DeSmuME
DeSmuME is a Nintendo DS emulator
DeSmuME is the most seasoned open source Nintendo DS emulator. It sports tools designed for hackers, speedrunners, youtubers, and casual gamers. Homebrew programs are supported and can even be debugged through GDB. The Windows and OSX versions are both relatively feature rich, and there is a small universe of forks and mods that add even more features for casual gaming. DeSmuME is the origin of RetroArch and OpenEmu Nintendo DS support and is used by several mobile Nintendo DS emulators, with the notable exception of DraStic. DeSmuME's source code is now hosted at https://github.com/TASVideos/desmume/ win32 autobuilds @ https://ci.appveyor.com/project/zeromus/desmume/build/artifacts -

Citra
A Nintendo 3DS Emulator
Citra is an experimental open-source Nintendo 3DS emulator/debugger written in C++. It is written with portability in mind, with builds actively maintained for Windows, Linux and macOS. Citra emulates a subset of 3DS hardware and therefore is useful for running/debugging homebrew applications, and it is also able to run many commercial games! Some of these do not run at a playable state, but we are working every day to advance the project forward. (Playable here means compatibility of at least "Okay" on our game compatibility list.) Citra is licensed under the GPLv2 (or any later version). Refer to the license.txt file included. Please read the FAQ before getting started with the project. If you want to contribute please take a look at the Contributor's Guide and Developer Information. You should also contact any of the developers in the forum in order to know about the current state of the emulator because the TODO list isn't maintained anymore. -

GPCS4
A work-in-progress PlayStation 4 emulator
A PlayStation 4 emulator which was just started. A project done for fun, and for technical research. The only reason I have started this project is for learning 3D graphics. It's not intended to become a serious application. Support simple compute shader, compute ring, cube maps. For more details you could join our discord server to contact me, or if you are used to Tencent QQ/TIM, just join our group. There you can get more resources which are useful for contributing. To run or develop GPCS4, a CPU supporting AVX instruction set as well as a graphics card supporting Vulkan 1.3 are required. -

DuckStation
Fast PlayStation 1 emulator for x86-64/AArch32/AArch64
DuckStation is an simulator/emulator of the Sony PlayStation(TM) console, focusing on playability, speed, and long-term maintainability. The goal is to be as accurate as possible while maintaining performance suitable for low-end devices. "Hack" options are discouraged, the default configuration should support all playable games with only some of the enhancements having compatibility issues. A "BIOS" ROM image is required to to start the emulator and to play games. You can use an image from any hardware version or region, although mismatching game regions and BIOS regions may have compatibility issues. A ROM image is not provided with the emulator for legal reasons, you should dump this from your own console using Caetla or other means. DuckStation features a fully-featured frontend built using Qt, as well as a fullscreen/TV UI based on Dear ImGui. -

Vita3K
Experimental PlayStation Vita emulator
Vita3K is an experimental PlayStation Vita emulator for Windows and Linux. The emulator currently runs some homebrew programs. It is also able to load some decrypted commercial games. Vita3K is licensed under the GPLv2 license. This is largely dictated by external dependencies, most notably Unicorn. Specify the path to a .vpk file as the first command line argument, or run Vita3K --help from the command-line for a full list of options. For more detailed instructions on running/installing games on all platforms, please read the #info-faq channel on our Discord Server. The project is at an early stage, so please be sensitive to that when opening new issues. Expect crashes, glitches, low compatibility and poor performance. -

DeSmuME
DeSmuME is a Nintendo DS emulator
In this version we have added support for high-resolution 3D rendering. Try the new “GPU Scaling Factor” feature to increase the 3D resolution beyond the native resolution of 256×192 pixels. Also, the Cocoa frontend sees continued radical enhancements and while the Windows frontend sees some new incremental enhancements. DeSmuME is a very CPU demanding app. While many users will see DeSmuME as a toy (and use it as such), it is actually a very sophisticated piece of software with lots of features. Also, DeSmuME focuses more on compatibility and features than on speed. Our philosophy is this: You can always mow some extra lawns or babysit some more rugrats to buy upgrades for your computer; but there's nothing you can do to fix compatibility or gain new features. We take care of our side of things, so you should take care of yours. DeSmuME is mostly CPU intensive and less GPU intensive. -

GoBoy
Multi-platform Nintendo Game Boy Color emulator written in Go
GoBoy is a multi-platform Nintendo GameBoy and GameBoy Color emulator written in go. The emulator can run the majority of GB games and some CGB games. There is also colour and sound support. This emulator was primarily built as a development exercise and is still work in progress. Please feel free to contribute if you’re interested in GameBoy emulator development. The program includes debugging functions making it useful for understanding the emulator operation for building one yourself. These functions include printing of opcodes and register values to the console at each step (although will greatly slow down the emulation) and toggling of individual sound channels. GoBoy is compatible with MacOS, Windows and Linux. Building on Windows 10 requires MinGW and on Linux, you’ll need to install gtk. -

achtbit
An 8 bit emulator created on the scratch, including an assembler.
Ever had the experience of a 8 bit system, having max. 64k memory, using assembler to write effective small programs? This system is an experimental 8 bit, 16 color computer, with a processer similar to Z80, that (on my laptop using linux with NO opengl support) achieves up to 1.2 Million instructions per second and 50 Hz. screen refresh rate. It has a builtin assembler to load assembler programs. There is a rudimentary rom that implements some basic functions like line input, or a system clock. Also there is a snake game, (depending on that rom), as a reference and for fun! Take a look, give me your reply! When having ideas for better performance, let me know! -
