Genesis emulation is very good, with a high degree of game compatibility (many of them claiming nearly 100% compatibility with commercial games, including Virtua Racing). They are available on many platforms. Many Genesis emulators also feature compatibility with the [[Master System emulators|Sega Master System]] (SMS), and the [[Master System emulators|Game Gear]] (GG) as well as earlier Sega consoles. Genesis-based arcade boards and the [[Sega Pico]] are still sketchy, however. ==DownloadEmulators=={| cellpaddingclass="wikitable" style="text-align:center;"! scope="col"|Name! scope="col"|Platform(s)! scope="col"|Latest Version! scope="col"|CD! scope="col"|32X! scope="col"|[[Sega Pico|Pico]]! scope="col"|[[Libretro|Libretro Core]]! scope="col"|<abbr title="Free/Libre and Open-Source Software">FLOSS</abbr>! scope="col"|Active! scope="col"|[[Recommended Emulators|Recommended]]|-!colspan="410"|PC|-|[[BlastEm]]|align=left|{{Icon|Windows|Linux|macOS}}|[https://www.retrodev.com/blastem/changes.html {{BlastEmVer}}]|{{✗}} ||{{✗}} ||{{✗}} ||{{✓}} ||{{✓}} ||{{✓}} ||{{✓}}|-|[[Exodus]]|align=left|{{Icon|Windows}}|[http://www.exodusemulator.com/index.php/downloads/current-release {{ExodusVer}}]|{{✗}} ||{{✗}} ||{{✗}} ||{{✗}} ||{{✓}} ||{{✗}} ||{{✓}}|-|[[Genesis Plus GX]]|align=left|{{Icon|Windows|Linux|macOS|FreeBSD}}|{{GenPlusGXVer}}|{{✓}} ||{{✗}} ||{{✗}} ||{{✓}}* ||{{{✗}} <ref group=N name=noncomm>While the source is available, its software license explicitly forbids commercial usage of any kind.

For those with [[DualShock 3]] controllers, use [[SCP Driver Package]]==Lock-On Emulation==Lock-On Technology is a unique feature found on Sonic & Knuckles cartridges for the Sega Mega Drive/Genesis that allowed a player to connect an older game to the cartridge's pass-through port for extended or altered gameplay.

PCSX2 is a plugin-based emulator in name only. All plugins are developed in tandem with the emulator in the same source tree. With the exception of some specialized input plugins discussed below, there has not been a reason to add additional plugins such as the older ZeroGS==Mega Drive Plus /ZeroSPU2 for many years. Similar to current versions of Dolphin, the PCSX2 developers intend to eventually have all the plugins statically linked/"baked-in". To facilitate this, PSX emulator support was dropped from LilyPad and GSdx (does not affect playing PSX games in PCSX2). Currently, all plugins except the graphics plugin (GSdx) have been integrated into the core.Genesis Plus==

===Automatic game fixes===Whenever you encounter any kind of bug that isn't graphical in natureCurrently, objects going through other objectsno Genesis + Sega CD emulators feature this function, untargetable objects that should although there is [https://github.com/ekeeke/Genesis-Plus-GX/issues/297 plans to be targetable or A.I. freezing, for example, make sure that the automatic game fixes option from the system menu is activatedadded] in Genesis Plus GX.

===Major graphical glitches=External links==Whenever a game has graphical problems such as garbage texture, missing effects, light sources visible through a wall, burn-in or transparent objects being opaque, the easiest fix is generally to switch to software mode either by pressing F9 in-game or via the configuration panel of the GSdx plugin. If using the DX11 renderer another option is to try the OGL one which is generally more up to date and more accurate. If you're using stable version of the emulator, try using the most recent development build. Newer development builds of the emulator have fixes in the hardware rendering which may remove graphical errors such as red or green bars appearing on the screen. The newest development build can be found at https* [http://pcsx2wiki.netmegadrive.org/download/development/dev-windows.html, click the download link of the revision closest to the top of the pageindex. php?title===Poor performance in software mode===Many games will require you to switch to software mode to fix various issues, albeit at the cost of a significant performance loss. However, an easily overlooked setting in the graphical plugin configuration panel, extra rendering threads, might help lessen the performance loss if you have a quadMain_Page MegaDrive Development Wiki] -core or higher CPU. It is recommended to set it to the number A Wiki about every technical aspect of cores in your CPU minus one if you aren't using the MTVU speed-hack, or minus two if you are (ex: if you are using a quad core CPU you should set this number to 3 without MTVU and 2 with MTVU).The process described above is partially automated in recent development versions of PCSX2 but you might still need to tweak it to get optimal performance levels ===Multi-threaded microVU===Multi-threaded microVU (MTVU), while generally a very useful speed-hack, might sometime cause minor problems like hanging and absence of performance gain or more severe ones like massive performance hits, save-states corruption (PCSX2 keeps a backup you can load with Shift+F3 in case any issues arise) and crashes to desktop. ===Crashes===Crashes could be the results of several things. Switching between SEGA MegaDrive hardware and software rendering rapidly . Its aim is likely to cause provide the emulator to lock up. This can be easily avoided by waiting a few seconds after switching between hardware and software rendering before switching again.If your GPU drivers also crash simultaneously (or you get massive graphical corruption on your desktop and/or a BSOD while trying to run a game) this means you're either using outdated drivers or you're trying to use an AMD card with the OGL renderer and Blending Accuracy set to nonemost detailed, in which case either set it to basic or higher or use the DX11 renderer instead.If the log warns you about TLB miss you are either: * Using a bad dump of a game, in which case you'll need to [[Ripping Games|re-rip your disc]] or re-download the game you are trying to play.* Playing the game directly from your DVD drive, in which case you should [[Ripping Games|rip the game]] accurate and play using the .iso instead (it's not advised up to play directly from your DVD drive).* Trying to play a game that isn't supported by the emulator, in which case you cannot do anything except trying another version of the game (PAL or NTSC-J for example).* Trying to play a game with a massive or in some cases any EE overclock applieddate information, in which case turn it back down the speedhack menu.* You need to check the Wiki to see if the game requires any specific settings regarding the Clamping Mode of the EE/VU.* Ccheats used in the game's .pnach file are invalid. If PCSX2 still crashes after doing all of the above, check that you aren't using any speed-hacks help homebrew development and that your system is stable and not overheating especially if you are overclockingrepairs. ===Extreme fluctuation emulation speed===The large fluctuation in emulation generally are caused by the games themselves and cannot be avoided but there is a handful of cases where this is caused by specific configuration issues * Using large internal resolution multiplier on a lower end GPU, even if the game runs mostly fine some effect can cause the emulator to suddenly have to do a lot of very heavy operation on the VRAM, lower GPU tend to have much lower VRAM bandwidth and will get absolutely crushed by what PCSX2 tries to do, especially true when using Large framebuffer and even more so when using the OGL renderer, obviously the only real fix is turning the resolution down and disabling Large Framebuffer if possible* Playing the game directly from the original DVD using a disc drive, in which case you should [[Ripping Games|rip the game]] and play using the .iso instead* Having the Blending accuracy set too high in the OGL renderer (Full and Ultra mostly)* Using EE overclock in some games ===Intermittent warped audio===Due to how the synchronizing function of the audio plugin works, even when running games on a computer that is capable of going way above 100% speed in a stable fashion, random bits of time-stretched audio can be heard occasionally or even frequently, there are however a few ways to work around that issue.* Set the audio syncing method to Async Mix (can cause Ahttp:/V sync issue, not recommended with rhythm games), do not set it to None as it basically does the same thing as Async Mix but has more issues* Unlock the PCSX2 framerate limiter and use an external one such as MSI Afterburner ===Blurry===It's either interlacing or a filter in the game itself. For the former, switching the de-interlacing mode with F5 may help, and may cause flicker or screen shaking. For the latter, hacks are required. Either Aggressive-CRC if the game is listed there, or skipdraw (toy with the number, 1-100) might work otherwise. ===Black lines===Black lines are caused by scaling to a non-integer internal resolution (anything other than Yx Native), texture filtering (Try anything that isn't bilinear (Forced), improperly offset textures (TC Offset, Wild Arms Offset hacks, Half-Pixel Offset), or improperly handled texture edges (Merge Sprite hack, Sprite/Round Sprite combobox)segaretro. Native resolution, for the most part, fixes these issues, however, software rendering may be required as well. ==Special hardware=====Pressure-sensitive buttons===The DualShock 2 joypad bundled with the PS2 has all buttons and sticks with variable pressure states.  While most PS2 games don't require this feature, instead preferring variable triggerorg/stick pressure (e.g. sneaking past the sleeping dog in Chulip), a select few do. Some examples includeCategory: * All three attack buttons in the Bouncer do different attacks based Mega_Drive_emulators Mega Drive emulators] on whether the press was light, medium or strong. Same goes for the musical game Mad Maestro.Sega Retro* Star Ocean 3 has a musical item that plays different melodies depending on pressure and they're required for progressing. Games requiring variable trigger pressure need physical controllers with analog sticks, but rare are third-party controllers which support variable pressure buttons. To know if your controller supports it, open the LilyPad plugin settings by going to the PCSX2 menu and selecting "Config", "Controllers (PAD)", and "Plugin Settings". At the LilyPad plugin popup, select your gamepad from the list of detected controllers in the "Device Diagnostics" box in the lower left then click the "Test Device" button. A small popup window will appear, showing a list of all the gamepad's buttons as well as their current state. 0.000 = indicates unpressed, 1.000 = indicates fully depressed. Roll either analog stick around. See how the values change from 0.000 to 0.xyz, with the .xyz values shifting incrementally. These changing .xyz values show how the plugin detects different changes in angle as you move the analog stick around. Now press any of the buttons normally used by games, i.e. the triangle/square/cross/circle buttons. See how the values immediately shift from 0.000 = unpressed, directly to 1.000 = pressed. If your gamepad truly has pressure sensitive buttons you will see gradual 0.xyz changes as you slowly press each button, just like the different changes in angle as you move the analog sticks around.If the buttons change from 0.000 directly to 1.000 this proves that your gamepad buttons are not pressure sensitive and are merely tracking the pressed/unpressed state.  The solution would be to either buy an official DualShock 3 controller and use an appropriate 3rd party driver such as [[SCP Driver Package]], or mapping the button to a rarely used trigger/stick in LilyPad this way: An additional button needs to be mapped to circle as well but configured to deliver "light" pressure. This is done by opening the gamepad plugin configuration and choosing a rarely used key - for example, the lower shoulder button L2 - and remapping it to the circle button, and setting the sensitivity to 0.500 or thereabouts. In the game, merely use the remapped L2@circle button to deliver "light" tap/hold tunes while the regular circle button can be used normally to deliver "hard" tap/hold tunes. ==Lightgun support==Lightgun support is available in the pcxs2 emulator via a third party plugin called nuvee.
