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. -

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. -

VirtualBox
Virtualization software for x86_64 hardware
VirtualBox is a powerful open-source full virtualization software that allows a user to run one or more “guest” operating systems simultaneously inside “virtual machines” on a single physical “host” machine. It supports a wide variety of host platforms (Linux, Windows, macOS, Solaris, etc.) and guest OSes, enabling, for example, running Linux on a Windows PC, running Windows Server on a Linux host, or even legacy OSes in a controlled environment. This flexibility makes VirtualBox ideal for developers, testers, sysadmins, or hobbyists who need different OS environments, want to test software across systems, or need isolation for development, sandboxing, or security experiments. VirtualBox offers both a user-friendly GUI as well as a command-line interface and headless mode, making it useful for desktop usage as well as server or automated environments. -

Proton-GE-Custom
Compatibility tool for Steam Play based on Wine
Proton-GE-Custom is an unofficial compatibility tool for Steam Play that builds on Valve’s Proton and Wine codebases to provide additional patches, fixes, and enhancements for running Windows games on Linux systems through Steam, particularly on Steam Deck and other Linux gaming platforms. Unlike the official Proton builds, this custom fork includes community-developed patches such as media foundation support, raw input improvements, AMD and Nvidia optimizations, and broader compatibility tweaks that help certain games launch and run more reliably or with better performance. It also incorporates a “protonfixes” system that applies per-game adjustments automatically, enabling environment variables or workarounds without manual user intervention. Because it packages its own versions of DXVK, VKD3D, and other components, this tool can resolve glitches or missing features in titles that struggle under standard Proton builds. -

FEX
A fast usermode x86 and x86-64 emulator for Arm64
FEX allows you to run x86 and x86-64 binaries on an AArch64 host, similar to qemu-user and box86. It has native support for a rootfs overlay, so you don't need to chroot, as well as some thunklibs so it can forward things like GL to the host. FEX presents a Linux 5.0 interface to the guest, and supports both AArch64 and x86-64 as hosts. FEX is very much work in progress, so expect things to change. FEX has been tested to build and run on ARMv8.0, ARMv8.1+, and x86-64(AVX or newer) hardware. ARMv7 and older x86 hardware will not work. Expected operating system usage is Linux. FEX has been tested with Ubuntu 20.04, 20.10, and 21.04. Also Arch Linux. AArch64 hosts require a rootfs for running applications. -

BizHawk
BizHawk is a multi-system emulator written in C#
A multi-system emulator written in C#. As well as quality-of-life features for casual players, it also has recording/playback and debugging tools, making it the first choice for TASers (Tool-Assisted Speedrunners). Screenshotting and recording audio + video to file. Firmware management, input, framerate, and more in a HUD over the game. Rebindable hotkeys for controlling the frontend (keyboard+mouse+gamepad). A comprehensive input mapper for the emulated gamepads and other peripherals. Programmatic control over core and frontend with Lua or C#.NET. Development builds are made automatically whenever someone contributes. Because of this, we recommend using a release for work that requires stability (such as TASing), and only switching to a dev build if there's a specific change or addition you need. -

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). -

Ruffle
A Flash Player emulator written in Rust
Ruffle is an open-source emulator for Adobe Flash Player, written primarily in Rust, and targeted at both desktop applications and web browsers via WebAssembly. Its goal is to enable legacy Flash content—animations, games, interactive media—to continue running safely and reliably after official Flash support was discontinued. On the web side, Ruffle is embedded into pages or installed as a browser extension; in the desktop version, it can open .swf files directly or embed them in applications. Because it’s built with memory safety in mind, Ruffle helps avoid many of the security vulnerabilities that plagued classic Flash (buffer overflows, use-after-free, etc.). It strives to support multiple versions of ActionScript (1, 2 and parts of 3) and a wide swath of the Flash API so as much content as possible works unchanged. -

Retrobios
Complete BIOS and firmware packs for RetroArch, Batocera, Recalbox
Retrobios is a low-level systems programming project focused on recreating or emulating BIOS-like functionality for legacy or experimental computing environments. It is designed to provide a minimal firmware layer that initializes hardware and prepares systems to boot, often used for educational purposes or retrocomputing experiments. The project likely explores how early computing systems managed hardware abstraction, memory initialization, and device communication before modern operating systems take control. It emphasizes simplicity and transparency, allowing developers to study and modify core boot processes at a granular level. The architecture is typically close to bare metal, requiring knowledge of assembly language and hardware interfaces. It may also serve as a foundation for building custom operating systems or experimenting with low-level system design. Overall, retrobios functions as a learning and experimentation platform for understanding foundational computing concepts.
