MAME's purpose is to preserve decades of software history. As electronic technology continues to rush forward, MAME prevents this important "vintage" software from being lost and forgotten. This is achieved by documenting the hardware and how it functions. The source code to MAME serves as this documentation. The fact that the software is usable serves primarily to validate the accuracy of the documentation (how else can you prove that you have recreated the hardware faithfully?). Over time, MAME (originally stood for Multiple Arcade Machine Emulator) absorbed the sister-project MESS (Multi Emulator Super System), so MAME now documents a wide variety of (mostly vintage) computers, video game consoles and calculators, in addition to the arcade video games that were its initial focus.

ZEsarux is another multimulator of Sir Clive's machines - we can find practically all models from ZX80, through traditional Sinclair Spectrum models, including those that have already appeared with the Amstrad logo, to the exotic Z88 Cambridge, if not for the lack of QL to say that he emulates everything from this family. Currently, he also manages the Sam Coupe machine or CPC464 (I will not mention other exotics - hence the feature in development). Author also adds Spectrum QL emulation. Emulator, by Cesar Hernandez (this is his second project, after ZXSpectr) was created for Unix, but in time he also made a version for Windows - looking at the list of possibilities, it's quite an interesting harvester, which is worth having at hand if you need all-in - with a rainbow on board - at least it gives me some problems, but what can be liked.

Eighty One is one of the older designs of machine emulators with Z80 on board and quite accidentally with a rainbow in the logo - he can not only pretend the construction from Sinclair ZX80, to Amstrad ZX Spectrum +3 but also familiar with Timex, or more exotic ZX81 - Ringo clones and Lambda.

Pantheon emulates the Acorn Atom, Acorn BBC Micro, Acorn Electron, Atari 2600, Atari 5200, Atari 7800, Atari 800/XE, Atari Lynx, ColecoVision, Magnavox Odyssey 2, MSX computers, and Sega Master System. The emulator will download games from various sources online.

WinUAE is a 32-, 64-bit Windows version (XP/Vista/7/8/10) of the UAE Amiga Emulator. UAE is the collaborative effort of a number of Amiga enthusiasts to create a portable Amiga emulator under the GNU Public License.

Raine (for Rainbow Islands Emulator) is an arcade multiemulator, it can handle games from CPS systems, Taito, Jaleco and it's run titles from NeoGeoCD (in last year project raine and neoraine was combined in one application).

Cemu is the first eighth generation console emulator in the world, specifically the Nintendo Wii U. The requirements are big - at least efficient Core i5 and 6 GB RAM, Nvidia graphics card or AMD with support for OpenGL 4.0 (and if possible, OpenGL 4.5), 64- Windows bit (7, 8.1 or 10). In return, we get the ability to run games smoothly even in 4K resolution (although it is better to have 1080 Ti). Also DRC (GamePad), Pro Controller and Classic Controller controllers are emulated, the keyboard and USB controllers are partially supported.

Emulicious is a free to use multi-system emulator for Windows, Linux, Mac OS(X) and any other operating system supporting Java SE. Emulicious consists of the following emulators: A Nintendo Game Boy Emulator, A Nintendo Game Boy Color Emulator, A Sega Master System Emulator, A Sega Game Gear Emulator. Even though Emulicious aims for precision and cycle accurate emulation it still provides some additional features and tools: Automatic Updates,  Adjustable Turbo,  Adjustable Throttle,  IPS Patching and Savestates (Master System/Game Gear only)
