NetherSX2 Classic
Continuation of NetherSX2 based on AetherSX2 3668
NetherSX2-classic is a companion and variant of NetherSX2 that targets a specific older base version of the AetherSX2 emulator (based on the 3668 branch), applying similar custom patches to provide a stable and performant PS2 emulation environment on Android devices. The project stitches in anti-tampering modifications, RetroAchievements notification fixes, and controller and GameDB updates while maintaining the legacy behavior of the classic build for compatibility with titles that might perform better on the older codebase. Because this classic branch starts from a slightly different upstream version than NetherSX2-patch, users often choose it for performance reasons on lower-power devices or for games with known regressions in newer builds. As with the patch variant, the repository includes configuration changes, fixes for widescreen and deinterlacing behavior, and updated game and controller support developed by the community. -

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. -

Locale Emulator
Yet another system region and language simulator
Locale Emulator is a tool similar to AppLocale and NTLEA, providing a simulation function that can make an application recognize your OS as in a language other than the real one. It is quite useful when you are trying to play country-specific games. Locale Emulator is compatible with the following systems, both 32 and 64-bit, Windows 7 with Service Pack 1, Windows 8.1, and Windows 10. Locale Emulator supports 32-bit executables running on both 32-bit or 64-bit systems. For example, if you are using 64-bit WinRAR, you will not see the context menu on a RAR file unless you swapped 64-bit WinRAR with the 32-bit version. Clone the repo using Git, install Microsoft Visual Studio 2015 / 2017, open LocaleEmulator.sln, perform build action, clone and build the core libraries, and copy LoaderDll.dll and LocaleEmulator.dll from Locale-Emulator-Core to Locale-Emulator build folder. -

emuiibo
Virtual amiibo (amiibo emulation) system for Nintendo Switch
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. -

NetherSX2
Continuation of NetherSX2 based on AetherSX2 4248
NetherSX2-patch is a community-driven continuation and enhancement of the NetherSX2 Android PlayStation 2 emulator, itself a modded fork of the open-source AetherSX2 project originally based on PCSX2. It focuses on providing a more complete and feature-rich experience by applying patches to the upstream emulator build and removing ad-related bloat, fixing notification issues, and exposing many internal settings so users have finer control over performance and compatibility on mobile devices. The project maintains an up-to-date GameDB (game compatibility database), improves controller support, and includes widescreen and no-interlace patches that make many games look and run better on modern screens. Developers also include additional fixes specific to AetherSX2 and NetherSX2 builds, along with tools to resign APKs to avoid Play Protect warnings, which makes installation smoother on Android hardware. -

PPSSPP
A cross-platform PSP emulator
PPSSPP is an open source, cross-platform PSP emulator which allows you to play your PSP games on Android, Windows, Mac or Linux. With PPSSPP you can play your PSP games on your PC in full HD resolution, or play on your tablet for a big-screen mobile gaming experience. PPSSPP enhances the gaming experience in more ways than one. It even upscales some textures that would otherwise be too blurry due to the fact that they were originally made for the small screen. Even on modern Android phones and tablets you can enjoy double the original resolution. Get a whole new and better PSP gaming experience with PPSSPP now! -

Xenia Canary
Xbox 360 Emulator Research Project
Xenia Canary is an experimental fork of the Xenia Xbox 360 emulator that moves faster than the mainline project to trial bleeding-edge improvements. It focuses on game compatibility and performance by iterating quickly on GPU and CPU emulation paths, shader translation, and timing correctness. Canary builds are where risky optimizations, new backends, and rewrites land first so they can be tested by a wider community before stabilizing. The project emphasizes pragmatism: make more titles boot and run with fewer glitches, even if it means carrying experiments that later get refined or rolled back. It also prioritizes developer ergonomics with logging options, debug overlays, and issue templates that help narrow down regressions. While aimed at enthusiasts and testers, it remains a valuable way for end users to play otherwise inaccessible 360 titles on PC when the mainline is lagging behind those fixes. -

PCSX2
The Playstation 2 emulator
PCSX2 is a free and open-source PlayStation 2 (PS2) emulator. Its purpose is to emulate the PS2's hardware, using a combination of MIPS CPU Interpreters, Recompilers and a Virtual Machine that manages hardware states and PS2 system memory. This allows you to play PS2 games on your PC, with many additional features and benefits. The PCSX2 project has been running for more than ten years. Past versions could only run a few public domain game demos, but newer versions can run most games at full speed, including popular titles such as Final Fantasy X and Devil May Cry 3. Visit the PCSX2 compatibility list to check the latest compatibility status of games (with more than 2500 titles tested), or ask for help in the official forums. The latest officially released stable version is version 1.6.0. Installers and binaries for both Windows and Linux are available from our website. -

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. -
