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.

Martin Korth, the author of the popular series of emulators no $ cash (no $ sns, no $ gba, no $ nes, no $ msx, no $ sns, no $ cpc, no $ c64, no $ gmb, no $ k2) has released a new version of the emulator NINTENDO handhelds - GameBoy Advance and Nintendo DS. As in the case of other projects from the NoCash series, the author decided to change access to the newest versions - they are available to everyone, and not as before the previous version was publicly released, and the latest version only for people subsidizing the project. So let's think about http://problemkaputt.de subsidies, considering that Korth creates projects that belong to one of the best emulators of supported platforms, and according to information on his site, subsidies are one of the main sources its maintenance (incidentally, a free man - without a permanent job, without money, Read more

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.

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.

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.
