upterm - A terminal emulator for the 21st century.

•    TypeScript

Upterm (formerly Black Screen) is an IDE in the world of terminals. Strictly speaking, it's both a terminal emulator and an interactive shell based on Electron.

medusa - An open source interactive disassembler

•    C++

Medusa is a disassembler designed to be both modular and interactive. It runs on Windows and Linux, it should be the same on OSX. This project is organized as a library. To disassemble a file you have to use medusa_text or qMedusa. Medusa requires the following libraries: boost >= 1.55 (system, filesystem, thread, date_time), OGDF (required git), and Qt5 >= 5.2 for the GUI. You also need CMake for compilation and a C++11 compiler (VS2015 update 2 on Windows). Git is optional but allows to clone remote repository for specific features, see Compilation/Options.

citra - A Nintendo 3DS Emulator

•    C

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 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.

simplify - Generic Android Deobfuscator

•    Java

Simplify virtually executes an app to understand its behavior and then tries to optimize the code so that it behaves identically but is easier for a human to understand. Each optimization type is simple and generic, so it doesn't matter what the specific type of obfuscation is used. The code on the left is a decompilation of an obfuscated app, and the code on the right has been deobfuscated.

yuzu - Nintendo Switch Emulator

•    C++

yuzu is an experimental open-source emulator for the Nintendo Switch from the creators of Citra. It is written in C++ with portability in mind, with builds actively maintained for Windows, Linux and macOS. The emulator is currently only useful for homebrew development and research purposes.

bap - Binary Analysis Platform

•    OCaml

The Carnegie Mellon University Binary Analysis Platform (CMU BAP) is a reverse engineering and program analysis platform that works with binary code and doesn't require the source code. BAP supports multiple architectures: ARM, x86, x86-64, PowerPC, and MIPS. BAP disassembles and lifts binary code into the RISC-like BAP Instruction Language (BIL). Program analysis is performed using the BIL representation and is architecture independent in a sense that it will work equally well for all supported architectures. The platform comes with a set of tools, libraries, and plugins. The documentation and tutorial are also available. The main purpose of BAP is to provide a toolkit for implementing automated program analysis. BAP is written in OCaml and it is the preferred language to write analysis, we have bindings to C, Python and Rust. The Primus Framework also provide a Lisp-like DSL for writing program analysis tools. BAP is developed in CMU, Cylab and is sponsored by various grants from the United States Department of Defense, Siemens AG, and the Korea government, see sponsors for more information.

jquery.terminal - jQuery Terminal Emulator

•    Javascript

jQuery Terminal Emulator is a plugin for creating command line interpreters in your applications. It can automatically call JSON-RPC service when a user types commands or you can provide you own function in which you can parse user commands. It's ideal if you want to provide additional functionality for power users. It can also be used to debug your application. You can create an interpreter for your JSON-RPC service with one line of code (just use url as first argument).

Ryujinx - Experimental Switch emulator written in C#

•    CSharp

Don't expect much from this. Some homebrew apps work, Puyo Puyo Tetris shows the intro logo (sometimes), and a handful of games boot / work; but that's about it for now. Contributions are always welcome. To build this emulator, you will need the .NET Core 2.1 (RC1) (or higher) SDK. https://www.microsoft.com/net/download/ In release builds, memory checks are disabled to improve performances.
