracy and performance, aiming for faithful sound reproduction with only inaudible inaccuracies to speed up the emulation considerably.
* '''Nuked''' - Cycle-accurate core, aiming for the highest accuracy while still being usable in actual games. A go-to option for modern machines.
There are also emulator-specific sound emulation codes of varying accuracy, performance and general quality.

===32X, CD and CD 32X===
:SegaRetro: [https://segaretro.org/Sega_Mega-CD Mega CD], [https://segaretro.org/Sega_32X 32X], [https://segaretro.org/Sega_Mega-CD_32X CD 32X].
The Sega Mega CD, 32X, and Sega CD 32X were add-ons for the Sega Genesis that expanded its capabilities with Mega CD-ROM playback (It can also play Audio CDs and CD+G discs), enhanced processing power, and a limited library of CD-based games with 32X functionality.

===MIDI Keyboard===
MIDI keyboards are used in two special cartridges: ''Miracle Piano Teaching System'', released only in US, and ''Wonder MIDI'', released only in Japan and requires a Model 1 Wondermega (either RG-M1 or HWM-5000) to operate. While MIDI keyboards can be operated with ''MPTS'' as usual, ''Wonder MIDI'' also requires a special disc from the [https://ja.wikipedia.org/wiki/CD-MIDI CD-MIDI] standard to be inserted, as the software itself is not capable to do interactions with the soundchips of both Mega Drive and Mega-CD.
:[https[Wikipedia://en.wikipedia.org/wiki/Miracle_Piano_Teaching_System |Info on ''Miracle Piano Teaching System'' in general]]
:[https://segaretro.org/Wonder_MIDI Info on ''Wonder MIDI'']
===Lock-On===
For GG/AR, the files needed are areplay.bin and ggenie.bin, but most emulators support cheat codes from these natively.
BlastEm also supports the Lock-On Technologyfor Sonic 3, except when combined with Sonic 2, as it does not support lock-on with the sk2chip.bin.

===[https://karmic128.neocities.org/sgflashback/ Firecore]===
Firecore is a system-on-a-chip clone hardware based on the Sega Genesis/Mega Drive system, originating in the late 2000s. Most emulators have not been tested with Firecore-enhanced titles, however it is unlikely that they are supported.
