    NetherSX2 Classic

    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.

    NetherSX2

    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.

    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).

    pfeMAME

    pfeMAME

    Python front end for MAME that can run in Linux, Windows, and MacOS

    pfeMAME is a front end for the Multiple Arcade Game Emulator (MAME) written in (wx)Python. It is cross platform (tested on Linux (Ubuntu), Windows (7, 8, 10, 11), and MacOS. ). It also includes a graphical Tile View designed for MAME cabinets which allows control using joystick / gamepad. It supports favourite game flagging, MESS systems, Software Lists (for systems), per-rom input mapping, and launching of other emulation engines. pfeMAME was written by Gareth Finch and the development project started in 2014 . The goal was to create a MAME front end that was simple, as easy as possible to get into, and had some good documentation. It doesn't provide access to every single MAME option, but pretty much all of the relevant ones you will use from day-to-day. You are free to distribute pfeMAME and modify its source as you wish, however pfeMAME is not to be sold or repackaged for commercial sale.

    Android Emulator Container Scripts

    Android Emulator Container Scripts

    Minimal scripts to run the emulator in a container for various systems

    android-emulator-container-scripts turns the Android Emulator into a cloud-native service you can run in Docker and Kubernetes, so teams can provision ephemeral Android devices on demand. It includes scripts and container images that configure the emulator for headless operation, wire up networking, and expose endpoints for ADB and web access. A built-in WebRTC bridge lets you stream the emulator screen to a browser with interactive input, which is ideal for CI dashboards, remote debugging, or demo environments. The project focuses on reproducibility and scale: you define which system image to boot, how to persist or reset data, and how many instances to run, then schedule them like any other workload. GPU acceleration, audio, and sensors can be enabled depending on your host and cluster capabilities, while fallbacks like SwiftShader keep things usable when no GPU is available.

    PyBoy

    PyBoy

    Game Boy emulator written in Python

    It is highly recommended to read the report to get a light introduction to Game Boy emulation. But do be aware, that the Python implementation has changed a lot. The report is relevant, even though you want to contribute to another emulator or create your own. If you are looking to make a bot or AI, you can find all the external components in the PyBoy Documentation. There is also a short example on our Wiki page Scripts, AI and Bots as well as in the examples directory. If more features are needed, or if you find a bug, don't hesitate to make an issue here on GitHub, or write on our Discord channel. If you need more details, or if you need to compile from source, check out the detailed installation instructions. We support: macOS, Raspberry Pi (Raspbian), Linux (Ubuntu), and Windows 10.
