mGBA a new Nintendo GameBoy Advance emulator by Jeffrey Pfau written in C, so it should as well do well on slower platforms. The new version, as mentioned by the author, is a set of amendments to improve the stability and compatibility of the emulated console application.

Speccy emulates 16kB, 48kB, and 128kB versions of Sinclair ZX Spectrum, as well as Spectrum +2, +2A, and +3, as well as Timex Sinclair models. Although I had done some ZX-related work in the past and even maintained comp.sys.sinclair FAQ at some point, for many years I abstained from writing a Sinclair ZX Spectrum emulator. It was mostly due to the fact that there are so many other Spectrum emulators around, so writing another one seemed redundant. On the other hand, the lack of a Speccy emulator felt like a gaping hole on my resume :). So, here it is, yet another Spectrum emulator, trivially named Speccy. Currently, Speccy is not a commercial project but rather a test bed to try out different things before introducing them into my other emulators. .

ARCADE is a continuation of the MAMEUIFX project. It is based on the latest MAME source at the time of release.

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.

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).

AppleWin (also known as Apple //e Emulator for Windows) is an open source software emulator. AppleWin was originally written by Mike O'Brien in 1994;[2] O'Brien himself announced an early version of the emulator in 1995, development of AppleWin passed to Oliver Schmidt and is now maintained by Tom Charlesworth. AppleWin has support for most programs that could run either on the Apple II+ or the Apple IIe. By default, AppleWin emulates the Extended Keyboard IIe (better known as the Platinum IIe) with built-in 80-column text support, 128 kilobytes of RAM, two 5¼-inch floppy disk drives, a joystick, a serial card and 65C02 CPU. AppleWin supports lo-res, hi-res, and double hi-res graphics modes and can emulate both color and monochrome Apple II monitors; later versions of AppleWin also can emulate a television set used as a monitor. Both 40-column Read more

Xpeccy is a Linux emulator for machines compatible with ZX Spectrum (primarily Russian clones) and several versions of the machine MSX1, Nintendo GameBoy / GameBoy Color and NINTENDO 8 and its Russian counterpart Dendy. Emulator requires QT library, if we want to run it under Windows, and in return the program offers a few curiosities, for which it is worth to look at it.

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.

Altirra is an 8-bit Atari emulator, thanks to which, on a computer with the Windows operating system, we will launch classic games available exclusively on Atari. The emulator has an internal core, allowing you to run selected games or programs without the need to install ROMs, the manufacturer does not recommend using this solution. He explains that the internal kernel implemented here has been written from scratch, so compatibility issues may occur. The emulator supports disk images saved in the following formats: ATR, DCM, ATX and PRO. You can also make use of Atari (.obx/.xex) executable files.

ColEm is a portable emulator of the old ColecoVision videogame console. It should run most ColecoVision games and supports Coleco's SuperAction controllers with spin wheels.  ColEm is written in portable C and thus can be ported to any sufficiently fast computing platform.
