Steem SSE is a new version of Steem based on that source release. It incorporates new features and emulation improvements, some of them based on the Hatari  and SainT emulators (this "emulation" goes both ways), some on various internet discussions technical documentation, like chip datasheets, and  tests on real hardware. Steem SSE aims to be the #1 STF/STE emulator. There's no limitation in the original Steem code structure (in C++) that would make that goal unreachable. 'SSE' stands for 'Steven Seagal Edition'. Steven Seagal is a well known Aikido grandmaster, action movie star, musician and playboy. It is rumoured he has a shadowy past working for some secret agencies.  

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.

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.

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.

BizHawk is a A multi-system emulator written in C#. BizHawk provides nice features for casual gamers such as full screen, and joypad support in addition to full rerecording and debugging tools for all system cores.

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)

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.

melonDS is a new emulator project. My goals for it are to do things right and fast.

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. .

There is a new version of one of the oldest, if not the oldest, a frontend for MAME - Mame Classic. MC is terribly annoying to set up, does not like the x64, but the Conservatives have a full range of facilities which allows you to bypass all the arcade machines, which are not included in the canon of author Richard A. Insalaco (NeoGeo ranging from nasty :) :).
