    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

    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.

    Lakka

    Lakka

    Linux distribution that transforms a computers into game consoles

    Lakka is a lightweight Linux distribution that transforms a small computer into a full-blown emulation console. Built on top of the famous RetroArch emulator, Lakka is able to emulate a large range of hardware and has some useful features such as Braid-like rewinding, joypad hotplug, and video streaming. Lakka is easy to set up and use. Once installed on your SD card, you just have to put your ROM on the card, plug your joypad, and enjoy your favorite old games. We also support PS3 and XBox360 controllers so you don't have to buy new ones. We try our best to keep the hardware required to run Lakka as cheap as possible. The software is optimized to run fast even on low-end computers. The power can be supplied by any micro USB adapter like the one for your smartphone.

    DuckStation

    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.

    Mininet

    Mininet

    Emulator for rapid prototyping of Software Defined Networks

    Mininet creates a realistic virtual network, running real kernel, switch and application code, on a single machine (VM, cloud or native), in seconds, with a single command. Because you can easily interact with your network using the Mininet CLI (and API), customize it, share it with others, or deploy it on real hardware, Mininet is useful for development, teaching, and research. Mininet is also a great way to develop, share, and experiment with Software-Defined Networking (SDN) systems using OpenFlow and P4. Mininet is actively developed and supported, and is released under a permissive BSD Open Source license. We encourage you to contribute code, bug reports/fixes, documentation, and anything else that can improve the system! Links are virtual ethernet pairs, which live in the Linux kernel and connect our emulated switches to emulated hosts (processes).

    Cemu Graphic Packs

    Community Graphic Packs for Cemu

    Use Cemu's built-in graphic packs downloader (a feature added in Cemu 1.15.1) to automatically retrieve the newest graphic packs from our repository. Remove all of your graphic packs first, then move all of the folders from a downloaded .zip below to the graphicPacks folder from your Cemu folder. Choose one of the 3 downloads from above. Each download has a range of versions it supports, pick the one that’s supported by your downloaded Cemu version. Some graphic packs might not be available for Cemu 1.14.0 and newer while previous versions did have graphic packs. This is due to the full reimplementation of the texture system in Cemu 1.14.0. This also changed a lot of the aspects with textures and made all previous graphic packs that changed textures outdated.

    MAME

    MAME

    MAME is a multi-purpose emulation framework

    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. The MAME project as a whole is distributed under the terms of the GNU General Public License, 2 (GPL-2.0), since it contains code made available under multiple GPL-compatible licenses.

    Virtual amiibo (amiibo emulation) system for Nintendo Switch. A virtual amiibo is detected by emuiibo based on two aspects: a amiibo.json and a amiibo.flag file must exist inside the virtual amiibo's folder mentioned above. If (for whatever reason) you would like to disable a virtual amiibo from being recognised by emuiibo, just remove the flag file, and create it again to enable it. While old emuiibo formats are supported and converted to the current format (see above), it is strongly suggested to, unless bin dumps might be indispensable, emuiigen be used, our PC utility designed to create and edit virtual amiibos.
